Introduction: Herpes Zoster (HZ) is a very painful and debilitating condition caused by the reactivation of the Varicella Zoster Virus (VZV). HZ is characterised by a maculopapular or vesicular rash, usually accompanied by pain that is unilateral and restricted to dermatomes. Post-herpetic Neuralgia (PHN) is defined as pain that persists for more than 90 days after the onset of the HZ rash. Aim: To evaluate the analgesic efficacy of a lidocaine patch in PHN. Materials and Methods: This prospective interventional study conducted at the Department of Anaesthesiology and Critical Care, Pt. BD Sharma, PGIMS, Rohtak, Haryana, India, from February 2020 to March 2021. The study included a total of 24 patients (single group), with a male-to-female ratio of 11:13, aged between 18 and 75 years, all with a Visual Analogue Scale (VAS) score greater than 4. An evaluation of patient pain scores using the VAS and the total number of lidocaine patches used per week for four weeks or until the VAS declined to four was conducted. After obtaining informed and written consent, a medicated 5% lidocaine patch was applied to cover the appropriate area for a minimum period of 12 hours, followed by removal for the next 12 hours. This application continued until the VAS declined to four or up to a maximum of four weeks. The level of significance was set at p≤0.05. Results: In the present study, a total of 24 patients were included. The mean age was 59.5±12.85 years, with 54.2% being female and 45.8% male. The VAS scores at baseline were 8.71±0.999, which reduced to 7.08±1.349 at the end of one week, 5.67±0.007 at the end of two weeks, 4.25±0.442 at the end of three weeks and 3.58±0.830 at the end of four weeks. The VAS scores were significantly lower in all patients over the four weeks (p=0.001). The total number of patches used was 1.88±0.338 at one week, 1.46±0.509 at two weeks, 1.04±0.204 at three weeks and 1.00 at four weeks. The total amount of patches used was significantly reduced over the four weeks (p=0.001). No side-effects related to the lidocaine patch were noted. Conclusion: The 5% lidocaine patch demonstrated good tolerability with a minimal risk of systemic adverse drug reactions and is an effective modality for relieving moderate to severe pain. It is concluded that the 5% lidocaine patch is very effective in the treatment of PHN.

Background: The transversus abdominis plane (TAP) block and local anesthetic wound infiltration have been used to relieve pain after laparoscopic cholecystectomy. This study investigated whether the subcostal transversus abdominis block was superior to traditional port-site infiltration of local anesthetic in reducing post-operative pain, opioid consumption, and time for recovery. Aim and Objectives: To investigated whether the subcostal transversus abdominis block is superior to traditional port-site infiltration of local anesthetic in reducing post-operative pain, opioid consumption, and time for recovery. Materials and Methods: All patients were randomly assigned to two equal groups (n=30) using computer-generated randomization. Patients in Group 1 (TAP group) received a TAP block by administration of 10 mL of 0.5% bupivacaine on each side just before completion of surgery, and patients in Group 2 (local wound infiltration [LWI] group) received 10 mL of 0.5% bupivacaine as a local infiltrate at the local site just before completion of surgery. The pain was measured using a Visual Analog Scale (VAS) at intervals of 30 min to 24 h after the procedure. Results: The mean VAS score was significantly lower in group 1 as compared to group 2 at 2 h and 4 h. Whereas the VAS score was not significantly different post-operative 30 min, 6 h, 12 h, and 24 h. The mean first rescue analgesia was significantly more in Group 1 than in Group 2 (P

Objective To investigate the application effect of transcutaneous electrical acupoint stimulation (TEAS) combined with propofol in painless gastrointestinal endoscopy. Methods A total of 105 patients who underwent gastrointestinal endoscopy were randomly divided into propofol+fentanyl group (P+F group), propofol+TEAS group (P+T group), and propofol+placebo-TEAS group (P+P group), with 35 patients in each group. All patients were induced to deep sedation by the anesthesiologist using propofol before gastroscopy; the patients in the P+F group were given intravenously injected fentanyl 50 μg before gastroscopy, those in the P+T group received placement of electrodes at the acupoints at 30 minutes before examination and were given electrical stimulation till the end of the examination, and those in the P+P group received placement of electrodes at the acupoints alone without electrical stimulation. The patients were recorded in terms of pain score and the amount of propofol used du-ring examination, the time to recovery from anesthesia after examination, and the incidence rate of adverse reactions during or after examination, as well as the degree of satisfaction among patients and physicians. Results Compared with the P+P group, the P+F and P+T groups had a significant reduction in pain score (H=23.16,P0.05), while the P+F group had significantly higher degrees of vertigo, nausea, and vomiting than the other two groups (H=40.97-44.79,P

Background: As it was mentioned, the risk of adverse effects and complications is more than what is expected. Hence, the use of epidural analgesia (EA) was decreased in the management of post-operative pain. Hence, there is a need for another pharmacological agent that is more effective. Manly studies reported that buprenorphine transdermal and sublingual both have significant pain relief scores. Aims and Objectives: The present study was undertaken to compare the pain relief scores of epidural midazolam and buprenorphine for post-operative patients. Materials and Methods: A total of 60 male and female participants, within the age group with the American Society of Anesthesiologists grades I and II were recruited. After recruiting, they were randomly divided into two groups. Soon after the surgery, the pain scores were recorded using the Visual Analog Scale. Soon after recording the pain scores, the corresponding drugs were administered to the participants. Epidural midazolam 30 g/kg and buprenorphine 0.15 mg diluted in normal saline were administered to the corresponding groups for 24 h. Results: There is no significant difference in the demographic data of the participants in both groups. There was no significant difference observed between the two groups. Both are equally effective. Nausea and vomiting are the mild side effects observed in the majority of the patients in both groups. Conclusion: In the present study, we have observed similar actions by both drugs in the management of post-operative pain. The study not only adds to the literature about the effectiveness of these drugs but also explains the mild side effects. Hence, the study recommends the use of both these drugs in the management of post-operative pain so that patient satisfaction can be improved and the patient stay at the hospital can be minimized. Further, detailed and multi-center studies are recommended to generalize the results.

Background: Cardioversion is the treatment of choice in an unstable patient with arrhythmia. It requires analgesia and sedation, which is usually given via intravenous route. However, when there is a failure to get vascular access, alternatives routes to intravenous (IV) sedation and analgesia are needed. Case Presentation: A 59 year old male patient was presented to the emergency department (ED) complaining of chest pain and palpitation. His electrocardiogram (ECG) showed new onset rapid narrow complex atrial fibrillation, which then converted to wide complex tachycardia. Initially, the patient remained hemodynamically stable, but his blood pressure dropped, when cardioversion was indicated. In this case, intranasal (IN) and intraosseous (IO) routes were used, both of which are uncommon to be used for sedation in an unstable patient. The sedatives bioavailability and dosage via non intravenous (non-IV) routes are not commonly used, hence, literature was reviewed to find out the appropriate sedative dosage via non-IV routes specifically in IN and IO route for moderate sedation in ED, to facilitate procedures like cardioversion. Conclusion: It was believed that IN and IO routes are good alternatives to intravenous routes when timely vascular access can't be secured and when emergency medication administration is required.

Abstract The objectives of this prospective, randomized, blinded, crossover, experimental study were to detect the potential anaesthetic- and analgesic-sparing effects of classical music provided to dogs undergoing skin surgery, and to investigate the role of substance P as an intraoperative pain indicator. Twenty dogs were included, each subjected to three different treatments: Chopin music, Mozart music and no music. They were premedicated with acepromazine, butorphanol and meloxicam and anaesthetized with propofol and isoflurane. Fentanyl was used as rescue analgesia. The anaesthetic depth was monitored by using the bispectral index along with standard anaesthetic monitoring, and autonomic nervous system responses were used to monitor the adequacy of analgesia. Furthermore, measurements of substance P serum concentration were carried out. Dogs exposed to music required less isoflurane and fentanyl. Furthermore, a statistically significant effect of time on substance P concentration was observed regardless of exposure to music, and there was a significant interaction effect between different timepoints and the type of acoustic stimulus. Classical music seems to have an isoflurane and fentanyl sparing effect on dogs undergoing minor surgery. Following surgical stimulation, the serum substance P concentration increases rapidly, and thus appears to be a potentially useful pain indicator.

Pain is one of the most common symptoms in pancreatic cancer patients. Pancreatic cancer-related pain has various sources and complex mechanisms, which seriously affects patients' quality of life and adversely affects their prognosis. Effective pain management may prolong the survival of pancreatic cancer patients. Since the pathogenesis of pancreatic cancer-related pain has not been elucidated, part of the pain management may be based on the mechanism, and part of the pain management may be based on physician's experience only. This article discusses both the pathophysiological classification and treatment strategies of pancreatic cancer-related pain, with the aim of providing reference for clinical analgesic practice in pancreatic cancer.

Introduction: Postoperative pain is one of the common causes of increased postoperative morbidity and delayed recovery. Pain causes adverse effects such as hypertension, tachycardia, myocardial ischaemia, decreased alveolar ventilation, poor wound healing, and postoperative morbidity. Vitamin C and N-acetylcysteine (NAC), which is a novel co-analgesic, are being studied to reduce postoperative pain and opioid consumption. Aim: To study the effect of intravenous Vitamin C and NAC on postoperative surgical pain and opioid consumption after laparoscopic gynaecologic oncosurgeries. Materials and Methods: The present study was a randomised controlled study conducted at the Department of Anaesthesiology, Kidwai Memorial Institute of Oncology, Bengaluru, Karnataka, India on 300 patients of American Society of Anaesthesiologists (ASA) physical status 1 and 2 scheduled for laparoscopic Gynaeconcology surgery after obtaining written informed consent. All the selected patients were randomly allocated into three groups. Group P was the control group in Group N patients received intravenous injections of NAC (50 mg/kg) and vitamin C infusion (50 mg/kg) in Group C. Patients were explained about the visual analogue pain scale preoperatively. In the postoperative period, VAS scores were recorded and noted along with the rescue analgesics received and side-effects. Results: Haemodynamic variables were comparable among all three groups. The number of patients who had VAS scores of more than 4 was lower in group C (Vitamin C) at various time intervals when compared to the NAC and placebo groups. It was also statistically significant at 45 minutes, 60 minutes, 90 minutes, 150 minutes, 180 minutes, 300 minutes, and 10 hours (p-value=0.014,

Background: In supraclavicular brachial plexus block, to prolong the duration of analgesia, many adjuvants have been tried in the past in many studies but an ideal adjuvant remains yet to be discovered. Dexmedetomidine, a selective Alfa-2 adrenergic agonist when added to local anesthetic has been reported to prolong the block duration and post-operative analgesia in various regional blocks. Aims and Objectives: The aims and objectives are to study the onset and duration of sensory and motor blockade, postoperative analgesia, and hemodynamic effects of addition of dexmedetomidine with ropivacaine in supraclavicular brachial plexus block. Materials and Methods: Sixty patients aged between 18 and 60 years, American Society of Anesthesiologists class I and II, of both sexes, scheduled for upper limb surgery under supraclavicular brachial plexus block were randomly allocated into 2 groups. Group-A received 20 mL of 0.5% ropivacaine in brachial plexus block with 1 μg/kg dexmedetomidine as adjuvant perineurally and Group-B received 20 mL 0.5% ropivacaine in brachial plexus block with dexmedetomidine intravenous infusion at 1 μg/kg over 10 min. Intraoperatively non-invasive blood pressure, heart rate, SpO2, and sedation were recorded every 5 min for the first 10 min and every 15 min thereafter till the end. Time of first rescue analgesic, intensity of postoperative pain, and total analgesic required were recorded. Results: Onset of sensory and motor block was faster in Group-A than Group-B. Duration of analgesia was prolonged in Group-A than Group-B. Hemodynamic stability was better maintained in Group-A than Group-B. Sedation was better in Group B. Conclusion: Dexmedetomidine as adjuvant to ropivacaine in supraclavicular brachial plexus block is more efficacious in providing faster onset of motor and sensory blocks and prolonging duration of postoperative analgesia with better hemodynamic stability.

Background Each year in England, 450,000 children and young people (CYP) under 18 years of age are transported by ambulance to emergency departments. Approximately 20% of these suffer acute pain caused by illness or injury. Pain is a highly complex sensory and emotional experience. The intersection between acute pain, unwell CYP and the unpredictable pre-hospital environment is convoluted. Studies have shown that prehospital pain management in CYP is poor, with 61% of those suffering acute pain not achieving effective pain relief (abolition or reduction of pain score by 2 or more out of 10) when attended by ambulance. Consequences of poor acute pain management include altered pain perception, post-traumatic stress disorder and the development of chronic pain. This realist review will aim to understand how ambulance clinicians can provide improved prehospital acute pain management for CYP. Methods A realist review will be conducted in accordance with the Realist And Meta-narrative Evidence Syntheses: Evolving Standards (RAMESES) guidance. A five-stage approach will be adopted; 1) Developing an Initial Programme Theory (IPT): develop an IPT with key stakeholder input and evidence from informal searching; 2) Searching and screening: conduct a thorough search of relevant research databases and other literature sources and perform screening in duplicate; 3) Relevance and rigour assessment: assess documents for relevance and rigour in duplicate; 4) Extracting and organising data: code relevant data into conceptual “buckets” using qualitative data analysis software; and 5) Synthesis and Programme Theory (PT) refinement: utilise a realist logic of analysis to generate context-mechanism-outcome configurations (CMOCs) within and across conceptual “buckets”, test and refine the IPT into a realist PT. Conclusion The realist PT will enhance our understanding of what works best to improve acute prehospital pain management in CYP, which will then be tested and refined within a realist evaluation.

Enquadramento: A analgesia loco-regional é um método recomendado no tratamento da dor do pós-operatório. Objetivo: Comparar a eficácia do bloqueio de nervo femoral (BNF) e cutâneo lateral da coxa (CLC); bloqueio do grupo nervoso pericapsular (PENG) e CLC e bloqueio da fáscia ilíaca em doentes submetidos a artroplastia primaria da anca. Metodologia: Estudo analítico-correlacional e retrospetivo, num total de 994 doentes, obtida uma amostra não probabilística por conveniência, de 1 janeiro a 15 outubro de 2023. Foram salvaguardados os princípios éticos. Realizou-se análise descritiva e inferencial com recurso ao programa Python Programming Language (versão 3.12). Resultados: A maioria dos doentes referiu ausência de dor em repouso (82,7%) e dor ligeira em movimento (55,2%). A analgesia de resgate com opioides foi reduzida (7,8%). O grupo de doentes submetidos ao PENG+CLC é aquele que apresenta menor grau de bloqueio sensitivo comparando com o BNF+CLC (p = 0,036). Conclusão: A e‑cácia analgésica é semelhante nas diferentes técnicas. Os resultados sugerem que o PENG+CLC pode resultar numa analgesia eficaz com menos efeitos adversos.

Background: Standard dosages of analgesic and sedative drugs are given to intensive care patients. The resulting range of blood concentrations and corresponding clinical responses need to be better examined. The purpose of this study was to describe daily dosages, measured blood concentrations, and clinical responses in critically ill patients. The purpose was also to contribute to establishing whole blood concentration reference values of the drugs investigated. Methods: A descriptive study of prospectively collected data from 302 admissions to a general intensive care unit (ICU) at a university hospital. Ten drugs (clonidine, fentanyl, morphine, dexmedetomidine, ketamine, ketobemidone, midazolam, paracetamol, propofol, and thiopental) were investigated, and daily dosages recorded. Blood samples were collected twice daily, and drug concentrations were measured. Clinical responses were registered using Richmond agitation-sedation scale (RASS) and Numeric rating scale (NRS). Results: Drug dosages were within recommended dose ranges. Blood concentrations for all 10 drugs showed a wide variation within the cohort, but only 3% were above therapeutic interval where clonidine (57 of 122) and midazolam (38 of 122) dominated. RASS and NRS were not correlated to drug concentrations. Conclusion: Using recommended dose intervals for analgesic and sedative drugs in the ICU setting combined with regular monitoring of clinical responses such as RASS and NRS leads to 97% of concentrations being below the upper limit in the therapeutic interval. This study contributes to whole blood drug concentration reference values regarding these 10 drugs.

Dexmedetomidine, which is an α2 adrenergic receptor agonist with sedative, analgesic, anxiolytic and anti-sympathetic effects, has become a widely used drug in clinical anesthesia and intensive care unit (ICU). Compared with other drugs in the department of anesthesiology, dexmedetomidine has no obvious respiratory depression and no obvious hemodynamic changes, and can significantly reduce the dosage of sedative and analgesic drugs when combined with other anesthetics. In clinical applications, dexmedetomidine has been found to induce a sedative response that is associated with rapid arousal. Dexmedetomidine is traditionally thought to act through α2 adrenergic receptors to lower blood pressure, dilate blood vessels and lower heart rate, but it is unclear how it affects neural circuits in the brain. In recent years, there has been an increasing number of studies on the mechanism of action of dexmedetomidine, which has confirmed that the ventrolateral preoptic nucleus (VLPO), locus coeruleus (LC) and ventral tegmental area (VTA) of the hypothalamus are involved in the sedation mediated by dexmedetomidine, the dorsal root ganglion (DRG) and superior cervical ganglion (SCG) are involved in dexmedetomidine-mediated analgesia, and the hypothalamic preoptic area (PO) and hypothalamic paraventricular nucleus (PVN) are involved in the changes in body temperature and water-electrolyte balance mediated by dexmedetomidine, providing a new direction for understanding the mechanism of dexmedetomidine in the central nervous system.

Introduction: Regional anaesthesia is the standard technique for lower limb infraumbilical procedures. To provide a better analgesic profile, adjuvants are added to local anaesthetics to enhance their action. Opioids have been used as an adjuvant for a long-time. With evolving pharmacology, various drugs satisfy the criteria of being an adjuvant. One such drug is Dexmedetomidine, a novel alpha-2 agonist. Aim: To compare the duration of analgesia of intrathecal Morphine and Dexmedetomidine as an adjuvant to bupivacaine in a subarachnoid block for lower limb infraumbilical surgeries. Materials and Methods: In this randomised clinical, double-blinded study conducted in a multispecialty hospital over the period of June 2020 to February 2021, 70 patients were randomly divided into two groups: Group M received Morphine 125 μg, and Group D received dexmedetomidine 5 μg as an adjuvant to 15 mg of 0.5% hyperbaric bupivacaine. The primary outcome was to compare the duration of postoperative analgesia. The secondary results assessed the block characteristics, haemodynamic parameters, rescue analgesic consumption, sedation score, and side-effects like bradycardia, hypotension, nausea, vomiting, pruritus, and respiratory depression. Data was spread in an Excel sheet and descriptive analysis done. Normally distributed continuous variables were compared using a Student’s t-test, and discrete variables were compared using a Chi-square test. A p-value of

Background This study investigated the relationship between intraoperative requirement for an inhalational anesthetic (sevoflurane) or an opioid (remifentanil) and postoperative analgesic consumption. Methods The study included 200 adult patients undergoing elective laparoscopic colectomy. In the sevoflurane group, the effect-site concentration of remifentanil was fixed at 1.0 ng/ml, while the inspiratory sevoflurane concentration was adjusted to maintain an appropriate anesthetic depth. In the remifentanil group, the end-expiratory sevoflurane concentration was fixed at 1.0 vol.%, and the remifentanil concentration was adjusted. Pain scores and cumulative postoperative analgesic consumptions were evaluated at 2, 6, 24, and 48 h after surgery. Results Average end-tidal concentration of sevoflurane and effect-site concentration of remifentanil were 2.0 ± 0.4 vol.% and 3.9 ± 1.4 ng/ml in the sevoflurane and remifentanil groups, respectively. Cumulative postoperative analgesic consumption at 48 h postoperatively was 55 ± 26 ml in the sevoflurane group and 57 ± 33 ml in the remifentanil group. In the remifentanil group, the postoperative cumulative analgesic consumptions at 2 and 6 h were positively correlated with intraoperative remifentanil requirements (2 h: r = 0.36, P < 0.001; 6 h: r = 0.38, P < 0.001). However, there was no significant correlation in the sevoflurane group (r = 0.04, P = 0.691). Conclusions The amount of intraoperative requirement of short acting opioid, remifentanil, is correlated with postoperative analgesic consumption within postoperative 6 h. It may be contributed by the development of acute opioid tolerance. However, intraoperative sevoflurane requirement had no effect on postoperative analgesic consumption.

Background This study aimed to evaluate the relationship between postoperative pain and circadian rhythm after pediatric acute appendicitis surgery. Methods Two hundred patients, aged 6–18 years, undergoing acute appendicitis surgery were included in this prospective observational study. The patients were divided into four groups according to the time they underwent surgery: the night group, 01:01–07:00; morning group, 07:01–13:00; afternoon group, 13:01–19:00; and evening group, 19:01–01:00. Intraoperative and postoperative vital signs, postoperative 24-h Wong–Baker Faces Pain Rating Scale (FACEs) scores, and the amount of analgesic required were recorded. Results A total of 186 patients were analyzed in the study. There was no statistically significant difference in the demographic characteristics of the patient groups. Additionally, no differences were observed in intraoperative and postoperative vital signs among the four groups. However, patients in the night group had significantly higher FACEs values than those in the other groups at each time point (1st, 3rd, 6th, and 12th h) up to 12 h (P = 0.007, P = 0.023, P = 0.048, and P = 0.003, respectively). The amount of analgesic required in the night group was statistically higher than in the other groups until 12 h (P = 0.002, P < 0.001, P = 0.002, and P = 0.004, respectively). Conclusion A relationship was found between acute appendicitis operations performed at night (01:01 to 07:00) under general anesthesia and circadian rhythm in children. We believe that considering circadian time in the relief of postoperative pain would be beneficial.

Introduction: Percutaneous Nephrolithotomy (PCNL) is a minimally invasive procedure for the treatment of renal stone disease, usually performed under General Anaesthesia (GA). Regional anaesthesia, specifically Thoracic Segmental Spinal Anaesthesia (TSSA), offers a suitable alternative to mitigate complications associated with GA. TSSA in PCNL has an advantage over conventional lumbar spinal anaesthesia in terms of better haemodynamic stability, attributed to the lesser amount of local anaesthetic drug required. However, its clinical utility is yet to be fully explored. Aim: To investigate the feasibility and efficacy of TSSA in patients undergoing PCNL by analysing their medical records. Materials and Methods: A retrospective observational study was conducted on 250 patients from January 2022 to July 2023 at GNRC Medical, Guwahati, India. Patients aged 20-70 years with American Society of Anaesthesiology (ASA) I and II classification, undergoing PCNL with renal stones ≤40 mm, were included. TSSA was administered at the T9-T10 intervertebral space. Intraoperative parameters, degree of motor and sensory block, post-operative analgesia, patient and surgeon satisfaction were recorded. Descriptive statistics of the study were analysed in Microsoft excel and presented as mean with standard deviation or as numbers and percentages. Results: The patients in the study had a mean age of 41.08 years, Body Mass Index (BMI) of 25.52 kg/m2, stone size of 25.73 mm, and surgical duration of 74.92 minutes. TSSA was associated with minimal intraoperative hypotension (6%) and bradycardia (8.9%), zero incidences of neurological complications, and did not require conversion to GA. Complete stone clearance was achieved in 89.6% of cases. Post-operative analgesia was excellent in 179 (71.6%) patients as they did not require any rescue analgesia within the first 24 hours. Patient and surgeon satisfaction were notably high. Conclusion: TSSA emerges as a safe and efficient alternative to GA in selected cases of PCNL. Patient and surgeon satisfaction, along with minimal post-operative complications, support its consideration and usage. However, the choice of anaesthesia should be individualised based on procedural complexities and patient characteristics.

Background: Bladder exstrophy is a complex, rare congenital malformation with an incidence of 3.3 cases in every 100000 live births and is slightly more common in males. Primary surgical repair requires many hours of surgery with fluid and blood loss. Because of wide fluctuations in hemodynamics, a longer duration of surgery, smaller age, risk of hypothermia and post-operative intensive care may be required. We evaluated the use of continuous caudal epidural infusion of bupivacaine and fentanyl under general anesthesia for urinary bladder exstrophy-epispadias surgery in children. Aims and Objectives: Aim of the study was to evaluate the postoperative analgesia in patients undergoing surgery for bladder exstrophy. The primary objective was to assess the postoperative pain using FLACC scale and sedation score after successful caudal administration. Secondary objective was to assess the hemodynamic changes after caudal administration. Materials and Methods: A total of 13 patients aged between 9months and 13 years of either sex, weighing between 5kg to 30kg, belonging to ASA grade II to IV, underwent surgery for epispadias–exstrophy complex. Initial bolus 0.75ml/kg of 0.25% bupivacaine with fentanyl 1ug/kg was given through epidural. Postoperative analgesia was maintained by continuous infusion of 0.0625% bupivacaine @0.1ml/kg/hr in young children and 0.125% bupivacaine with fentanyl 1ug/ml in older children for 4-5 days with the help of ON-Q pump or infusion pump. Baseline hemodynamic parameters including MAP, heart rate and SpO2 was recorded at various time intervals. Postoperative pain was assessed using face, legs, activity, cry and consolability (FLACC) pain scale and sedation score was assessed by using ramsay sedation score. Results: There was a statistically significant decrease in mean pulse rate in the study group from baseline to thirty minutes after reversal (p

Background. Postoperative analgesia in kidney transplant recipients is challenging due to potential nephrotoxicity of nonsteroidal anti-inflammatory drugs and the reduced clearance of opioid metabolites during transient renal impairment. Opioid-sparing multimodal postoperative analgesia using regional analgesia methods could provide better pain control and early activation after kidney transplantation.Aim. To evaluate the clinical results of treatment using regional pain management methods in kidney transplant recipients.Material and methods. A single-center study was conducted at Republican Research Center of Emergency Medicine from 2020 to 2022. The study included 97 patients who underwent heterotopic kidney transplantation from a living related donor. Patients were divided into 3 groups. In group 1 (31 patients), general anesthesia was used. For postoperative analgesia opioid analgesics in combination with metamizole 1000 mg were used. In group 2 (33 recipient patients), a combination of general anesthesia and open transversus abdominis plane block was used. In group 3 (33 recipient patients), a combination of general anesthesia and erector spine plane block was performed. Opioid analgesics were used as a "rescue analgesia" when necessary. The primary study end points were the pain intensity assessed by a visual analogue scale and opioid consumption on the first day after surgery. Secondary endpoints were the time of intestinal motility recovery, the presence of nausea and vomiting, the Intensive Care Unit length of stay and the hospital length of stay.Results. Pain intensity 6 hours after surgery in patients of group 1 was 13.5% and 24.6% higher than in patients of group 2 and 3, respectively. In group 2, pain intensity was 12.8% higher compared to group 3 (p=0.0017). At 12 hours after surgery, the pain intensity was 42% higher in group 1 compared to group 2 and group 3 (p

Background: For intraocular surgery, the optimal local anesthetic agent must have a rapid onset of action and a sufficient duration of effect so as to enable a painless, motionless procedure without prolonging akinesia. Aims and Objective: This prospective, comparative observational study compares ropivacaine and 0.5% bupivacaine for cataract surgery peribulbar block. Hyaluronidase is utilized in both groups because it promotes local anesthetic diffusion. Material and Methods: Present prospective, observational, comparative study performed at the Department of Anesthesia Tertiary Care Teaching Institute of India for the duration of 1 year. All eligible patients were allocated in two groups as GROUP B and GROUP R. GROUP B: 10 mL of 0.5% bupivacaine and 15 I.U./mL of hyaluronidase. GROUP R: 10 mL of 0.5% ropivacaine and 15 I.U./mL of hyaluronidase. Patients were assessed for sensory block, eyelid, and ocular movements at an interval of 2 min, and Visual Analog Scale score for pain assessment. Results: Age and gender did not differ significantly between the two study groups, according to the findings. Comparable and similar patient characteristics distinguished the two study groups. (P>0.05). The difference in onset of eyelid motor blockade between the two groups was not statistically significant. The difference in the onset of motor blockade [ocular movement] between the two groups was not statistically significant (P>0.05). (P>0.05) Analgesia duration differed significantly between the two groups in a statistical sense. Ropivacaine exhibits a significantly prolonged duration of analgesic effect than bupivacaine (P≤0.05). Conclusion: Peribulbar block utilizing 0.5% ropivacaine is a more favorable and secure option for a local anesthetic that effectively extends postoperative pain alleviation, in comparison to the use of 0.5% bupivacaine.

Objective: To compare the outcomes of transversus abdominis plane (TAP) block versus local wound infiltration (LAI) for postoperative analgesia in patients undergoing total abdominal hysterectomy (TAH). Methods: This randomized controlled trial was conducted at Dr. Ziauddin Hospital & Medical College, Karachi, Pakistan from December 2023 to May 2024. Female patients aged 18 to 50 years, and scheduled for TAH under general anesthesia were included. Patients were randomly allocated to the TAP group or the LAI group using sealed opaque envelopes. The primary outcome was pain score at different time intervals postoperatively. Pain score measured using the Visual Analogue Scale. Secondary outcomes included total analgesia consumption within 24 hours. Results: Of total 100 patients, the median (IQR) age was 50.0 (47.2-55.0) years. At 8 hours postoperatively, the median pain score was significantly lower in the TAP group 0.0 (0.0-1.0) compared to the LAI group 1.0 (0.0-2.0) (p-value

Objective: The purpose of this study was to determine the analgesic effect of a flurbiprofen ester injection via continuous intravenous drip during transvaginal 4-dimensional hysterosalpingography (TVS 4D-HyCoSy). Methods: Two hundred thirty patients who underwent TVS 4D-HyCoSy for infertility from May 2018 to August 2021 at our hospital were selected. The participants were grouped based on tubal patency, flurbiprofen ester use, and uterine cannula diameter, as follows: bilateral tubal patency group; non-bilateral tubal patency group; atropine group; atropine + flurbiprofen ester group; coarse tube group; and fine tube group. The analgesic effect during TVS 4D-HyCoSy and pain relief were compared between groups using visual analog scoring (NRS). Additionally, the incidence of adverse effects was recorded and factors related to the influence of pain were analyzed. Results: 1. Tubal patency reduced pain during ultrasound tubal examination, flurbiprofenate provided significant analgesia after ultrasound tubalography and reduced adverse effects (P < 0.001). 2. The tube diameter thickness had no effect on tubal ultrasonography procedure-related pain. 3. Multivariable analysis of pain relief during imaging suggested that the use of flurbiprofen for bilateral tubal patency had a significant positive effect on pain relief within 30 min after the examination with an AUC of 0.732 (95% CI: 0.665–0.798). Conclusion: A flurbiprofen ester continuous intravenous drip had a good analgesic effect in patients with TVS 4D-HyCoSy. Specifically, the pain relief effect after examination was significant and reduced the incidence of adverse reactions during the contrast examination. Flurbiprofen ester can be administered independently and is worthy of clinical promotion and application.

BACKGROUND AND OBJECTIVES: Spine diseases have a high annual prevalence and are the main causes of years lived with disability and chronic pain. Among the postoperative analgesic control options, patient-controlled analgesia (PCA) and multimodal analgesia (MMA) have shown good clinical results. This meta-analysis seeks new evidence to help in the treatment of acute postoperative pain in patients undergoing spinal surgery. CONTENTS: The following databases were used: Cochrane Central Register of Controlled Trials, Medline and Embase. Studies that compared two post-surgical analgesic interventions were included; MMA and PCA. The parameters evaluated were: analgesic effect; opioid consumption; length of hospital stay; and adverse effects. Registration of the systematic review protocol: (PROSPERO CRD42023446627). There was no statistical difference when assessing analgesic improvement comparing MMA to PCA (MD -0.12 [-0.41, 0.17] 95%CI with p=0.69). There was a statistical difference, with lower opioid consumption in MMA compared to PCA (MD -3.04 [-3.69, -2.39] 95%CI with p=0.0002). Statistically significant difference regarding length of hospital stay in favor of MMA (MD -13.17 [-16.98, -9.36] 95%CI with p=0.00001), and significantly lower incidence of nausea and vomiting in patients undergoing MMA in compared to PCA (OR 0.26 [0.11, -0.64] 95%CI with p=0.003). CONCLUSION: MMA was equivalent to PCA in the treatment of acute postoperative spinal pain, with the significant clinical advantage and safety of lower amounts of infused opioids, shorter hospital stay and lower incidence of adverse effects.

Objective: This study aimed to evaluate the analgesic efficacy of preoperative fascia iliaca compartment block (FICB) in terms of preoperative pain score reduction in geriatric hip fracture patients. Secondary objectives were to compare opioid consumption, procedure-related complications, and patient outcomes. Materials and Methods: This single-center retrospective study included patients aged 65 or older with hip fractures who experienced moderate to severe pain in a tertiary care university hospital from January 2019 to July 2021. The variables collected for analysis were patient baseline characteristics and the pain score at rest, including during movement from the beginning of service and subsequently each morning after admission until the day of surgery. Results: A total of 439 patients were included in this study, 109 patients (24.8%) receiving preoperative FICB (FICB group). When comparing the FICB and non-FICB groups, a significant reduction in pain scores was observed on postadmission day 1, both at rest (0 [IQR=0-4] vs. 0 [IQR=0-2], p

Objective To evaluate ultrasound guided cervical nerves pathway block (CNPB) for internal jugular vein cannulation in awake patients. Methods A total of 100 patients who underwent elective jugular vein puncture and catheterization at Nanjing Pukou District Hospital of Chinese Medicine from June to December 2021 were selected and divided into ultrasound guided CNPB group (group B, n=50) and local infiltration anesthesia group (group C, n=50). Both groups underwent internal jugular vein catheterization under ultrasound guidance. The outcome indicators were the Numeric Rating Scales (NRS), Bruggrmann Comfort Scale (BCS), hemodynamic parameters, sleeping quality, and the complications. The results were recorded in the morning of the cannulation operation (T0), during the operation (T1), 5 min after the cannulation (T2), that night of the cannulation (T3), postoperative day 1 (T4), postoperative day 2 (T5). Results The NRS of group B were significantly lower than that of group C at T1 and T3. The BCS of group B were higher than group C at T1, T2, T3, and T4. The heart rate and systolic blood pressure at T1 in group B were dramatically lower than group C. At T3 and T4, sleeping quality of group B was better than group C (P＜0.05). Conclusion Ultrasound guided CNPB, as the anesthesia for internal jugular vein cannulation in awake patients, can effectively reduce the NRS scaling and improve the BCS and sleeping quality without obvious adverse reactions.

Abstract Background Effective pain control is crucial to optimise the success of medical procedures. Immersive virtual reality (VR) technology could offer an effective non-invasive, non-pharmacological option to distract patients and reduce their experience of pain. We aimed to evaluate the efficacy of Immersive virtual reality (VR) technology in reducing patient’s pain perception during various medical procedures by conducting a systematic review and meta-analysis. Methods We searched MEDLINE, EMBASE, CENTRAL, CINAHL, and SIGLE until December 2022 for all randomised clinical trials (RCT) evaluating any type of VR in patients undergoing any medical procedure. We conducted a random effect meta-analysis summarising standardised mean differences (SMD) with 95% confidence intervals (CI). We evaluated heterogeneity using I 2 and explored it using subgroup and meta-regression analyses. Results In total, we included 92 RCTs (n = 7133 participants). There was a significant reduction in pain scores with VR across all medical procedures (n = 83, SMD − 0.78, 95% CI − 1.00 to − 0.57, I 2 = 93%, p =

Aim. To study the impact of various methods of perioperative pain management on the frequency of postoperative complications in patients with lung cancer after thoracotomy. Materials and methods. The study involved 157 patients who were divided into 4 groups. Multimodal analgesia (MA) group: according to the concept of preemptive analgesia, patients received 1000 mg paracetamol IV 1 hour before surgery and 50 mg dexketoprofen IV; in the postoperative period, dexketoprofen and paracetamol were administered every 8 hours as well as epidural analgesia: 40 mg of 2 % lidocaine solution after a catheter was placed and continuous ropivacaine infusion at a dose of 2 mg/ml (6–14 ml/h) in the postoperative period. Thoracic epidural analgesia (TEA) group: epidural analgesia: administration of 40 mg of 2 % lidocaine solution after catheter placement, continuous ropivacaine infusion in the postoperative period at a dose of 2 mg/ml (6–14 ml/h). Preemptive analgesia (PA) group: according to the concept of preemptive analgesia – 1000 mg IV paracetamol 1 hour before surgery as well as 50 mg IV dexketoprofen; in the postoperative period, dexketoprofen and paracetamol were administered every 8 hours. Control group (C): patients received 50 mg IV dexketoprofen for postoperative analgesia. If the severity of the pain syndrome was more than 50 mm according to the visual analogue scale (VAS), patients of all groups were given 10 mg IV morphine. The study involved the registration of side effects in the postoperative period. Results. Among 157 patients, complications in the postoperative period were observed in 61 patients (38.85 %). The frequency of complications in MA group was 10.8 % of the total number of patients, in TEA group – 12.7 %, PA – 6.4 %, and in C group – 8.9 %. The most common complaint among TEA group patients was injection-site itching (13.5 %). PA group patients had a significantly lower number of complications compared to TEA group (p = 0.035). There was no statistically significant difference in the frequency of nausea or urinary retention in patients of all groups (p > 0.05). No difference was noted in the number of pulmonary complications depending on the method of perioperative analgesia (p > 0.05). 31 patients (75.6 %) of PA group did not have any complications, that was significantly different from TEA (p = 0.021) and MA (p = 0.039) patient groups. Conclusions. The use of paracetamol and dexketoprofen combination in the perioperative period allows to reduce (p = 0.035) the total number of postoperative anesthetic complications compared to the use of only thoracic epidural analgesia. The use of a multimodal approach combining epidural analgesia and administration of paracetamol and dexketoprofen does not reduce (p > 0.05) the overall frequency of complications compared to patients without epidural analgesia.

Introduction: Epidural anaesthesia is a boon for providing prolonged analgesia for postoperative pain relief. The influence of epidural needle insertion on the onset of the block, which has not been studied previously, is significant. Aim: To analyse the effect of epidural needle entry and rotation of the needle on the onset and duration of the block. Materials and Methods: This double-blinded randomised controlled trial was conducted at the Department of Anaesthesiology, SRM Institute of Science and Technology, Chennai, Tamil Nadu, India from March 2020 to August 2021 on 70 patients undergoing leg and ankle surgeries. They were randomised into Group-ML (midline approach) and Group-PM (paramedian approach). In Group-ML, midline epidural needle entry was followed by catheter insertion. In Group-PM, the needle entry was paramedian, and the bevel was turned 45º towards the surgical site for catheter insertion. A 10 mL of 0.5% bupivacaine was administered. Postoperatively, epidural infusion was initiated using 0.125% bupivacaine with 2 μg/mL fentanyl. The time taken for catheter placement, onset of motor and sensory blockade, maximum sensory level attained, duration of sensory blockade, consumption of local anaesthetics, haemodynamic profile, and the need for rescue analgesia were monitored. Continuous data were analysed using the Student's t-test, and categorical data were analysed using the Chi-squared test with International Business Machines (IBM) statistical product and service solutions software version 27.0 Results: Both groups were comparable with respect to demographics. The mean age in Group-ML was 40.9±25.93 years, while in Group-PM it was 41.028±20.576 years, with a p-value of 0.981. The mean BMI in Group-ML was 24.91±2.998 kg/m2, while in Group-PM it was 24.96±2.527 kg/m2, which was statistically insignificant with a p-value of 0.944. A total of 21 males in Group-ML and 28 males in Group-PM participated in the study; the distribution was found to be statistically insignificant with a p-value of 0.067. The time taken for the placement of the epidural catheter was around 288 seconds in Group-ML and 322 seconds in Group-PM, with a p-value of 0.0035. The onset of sensory block was around 17 minutes in Group-ML and 13 minutes in Group-PM, respectively, with a p-value of 0.0001. The duration of sensory block or the time taken for two-segment regression of level was around 102 minutes and 128 minutes in Group-ML and Group-PM, respectively (p-value 0.0001). The rescue analgesic was required in seven patients of Group-ML and none in Group-PM, with a p-value of 0.005. The haemodynamic profile intra and postoperatively and postoperative VAS score were statistically insignificant between the groups. Conclusion: The paramedian approach and epidural catheter insertion with the needle rotated at an angle of 45º towards the surgical side provide a rapid onset of the sensory and motor block with extended duration of the sensory blockade and reduced consumption of local anaesthetics.

The brachial plexus block is a flexible and reliable regional anesthetic method with a wide range of applications. In this study, we aim to determine whether nalbuphine in combination with the local anesthetic bupivacaine could increase the efficacy and duration of analgesia during ultrasound-guided blockade of the brachial plexus. Seven randomized and controlled trials involving 416 patients were included after searching PubMed, Google, and Web of Science. Results of the studies were then retrieved and effect sizes were calculated using Review Manager 5. Duration of analgesia was significant heterogeneity between studies (P

Background Pivotal meridian massage for neuropathic pain obtained favorable results in recent years, however, its specific mechanism of action has not been fully elucidated. Objective To observe the analgesic effect of pivotal meridian massage on rats according to the research indexes taking rat model of neuropathic pain induced by L5 spinal nerve ligation as the object of observation, to further investigate whether the analgesic effect is achieved by affecting LncRNA-GAS5 and then regulating the apoptosis of neurons in the dorsal horn of the spinal cord. Methods The experiment was conducted from January to June 2021 at the Experimental Center for Animal Medicine of Guangxi University of Chinese Medicine and Guangxi University. A total of 120 healthy female SD rats were randomly divided into the normal group, model group, sham-operated group, sham-manipulation group, and meridian manipulation group, with 24 rats in each group. Rat model of neuropathic pain was prepared by ligating the L5 spinal nerve in the model, sham-operated, sham-manipulation and meridian manipulation groups. After modeling for 24 hours, the L5 spinal nerve was exposed for a few minutes without ligation, and the wound was closed layer by layer in the sham-operated group; hind limbs of the rats in the sham-manipulation group were gently stroked for 18 minutes; a self-made massager was used to sequentially stimulate the three acupoints on the bilateral Foot Shaoyang Gallbladder Meridian of Huan Tiao, Yang Ling Quan, and Xuan Zhong, with a stimulation force of 5 N, frequency of 2 Hz, intervention of 1 minute for each acupoint and technique, totaling 18 minutes in the meridian manipulation group. The normal group and model group were fed and observed normally without any intervention. Behavioral tests (mechanical withdrawal threshold and thermal withdrawal latency) were performed before modeling and on days 1, 3, 7, and 14 after modeling. On days 7 and 14 of the intervention, 12 rats were randomly selected for tissue sampling to detect the expression of TLR8/ERK signaling pathway-related proteins (Bcl-2, Caspase-3, ERK, TLR8 protein levels) and the expression levels of LncRNA-GAS5 and miR-21 genes in the spinal cord tissue. Results (1) In terms of behavioral observations, the mechanical withdrawal threshold of the model group, sham-manipulation group, and meridian manipulation group was lower than the normal group on days 1, 3, 7, and 14 after modeling (P

Background: Various adjuvants have been added in Brachial plexus block but only few studies have reported the use of dexmedetomidine. Alpha 2 agonist Dexmedetomidine used as an adjuvant to the local anesthetic has been suggested to prolong the duration of peripheral nerve block. The objective of this study is to compare the effect adding Dexmedetomidine to Ropivacaine in Supraclavicular brachial plexus block Materials and Methods: A Quantitative, comparative cross sectional prospective study was conducted in 78 patients randomly allocated into three groups. Group R received 30ml of 0.5% Ropivacaine, Group B received 30ml of 0.5% Ropivacaine + 50mcg of Dexmedetomidine for supraclavicular block and Group Y received 30ml of 0.5% Ropivacaine 0.5% for supraclavicular block and intravenous Dexmedetomidine 50mcg . The onset time to sensory and motor blockade, duration of sensory and motor block and duration of analgesia were recorded. Results: The onset of Sensory block and motor block was earlier in group B than in group Y and group R. The duration of sensory block and motor block duration was also prolonged in group B when compared with group Y and group R. The duration of analgesia was significantly longer in group B, and group Y when compared to group R. Conclusion: Dexmedetomidine as an adjuvant to Ropivacaine decreases the sensory as well as motor block onset time, prolongs sensory and motor block duration and also increases the duration of analgesia. The action of Dexmedetomidine most probably is local rather than centrally mediated.

Pain has a certain number of physical, psychological and social consequences. Pain is of particular importance in the postoperative period for patients with tumors of the oral cavity and of the oropharynx. The effectiveness of analgesia in the postoperative period is a serious problem in maxillofacial surgery. Postoperative pain is not always removable, sometimes it becomes chronic. Pronounced pain syndrome in the postoperative period is experienced by 40 to 75% of patients, but 50% of patients experience pain of medium and high intensity. The aim of this study was a comparative assessment of the effectiveness of a new alternative method of a long-term postoperative regional analgesia and the use of non-narcotic analgesics in patients with tumors of the oral cavity and oropharynx in the postoperative period. The study was conducted in 48 patients (38 men, 10 women, average age 58,05±12,31 years) with tumors of the oral cavity and oropharynx. Patients were divided into two groups depending on the method of postoperative analgesia. In the main group (22 patients) pain was suppressed by a long-term postoperative regional analgesia. In the control group (26 patients) analgesia was performed with non-narcotic analgesics. To control the effectiveness of analgesia, a visual analog scale was used, the duration of analgesia and the manifestation of dysphagia on the day 1, 3 and 10 after surgical intervention as well as similar effects were assessed. On the day 10 of using a long-term postoperative regional analgesia, a positive trend towards a reduction in pain syndrome was observed (2.0±0.63), in contrast to drugs of general action (p

Conclusão: Sua aplicação na pediatria tem sido cada vez mais discutida e mais utilizada corroborando com estudos que têm demonstrado os seus inúmeros benefícios.

Background and purpose: Colonoscopy is a standard method for the diagnosis and treatment of colorectal diseases. The aim of the present study was to compare the analgesic effect of oral oxycodone and intravenous fentanyl in patients undergoing colonoscopy. Materials and methods: This study was conducted as a randomized clinical trial in 80 patients aged 20 to 69 years who were candidates for colonoscopy in two equal groups. Patients in the first group received oral oxycodone and intravenous normal saline, while the second group received oral placebo and 50 micrograms of intravenous fentanyl. 0.5 mg/kg propofol was administered intravenously to both groups. If pain occured, 10 mg propofol was injected. Data on age, gender, vital signs, satisfaction of the endoscopist and pain intensity of the patients were recorded using a numerical rating scale. The data were analyzed using the chi -square test and t-test and SPSS software, with a P˂0.05 value considered significant. Results: The two groups were similar in terms of age (P=0.64) and gender (P=0.055).The mean pain score in the oxycodone group was 3.22±1.78 and in the fentanyl group 2.00±1.43 (P= 0.001). The need for a propofol rescue dose during colonoscopy was higher in the oxycodone group than in the fentanyl group (P= 0.56). There were no significant differences between the two groups in terms of heart rate, respiratory rateand colonoscopist satisfaction (P>0.05). Conclusion: Considering that oral oxycodone has a good analgesic effect compared to intravenous fentanyl, this drug can be used as an analgesic for patients undergoing colonoscopy.

Background: Adequate pain relief during childbirth is a very important issue for women and healthcare providers. This study investigates the effects on maternal and neonatal outcomes of two analgesic methods during labor: water immersion and epidural analgesia. Methods: In this retrospective observational cohort study at a first-level hospital, in Spain, from 2009 to 2019, 1134 women, low-risk singleton and at term pregnancy, were selected. Among them, 567 women used water immersion; 567 women used epidural analgesia for pain control. Maternal outcomes included mode of birth and perineum condition. Neonatal outcomes included 5 min Apgar score, umbilical cord arterial pH, and Neonatal Intensive Care Unit admissions. Chi-square tests and Mann–Whitney U tests, together with their effect sizes (Cramer’s V, odds ratio, and Cohen’s d) were used to test the main hypotheses. Results: Spontaneous vaginal birth was almost 17 times more likely in the water immersion group (OR = 16.866 [6.540, 43.480], p < 0.001), whereas the odds of having a cesarean birth were almost 40 times higher in the epidural group (OR = 39.346 [3.610, 429.120], p < 0.001). The odds of having an intact perineum were more than two times higher for the water immersion group (OR = 2.606 [1.290, 5.250], p = 0.007), whereas having an episiotomy was more than eight times more likely for the epidural group (OR = 8.307 [2.800, 24.610], p < 0.001). Newborns in the water immersion group showed a better 5 min Apgar score and umbilical cord arterial pH and lower rates in admissions at the Neonatal Intensive Care Unit. Conclusions: Women choosing water immersion as an analgesic method were no more likely to experience adverse outcomes and presented better results than women choosing epidural analgesia.

Pain is a major factor expressed by hospital patients and is the main reason they seek medical help. Evidence suggests that children experiencing pain often do not receive optimal pain assessment and relief. This article refers to a literature review discussing tools and management strategies for assessing children's pain. It concludes that implementing an educational program for medical professionals could enhance their awareness of best practices in pain assessment and management guidelines.

Introducción. Tramadol es un analgésico opioide usado frecuentemente para el manejo del dolor crónico no oncológico (DCNO). En Chile, es parte del arsenal farmacológico de los centros de atención primaria para el tratamiento de patologías como artrosis de cadera y rodilla. Es considerado seguro y efectivo, sin embargo, existen reportes de efectos adversos serios por polimorfismos hepáticos, interacciones farmacológicas, intoxicaciones, adicción y muerte. La dosis óptima de tramadol es paciente dependiente. Por esto, es necesario contar con orientaciones específicas para prescribir tramadol de manera segura y eficaz según las características de cada paciente. Materiales y Métodos. Se revisaron guías actualizadas, revisiones sistemáticas y guías de sociedades internacionales sobre el uso de opioides en DCNO y el uso de tramadol en patologías de DCNO como artrosis, lumbago crónico, dolor neuropático y fibromialgia. Resultados. Tramadol no está indicado en el tratamiento de cuadros de dolor primario como fibromialgia y en DCNO secundario es un fármaco de segunda línea o no está recomendado. En dolor crónico neuropático (DCN) es segunda línea de tratamiento. En osteoartritis de cadera, rodilla y mano, se reporta efecto analgésico modesto. Sopesar riesgos versus beneficios en estos pacientes. En artritis reumatoide y lumbago crónico se desaconseja su uso. Conclusiones. Tramadol es un medicamento seguro y efectivo si se indica, administra, supervisa y descontinúa adecuadamente. Sin embargo, puede asociarse a interacciones farmacológicas, efectos secundarios serios, conductas de abuso y usos ilícitos, por lo que es necesario conocer y manejar adecuadamente su farmacología e indicaciones.

Introduction: Ropivacaine is a newer local anaesthetic proven to have a lower systemic toxicity profile, particularly in terms of cardiac and Central Nervous System (CNS) toxicity, than the racemic and levorotatory isomers of bupivacaine, especially in elderly patients. Fentanyl, as an adjuvant, enhances analgesia and promotes early postoperative mobility. Aim: To assess and compare the efficacy and safety of isobaric levobupivacaine and fentanyl versus isobaric ropivacaine and fentanyl in patients undergoing Transurethral Resection of the Prostate (TURP) under Spinal Anaesthesia (SA). Materials and Methods: A randomised clinical study was conducted in the Department of Anaesthesia at SMS Medical College and Attached Hospitals, Jaipur, Rajasthan, India, from March 2021 to January 2023. A total of 60 patients ranging in age from 40 to 80 years, scheduled for elective TURP, were enrolled in the present study. The selected patients were randomly assigned into two groups, each consisting of 30 patients. Group A received a dosage of 2.6 cc of 0.75% isobaric ropivacaine (equivalent to 19.5 mg) along with 0.4 cc of fentanyl (equivalent to 20 micrograms). In contrast, group B received a dosage of 2.6 cc of 0.5% isobaric levobupivacaine (equivalent to 13 mg) and 0.4 cc of fentanyl (20 micrograms). The primary outcome measures were the onset of action, duration of sensory-motor block, and postoperative analgesia. Data were analysed using Epi Info version 7.2.1.0 statistical software. The quantitative data collected were summarised using the mean and Standard Deviation (SD). A p-value of less than or equal to 0.05 was considered statistically significant. Results: The majority of patients in the present study were elderly males in both groups. The mean age distribution in group A was 64.27±8.17, and in group B, it was 65.13±7.1. Both groups were comparable and not statistically significant (p=0.634). The mean weight of the two groups was similar, with group A at 64.9±7.49 kg and group B at 63.1±6.96 kg. Both groups were comparable and not statistically significant (p=0.334). The mean height of the patients was 165±4.85 cm in group A and 164±3.83 cm in group B, and it was comparable between the two groups without statistical significance (p=0.145). The duration of sensory block was 241.03±18.88 minutes in group A and 181.5±33.42 minutes in group B. The duration of motor block was 210.7±17.93 minutes in group A and 160±14.82 minutes in group B. Group A demonstrated a significant prolongation of sensory (p

Introduction: With modern advances, Ultrasonography (USG)- guided regional block techniques have improved nerve blockade with lesser drug usage and maximum safety for patient care. The widely appreciated outpatient surgical care has compelled us to apply the fastest and safest anaesthesia technique. For lower limb surgeries, USG-guided Sciatic Femoral Nerve Block (SFNB) is an emerging alternative to Spinal Anaesthesia (SA). Aim: To compare the safety and efficacy of both techniques in terms of haemodynamic stability, quality of block, and postoperative analgesia. Materials and Methods: A randomised double-blind study conducted at GCS Medical College, Hospital, and Research Centre, Ahmedabad, Gujarat, India, on 80 patients aged 18 to 70 years of either sex, with American Society of Anaesthesiology (ASA) Grade 1 to 3, undergoing below-knee surgeries was divided into two groups. Group A received USA with 1.5 mL hyperbaric inj. ropivacaine 0.75%, and Group B received USGguided SFB with inj. ropivacaine 0.5% 30 mL (15 mL for sciatic nerve and 15 mL for femoral nerve block). Preparation Time (PT), Surgical Anaesthesia Time (SAT), haemodynamic changes, quality of block, Longevity of Anaesthesia (LoA), time of first rescue analgesia, time of spontaneous urination, readiness to discharge, and patient satisfaction were recorded. The statistical analysis was carried out using Statistical Package for Social Sciences version 23.0 (SPSS Inc., Chicago II, USA). The p-value was derived by unpaired t-test and Chi-square test. Results: PT and SAT were higher in Group B (12.10±2.02 mins and 15.74±1.58 mins) than in Group A (6.15±1.12 mins and 8.23±1.45 mins). LoA time and time to first rescue analgesic were higher in Group B (284.10±54.44 mins and 265.71±33.69 mins) than in Group A (138.75±23.30 mins and 132.40±17.41 mins). Time to first spontaneous urination and readiness to discharge were shorter in Group B (136.42±18.40 mins and 158.39±10.78 mins) than in Group A (162.20±26.54 mins and 181.53±18.18 mins). Haemodynamic stability was excellent in both groups with no significant fluctuation. Motor blockade of Bromage 3 grade was achieved in 40 and 38 patients in Group A and B, respectively. The development of VAS score >3 was faster in Group A than in Group B (35 versus 2) at the end of three hours. No adverse events were observed in any patient. Conclusion: USG-guided SFB offers a safe and efficient alternative to Unilateral SA (USA) with satisfactory blockage, stable haemodynamics, and better postoperative analgesia for below-knee surgeries.

Study Design Prospective randomized double-blind study. Purpose To assess the analgesic effects of the combination of a low-dose ketamine and dexmedetomidine (ketodex) infusion and compare it with that of fentanyl for postoperative analgesia after spine surgeries. Overview of Literature Adequate pain management following spine surgeries is crucial. Approximately 57% of patients experience inadequate pain control in the first 24 hours following elective spine surgery, which is attributable to the extensive soft tissue and muscle damage. Methods The study included 60 patients graded American Society of Anesthesiologists I and II and scheduled for thoracolumbar spine surgery involving >3 vertebral levels. The patients were divided into two groups: group KD (ketodex) and group F (fentanyl). The primary objective was to compare the postoperative analgesic requirements among the groups. The secondary objectives included a comparison of the intraoperative anesthetic requirements, postoperative pain scores, hemodynamic parameters, side effects of the study drugs, and the duration of post-anesthesia care unit stay of both the groups. Results Ketodex use prolonged the mean time to first rescue analgesia (22.00±2.30 hours vs. 11.69±3.02 hours, p0.05). The postoperative pain scores were significantly lower in the group KD than in group F at most timepoints (p3 vertebral levels to achieve prolonged analgesia without any opioid-related side effects.

Abstract Objective To evaluate the technical reproducibility of a block of the pericapsular nerve group (PENG) of the hip aided or not by ultrasound in cadavers. Materials and Methods The present is a randomized, descriptive, and comparative anatomical study on 40 hips from 2 cadaver groups. We compared the PENG block technique with the method with no ultrasound guidance. After injecting a methylene blue dye, we verified the dispersion and topographical staining of the anterior hip capsule through dissection. In addition, we evaluated the injection orifice in both techniques. Results In the comparative analysis of the techniques, there were no puncture failures, damage to noble structures in the orifice path, or differences in the results. Only 1 hip from each group (5%) presented inadequate dye dispersion within the anterior capsule, and in 95% of the cases submitted to either technique, there was adequate dye dispersion at the target region. Conclusion Hip PENG block with no ultrasound guidance is feasible, safe, effective, and highly reliable compared to its conventional counterpart. The present is a pioneer study that can help patients with hip pain from various causes in need of relief.

This review aims to provide an overview and update of current literature on the use of intranasal (IN) drug delivery in pediatric emergency medicine (PEM), in terms of the anatomy, physiology, pharmacokinetics, limitations, drug delivery methods, necessary training, safety, contraindications, effectiveness, current indications and trends, and implications for clinical practice and future developments in IN drug administration. We evaluate how IN medication use in PEM has recently evolved, what recent research has revealed about the utility of IN drug delivery in PEM, and what the future of IN drug delivery might look like.
