Background and Aims: Preoperative anxiety can complicate patient outcomes. Music is a noninvasive method to allay anxiety, as revealed in studies. Self-selected (SS) versus prefixed (PF) music had not been studied much. This study was performed to compare SS and PF music in anxiety reduction in patients undergoing elective laparoscopic surgery. Methods: In this prospective study, 90 adults of the American Society of Anesthesiologists grade 1–2, either sex, aged 18–65 years were randomized into three groups, SS, PF music, and control (C), and offered music using headphones 20 min before surgery. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were noted preoperatively (T1), preinduction (T2), 10 min post-induction (T3), 5 min (T4), 1 (T5), and 2 h (T6) postsurgery. The Visual Analog Scale for anxiety (VAS-A) at T1 and T2, VAS-pain and postoperative nausea and vomiting at T5 and T6, and serum cortisol at T1 and T5 were recorded. Results: Group C showed higher VAS-A, HR, SBP, DBP, VAS-pain, and nausea than group-SS and PF (P < 0.05), and higher MAP than group-SS (P < 0.05). The PF group showed higher VAS-A, SBP, DBP, MAP, and VAS-pain than the SS group (P < 0.05). The change in serum cortisol was statistically insignificant. Conclusion: Music (SS > PF) reduces preoperative anxiety, postoperative pain, and nausea–vomiting with better hemodynamic stability.

Interventional endoscopy procedures are challenging for anaesthesiologists due to the various patient, procedural, logistic, and position-related issues. Complex endoscopic procedures like biliary interventions and endoscopic myotomy necessitate longer procedural duration. The mode of anaesthesia is usually deep sedation without any definitive airway device and is frequently associated with hypoxemia events which can be catastrophic. An endotracheal tube, though the gold standard for securing the airway, would prolong the anaesthesia time and delay the recovery. The laryngeal mask airway Gastro™ is a novel supraglottic airway device specifically meant for these procedures as it provides access to the gastrointestinal tract simultaneously with a patent airway. Though its purported advantages are undoubted, its clinical usage has various pitfalls that can hinder its wider acceptance and practical utility, especially when newly introduced. The literature is limited on the feasibility of this device in both the ease of endoscopy and the prevention of hypoxemia. In this review, we have discussed the device’s properties, its varied use cases, the supporting evidence for the same, the caveats, and the future perspectives.

Background Conventional fascial plane block approaches for upper abdominal surgeries spare the lateral cutaneous nerve. An external oblique intercostal block (EOIB) may be suitable for upper abdominal incisions as it blocks the lateral and anterior branches of the intercostal nerves T6–T10. However, there is a paucity of studies evaluating this block in clinical settings. The study aimed to compare the analgesic efficacy of combined EOIB and rectus sheath block with local infiltration analgesia (LIA) in laparoscopic cholecystectomy (LC). Methods After obtaining written informed consent, 70 patients were randomly allocated to undergo right-sided EOIB with 20 ml and left-sided RSB with 10 ml of 0.25% bupivacaine at the end of surgery (group ER, n = 35). Patients in the LIA group (n = 35) underwent local infiltration at the port site using 20 ml of the same solution (group LIA, n=35). Results The visual analog scale scores with combined EOI and RSB were significantly lower than those with LIA at 1, 2, 4, 8, and 12 h (P < 0.001). Rescue analgesics were required by 65.7% and 14.3% of the patients in the LIA and block groups, respectively (P < 0.001). The time to first rescue analgesic was significantly greater in the ER group than that in the LIA group (2.8 ± 1.10 vs. 1.6 ± 0.50 h; P = 0.012). The number of times rescue analgesia was required was significantly lower in the ER group than that in the LIA group (1.00 ± 0.00 vs. 1.83 ± 0.72; P = 0.015). Nausea and vomiting scores were higher in the LIA group than those in the ER group (P < 0.001). Patient satisfaction scores were higher in the ER group than those in the LIA group. Conclusions EOIB combined with RSB provides superior analgesia compared with LIA and should be considered for LC.

Though permanent vocal cord palsy consequent to recurrent laryngeal nerve (RLN) injury is rare following thyroidectomies, its consequences are grave enough for it to be the most feared complication postoperatively. Anesthesiologists and surgeons take various precautions to prevent its occurrence and employ various methods for its early detection. They include direct visualization of the nerve intraoperatively, use of intraoperative nerve monitoring, and post-extubation visualization of vocal cord mobility by use of direct or indirect methods. In the present narrative review, we aim to discuss the clinical evidence pertaining to the various methods adopted for the prevention and early detection of RLN palsy during thyroidectomy.

Background Patients who undergo spine surgery often experience severe pain postoperatively. Multimodal analgesia inclusive of a regional block provides optimal pain relief. Thoracolumbar interfascial plane (TLIP) block may provide promising analgesia in these patients.

Background and Aims: Videolaryngoscopes have an undisputed role in difficult airway management, but their role in routine intubation scenarios remains underappreciated. McGrath MAC is a lightweight laryngoscope with a disposable blade. It remains to be proven if it performs as efficiently as the reusable videolaryngoscopes like C-MAC and whether it has an advantage over standard Macintosh laryngoscope in predicted normal airways. Material and Methods: We recruited 180 adult patients and randomly divided them into three groups for intubation with either Macintosh laryngoscope (Group-A), C-MAC (Group-B), and McGrath (Group-C). The primary objective was to compare the first attempt success rate. Secondary objectives included Cormack-Lehane (CL) grades, laryngoscopy time, intubation time, ease of intubation, need for optimization manoeuver, and the number of passes to place the endotracheal tube. Results: The two videolaryngoscopes provided a superior first attempt success rate as compared to Macintosh laryngoscope (P = 0.027). The CL grade-I was 100% in group B, 41.7% in group-A and 90% in group-C (B vs C; P = 0.037). Laryngoscopy time was 9.9 ± 2.5 s, 12.6 ± 0.8 s, and 13.1 ± 0.8 s for groups A, B, and C, respectively (B vs C; P = 0.001). Intubation time was 24.4 ± 12 s, 28.3 ± 1.9 s, and 37.3 ± 5.8 s for groups A, B, and C, respectively (P < 0.0001). The number of tube passes was highest in group C. Conclusion: Videolaryngoscopes provided a superior glottic view and resulted in a superior first attempt success rate as compared to Macintosh laryngoscope. When comparing the two videolaryngoscopes, C-MAC resulted in better intubation characteristics (shorter intubation time, better glottic views, and higher first-attempt success rates) and should be preferred over McGrath for intubation in adult patients with normal airways.

Caffeine has a multitude of uses in anaesthesia, and numerous studies have evaluated its efficacy and usefulness in various aspects of anaesthesia and medical practice. Its various applications in anaesthesia include its role in awakening from anaesthesia, managing post-dural puncture headache, managing post-sedation paradoxical hyper-activity in children, post-operative bowel paralysis, and apnoea in paediatric populations, that is, apnoea in infancy, paediatric obstructive apnoea, and post-anaesthetic apnoea in pre-mature infants. Though the effects of caffeine on bronchial smooth muscle, neurological, and cardio-vascular systems are well known, the relatively little-known effects on the endocrine and gastro-intestinal (GI) system have been recently taking primacy for eliciting its therapeutic benefits. The literature shows encouraging evidence in favour of caffeine, but unambiguous evidence of caffeine benefits for patients is lacking and needs further investigation. In this narrative review of literature, we summarise the available literature to provide insights into the pharmacokinetics, pharmacodynamics, clinical application of caffeine in modern anaesthetic practice, and evidence available in this field to date. An awareness of the various physiological effects, adverse effects, reported applications, and their evidence will widen the horizon for anaesthesiologists to increase its rational use and advance research in this field. Well-designed randomised controlled trials regarding the various outcomes related to caffeine use in anaesthesia should be planned to generate sound evidence and formulate recommendations to guide clinicians.

Abstract Background Quadratus lumborum block has been claimed to provide effective analgesia in abdominal surgeries by covering both somatic as well as visceral pain. However, its utility in morbidly obese patients has not been reported or evaluated. Case presentation In this case report, of laparoscopic hernia repair in a morbidly obese patient (weight 110 kg, height 1.53 m, BMI 46.9 kg/m2), there was excellent perioperative analgesia with no rescue opioid consumption in intraoperative period and average VAS score of 3 in 24 h postoperatively. The first recue analgesic was administered in the form of intravenous (IV) diclofenac 75 mg (diluted in 100 ml normal saline) 12 h after surgery when the patient reported a VAS of 5. Conclusions QL block is an effective, feasible, and safe option for providing analgesia for laparoscopic hernia repair in morbidly obese patients.

Monkeypox is a contagious disease that manifests as a smallpox-like skin rash. The disease has shown a sudden surge worldwide across several countries. These patients may present for emergency surgery. Anesthetic management of these cases in an emergency setting is challenging. There is not much literature on the anesthetic management of monkeypox patients. We aimed to discuss the anesthetic management of monkeypox in this review.

Background Nasotracheal intubation (NTI) is commonly performed in oromaxillofacial surgeries. We did this meta-analysis to ascertain whether use of video laryngoscopy (VL) provided better NTI characteristics as compared to direct laryngoscopy (DL) in patients undergoing oromaxillofacial surgeries. Methods We performed a systematic search to identify randomized controlled trials comparing VL with DL for NTI in adults undergoing elective oromaxillofacial surgery. The primary outcome was time to intubation. Secondary outcomes included the first attempt success, overall success, incidence of nasal bleeding, Cormack and Lehane grade, and maneuvers required. Results Of the 456 studies identified following a systematic search, 10 were included. Meta-analysis showed a significantly lower time to tracheal intubation favoring VL (mean difference: –9.04, 95% CI [–12.71, –5.36], P < 0.001; I2 = 59%). VL was also associated with a greater first attempt success (relative risk [RR]: 1.10, 95% CI [1.04, 1.16], P = 0.001). Maneuvers to facilitate intubation were less with VL (RR: 0.22, 95% CI [0.10, 0.51], P < 0.001). There was no difference in overall intubation success (RR: 1.04, 95% CI [0.98, 1.10], P = 0.17). The incidence of bleeding did not differ between the DL and VL groups (RR: 0.59, 95% CI [0.32, 1.08], P = 0.09). Conclusions Evidence as per this meta-analysis suggests VL leads to a shorter time to NTI, a greater first attempt success rate, and reduced need for maneuvers when compared to DL. The present study supports use of VL as a first line device for NTI in oral-maxillofacial surgeries in experienced hands.

In the past, management of pain in neonates was regarded as unnecessary, with the belief that neonates have an immature nervous system and do not perceive pain. Later studies confirmed that neonates certainly do feel pain, though they lack the inhibitory mechanisms that modulate excruciating stimuli, unlike in older children. Repeated painful encounters experienced in the newborn period are associated with poor cognitive and motor development by 1 year of age. Pain in preverbal infants and children is also poorly recognized and often undertreated. Neonates and preverbal children cannot verbally communicate their pain and discomfort but express them through specific behavioral, physiological, and biochemical responses. Several pain measurement tools have been developed for young children as surrogate measures of pain. To achieve optimum postoperative or procedural pain relief, easily understandable tools and a multimodal treatment module should be tailor-made for each health-care facility that cares for neonates and young infants. The aim of this advisory is to outline key concepts of pain assessment in neonates and preverbal children and suggest a rational approach to its management by all anesthesiologists, pediatricians, nursing staff, and other medical personnel caring for these children. The Indian Association of Paediatric Anaesthesia (IAPA) convened an online meeting in April 2020 to formulate the advisory on pain management in neonates and preverbal children under the chairmanship of Dr. Elsa Varghese, President IAPA, and members of the guideline committee. After several such meetings and revisions using feedback from IAPA members, the final guidelines were released in October 2020 on the IAPA website. Recommendations: Pain relief should generally be accomplished with a combination of nonpharmacologic approaches and pharmacologic techniques in a stepwise tiered manner by escalating type and dose of analgesia with anticipated increases in procedural pain. Nonpharmacological distraction measures may be sufficient for minor needle procedures like vaccination and venipuncture and may be offered as a first step and to complement other pain management remedies. An interdisciplinary approach involving pharmacologic, cognitive-behavioral, psychologic, and physical treatments should be employed whenever feasible.

Introduction: the use of cuffed endotracheal tubes (ETTs) in children is debatable. Despite recent literature on the use of cuffed ETT in children, its use is relatively low even in developed world. We conducted this survey to explore the perceptions and patterns of cuffed/uncuffed ETT usage in children,

Direct laryngoscopy has remained the sole method for securing airway ever since the inception of endotracheal intubation. The recent introduction of video-laryngoscopes has brought a paradigm shift in the pratice of airway management. It is claimed that they improve the glottic view and first pass success rates in adult population. The airway management in children is more challenging than adults. The role of videolaryngoscopy for routine intubation in children is not clearly proven. This review attempts to discuss various videolaryngosocpes available for use in pediatric patients.

Background and Aims: We describe the epidemiological and clinical characteristics, and 28 day outcome of critically ill COVID-19 patients admitted to a tertiary care centre in India. Material and Methods: We included 60 adult critically ill COVID-19 patients in this prospective observational study, admitted to the intensive care unit (ICU) after obtaining ethics committee approval and informed consent. Demographics, clinical data, and treatment outcome at 28 days were assessed. Results: Demographic characteristics of the COVID-19 patients reveal that compared to the survivors, the non-survivors were significantly older [57.5 vs. 47.5 years], had more comorbid disease [Charlson's comorbidity index 4 vs. 2], higher Apache II scores [19 vs. 8.5], and had significantly higher percentage of smokers. Diabetes mellitus and hypertension were the most common comorbidities. Dyspnea, fever, and cough were the most common presenting symptoms. Total leucocyte count as well as blood lactate level were significantly higher in non-survivors. Around 47% patients had severe ARDS, and 60% patients required invasive mechanical ventilation. 28 day ICU mortality was 50%, with a mortality of 75% in patients receiving invasive mechanical ventilation. Mortality was higher in males than females (57% vs. 33%). Acute kidney injury and septic shock were the most common non-pulmonary complications during ICU stay. Incidence of liver dysfunction, septic shock, and vasopressor use was significantly higher in the non-survivors. Conclusion: This study demonstrates a high 28 day mortality in severe COVID-19 patients. Further well designed prospective studies with larger sample size are needed to identify the risk factors associated with poor outcome in such patients.

The COVID-19 is an ongoing global crisis. To deal with it efficiently, health-care system has to gear up to the increasing burden by judicious use of workforce and resources. In the perioperative setting, adequate preventive measures are of prime importance to prevent infection spread among health-care workers. The knowledge regarding the disease is still evolving. In this article, we have outlined the basic epidemiology, pathology, presentation, and diagnosis of COVID-19 along with the considerations for operating room preparedness, personal protective equipment required, airway management, anesthesia conduct, and perioperative concerns when managing positive or suspected COVID-19 pediatric patients and have suggested ways to overcome potential hindrances based on available literature. We have also deliberated upon the specific considerations for a COVID child undergoing regional anesthesia and critically ill COVID-19 pediatric patients. Careful adaptation of working principles based on local needs can help in the prevention of disease spread when optimizing care to the patients.

Background and Aims: Arthroscopic orthopaedic surgery may lead to significant postoperative pain. Interscalene block (ISB) is associated with undesirable effects like phrenic nerve palsy. Shoulder block (ShB) is a relatively recent diaphragm sparing alternative for analgesia in these cases. Methods: This prospective randomised trial was conducted in 70 adult patients posted for arthroscopic Bankart repair surgery. Patients were randomly assigned into two groups: interscalene block [Group ISB (n = 35): 0.5% bupivacaine 10 ml] or shoulder block [Group ShB (n = 35): 0.5% bupivacaine (suprascapular block 10 ml and axillary block 10 ml)] using ultrasound and nerve stimulator. The primary aim of our study was to compare the ISB with ShB for visual analogue score (VAS) in recovery area (zero hour). Time for block performance, VAS, time to first rescue analgesia, total analgesic requirement, patient satisfaction and complications were recorded. Results: VAS was significantly higher in ShB group at 2 and 4 h (P = 0.001 and 0.000) while it was significantly higher in ISB group at 12 h (P = 0.013). The time to first analgesic request was significantly prolonged in ISB group as compared to ShB group (8.22 h vs. 4.69 h; P = 0.002) but total analgesic requirement and patient satisfaction at 24 h were similar. Complications like dyspnoea, ptosis and motor weakness were seen only with ISB group. Conclusion: Both ShB and ISB blocks have similar efficacy in terms of postoperative pain scores, cumulative analgesic requirements and patient satisfaction. However, considering the various undesirable effects associated with ISB, like phrenic nerve blockade, prolonged upper limb weakness and the occurrence of rebound pain, shoulder block may be preferred for arthroscopic shoulder surgeries.

Airway emergencies are among the life-threatening events that are encountered in the operating room, emergency department or intensive care unit. They are important causes of preventable morbidity and mortality where time is the essence. It can be extremely challenging to rapidly assess the airway for early diagnosis and perform appropriate interventions simultaneously. Outcome depends on the implementation of an optimal strategy to establish a patent airway. Equally important is the overall stabilisation of the patient and management of the primary clinical condition as appropriate. Key components of management include early recognition of threatened airway, appropriate and timely airway intervention, and maintaining oxygenation. In this review, we describe aetiology, evaluation and management of airway emergencies.

During the past two decades, a vast number of studies done on rodents and nonhuman primates have implicated general anesthetic exposure of developing brains in producing neurotoxicity leading to various structural and functional neurological abnormalities with cognitive and behavioral deficits later in life. However, it is still unclear whether these findings translate to children and whether single exposure to anesthesia in childhood can have long-term neuro-developmental risks. Considering the fact that a large number of healthy young children are undergoing elective surgery under general anesthesia globally, any such potential neurocognitive risk of pediatric anesthesia is a serious public health issue and is therefore important to understand. This review aims to assess the current preclinical and clinical evidence related to anesthetic neurotoxicity.

Erector spinae plane block has been described to manage post-thoracotomy pain. It is a simple block and shown to be provide effective analgesia. In single shot blocks opioid supplementation may be required to manage pain after the effect of local anesthetic wears off. In this case, we describe a case of chest wall tumor excision in a child who received clonidine in addition to local anesthetic for the erector spinae plane block. This provided long lasting and effective postoperative analgesia and may be considered to prolong the analgesia achieved with erector spinae plane block.
