Despite the well-known benefits of spinal anesthesia (SA), this technique remains underutilized among pediatric anesthesiologists. According to the data from the Pediatric Regional Anesthesia Network, SA accounted for less than 5% of all neuraxial techniques. Some of the factors for underutilization of SA include: Limited duration, unfamiliarity with the technique in younger children, and surgeon preference for general anesthesia. The safe and successful use of SA in children involves recognition of anatomical and physiological differences between adults and children owing to differences in bony structures, spinal cord growth and cerebrospinal fluid physiology. Reports on successful use of SA in children for various surgeries have increased. This educational review summarizes what is known about SA in children, reviews the literature from the last decade and provides suggestions for development of SA in children. Technical considerations, role of ultrasound, guidance on dosing, physiological effects, unexplained aspects of the mechanism of action and combined caudal/SA are discussed. [ABSTRACT FROM AUTHOR]

During the preanesthetic assessment of the obstetric patient, it is critical to assess the patient's cardiovascular baseline condition, identify any potential risks, and facilitate behavioral modification to develop an individualized management strategy aimed at minimizing complications. Cardiac point-ofcare ultrasound (POCUS) is a valuable instrument for assessing the morphology and function of the heart prior to surgery. Cardiac POCUS is not designed to replace comprehensive transthoracic echocardiography, which is the realm of cardiovascular anesthesiology and cardiology. However, when used in conjunction with anamnesis, physical examination, electrocardiogram, and previous laboratory results, cardiac POCUS is a valuable adjunct in the diagnostic toolbox of anesthesiologists. It allows for direct visualization of the heart and great vessels, with added benefits of speed, availability, and low risk for the patient. The purpose of this manuscript is to explore and describe the advantages of cardiac POCUS in the preanesthetic period of obstetric patients and its potential value for anesthesiologists through the identification of potentially hazardous conditions that may require individualized preoperative management.

The incorporation of new technologies such as ultrasound, J-Plasma (helium plasma) and MicroAire (power assited liposuction) has facilitated liposculpture procedures, resulting in greater patient satisfaction. The benefits of these technologies are accompanied by low reported complications; this case is the fourth description of pneumomediastinum secondary to the use of Renuvion® (J-Plasma) after liposuction for fat removal in the arms and thighs. This rare complication should be considered as part of the differential diagnosis during the study of clinical dyspnea and subcutaneous emphysema in the postoperative period. [ABSTRACT FROM AUTHOR]

Introduction: Although the subclavian vein offers significant advantages over other approaches for ultrasound-guided central venous access, it is not the first choice in the pediatric population, mainly due to its proximity to the pleura and the subclavian artery. Objective: To assess the sonoanatomical characteristics of the subclavian vein and adjacent structures using the supraclavicular approach in a pediatric population. Materials and methods: Observational, intraoperative, cross-sectional study, between June 2021 and March 2022. The population consisted of ASA I, II and III children taken to non-emergent surgical procedures under general anesthesia. Images were acquired with the patients under general anesthesia, using a high-frequency linear probe to identify the subclavian vein and measure the anatomical landmarks. Results: A total of 67 children were recruited; mean age was 6 years (IQR: 2-12 years), with male sex predominance (61%). Median weight was 22 kg (IQR: 12.2-34 Kg) and median height was 115 cm (IQR: 88-142 cm). Measurements in relation to the vessel showed a mean distance from the skin of 0.70 cm (SD: 0.18 cm), while mean distance from the skin to the pleura was 1.31 cm (SD: 0.28 cm). Mean vein diameter was 0.49 cm (IQR: 0.40-0.63 cm). The mean hypothetical approach angle to the vessel was 22.09 degrees (SD: 4.37 degrees), while the approach angle to the pleura was 39 degrees (SD: 5.31 degrees). No concurrent visualization of the vein and artery was documented in any of the recorded sonoanatomy windows. The tests pointed to an average difference of 0.61 cm in vessel depth in relation to the pleura, and the angle of approach to the vessel was 16.91 degrees smaller when compared with the angle of approach to the pleura (p < 0.001). Conclusions: Using this technique, the supraclavicular approach to the subclavian vein in children is safe and feasible, with an average skin-to-vessel distance of 0.70 cm, minimizing the risk of pleural puncture. Additional studies are required to optimize this technique in the pediatric population. [ABSTRACT FROM AUTHOR]

Introduction: Spinal anesthesia requires palpation of surfaces in order to identify the intervertebral spaces in the lumbar spine. In elderly individuals, the procedure is more challenging due to age-related degenerative changes in the spine. Objective: To determine which technique between ultrasound (US) guidance or the use of anatomical landmarks to guide spinal anesthesia ensures a higher success rate in elderly patients. Methods: Prospective observational cohort study in patients with an indication to receive subarachnoid anesthesia, regardless of the type of surgical intervention, carried out at Hospital Universitario del Valle and Fundación Hospital San José Buga. Data were collected over a 12-month period at the time of making the puncture. The treating anesthetists were free to choose between US guidance or the use of anatomical landmarks. Results: Overall, 80 patients were assessed, including men and women over 65 years of age (mean 78.50±9.04). The number of punctures as well as needle redirections were significantly lower in the US-guided group. Additionally, in the group in which anatomical landmarks were used to guide the puncture, the marked site did not coincide with the actual puncture site confirmed with US in 37.5% of cases (p<0.001). This could result in inadequate block or complications associated with intradural puncture. Conclusions: US-guided neuroaxial anesthesia in elderly individuals could facilitate success on the first attempt. [ABSTRACT FROM AUTHOR]

RESUMO Introdução: A matriz de competências dos programas de residência médica em anestesiologia do Brasil apresenta como objetivo específico “realizar a anestesia com segurança em todas as suas etapas”, cujos elementos para a implementação de um currículo específico precisam ser definidos. Diante desse cenário, foram propostas a elaboração e a implementação de um módulo educacional sobre segurança do paciente para residentes de anestesiologia. Objetivo: Este estudo teve como objetivos desenvolver e implementar um módulo educacional sobre segurança do paciente em anestesiologia para residentes da especialidade, e avaliar a efetividade e o grau de satisfação deles com o módulo. Método: Trata-se de um estudo quase experimental com desenho série temporal interrompida com um grupo, realizado no âmbito do mestrado profissional em Ensino na Saúde, de uma universidade pública do Nordeste do Brasil, com residentes de anestesiologia dos três anos. Desenvolveu-se um módulo educacional, em formato e-book, e implementou-se uma estratégia pedagógica para intermediar a aprendizagem de residentes, em quatro encontros presenciais, ocorridos durante o expediente de atividades práticas no hospital. Realizaram-se uma avaliação de conhecimentos com pré-teste, antes da primeira discussão dos conteúdos de segurança do paciente, no primeiro encontro, e pós-teste, no último encontro, e uma avaliação de satisfação utilizando questionário com escala Likert. Resultado: As notas do pré-teste variaram de 6.25 a 8.75 (média 7.50), enquanto no pós-teste houve uma variação de 7.50 a 10.0 (média 9.03). Houve melhora significativa das notas medianas no pós-teste de 7.50 para 8.75, com p = 0.0199. O questionário de satisfação (coeficiente alfa de Cronbach = 0.793) apresentou respostas satisfatórias para cada um dos itens avaliados, todas variando de “concordo” a “concordo totalmente”. Conclusão: A elaboração e implementação de um módulo educacional para intermediar a aprendizagem durante o processo formativo de residentes de anestesiologia foram efetivas em promover conhecimento sobre segurança do paciente para o anestesiologista em formação, com altos índices de satisfação. Assim, ressalta-se a importância da inserção do tema segurança do paciente na estrutura curricular dos cursos de residência em anestesiologia, com espaço e tempo protegidos para o processo de aprendizagem desses profissionais. Ademais, são necessários mais estudos que possam mensurar o impacto dessa intervenção em longo prazo, sua influência na aquisição de competências e se essas intervenções educacionais melhoram os resultados para os pacientes.

La evaluación precisa de la vía aérea difícil (VAD) es crucial en anestesiología. La inteligencia artificial (IA) emerge como una herramienta prometedora, pero su eficacia en la predicción de VAD aún no está clara. El objetivo de este estudio fue demostrar la eficacia del sistema de inteligencia artificial para la predicción de vía aérea difícil. Se realiz´ó un estudio observacional comparativo, prospectivo, de corte transversal. Se evaluaron 50 pacientes mediante fotografías estandarizadas analizadas por IA y evaluación de vía aérea (VA) convencional por anestesiólogos. El método de IA identificó una incidencia de VAD del 16%, mientras que el método convencional detectó un 38%. La IA mostró una sensibilidad del 42%, especificidad del 94%, valor predictivo positivo del 80% y negativo del 73%. El área bajo la curva ROC fue 0.6782683 para IA y 1 para el método convencional. Aunque la IA demostró alta especificidad, su sensibilidad moderada sugiere limitaciones en la predicción de VAD. El método convencional mostró un rendimiento superior. La IA tiene potencial como herramienta complementaria en la predicción de VAD, pero actualmente no puede reemplazar la evaluación clínica convencional.

Postoperative pain management in hip surgery is classified as severe and its inadequate control leads to complications that increase patient morbidity and mortality. The PENG block is advocated as a safe, opioid-sparing analgesic technique, which provides an adequate level of analgesia. The purpose of this study is to analyze about the efficacy, safety and therapeutic appropriateness of the PENG block in hip surgery. To this end, a narrative review is conducted using various databases such as PubMed and the Cochrane library. In all of the studies analyzed, an adequate postoperative pain control was achieved using the PENG block, with reduction in pain assessment scales and opioid consumption in the first postoperative hours. Improved results were also seen as compared with other regional blocks. There were few adverse effects and none of them was classified as severe. The PENG block contributes with numerous advantages and few adverse effects for hip surgery. Further studies are needed on this block, whether alone or in combination with other regional techniques, so as to include it in analgesia protocols, developing a standardized approach and study the outcomes in more controlled settings.

Surgery is a key pillar in medical care, and both the surgical as well as the anesthetic components are essential within the health systems in countries of all levels of development. Every year, close to 230 million surgical procedures are performed worldwide, with pediatric surgery being representative, as around 85% of children require a surgical procedure. However, the issue of education and training of the people involved in pediatric surgery who can provide safe surgical and anesthetic care in medium and low income countries has been absent from the global health debate. The development of anesthesia in pediatrics faces many challenges: it is a relatively new specialty, it has to deal with clinical challenges associated with anatomical, physiological, psychological and procedure-related differences, while it faces the reality of few training opportunities which results in a limited number of duly trained and qualified specialists in pediatric anesthesiology. In Latin America, the possibility of applying to a specialization in pediatric anesthesia is limited. In particular in Colombia it has not been possible to establish a pediatric anesthesia subspecialty, creating the need to promote formal and informal training in this discipline in order to ensure that safe, good quality anesthetic care is provided to children. This article describes the development of pediatric anesthesia training in the world and in Colombia, highlighting the relationship between the incidence of anesthetic complications and the need for training in this discipline.

Introduction: Low-dose ketamine infusions have shown analgesic effectiveness for the management of postoperative pain. The impact of low-dose ketamine infusions on cardiovascular response is dose-dependent and requires a better knowledge about its effects on this population. Objective: To conduct a systematic review to describe changes in systolic, diastolic and mean arterial pressure, and heart rate 24, 48 and 72 hours after surgery. Methods: Randomized, controlled trials were reviewed in the Cochrane Library, PubMed, EMBASE, SciELO, Lilacs and grey literature on low-dose ketamine infusions for the study variables. The quality of the studies was assessed using the Cochrane's risk of bias tool. Results: Six randomized, controlled trials with 641 patients were included. Low-quality evidence was found suggestive of a lack of certainty of any significant differences in the systolic blood pressure variables at 24 hours (mean standard deviation -1.00, 95 % CI: -7.27 to 5.27). A statistically significant higher mean heart rate at 24 hours was identified in the low-dose ketamine infusion group, (mean standard deviation 1.64 95 % CI: 0.38 to 2.90) which did not reach clinical significance. A lower pain level and less use of opioids was identified in the low-dose ketamine infusion group. Conclusions: Low quality evidence was found, suggesting that low-dose ketamine infusions are not associated with significant changes in blood pressure or heart rate 24 -- 48 hours after surgery. It is important to individualize cardiovascular risk for each case, before initiating treatment. [ABSTRACT FROM AUTHOR]

Postoperative acute kidney injury is an underdiagnosed condition. Its incidence is variable and depends on demographic, clinical, and surgical stress-associated factors; hence the pathophysiology is multifactorial. It is extremely important to acknowledge those risk factors early and use tools to estimate the risk of developing the condition, in order to adopt perioperative measures to mitigate its occurrence and impact. Some of the complications resulting from this condition include prolonged ICU stay, higher susceptibility for infections, hospitalization-related complications, progression to acute and chronic kidney failure, and even the need for transient or permanent renal replacement therapies (RRT) in addition to diseases that increase the cardiovascular risk, such as systemic high blood pressure and/or coronary heart disease that result in increased comorbidities and mortality, with subsequent increases in healthcare costs, lower quality of life and increased burden of the disease in the short and long term. A systematic search of the literature was conducted in PubMed, Google Schoolar, and Lilacs, under the terms MeSh and DeCs using Boolean operators; a review was conducted of the summary of the articles identified and 57 of them were selected for their comprehensive reading. This narrative review summarizes the relevant information on this pathology for prevention and identification purposes, for the adequate management of patients undergoing major non-cardiac surgery.

Se emplearon procesamientos matemáticos, tablas y gráficos. Resultados: se diseñó un sistema didáctico de educación ciudadana para la formación académica de los residentes en Anestesiología y Reanimación que ofreció una nueva visión a su formación académica al proponer, desde la semipresencialidad y el empleo de las tecnologías de la información y las comunicaciones, diferentes formas de organizar la superación en el cuarto nivel de la enseñanza. Conclusiones: el sistema diseñado fue valorado como adecuado para su aplicación por los especialistas, los que tuvieron en cuenta su actualidad, originalidad, pertinencia, coherencia y valor científico; además realizaron sugerencias para su perfeccionamiento.

Virginia Apgar (1909-1974) fue una importante médica estadounidense mundialmente famosa por haber diseñado la escala que lleva su nombre y que se utiliza para evaluar neonatos que nacen en cualquier lugar del planeta donde se realice medicina moderna. Además de su trabajo como anestesióloga, docente e investigadora tenía una serie de aficiones muy variadas: lectura, basquetbol, pesca, golf, filatelia y, sobre todo, música. Interpretó el violín y el chelo y tocó en varios grupos de cámara. Motivada por una de sus pacientes, Carleen Hutchinson, maestra de ciencias y música, construyó cuatro instrumentos: viola, violín, cello y mezzo violín, que posteriormente ella misma interpretaría. Cerca de veinte años después de su fallecimiento, el 24 de octubre de 1994, en Dallas, durante la reunión anual de la Academia Americana de Pediatría y el lanzamiento de una estampilla del Servicio Postal Americano conmemorativa en su honor, fueron interpretadas varias de las piezas favoritas de la doctora Apgar con los instrumentos que ella misma elaboró. La admirable vida de Virginia Apgar mezcló actividades diversas y dejó un legado de un valor incalculable para la humanidad.

The present case report aim to detail the surgical removal of a sharp foreign body of metallic origin, adhered to the inner wall of the gastric ventricle, in a specimen of Caracara plancus. The chosen surgical procedure was gastric ventriculotomy, although this is not the approach of choice since this organ has a thick muscular wall. Once adhered to the gastrointestinal tract, with most of its portion in the gastric ventricle, other accesses to the foreign body were discarded. The anesthetic approach was weighted for the species, with pre-anesthetic medication with 1 mg kg-1 butorphanol, 15 mg kg-1 esketamine and 1 mg kg-1 midazolam, intramuscularly, while anesthetic induction and maintenance was performed using sevoflurane. Monitoration was mainly performed by capnography and vascular Doppler. In the postoperative period, antibiotic therapy was instituted with 5 mg kg-1 enrofloxacin, as well as analgesic control with 0.2 mg kg-1 meloxicam and 25 mg kg-1 dipyrone, intramuscularly, at an appropriate dosage for the species. Without intercurrences, the surgical procedure performed and the pre, intra and post-surgical protocols instituted were considered efficient, since they culminated in the animal's recovery with regard to the ingestion of the metallic foreign body and its triggered gastrointestinal dysfunctions.

During the past two decades, the videolaryngoscope (VDL) has become a valuable and effective tool for the management of the airway, not just in the realm of anesthesiology, but also in other medical specialties in clinical scenarios requiring tracheal intubation. In countries such as the United States, this represents over 15 million cases in the operating room and 650,000 outside the OR. The overall accumulated incidence of difficult airway is 6.8% events in routine practice and between 0.1 and 0.3 % of failed intubations, both associated with complications such as desaturation, airway injury, hemodynamic instability and death. Notwithstanding the fact that the VDL has proven advantages such as improved visualization of the glottis, higher first attempt success rates, and a shortened learning curve, most of the time its use is limited to rescue attempts or as a secondary option. The aim of this article is to comment the advantages and limitations of the VDL vs. the direct laryngoscope in a wide range of clinical settings, including the operating room, intensive care units, emergency departments, pediatrics, obstetrics, and Covid-19 to consider its routine use.

Introduction: The minimum number of procedures required to be performed during anesthesia training has not been officially defined in Colombia. Although a number is no guarantee of acquired competencies, it does indicate the level of opportunity offered by the different programs. This study describes the practical training afforded to residents in a graduate anesthesia program in Colombia, and compares its results with international standards. Objective: Describe exposure to procedures performed by residents enrolled in a three-year anesthesia specialization program in Colombia between 2015 and 2020, and compare with the standards proposed by ASCOFAME and ACGME. Methods: Descriptive, cross-sectional study which included residents who did their specialization in a Colombian anesthesia program between 2015 and 2020. Complexity, anesthesia techniques, invasive monitoring and airway approach were described. Finally a descriptive comparison was made with the published references of the Colombian Association of Medical Schools (ASCOFAME) and the Accreditation Council for Graduate Medical Education (ACGME). Results: The results for 10 residents were included. Each resident had a median of 978 cases (IQR 942-1120), corresponding to 25 surgical specialties, the most frequent being general surgery (18%), orthopedics (16%), pediatric surgery (19%), and obstetrics (10.8%). According to the American Society of Anesthesiology (ASA) classification, the majority of patients were ASA II (39.63%) and ASA III (28.4%). Adequate exposure was achieved in 11 of the 15 categories proposed by ACGME and in 6 of the 15 proposed by ASCOFAME. Conclusions: A detailed description of the practice component acquired by the residents during their three years of training was obtained. This baseline provides insight into the national landscape and allows to describe the relationship with international standards. [ABSTRACT FROM AUTHOR]

After 70 years of the formalization of medical specialties in Colombia, very little progress has been made in the educational models for the acquisition of clinical competencies in these postgraduate programs. Furthermore, although there is already a law on human resources in health, the Colombian medical education system lacks specific regulations on the training of health professionals (physicians) in the different medical specialty programs offered in the country. Likewise, at present, factors such as the financial crisis of public hospitals, the limited number of accredited hospitals and the growing number of medical schools and specialization programs, affect the comprehensive and equal development of medical competencies of professionals who are trained as specialists in the different postgraduate medical programs offered in Colombia. In view of the above, the purpose of this article is to present a proposal for postgraduate medical education that prioritizes the adequate acquisition of competencies over compliance with the time required to complete the curricula of the different medical specialties. However, this involves several prerequisites: a regulatory body in charge of overseeing and monitoring the training of medical residents or specialists in the country; strong training in university teaching for professors practicing in medical schools and university hospitals; the standardization of the graduates profile; adequate financing of university hospitals, as well as appropriate support in the process of accreditation as such, and the self-evaluation and continuous improvement of postgraduate medical programs.

Introduction Anesthetists play an important role during interventional radiology procedures. Like the main operator, anesthetists may also be subject to significant radiation levels in the fluoroscopy suite. Due to its complexity, hepatic chemoembolization procedures demand high fluoroscopic times and digital subtraction angiography images, exposing patients and medical staff to high radiation doses. Objective To assess and quantify the radiation to which one anesthetist was exposed over the course of seven consecutive hepatic chemoembolization procedures, and compare it to the exposure received by the main operator. Methods Medical staff dosimetry was evaluated during seven consecutive hepatic chemoembolization procedures conducted in a private hospital in Recife (Brazil), using thermoluminiscent dosimeters placed in regions of the head and torso. Results For the seven procedures evaluated in this study, the anesthetist received, on average, absorbed doses to the glabella, left eyebrow, right eyebrow and effective dose of 142.4 ± 72 µSv, 117.3 ± 66 µSv, 137.8 ± 71 µSv and 12.4 ± 8.4 µSv, respectively. Conclusions In some cases, ocular dose and effective dose received by the anesthetist may be 4 and 4.7 times greater, respectively, when compared to the main operator. According to the results of this study, the current occupational annual dose limit to the lens of the eye of 20 mSv can be exceeded with only two hepatic chemoembolization procedures per week if adequate radiation protection conditions are not guaranteed.

Introduction Hip fracture is one of the main causes of morbidity and mortality among the elderly population. In Colombia there is a shortage of scientific literature on the perioperative management of this population of patients. Objective To describe the perioperative management of hip fracture patients at a tertiary university hospital in Cali, Colombia. Methods An observational study was conducted with relational scope of a historical cohort of patients with hip fracture who underwent surgical management between January 2018 and June 2022. A non-probability sampling method was used and contingency tables were designed aimed at describing the relationship between the patients' characteristics and the postoperative outcomes. Results 235 patients were included, of which 57 % were males. The mean age was 79 years and 49.8 % were classified as ASA III or higher. Spinal anesthesia was the most commonly used technique in 63.4 % of the cases. The most frequent outcomes were delirium in 17.9 %, and acute kidney failure in 6.8 %. 83.4 % of the patients underwent surgery within 48 hours of admission to the emergency department and intra-hospital mortality was 2.6 %. Conclusions The results of this study provide relevant information to identify opportunities for improvement and their implementation, such as the reduction in the time elapsed until surgical management and the development of care protocols in the region.

Introduction: Postoperative nausea and vomiting (PONV) are common complications in surgical patients undergoing general anesthesia, and multiple strategies have been suggested to prevent them. Objective: To describe the available evidence on the effectiveness of pharmacological and nonpharmacological strategies for preventing PONV in adults undergoing surgery under general anesthesia, as reported in previous meta-analyses and systematic reviews. Methodology: An overview of systematic reviews and meta-analyses was conducted. Searches were performed in PubMed, EBSCO, EMBASE, Cochrane Database, Science Direct, and Scopus, without restrictions as to gender, clinical condition, or date of publication, including articles in Spanish, French, and English only. Two reviewers independently and in duplicate did the screening, data extraction, quality evaluation, and risk of bias assessment according to AMSTAR-2. The PRISMA and PRIOR statements were followed for reporting. PROSPERO registration number CRD42021251999. Results: Out of 80 candidate articles, three were viable for meta-analysis. 1.5 mg to 18 mg doses of Dexamethasone showed a significant reduction in the risk of PONV, with a RR of 0.48 (95 % CI 0.41-0.57; p<0.001), I2=63 % (p=0.07), and a NNTc of 5 and 7. Other effective strategies included the use of acoustic stimulation/acupuncture/acupressure, 5HT3 antagonists, NK1 antagonists, gabapentinoids, haloperidol, droperidol, metoclopramide, midazolam, mirtazapine, among others. The risk of publication bias was low. Conclusion: Different strategies are effective for PONV prophylaxis in surgeries under general anesthesia. Dexamethasone shows the best available evidence at the moment. The documented methodological quality suggests the need for better studies to establish the effectiveness of the strategies.

The relationship between cardiac output and anesthetic drugs is important to anesthesiologists, since cardiac output determines the speed with which a drug infused into the bloodstream reaches its target and the intensity of the drug's effect. But rather than focus on how anesthetic drugs affect cardiac output, this narrative review focuses on how changes in cardiac output affect the pharmacokinetics and pharmacodynamics of general anesthetics during the three phases of anesthesia. At induction, an increase in cardiac output shortens both the onset time of propofol for hypnosis and the neuromuscular blocking effect of rapid-acting neuromuscular blockers, favoring the conditions for rapid sequence intubation. During maintenance, changes in cardiac output are followed by opposite changes in the drug plasma concentration of anesthetic drugs. Thus, an increase in cardiac output followed by a decrease in the plasma concentration of the anesthetic could expose the patient to a real risk of intraoperative awakening, which can be avoided by increasing the dose of hypnotic drugs. At emergence, an increase in cardiac output secondary to an increase in pCO2 allows for a more rapid recovery from anesthesia. The pCO2 can be increased by adding CO2 to the respiratory circuit, lowering the ventilatory rate, or placing the patient on partial rebreathing. Finally, the reversal action of sugammadex for rocuronium-induced neuromuscular block can be shortened by increasing the cardiac output. [ABSTRACT FROM AUTHOR]

Frequency, association and impact measures are key concepts in clinical epidemiology; however, it has been found that a considerable proportion of health students and professionals have no knowledge of how to use or interpret them when reading a scientific paper or conducting research. This article aims to explain the main epidemiological measures, how they are used, derived and interpreted. They are approached from the perspective of each of the most frequently used types of primary quantitative research studies (randomized clinical trials, cohort studies, case-control estudies and cross-sectional studies) in order to provide the reader with the context in which they are used. Moreover, the process for calculating and interpreting each result in a real setting is explained using clinical examples for a better understanding of these concepts and in order to prevent their use from becoming just a mechanical or repetitive exercise.

The Choosing Wisely initiative has become a significant benchmark as a strategy to reduce low value tests and therapies. An original initiative of the American Board of Internal Medicine (ABIM) which has been growing gradually and is now present in over 18 countries, with the support of more than 80 scientific societies around the world. In Colombia, the strategy is being accepted by the Colombian Association of Scientific Societies (ACSC), which with the support of six pioneer Colombian scientific societies, have encouraged the development and implementation of "do not do recommendations", with a view to fulfil the right to self-regulation of human resources in healthcare, reducing those medical behaviors that could be ineffective or harmful to the patient. This article is an overview of the most significant items of the initiative which has been conducted by the ACSC, with the support of the Colombian Society of Anesthesiology and Resuscitation (S.C.A.R.E.) as a pioneer.

Timely post-operative pain management in elderly patients is critically important. Given their physiological changes and comorbidities, management in this group of patients is different from the rest of the population. Knowledge of potentially inappropriate medications (Beers criteria) is relevant because of the presence of comorbidities in this population. Although acetaminophen continues to be safe, non-steroidal anti-inflammatory agents produce several adverse effects which need to be considered before they are used. On the other hand, opioids continue to be one of the pillars in analgesia, with due consideration of their adverse affects and interactions, and the need for dose adjustments. Adequate postoperative pain management prevents adverse effects and the risk of developing chronic pain. [ABSTRACT FROM AUTHOR]

Introduction: Apfel simplified risk score for postoperative nausea and vomiting (PONV) has shown to be useful in anesthesia; however, since it has not been calibrated in regional anesthesia or in pregnant patients, its use in cesarean section is limited. Objective: To develop a prognostic predictive model for postoperative nausea and vomiting in pregnant patients undergoing cesarean section under spinal anesthesia. Methods: In a cohort of 703 term pregnant patients scheduled of cesarean section, 15 variables were prospectively assessed, to design a prognostic predictive model for the development of postoperative nausea and vomiting. A logistic regression analysis was used to construct the model and its calibration and discrimination were based on the Hosmer-Lemeshow test, the calibration curves, and C statistic. Additionally, the internal calibration was performed with the Bootstrap resampling method. Results: Postoperative nausea and vomiting were experienced by 27 % of the patients during the first six hours after surgery. The model included as prognostic variables the development of intraoperative nausea and vomiting, age under 28 years, a history of PONV, the mother's BMI and the weight of the newborn baby. The model showed an adequate calibration (X2: 4.65 p: 0.5888), though a low discrimination (Statistic C = 0.68). Conclusions: A prognostic predictive model was created for the development of PONV in cesarean section. This model was used to build a prognostic scale for the classification of patients into risk groups. [ABSTRACT FROM AUTHOR]

Introduction: The no-ventilation no-oxygenation situation is extremely important due to its high mortality. In these cases, open cricothyroidotomy is indicated. Around fifty percent of the difficulties are the result of inadequate identification of the cricothyroid membrane (CTM). Objective: To determine whether ultrasonography is superior to palpation to identify the CTM at the first attempt. Methods: A systematic review and a meta-analysis were conducted on the identification of the cricothyroid membrane versus palpation in Medline/Central and Embase. Clinical controlled trials and observational studies were included. Two authors independently and in duplicate selected the studies, assessed the biases and extracted the data; a random effects meta-analysis was successfully conducted for the correct identification of the CTM. The risk of bias was assessed and the certainty of the evidence was qualified. CRD42021223961. Results: 464 studies were included of which 15 met the eligibility criteria; 6 were clinical trials y 9 were observational. Ultrasound is superior to palpation in the detection of the CTM (RR 1.88, 95 % CI 1.05-3.36) according to the clinical trials, and it was also superior in observational studies (RR 1.76, 95 % CI 1.36-2.28). The association was preserved in the sensitivity analyses. Conclusions: Ultrasonography is superior to palpation for the correct identification of the TCM, though the certainty of the evidence is low. Further studies with better methodology are needed to improve both certainty and precision. [ABSTRACT FROM AUTHOR]

Introduction: Diaphragmatic surface electromyography is a procedure designed to assess the diaphragm. The physiological values of the electrical activity may have potential use in rehabilitation, sports training, ventilatory support withdrawal in critical care units and follow-up of respiratory disease. Objective: To assess and describe the diaphragmatic function through surface electromyography in a population of individuals during spontaneous and forced breathing. Methods: Observational, exploratory cross-sectional study including subjects with no comorbidities. Diaphragmatic surface EMG was performed measuring the mean quadratic root during tidal volume and vital capacity breathing. The body composition of the participants was also assessed. Results: 28 males and 22 females were included in the study. The mean quadratic root of the tidal volume for two minutes was 13.94 µV for females and 13.31 µV for males. The vital capacity was 23.24 µV for males and 22.4 µV for females. A correlation was identified between the mean quadratic root, weight, and body surface. Conclusions: Mean quadratic root values of tidal volume in two minutes in healthy females and males have been documented. The mean quadratic root values are correlated with the physiological and functional characteristics of the participants. [ABSTRACT FROM AUTHOR]

Introduction Children are susceptible to developing preoperative ketonemia, which can be affected by changes in the circadian rhythm and counter-regulatory hormones. It is unclear whether ketonemia depends on the timing of fasting. Objective To assess the effect of preoperative fasting time (diurnal vs. night) on the preoperative concentration of ketone bodies in children. Methods We conducted a prospective-observational clinical study between September 2020 and March 2021, including children under 48 months of age scheduled for elective surgery. Two groups were identified based on fasting time, as follows: diurnal fasting (group A, n = 40) and nocturnal fasting (group B, n = 52). Demographic data, duration of fasting, time of excess fasting, type of food intake, the concentration of ketone bodies and capillary blood glucose, level of anxiety, and dehydration were analyzed in both groups. Results Diurnal fasting was associated with higher incidence of ketonemia compared with nocturnal fasting (Group A: 62.5% (95% CI 48.1-82.0); group B: 38,5% (95% CI 26.5-52.5), P=0.02). Most of the patients exceeded the duration of fasting recommended by preoperative fasting guidelines (95.6%). The type of food eaten before surgery was significantly associated with the presence of ketonemia (P=0.01). Conclusions Preoperative ketonemia is relatively common in patients under 48 months of age, especially among those who undergo diurnal fasting compared to nocturnal fasting. [ABSTRACT FROM AUTHOR]

Conclusiones: se describió las causas y el manejo anestésico de una paciente que luego de aplicar anestesia intratecal para realizar salpingectomía parcial bilateral se constató fracaso total de la anestesia.

The effects of hypertension on perioperative outcomes are still unclear. No specific systolic or diastolic blood pressure measurement has been determined as the cutoff value to continue with a surgical plan or adjourn. This study is designed as a narrative review of the available scientific evidence on the perioperative management of hypertension. A search was conducted in Pubmed considering the title and abstract; 120 articles were pre-selected of which 55 papers were selected for full-text eligibility and 16 were excluded for a total of 39 articles including ACCF/AHA 2009 and ACC/AHA 2014 on perioperative cardiovascular care; 2013 ESH/ESC, 8 JNC, and the 2017 ACC/AHA/AAPA/ABC Guideline for the Prevention, detection, and management of hypertension in adults. Blood pressure values, target organ damage, and type of surgery should be considered for decision-making in the perioperative period. If surgery is elective, blood pressure fluctuations should be avoided and potential causes should be treated. A patient with mild hypertension with values below SBP 160 and DBP 110 mmHg may be managed in the ambulatory setting during the postoperative period, as long as the clinical conditions are favorable.

Medication errors are the cause of severe lesions and complications, particularly with regards to injectable medications. During anesthesia, several drugs are administered simultaneously and quite easily the wrong medication may be administered, leading to morbidity and mortality. Different strategies have been devised to reduce error, including the use of color and letters to facilitate the identification of the various medications and improving safety in anesthesia.

The social determinants of health are the social characteristics in which people's lives and work develop, giving them the capacity to act in specific contexts and are responsible for the health conditions of individuals and populations. Recent World Bank data show that Colombia has made modest progress in terms of social equity. These data reveal that neonatal mortality in remote areas of the country is similar to that found in Sub-Saharan Africa. In these regions, there is no access to specialized neonatal health services. As for anesthesia services, this age group has the highest mortality and perioperative complication rates related to prematurity, the quality of health services and, especially, the expertise of the anesthesiologist. In Colombia, efforts to implement formal university programs for sub-specialization in pediatric anesthesiology have not received governmental support. Meanwhile, the Colombian Society of Anesthesiology and Resuscitation (S.C.A.R.E.), through its Committee of Pediatric Anesthesiology, has created ongoing education opportunities, which, although important, are insufficient to meet the needs of the country. For this reason, a State policy is required, aimed at meeting its social debt and that considers the specialized training of human resources as a pillar for the promotion of equity in health, so that the surgical neonate does not have to travel in the procurement of services, but rather have the State bring those services to them.

Introduction: Acute respiratory failure remains one of the three leading causes of admission to the intensive care unit (ICU). Self-extubation is an adverse outcome requiring reintubation in 50% of cases. Objective: To assess for determinants (risk factors) of self-extubation and mortality in the ICU by using a generalized estimation equation model (GEE). Methods: The data was collected from a retrospective cohort study from 2017-2020 including all patients admitted to the ICU with mechanical ventilation. Univariate and bivariate analyses were performed. Then, a GEE model was conducted to predict the risk of self-extubation and mortality. Results: A total of 857 subjects were included, with a mean age of 60.5 +/- 17 years-old. Most of the subjects were males (55.2%). An 8.99-fold risk (95%CI 3.83-21.1, p<0.01) of self-extubation was identified in patients with agitation. Exposure to infusion of neuromuscular blockade was also found to increase the risk of self-extubation 3.37 times (95%CI 1.31-8.68, p=0.01). No associations were identified between immobilization and self-extubation (OR 1.38 95%CI 0.76-2.51, p=0.29). Finally, light sedation according to the Richmond Sedation Scale (RASS) between 0 to -2 rather than moderate (RASS-3) reduces the risk of mortality (OR 0.57, 95%CI 0.38-0.83, p<0.01). Conclusions: The main factors resulting in self-extubation were: agitation, delirium, and infusion of neuromuscular blocking agents. An association was found between light sedation and a lower risk of mortality. No association was found between the use of physical restraint and the desired outcome. [ABSTRACT FROM AUTHOR]
