RESUMO RACIONAL: A pandemia de COVID-19 teve um efeito negativo na educação cirúrgica na América Latina, diminuindo o treinamento cirúrgico dos residentes e a prática clínica supervisionada. OBJETIVOS: Identificar estratégias que foram propostas ou implementadas para adaptar o treinamento cirúrgico e a prática clínica supervisionada às limitações relacionadas ao COVID-19 na América Latina. MÉTODOS: Foi realizada revisão de literatura entre abril-maio de 2021, dividida em duas buscas. O primeiro procurou identificar estratégias de adaptação em América Latina para treinamento cirúrgico e prática clínica supervisionada. A segunda foi realizada como complemento para identificar metodologias propostas no resto do mundo. RESULTADOS: Na primeira busca, foram selecionados 16 dos 715 artigos. Na segunda, foram selecionados 41 dos 1.637 artigos. Estratégias adaptativas propostas na América Latina com foco em videoconferência e simulação. No resto do mundo, foram sugeridas análises críticas remotas de cirurgias gravadas/ao vivo, tele-mentoria intra-cirúrgica e gravação de cirurgia com feedback pós-operatório. CONCLUSÕES: Múltiplas estratégias de adaptação para educação cirúrgica durante a pandemia de COVID-19 foram propostas na América Latina e no resto do mundo. Há uma oportunidade de implementar novas estratégias a longo prazo para treinamento cirúrgico e prática clínica supervisionada, embora mais estudos prospectivos sejam necessários para gerar recomendações baseadas em evidências.

ABSTRACT BACKGROUND: The COVID-19 pandemic has had a negative effect on surgical education in Latin America, decreasing residents’ surgical training and supervised clinical practice. AIMS: This study aimed to identify strategies that have been proposed or implemented to adapt surgical training and supervised clinical practice to COVID-19-related limitations in Latin America. METHOD: A literature review was performed between April and May 2021, divided into two searches. The first one sought to identify adaptation strategies in Latin America for surgical training and supervised clinical practice. The second one was carried out as a complement to identify methodologies proposed in the rest of the world. RESULTS: In the first search, 16 of 715 articles were selected. In the second one, 41 of 1,637 articles were selected. Adaptive strategies proposed in Latin America focused on videoconferencing and simulation. In the rest of the world, remote critical analysis of recorded/live surgeries, intrasurgical tele-mentoring, and surgery recording with postoperative feedback were suggested. CONCLUSIONS: Multiple adaptation strategies for surgical education during the COVID-19 pandemic have been proposed in Latin America and the rest of the world. There is an opportunity to implement new strategies in the long term for surgical training and supervised clinical practice, although more prospective studies are required to generate evidence-based recommendations.

Anesthesiology became the first Chilean medical specialty certification board to incorporate an objective structured clinical examination (OSCE) into its certification system. The main reason for the introduction of an OSCE is to include an evaluation that allow candidates to demonstrate what they really “do” in clinical practice domains. Inherent in this justification is that the OSCE detects competences that are not well evaluated in current written and oral exams. This article describes the process of implementing an OSCE in Anesthesiology certification and a description of its application after one year of operation.

Resumo Justificativa A isquemia miocárdica perioperatória é comum em pacientes submetidos à cirurgia de fratura de quadril. Nosso objetivo foi avaliar a eficácia do bloqueio perioperatório contínuo do plexo lombar na redução do risco de eventos cardíacos isquêmicos em pacientes idosos submetidos à cirurgia para fraturas de quadril, expresso como uma redução de eventos isquêmicos por indivíduo. Métodos Pacientes com mais de 60 anos de idade, ASA II–III com fatores de risco para ou com doença coronariana conhecida foram incluídos neste estudo controlado e randomizado. Os pacientes foram aleatorizados para analgesia convencional usando analgésicos opioides para administração de analgesia intravenosa controlada pelo paciente (Intravenous Patient-Controlled Analgesia – IVPCA) ou analgesia contínua com o bloqueio do Plexo Lombar (PL), ambas iniciadas no pré-operatório e mantidas até o terceiro dia de pós-operatório. Monitoração contínua de ECG com análise do segmento ST foi registrada. Enzimas cardíacas seriadas e escores de dor foram registrados durante todo o período. Medimos a incidência de eventos isquêmicos por indivíduo registrados com monitoração contínua do segmento ST via Holter. Resultados Trinta e um pacientes (IVPCA 14, PL 17) foram incluídos. Não houve eventos cardíacos sérios durante o período de observação. O número de eventos isquêmicos registrados por sujeito durante o período de observação foi de seis no grupo PL e três no grupo IVPCA. Essa diferença não foi estatisticamente significativa (p = 0,618). Não houve diferenças estatisticamente significativas no número de casos com aumento dos valores de troponina no perioperatório (três casos no grupo LP e um caso no grupo IVPCA) ou em termos de escores de dor. Conclusões O uso da analgesia perineural contínua comparado ao da analgesia sistêmica convencional não modifica a incidência de eventos isquêmicos cardíacos no período perioperatório de pacientes idosos com fratura de quadril.

Abstract Background Perioperative myocardial ischemia is common among patients undergoing hip fracture surgery. Our aim is to evaluate the efficacy of perioperative continuous lumbar plexus block in reducing the risk of cardiac ischemic events of elderly patients undergoing surgery for hip fractures, expressed as a reduction of ischemic events per subject. Methods Patients older than 60 years, ASA II–III, with risk factors for or known coronary artery disease were enrolled in this randomized controlled study. Patients were randomized to conventional analgesia using opioid intravenous patient-controlled analgesia or continuous lumbar plexus block analgesia, both started preoperatively and maintained until postoperative day three. Continuous electrocardiogram monitoring with ST segment analysis was recorded. Serial cardiac enzymes and pain scores were registered during the entire period. We measured the incidence of ischemic events per subject registered by a continuous ST-segment Holter monitoring. Results Thirty-one patients (intravenous patient-controlled analgesia 14, lumbar plexus 17) were enrolled. There were no major cardiac events during the observation period. The number of ischemic events recorded by subject during the observation period was 6 in the lumbar plexus group and 3 in the intravenous patient-controlled analgesia group. This difference was not statistically significant (p = 0.618). There were no statistically significant differences in the number of cases with increased perioperative troponin values (3 cases in the lumbar plexus group and 1 case in the intravenous patient-controlled analgesia group) or in terms of pain scores. Conclusions Using continuous perineural analgesia, compared with conventional systemic analgesia, does not modify the incidence of perioperative cardiac ischemic events of elderly patients with hip fracture.

Background: Simulation is a useful training tool for undergraduate medical students. A valid instrument is needed to assess students’ perception of simulation workshops. Aim: To adapt and validate an instrument to assess the undergraduate medical student’s perception of simulation workshops of clinical procedures. Material and Methods: Delphi Methodology was used to adapt the instrument. Exploratory and confirmatory analyses were performed to determine the construct validity and Cronbach’s Alpha (0 to 1) for internal consistency of the instrument. Results: A Delphi panel of 10 experts adapted a seven-item questionnaire (Likert scale 1-5; ranging from 7 to 35) and four open-questions. After 3-delphi-rounds, the instrument was administered to 210 students in six simulation training programs (Paracentesis, Cardiopulmonary Resuscitation, Airway management, Sutures, Thoracentesis and Nursing Procedures). The instrument was considered unidimensional in the factorial analysis. The overall median (Q1-Q3) score was 34 ranging from 32 to 35 and the Cronbach Alpha coefficient was 0.72, indicating a good reliability. Conclusions: The perception questionnaire is a useful and reliable instrument to assess students’ perceptions of clinical simulations.

Resumo Introdução: O objetivo primário deste estudo foi comparar o efeito da simulação de alta-fidelidade versus autoestudo baseado em resolução de casos no computador, a aquisição de habilidades sobre hipertermia maligna em residentes de anestesiologia do primeiro ano. Métodos: Após a aprovação do Comitê de Ética institucional, 31 residentes de anestesiologia do primeiro ano foram inscritos neste estudo prospectivo, randômico e encoberto. Os participantes foram randomizados para um ambiente de simulação de alta-fidelidade (SAF) ou um estudo de caso (EC) em computador sobre hipertermia maligna. Após a intervenção, o desempenho de todos os indivíduos foi avaliado através de um ambiente de simulação de alta-fidelidade utilizando uma rubrica de avaliação previamente validada. Além disso, uma pesquisa de satisfação e testes de conhecimento foram aplicados. Por fim, uma entrevista semiestruturada foi realizada para avaliar a autopercepção do processo de raciocínio e da tomada de decisão. Resultados: Vinte e oito residentes do primeiro ano concluíram o estudo com sucesso. Os escores dos residentes na aquisição de habilidades no manejo da hipertermia maligna foram globalmente maiores no Grupo SAF que no Grupo EC, mas a significância foi em quatro dos oito elementos da rubrica de desempenho: reconhecer os sinais e sintomas (p = 0,025), priorizaras ações iniciais do manejo (p = 0,003), reconhecer complicações (p = 0,025) e comunicação (p = 0,025). As médias dos escores nos questionários de conhecimento pré- e pós-teste melhoraram de 74% para 85% no Grupo SAF e diminuíram de 78% para 75% no Grupo EC (p = 0,032). Em relação à análise qualitativa, não houve diferença nos fatores que influenciaram o processo de raciocínio e de tomada de decisão dos alunos com ambas as estratégias de ensino. Conclusão: O treinamento baseado em simulação com um ambiente de alta-fidelidade de hipertermia maligna foi superior ao estudo de caso em computador, melhorou o conhecimento e as habilidades no manejo de crises de hipertermia maligna, com um nível de satisfação muito bom entre os residentes de anestesia.

Abstract Introduction: The primary purpose of this study was to compare the effect of high fidelity simulation versus a computer-based case solving self-study, in skills acquisition about malignant hyperthermia on first year anesthesiology residents. Methods: After institutional ethical committee approval, 31 first year anesthesiology residents were enrolled in this prospective randomized single-blinded study. Participants were randomized to either a High Fidelity Simulation Scenario or a computer-based Case Study about malignant hyperthermia. After the intervention, all subjects' performance in was assessed through a high fidelity simulation scenario using a previously validated assessment rubric. Additionally, knowledge tests and a satisfaction survey were applied. Finally, a semi-structured interview was done to assess self-perception of reasoning process and decision-making. Results: 28 first year residents finished successfully the study. Resident's management skill scores were globally higher in High Fidelity Simulation versus Case Study, however they were significant in 4 of the 8 performance rubric elements: recognize signs and symptoms (p = 0.025), prioritization of initial actions of management (p = 0.003), recognize complications (p = 0.025) and communication (p = 0.025). Average scores from pre- and post-test knowledge questionnaires improved from 74% to 85% in the High Fidelity Simulation group, and decreased from 78% to 75% in the Case Study group (p = 0.032). Regarding the qualitative analysis, there was no difference in factors influencing the student's process of reasoning and decision-making with both teaching strategies. Conclusion: Simulation-based training with a malignant hyperthermia high-fidelity scenario was superior to computer-based case study, improving knowledge and skills in malignant hyperthermia crisis management, with a very good satisfaction level in anesthesia residents.

Introduction. The medical education has experienced numerous changes. One of these is the use of self-assessment to establish students' progress, even with summative purposes. As far as we know, in our setting there are not studies about the validity and reliability of the use of self-assessment in the educational process. Subjects and methods. The intubations performed during four months by anesthesia residents at Pontificia Universidad Católica de Chile were assessed using the instrument Direct Observation of Procedural Skills (DOPS). Once the patient was intubated, the anesthesia staff in charge of patient's care carried out the resident's assessment and each student performed a self-assessment of the procedure using the same instrument. The level of agreement between staffs and students was established using intraclass correlation (ICC). An opinion survey among the participants about the method was performed. Results. 585 intubations were assessed. 31 students and 30 staff participated in the study. The general ICC was 0.423. The ICC decreased according to the residents' student year reaching the bottom at third year residents with 0.39. All participants were satisfied with the method but they pointed out the lack of previous experience. Conclusions. The agreement between staffs' assessments and students' self-assessment was poor. The lack of participants' experience could affect the results. To properly use self-assessment instruments, they should be implemented in early stages of educational process.

Introducción. La educación médica ha experimentado numerosos cambios. Uno de éstos es el uso de la autoevaluación para establecer la progresión de los estudiantes. Hasta donde sabemos, en la realidad chilena no existen hasta el momento estudios sobre la validez y confiabilidad del uso de la autoevaluación en el proceso educacional. Sujetos y métodos. Las intubaciones traqueales efectuadas durante cuatro meses por los residentes de anestesia de la Pontificia Universidad Católica de Chile se evaluaron utilizando el instrumento 'observación directa de procedimientos y habilidades' (DOPS). Una vez intubado el paciente, el anestesiólogo a cargo efectuó la evaluación inmediata de la técnica de intubación del residente. A su vez, empleando el mismo instrumento, el residente efectuó una autoevaluación del mismo procedimiento. El nivel de acuerdo entre anestesiólogo y residente se estableció mediante el índice de correlación intraclase (ICC). Se realizó una encuesta de opinión sobre el método entre los participantes. Resultados. Se evaluaron 585 intubaciones. Participaron 31 residentes y 30 anestesiólogos. El ICC general fue 0,423. Éste disminuyó a medida que aumentaba el nivel de experiencia de los estudiantes, y alcanzó el nivel más bajo en los residentes de tercer año, con un ICC de 0,39. Anestesiólogos y residentes manifestaron satisfacción con el método, pero poca experiencia previa. Conclusiones. El nivel de concordancia entre las evaluaciones y autoevaluaciones fue bajo. La falta de experiencia previa de los participantes pudo influir en los resultados. Para utilizar adecuadamente instrumentos de autoevaluación, éstos deberían implementarse desde etapas tempranas de la formación.

Malignant hyperthermia is an autosomal dominant genetic disease that affects the skeletal muscle. Specifically corresponds to a hypermetabolic response against triggering agents such as halogenated gases and the muscle relaxant succinylcholine. Because MH is a potentially fatal disease and ocurrs unexpectedly during a surgery, it is important to stablish how should be the perioperative management of these patients. The aim of this review is to present the current knowledge about the incidence, pathophysiology and triggers of malignant hyperthermia in addition to concepts for the safe management of these patients.

La hipertermia maligna es una enfermedad genética autosómica dominante que afecta al músculo esquelético. Específicamente corresponde a una respuesta hipermetabólica frente a agentes gatillantes como los gases halogenados y el relajante muscular succinilcolina. Debido a que la HM es una enfermedad potencialmente letal e inesperada, que ocurre durante una cirugía, es importante establecer claramente como debe ser el manejo perioperatorio de estos pacientes. El objetivo de esta revisión es presentar los conocimientos actuales sobre la incidencia, fisiopatología y factores desencadenantes de la hipertermia maligna, además de conceptos para el manejo seguro de estos pacientes.

Clinical simulation is defined as a technique (not a technology) to replace or amplify real experiences with guided experiences that evoke or replicate substantial aspects of the real world in a fully interactive fashion. Over the pastfew years, there has been a significant growth in its use, both as a learning tool and as an assessment for accreditation. Example of this is the fact that simulation is an integral part of medical education curricula abroad. Some authors have cited it as an unavoidable necessity or as an ethical imperative. In Chile, its formal inclusion in Medical Schools' curricula has just begun. This review is an overview of this important educational tool, presenting the evidence about its usefulness in medical education and describing its current situation in Chile.

Metrorraghia is one of the most common cause of gynecological morbidity. Transcervical endometrial resection is a good alternative treatment for specific cases. 102 endometrial resections are analysed including age, operating time, complications, pathological results, hysteroscopic controls and follow up. We conclud that the transcervical endometrial resection has 87% of good results, has few complications and the uterine cavity stays permeable for future evaluations.

Siendo la metrorragia una causa frecuente de morbilidad ginecológica, se plantea la resección endometrial como una buena alternativa de tratamiento en casos seleccionados. Se analizan 102 resecciones endometriales realizadas en mujeres que cumplían requisitos definidos de inclusión y exclusión. Los resultados consideran la edad, el tiempo operatorio, las complicaciones, los resultados anatomopatológicos, los controles histeroscópicos y el seguimiento. Se concluye que la resección endometrial tiene éxito en un 87% de los casos, posee pocas complicaciones y las cavidades uterinas permanecen permeables para futuras evaluaciones.
