RESUMO

BACKGROUND: Simulation-based education has become the most important part of resident training in anesthesiology, especially during the pandemic. It allows learning the skills and the management of different situations without putting residents in risk of contamination, considering COVID-19 is highly contagious. The hypothesis was that simulation is still associated with improvement of knowledge acquisitions despite the context of the COVID-19 pandemic. METHODS: Residents of anesthesiology and intensive care subjected to an anaphylaxis simulation scenario. Their knowledge levels were assessed by true/false questions before and one month after the simulation session. The STAI test was used to measure anxiety levels before and after the scenario. Data were analyzed statistically using Wilcoxon and McNemar tests. RESULTS: Junior residents (< 2 years) received significantly higher scores in post-training theoretical tests compared to their pre-training scores (79.2 ± 9.6, 84.5 ± 8.2, p = 0.002, n = 21). There was no difference between pre- and post-test scores of seniors (80.2 ± 9, 81.8 ± 10.4, p = 0.3). Pre- and post-anxiety inventory scores were nearly the same and both were in the moderate group (39.8 ± 10.1, 39.3 ± 12.1, p = 0.8). CONCLUSION: Simulation-based education improved the knowledge levels of the residents without raising anxiety levels. Thus, simulation-based training showed its value as an important tool of education during the pandemic, which needs to be further popularized for training at all institutions. Enlightening medical educators about this accomplished teaching method may lead to improved quality of medical education in developing countries and reshape how tomorrow's doctors are trained during pandemics.

RESUMO

ABSTRACT BACKGROUND AND OBJECTIVES: The aim of this study was to compare the effects of two different doses of intrathecal morphine on postoperative analgesia, postoperative first mobilization and urination times and the severity of side effects. METHODS: After Institutional Ethical Committee approval, 48 ASA I-II patients were enrolled in this randomized double-blinded study. Spinal anesthesia was performed with 0.1 mg (Group I, n = 22) or 0.4 mg (Group II, n = 26) ITM in addition to 7.5 mg heavy bupivacaine. The first analgesic requirement, first mobilization and voiding times, and postoperative side effects were recorded. Statistical analyses were performed using SPSS 15.0 and p < 0.05 was considered as statistically significant. The numeric data were analyzed by thet-test and presented as mean ± SD. Categorical data were analyzed with the chi-square test and expressed as number of patients and percentage. RESULTS: Demographic data were similar among groups. There were no differences related to postoperative pain, first analgesic requirements, and first mobilization and first voiding times. The only difference between two groups was the vomiting incidence. In Group II 23% (n = 6) of the patients had vomiting during the first postoperative 24 h compared to 0% in Group I (p = 0.025). CONCLUSION: For inguinal hernia repairs, the dose of 0.1 mg of ITM provides comparable postoperative analgesia with a dose of 0.4 mg, with significantly lower vomiting incidence when combined with low dose heavy bupivacaine.

RESUMO JUSTIFICATIVA E OBJETIVOS: Comparar os efeitos de duas doses diferentes de morfina intratecal (MIT) sobre a analgesia no pós-operatório, os tempos até a primeira mobilização e micção no pós-operatório e a gravidade dos efeitos colaterais. MÉTODOS: Após a aprovação do Comitê de Ética Institucional, 48 pacientes com estado físico ASA I-II foram incluídos neste estudo randômico e duplo-cego. A raquianestesia foi feita com 0,1 mg (Grupo I, n = 22) ou 0,4 mg (Grupo II, n = 26) de MIT adicionados a 7,5 mg de bupivacaína hiperbárica. Os tempos até a primeira necessidade de analgésico, mobilização e micção e os efeitos colaterais no pós-operatório foram registrados. As análises estatísticas foram feitas com o programa SPSS 15.0 e p < 0,05 foi considerado estatisticamente significativo. Os dados numéricos foram analisados com o teste t e expressos como média ± DP. Os dados categóricos foram analisados com o teste do qui-quadrado e expressos como número de pacientes e porcentagem. RESULTADOS: Os dados demográficos foram semelhantes entre os grupos. Não houve diferenças em relação à dor, aos tempos até a primeira necessidade de analgésicos, à primeira mobilização e primeira micção. A única diferença entre os dois grupos foi a incidência vômito. No Grupo II, 23% (n = 6) das pacientes apresentaram vômito durante as primeiras 24 horas de pós-operatório, em comparação com 0% no Grupo I (p = 0,025). CONCLUSÃO: Para herniorrafia inguinal, a dose de 0,1 mg de MIT fornece analgesia comparável à dose de 0,4 mg, com uma incidência de vômito significativamente menor quando combinada com uma dose baixa de bupivacaína hiperbárica.

RESUMO

BACKGROUND AND OBJECTIVES: Preoperative ultrasonographic evaluation of the thyroid gland done by surgeons could let us foresee airway management challenges. The aim of this observational study was to evaluate the effects of thyroid-related parameters assessed preoperatively by surgeons via ultrasonography and chest X-ray on intubation conditions. METHODS: Fifty patients undergoing thyroid surgery were enrolled. Thyromental distance, Mallampati score, neck circumference and range of neck movement were evaluated before the operation. Thyroid volume, signs of invasion or compression and tracheal deviation on chest X-ray were also noted. The intubation conditions were assessed with Cormack and Lehane score and the intubation difficulty scale. Statistical analyses were done with SPSS 15.0 software. RESULTS: The mean thyroid volume of the patients was 26.38 ± 14 mL. The median intubation difficulty scale was 1 (0-2). Thyromental distance (p = 0.011; r = 0.36; 95% CI 0.582-0.088), Mallampati score (p = 0.041; r = 0.29; 95% CI 0.013-0.526), compression or invasion signs (p = 0.041; r = 0.28; 95% CI 0.006-0.521) and tracheal deviation on chest X-ray (p = 0.041; r = 0.52; 95% CI 0.268-0.702) were correlated with intubation difficulty scale. Also patients were classified into two groups related to their intubation difficulty scale (Group I, n = 19: intubation difficulty scale = 0; Group II, n = 31: 1 < intubation difficulty scale ≤ 5) and difficult intubation predictors and thyroid-related parameters were compared. Only Mallampati score was significantly different between groups (p = 0.025). CONCLUSION: The thyroid volume is not associated with difficult intubation. However clinical assessment parameters may predict difficult intubation. .

JUSTIFICATIVA E OBJETIVOS: A avaliação ultrassonográfica pré-operatória da glândula tireóide feita por cirurgiões pode prever desafios no manejo das vias aéreas. O objetivo deste estudo observacional foi avaliar os efeitos de parâmetros relacionados à tireóide investigados pré-operatoriamente por cirurgiões mediante ultrassonografia e radiografia de tórax em condições de intubação. MÉTODOS: Foram inscritos 50 pacientes submetidos à cirurgia de tireóide. Distância tireomentoniana (DTM), escore de Mallampati, circunferência do pescoço e amplitude de movimento do pescoço foram avaliados antes da operação. Volume da tireóide, sinais de invasão ou compressão e desvio da traqueia na radiografia de tórax também foram registrados. As condições de intubação foram avaliadas com o escore de Cormack e Lehane (CL) e a escala de intubação difícil (EID). Análises estatísticas foram feitas com o software SPSS 15.0. RESULTADOS: A média do volume da tireóide dos pacientes foi de 26,38 ± 14 mL. A mediana da EID foi de 1 (0-2). DTM (p = 0,011; r = 0,36, IC 95% 0,582-0,088); escore de Mallampati (p = 0,041; r = 0,29, IC 95% 013-0,526); sinais de compressão ou invasão (p = 0,041; r = 0,28; IC 95% 0,006-0,521) e desvio da traqueia na radiografia de tórax (p = 0,041; r = 0,52, IC 95% 0,268-0,702) foram correlacionados com a EID. Os pacientes foram classificados em dois grupos também relacionados à EID (Grupo I, n = 19: EID = 0; Grupo II, n = 31: 1 < EID ≤ 5) e os preditivos de intubação difícil e os parâmetros da tireóide relacionados foram comparados. Apenas o escore de Mallampati foi significativamente diferente entre os grupos (p = 0,025). CONCLUSÃO: O volume da tireóide não está associado à intubação difícil. Contudo, os parâmetros de avaliação clínica podem prever intubação difícil. .

JUSTIFICACIÓN Y OBJETIVOS: La evaluación ecográfica preoperatoria de la glándula tiroides hecha por los cirujanos puede prevenir los retos en el manejo de las vías aéreas. El objetivo de este estudio observacional fue evaluar los efectos de parámetros relacionados con la tiroides investigados por cirujanos antes de la operación, mediante ecografía y radiografía de tórax en condiciones de intubación. MÉTODOS: Fueron inscritos 50 pacientes sometidos a cirugía de tiroides.

Las condiciones de intubación se calcularon con la puntuación de Cormack y Lehane y la escala de intubación difícil (EID). Los análisis estadísticos fueron realizados con el software SPSS 15.0. RESULTADOS: La media del volumen de la tiroides de los pacientes fue de 26,38 ± 14 mL. La mediana de la EID fue 1 (0-2). Fueron correlacionados con la EID la distancia tiromentoniana (p = 0,011; r = 0,36; IC 95%: 0,582-0,088), puntuación de Mallampati (p = 0,041; r = 0,29; IC 95%: 013-0,526), signos de compresión o invasión (p = 0,041; r = 0,28; IC 95%: 0,006-0,521) y desviación de la tráquea en la radiografía de tórax (p = 0,041; r = 0,52; IC 95%: 0,268-0,702). Los pacientes fueron clasificados en 2 grupos también relacionados con la EID (grupo i, n = 19: EID = 0; grupo ii, n = 31: 1 < EID ≤ 5), y los predictores de intubación difícil y los parámetros de la tiroides relacionados fueron comparados. Solamente la puntuación de Mallampati fue significativamente diferente entre los grupos (p = 0,025). CONCLUSIÓN: El volumen de la tiroides no está asociado con la intubación difícil. Sin embargo, los parámetros de evaluación clínica pueden prever la intubación difícil. .

RESUMO

BACKGROUND AND OBJECTIVES: The aim of this randomized, double-blinded, prospective study was to determine the effectiveness and side effects of intravenous or epidural use of morphine, bupivacaine or ropivacaine on post-thoracotomy pain management. METHODS: Sixty patients undergoing elective thoracotomy procedure were randomly allocated into 4 groups by the sealed envelope technique. Group IVM, EM, EMB and EMR received patient controlled intravenous morphine, and epidural morphine, morphine-bupivacaine and morphine-ropivacaine, respectively. Perioperative heart rate, blood pressure and oxygen saturation and postoperative pain at rest and during cough, side effects and rescue analgesic requirements were recorded at the 30(th) and 60(th) minutes and the 2(nd), 4(th), 6(th), 12(th), 24(th), 36(th), 48(th), and 72(nd) hour. RESULTS: Diclofenac sodium requirement during the study was lower in Group EM. Area under VAS-time curve was lower in Group EM compared to Group IVM, but similar to Group EMB and EMR. Pain scores at rest were higher at the 12, 24, 36, and 48(th) hour in Group IVM compared to Group EM. Pain scores at rest were higher at the 30(th) and 60(th) minutes in Group EM and Group IVM compared to Group EMB. Pain scores during cough at the 30(th) minute were higher in Group EM compared to Group EMB. There was no difference between Group IVM and Group EMR. CONCLUSIONS: Morphine used at the epidural route was found more effective than the intravenous route. While Group EM was more effective in the late period of postoperative, Group EMB was more effective in the early period. We concluded that epidural morphine was the most effective and preferred one.
