Excessive daytime sleepiness is a major symptom in obstructive sleep apnea syndrome (OSAS) and can be evaluated using both subjective and objective methods. The Epworth Sleepiness Scale (ESS) is a simple and validated questionnaire for assessing subjective daytime sleepiness in the context of sleep disorders. Although its subjective character may limit the accurate expression of daytime sleepiness, the clinical benefit of sequential ESS is clear and demonstrates how ESS scores evolve in individual patients and how these scores may relate to various parameters. In this context we compared the severity of daytime sleepiness reported at baseline visit with severity of baseline sleepiness assessed, retrospectively, after treatment with automatic positive airway pressure (APAP). We conducted a prospective study that included 66 patients evaluated in a sleep clinic diagnosed with OSAS. The diagnosis was confirmed by in-laboratory or portable sleep studies. Their mean age was 53.3 years and the majority were men (88%, n=58). The ESS was answered during the first interview (baseline daytime sleepiness). During follow-up visits, after APAP treatment, the patient was asked to assess baseline sleepiness, retrospectively, as well as post-treatment sleepiness. The mean baseline ESS score was 11.8, mean retrospective baseline ESS 15.4, with a mean difference of 3.55 (p<0.001 t-Test) and post-treatment ESS 7.3. There was no significant correlation between the difference in ESS score (baseline - retrospective baseline) with the average daily (hours) use of APAP, the apnea-hypopnea index (AHI), the minimal recorded SatO(2), disease duration, body mass index (BMI) and age. Our findings confirm that the severity of subjective sleepiness reported before treatment with positive airway pressure is often underestimated by patients with OSAS.
Obesity is considered one of the most serious public health problems of the modern world. Because it alters the relationship between the lungs, chest wall and diaphragm, it is to be expected that it impacts on the respiratory function. In Portugal, there is not much data about the relationship between obesity and pulmonary function. The aim of this study was to characterize respiratory function in morbidly obese patients and to evaluate whether weight loss in patients submitted to bariatric surgery affects pulmonary function tests (PFT). We conducted a retrospective study with 36 morbidly obese patients submitted to bariatric surgery, with a mean age of 40.6 years, 64% female and with a mean body mass index (BMI) of 49.7 kg/m². All patients were clinical and functionally evaluated before surgery and after their weight had stabilized following surgery. They underwent a complete pulmonary function testing with spirometry, lung volumes, carbon monoxide diffusing capacity (DLCO), maximum respiratory pressures and arterial blood gases analysis. Prior to surgery almost all the patients had functional respiratory changes, 34 had a decrease in functional residual capacity (FRC) 6 of whom a restrictive syndrome. Only 2 patients did not show any functional or arterial blood gas change. After bariatric surgery, BMI decreased to 34 kg/m² and there was a significant improvement in almost all functional parameters with resolution of restrictive disorders. Nevertheless, in 13 patients the FRC remained decreased. After weight loss, the only correlation found was between reduction of BMI and increased FRC (r = -0.371; p = 0.028). This study suggests a relationship between obesity and pulmonary restriction and a positive impact of bariatric surgery in PFT.

Background: Simulation is known as an important tool for the learning of technical and nontechnical skills without endangering patient safety. In Portugal, a National Pedagogical Plan for Anesthesiology Residents was created based on simulation training. This plan was designed according to the objectives set forth by the Portuguese Board of Anesthesiology. This study aimed to evaluate the impact of simulation training courses on the non-technical skills of medical residents in Anesthesiology. Methods: Confidential questionnaires, pre-and post-course, were answered by all the residents that attended the different modules of the simulation training program at
INTRODUCTION: Simulation in anesthesiology has been considered a crucial complementary training for residents of this medical specialty. A National Pedagogical Plan of the Biomedical Simulation Center from Centro Hospitalar e Universitário de Coimbra was designed according to the curricular objectives defined by the Portuguese Board of Anesthesiology. The objective of this study is to analyze the evaluation of the programmatic contents included in the simulation courses from the participants’ point of view.METHODS: Post-course confidential questionnaires were answered by all the anesthesiology residents that attended the different modules. All the questions were answered on a 0-10 scale. This study was conducted at the Biomedical Simulation Center from Centro Hospitalar e Universitário de Coimbra, Portugal, from February 2011 to March 2018.RESULTS: A total of 344 questionnaires were answered. The students considered that all the topics included in the simulation courses are important for the training during residency, being basic pharmacology in anesthesiology (Year I) the less important one being classified with 5.03 (IC 95% 4.83-5.22). All the programmatic contents included in the simulation module of the year IV were classified by the residents with importance higher than 8. This last year was the one where the importance of the topics is all numerically higher than in the other years.CONCLUSION: Given the importance attributed by the residents to the programmatic content included in the simulation courses, we can conclude that the design of the courses was appropriate to the needs and the goals of the anesthesiology residents, as a complement of their internship.
