Resultados y repercusión clínico-anestésica de los exámenes complementarios preoperatorios en pacientes ASA I para cirugía ambulatoria / Results and clinical-anesthetic repercussion of preoperative complementary tests in Asa-I patients scheduled for ambulatory surgery

Introducción: La selección de exámenes laboratorios preoperatorios (test específicos o exámenes por imágenes) debe hacerse como medida complementaria en el caso de sospecha clínica. La solicitud indiscriminada y de rutina es innecesaria e implica costos adicionales para la institución, además de la posibilidad de resultados falsos positivos, con repercusiones más o menos graves para los pacientes. Objetivo: Destacar los resultados y la repercusión clínico-anestésica de los exámenes complementarios preoperatorios en pacientes ASA I para cirugía ambulatoria que llegan a cirugía ambulatoria en el Hospital General Docente Comandante Pinares del municipio de San Cristóbal, Artemisa durante el año 2017. Método: Se realizó un estudio observacional de tipo descriptivo, de corte transversal en el Hospital General Docente Comandante Pinares del municipio de San Cristóbal, Artemisa, durante el año 2017. El universo se representa por 823 pacientes que se sometieron a cirugía ambulatoria, la muestra fue de 394 pacientes, según criterio de selección no probabilístico, intencional. Resultados: El sexo con mayor predominio en las cirugías fue el femenino 65,98 por ciento, las edades más frecuentes fue de 18-30 años. La cirugía electiva que más se realizó fue la colecistectomía 43,18 por ciento. En cuanto a los exámenes paraclínicos realizados, se detectó una baja incidencia de alteraciones, la complicación perioperatoria detectada fue la crisis hipertensiva 0,50 por ciento. Conclusión: Los resultados de los exámenes complementarios fueron normal en la mayoría de los pacientes, sin repercusiones o cambios en la conducta clínico anestésica. Además, generaron un elevado gasto a la institución de salud(AU)

Introduction: The selection of preoperative laboratory tests (specific tests or imaging tests) should be done, as a complementary measure, in the case of clinical suspicion. Indiscriminate and routine request is unnecessary and implies additional costs for the institution, in addition to the possibility of false positive results, with more or less serious repercussions for patients. Objective: To highlight the results and the clinical-anesthetic repercussion of complementary preoperative examinations in ASA-I patients who arrive for ambulatory surgery at Commandant Pinares General Teaching Hospital in San Cristóbal Municipality, Artemisa Province, during the year 2017. Method: An observational, descriptive, cross-sectional study was carried out at Commandant Pinares General Teaching Hospital in San Cristóbal Municipality, Artemisa Province, during the year 2017. The universe was represented by 823 patients who underwent ambulatory surgery. The sample consisted of 394 patients, following nonprobabilistic, intentional selection criteria. Results: The sex with the highest prevalence of surgeries was the female sex (65.98 percent). The most frequent ages were between 18 and 30 years. The most performed elective surgery was cholecystectomy (43.18 percent). Regarding the paraclinical examinations performed, a low incidence of alterations was detected; the perioperative complication detected was hypertensive crisis (0.50 percent). Conclusion: The results of the complementary examinations were normal in most of the patients, without repercussions or changes in the clinical anesthetic behavior. In addition, they generated high expenses for the health institution(AU)

Evolução da prevalência de infecção por COVID-19 no Rio Grande do Sul, Brasil: inquéritos sorológicos seriados / Trends in the prevalence of COVID-19 infection in Rio Grande do Sul, Brazil: repeated serological surveys

Resumo A COVID-19 é uma doença produzida pelo vírus SARS-CoV-2. Esse vírus se espalhou rapidamente pelo mundo, o que levou a Organização Mundial da Saúde a classificar a COVID-19 como uma emergência de saúde internacional e, posteriormente, a declará-la uma pandemia. O número de casos confirmados, no dia 11 de abril de 2020, já passa de 1.700.000, porém esses dados não refletem a real prevalência de COVID-19 na população, visto que, em muitos países, os testes são quase que exclusivamente realizados em pessoas com sintomas, especialmente os mais graves. Para definir políticas de enfrentamento, é essencial dispor de dados sobre a prevalência real de infecção na população. Este estudo tem por objetivos avaliar a proporção de indivíduos já infectados pelo SARS-CoV-2 no Rio Grande do Sul, Brasil, analisar a velocidade de expansão da infecção e estimar o percentual de infectados com e sem sintomas. Serão realizados quatro inquéritos sorológicos repetidos a cada 15 dias, com amostragem probabilística de nove cidades sentinela, em todas as sub-regiões do Estado. As entrevistas e testes ocorrerão no âmbito domiciliar. Serão utilizados testes rápidos para detecção de anticorpos, validados previamente ao início da coleta de dados.

Abstract COVID-19, the disease produced by the virus SARS-CoV-2, has spread quickly throughout the world, leading the World Health Organization to first classify it as an international health emergency and, subsequently, declaring it pandemic. The number of confirmed cases, as April 11, surpassed 1,700,000, but this figure does not reflect the prevalence of COVID-19 in the population as, in many countries, tests are almost exclusively performed in people with symptoms, particularly severe cases. To properly assess the magnitude of the problem and to contribute to the design of evidence-based policies for fighting COVID-19, one must accurately estimate the population prevalence of infection. Our study is aimed at estimating the prevalence of infected individuals in the state of Rio Grande do Sul, Brazil, to document how fast the infection spreads, and to estimate the proportion of infected persons who present or presented symptoms, as well as the proportion of asymptomatic infections. Four repeated serological surveys will be conducted in probability samples of nine sentinel cities every two weeks. Tests will be performed in 4,500 participants in each survey, totaling18,000 interviews. Interviews and tests will be conducted at the participants' household. A rapid test for the detection of antibodies will be used; the test was validated prior to the beginning of the fieldwork.
