Objective To evaluate the intra- and interexaminer reproducibility of measurements of the resistance and static and dynamic compliance of the respiratory system in patients on mechanical ventilation. Methods This was an analytical study conducted with individuals aged ≥ 18 years who were on invasive mechanical ventilation and had no clinical diagnosis of respiratory system disease and/or chest abnormality. Three measurements of respiratory mechanics were performed with a 1-minute interval between them. The first and third measurements were performed by examiner A, the second by examiner B. The values for the resistance and static and dynamic compliance of the respiratory system were compared using the intraclass correlation coefficient. Results A total of 198 measurements of respiratory mechanics were performed for 66 patients on mechanical ventilation. The patients had a mean age of 52.6 ± 18.6 years and a mean body mass index of 21.6 ± 2.1kg/m 2 ; a surgical profile (61.5%) and female sex (53.8%) were predominant. Mean values were obtained for the three measurements of respiratory system resistance (A1: 15.7 ± 6.8cmH 2 O/L/s; B1: 15.7 ± 6.4cmH 2 O/L/s and A2: 15.9 ± 6.2cmH 2 O/L/s), respiratory system static compliance (A1: 42.1 ± 13.7mL/cmH 2 O; B1: 42.4 ± 14.6mL/cmH 2 O and A2: 42.2 ± 14.5mL/cmH 2 O) and respiratory system dynamic compliance (A1: 21.3 ± 7.3mL/cmH 2 O; B1: 21.4 ± 7.5mL/cmH 2 O and A2: 21.3 ± 6.2mL/cmH 2 O). The intraclass correlation coefficient was also calculated for respiratory system resistance (R = 0.882 and p = 0.001; R = 0.949 and p = 0.001 - interexaminer A1 versus B and B versus A2, respectively; R = 0.932 and p = 0.001 - intraexaminer); respiratory system static compliance (R = 0.951 and p = 0.001; R = 0.958 and p = 0.001 - interexaminer A1 versus B and B versus A2, respectively; R = 0.965 and p = 0.001 - intraexaminer) and respiratory system dynamic compliance (R = 0.957 and p = 0.001; R = 0.946 and p = 0.001 - interexaminer A1 versus B and B versus A2, respectively; R = 0.926 and p = 0.001 - intraexaminer). Conclusion The measurements of resistance and static and dynamic compliance of the respiratory system show good intra- and interexaminer reproducibility for ventilated patients.
Introdução: a pandemia do SARS-CoV-2 causou impactos econômicos e sociais em todo o mundo, em especial nos sistemas de saúde, repercutindo no número de admissões hospitalares por outras doenças, na rotina dos cuidados, no acesso aos serviços e nos recursos materiais, humanos e financeiros disponibilizados. Objetivo: Analisar o impacto da pandemia SARS-CoV-2 no número de internamentos e mobilização de pacientes críticos de uma unidade de terapia intensiva cardiovascular. Metodologia: trata-se de um estudo transversal, retrospectivo, realizado na Unidade de Terapia Intensiva Cardiovascular do Hospital Geral Roberto Santos, Salvador-BA. Analisaram-se comparativamente os dados de internamento e mobilização dos pacientes, no período entre março de 2019 e fevereiro de 2020, isto é pré-pandemia, e o primeiro ano de sua ocorrência. Resultados: houve redução (p <0,001) no número de internações no setor, quanto a mobilização, embora impactada nos primeiros meses da pandemia, conseguiu manter dados estáveis, quando avaliada de maneira linear. Discussão: A redução na ocupação coincide com achados de estudos nacionais e internacionais, o que pode ter influência na orientação de distanciamento social e o receio de contágio pelo vírus. Quanto à mobilização, importante instrumento de atuação fisioterapêutica nas UTI, apresentou dados similares (p= 0,8), quando comparados os dois períodos do estudo. Conclusão: notou-se impacto da pandemia no número de internamentos em uma UTI cardiológica durante a pandemia, o que deve ser futuramente estudado para avaliar as reais consequências dessa redução assistencial. Quanto à mobilização, não foi observada alteração significativa na média, antes e após a pandemia.
