Background: Cardiac surgery causes pathophysiological changes that favor the occurrence of pulmonary and functional complications.Objective: To investigate the effects of inspiratory muscle training (IMT) with an electronic device on patients undergoing cardiac surgery.Methods: A randomized controlled trial was conducted with 30 adult patients undergoing elective cardiac surgery. A control group (CG) received conventional physical therapy care, and an intervention group (IG) received IMT using the POWERbreathe K5® electronic device. Two daily sessions of physical therapy were performed at the intensive care unit and one daily session at the ward until the sixth postoperative day. The following variables were measured preoperatively and on the sixth postoperative day, in both groups: inspiratory muscle strength, dynamic inspiratory muscle strength, and peak inspiratory flow. Data distribution was evaluated by the Shapiro-Wilk test. Analysis of variance was used, and the results were considered statistically significant when p < 0.05.Results: Maximal inspiratory pressure (71.7 ± 17.1 cmH2O vs 63.3 ± 21.3 cmH2O; p = 0.11], S-index (52.61 ± 18.61 vs 51.08 ± 20.71), and peak inspiratory flow [(2.94 ± 1.09 vs 2.79 ± 1.26)] were maintained in the IG but had a significant reduction in the CG. Conclusion:IMT performed with an electronic device was effective at maintaining inspiratory muscle strength, dynamic inspiratory muscle strength, and peak inspiratory flow when compared to conventional physical therapy.

O objetivo deste estudo foi analisar fatores associados aos óbitos por COVID-19 em gestantes brasileiras. Trata-se de um transversal, com 7296 gestantes brasileiras com diagnóstico de COVID-19 no ano de 2021. Os dados foram coletados do sistema de informação em saúde OPEN DATASUS. O desfecho estudado foi óbito, e as covariáveis foram referentes a questões sociodemográficas e epidemiológicas. Foi realizada análise de regressão logística, com estimativa de odds ratio (OR) e seus respectivos intervalos de confiança de 95% (IC95%), com nível de significância de 5%. Os fatores associados ao óbito em gestantes foram: residir na região nordeste (OR = 1,37; IC95% 1,03 – 1,82), ter alguma comorbidade (OR = 1,80; IC95% 1,48 – 2,21), internação em UTI (OR = 2,56; IC95% 1,99 – 3,30) e ter feito uso de suporte ventilatório invasivo (OR = 18,73; IC95% 12,89 – 27,21). Deve-se buscar e aplicar serviços de saúde integrais em seus recursos físicos e humanos para uma assistência de qualidade e eficiente com maior atenção ao perfil de gestantes encontrado.
