Ventilação não invasiva em pessoas internadas em serviços de medicina: Estudo retrospetivo

Abstract

Background: Non-invasive ventilation is a therapeutic strategy for patients with acute respiratory failure. Objective: To analyze the relationship between the sociodemographic and clinical variables of patients hospitalized in internal medicine services and the adaptation to and complications of non-invasive ventilation. Methodology: A retrospective observational cohort study was carried out with a sample of 239 patients. Data were collected from electronic records in the information system SClínico , using a data extraction guide. Results: A total of 25.1% of the participants did not adapt to non-invasive ventilation, and this was significantly associated with oral feeding, confusion, and the use of mechanical restraint measures. Complications occurred in 33.5% of the sample. The most frequent complications were secretions, nasal injuries, and vomiting. There was a statistically significant association between the number of complications and patients fed by nasogastric tube, confused, with mechanical restraint measures, and wearing an oronasal mask. Conclusion: The monitoring of patients on non-invasive ventilation should be carried out by a specialized nursing team. Protocols should be implemented to prevent complications and promote patient adaptation to non-invasive ventilation.
