Clinical profile and success in patient extubation after cardiac surgery

Abstract

INTRODUCTION: Patients undergoing cardiac surgery require invasive mechanical ventilation after the surgical procedure. Postoperative extubation, when successful, is related to shorter hospital stay, reduced costs and resources used and decreased morbidity and mortality rates. OBJECTIVE: To identify the profile and number of reintubations of patients undergoing cardiac surgery. MATERIALS AND METHODS: Quantitative, cross-sectional retrospective study, with collection of secondary data obtained from electronic medical records at a Municipal Hospital in the Metropolitan Region of Porto Alegre/RS. Were included 57 medical records of patients who underwent cardiac surgery between January and December 2017 and excluded those under the age of 18 and / or previously extubated in the surgery block. RESULTS: The sample consisted of 22 women (38.6%) and 35 men (61.4%), with a mean age of 61.60 ± 12.33 years. 37 myocardial revascularization surgeries were performed (64.9%), seven of which were associated with valve replacement. Regarding weaning, 96.5% of the patients were successful in extubation, 77.2% spent less than 24 hours on invasive mechanical ventilation and 15.8% were reintubated. The average length of hospital internment was 22.77 ± 17 days and in the Intensive Care Unit was 8.53 days, being that 80.7% of patients discharged from this unit. CONCLUSION: The clinical, sociodemographic and surgical characterization of patients undergoing cardiac surgery is similar to the findings in the literature, a prevalence of elderly and male patients and a low rate of reintubation.
