To identify the risk factors related with prolonged MV in children undergoing cardiac surgery (CS) may contribute for early intervention and a better prognosis.Objective: to identify factors associated with prolonged MV in children undergoing CS in northeastern Brazil.Method: retrospective study of childrenunder MV in the postoperative period of CS in a large hospital located in northeastern Brazil during 2012. Children with immunodeficiency, cystic fibrosis, severe neurological disease or respiratory failure were excluded. Descriptive data analysis was performed, followed by simple and multivariate Poisson regression.Results: Of 136 children undergoing MV in the postoperative period of CS, 125 had congenital heart disease. The most frequent diagnoses were interventricular communication (22.8%) and tetralogy of Fallot (19.9%). Categories 1 and 2 RACHS-1 were the most frequent, with 24.4% and 52.8% respectively. Ages ranged from two months to 17 years old (median 52 months), duration of cardiopulmonary bypass (CPB) 20-205 minutes (median 60 minutes) and duration of MV from one to 192 hours (median 5 hours). The overall mortality rate was 2.2%. Multivariate analysis showed that risk factors for prolonged MV (more than 6 hours) were higher categories RACHS-1, prolonged CPB, and the presence of respiratory complications during surgery. However, higher PaO2 showed a protective factor.Conclusion: The risk factors for prolonged MV were: higher categories RACHS-1, prolonged CPB, and the presence of respiratory complications during surgery. While higher PaO2 showed as a protective factor. ER -
