Objectives: To identify factors associated with prolonged mechanical ventilation (pMV) in pediatric patients in pediatric intensive care units (PICUs)., Design: Secondary analysis of a prospective cohort., Setting: PICUs in centers that are part of the LARed Network between April 2017 and January 2022., Participants: Pediatric patients on mechanical ventilation (IMV) due to respiratory causes. We defined IMV time greater than the 75th percentile of the global cohort., Interventions: None., Main Variables of Interest: Demographic data, diagnoses, severity scores, therapies, complications, length of stay, morbidity, and mortality., Results: 1698 children with MV of 8±7 days were included, and pIMV was defined as 9 days. Factors related to admission were age under 6 months (OR 1.61, 95% CI 1.17-2.22), bronchopulmonary dysplasia (OR 3.71, 95% CI 1.87-7.36), and fungal infections (OR 6.66, 95% CI 1.87-23.74), while patients with asthma had a lower risk of pIMV (OR 0.30, 95% CI 0.12-0.78). Regarding evolution and length of stay in the PICU, it was related to ventilation-associated pneumonia (OR 4.27, 95% CI 1.79-10.20), need for tracheostomy (OR 2.91, 95% CI 1.89-4.48), transfusions (OR 2.94, 95% CI 2.18-3.96), neuromuscular blockade (OR 2.08, 95% CI 1.48-2.93), high-frequency ventilation (OR 2.91, 95% CI 1.89-4.48), and longer PICU stay (OR 1.13, 95% CI 1.10-1.16). In addition, mean airway pressure greater than 13cmH2O was associated with pIMV (OR 1.57, 95% CI 1.12-2.21)., Conclusions: Factors related to IMV duration greater than 9 days in pediatric patients in PICUs were identified in terms of admission, evolution, and length of stay., (Copyright © 2023 Elsevier España, S.L.U. and SEMICYUC.
