Predictors of Prolonged Mechanical Ventilation in Pediatric Patients with Hemolytic Uremic Syndrome

Abstract

This study aimed to analyze factors associated with mechanical ventilation (MV) and prolonged MV (≥12 days) in pediatric hemolytic uremic syndrome (HUS) patients. Retrospective multicenter cohort study analyzed data from 3,831 pediatric HUS (age <18 years) patients between 2004 and 2018 from Pediatric Health Information System database. Multivariate logistic regression was used to pinpoint factors associated with MV and prolonged MV. Among 3,831 patients analyzed, 769 (20%) patients required MV, 166 (23.6%) of them were prolonged MV. Factors independently associated with prolonged MV include African American (adjusted odds ratio [aOR]: 1.98, 95% confidence interval [CI]: 1.11–3.54, p = 0.02), children aged between 1 and 5 years (aOR: 7.69, 95% CI: 3.71–15.93, p < 0.001), pneumonia (aOR: 2.54, 95% CI: 1.51–4.25, p < 0.001), pneumothorax (aOR: 2.41, 95% CI: 1.08–5.39, p = 0.032), liver dysfunction (aOR: 3.22, 95% CI: 1.68–6.16, p < 0.001), ileus with perforation (aOR: 1.83, 95% CI: 1.03–3.25, p = 0.039), and sepsis (aOR: 1.97, 95% CI: 1.26–3.08, p = 0.003). In pediatric HUS cases, 20% required MV, and 23.6% of them were prolonged MV. Factors associated with prolong MV include African American race, children aged between 1 and 5 years, pneumonia, pneumothorax, liver dysfunction, ileus with perforation, and sepsis.
