Outcomes of Gastrostomy and Tracheostomy in Infants Undergoing Truncus Arteriosus Repair: Database Study Using the Pediatric Health Information System.

Abstract

We sought to determine the prevalence of and factors associated with gastrostomy tube placement and tracheostomy in infants undergoing truncus arteriosus repair, and associations between these procedures and outcome. Retrospective cohort study. Pediatric Health Information System database. Infants less than 90 days old who underwent truncus arteriosus repair from 2004 to 2019. None. Multivariable logistic regression models were used to identify factors associated with gastrostomy tube and tracheostomy placement and to identify associations between these procedures and hospital mortality and prolonged postoperative length of stay (LOS; > 30 d). Of 1,645 subjects, gastrostomy tube was performed in 196 (11.9%) and tracheostomy in 56 (3.4%). Factors independently associated with gastrostomy tube placement were DiGeorge syndrome, congenital airway anomaly, admission age less than or equal to 2 days, vocal cord paralysis, cardiac catheterization, infection, and failure to thrive. Factors independently associated with tracheostomy congenital airway anomaly, truncal valve surgery, and cardiac catheterization. Gastrostomy tube was independently associated with prolonged postoperative LOS (odds ratio [OR], 12.10; 95% CI, 7.37-19.86). Hospital mortality occurred in 17 of 56 patients (30.4%) who underwent tracheostomy versus 147 of 1,589 patients (9.3%) who did not ( p < 0.001), and median postoperative LOS was 148 days in patients who underwent tracheostomy versus 18 days in those who did not ( p < 0.001). Tracheostomy was independently associated with mortality (OR, 3.11; 95% CI, 1.43-6.77) and prolonged postoperative LOS (OR, 9.85; 95% CI, 2.16-44.80). In infants undergoing truncus arteriosus repair, tracheostomy is associated with greater odds of mortality; while gastrostomy and tracheostomy are strongly associated with greater odds of prolonged postoperative LOS.
