Comorbidity and Operative Time are Stronger Predictors than Age for Palatoplasty Adverse Airway Events, A NSQIP-P Study of 6668 Cases.

Abstract

Adverse airway events (AAEs) are rare but devastating complications following palatoplasty. The purpose of this study is to evaluate patient risk factors for their effect on these complications. We hypothesize that prolonged operative time and the presence of multiple medical comorbidities are risk factors for AAEs. Retrospective cohort study. Participant hospitals in the Pediatric American College of Surgeons National Surgical Quality Improvement Program year 2016-2019. Cases of palatoplasty in children under 3 years of age. Adverse airway events including postoperative reintubation or any requirement of postoperative mechanical ventilation. A total of 6668 patients met inclusion criteria. The median operative time was 126 min (IQR 82). AAEs were identified in 107 (1.6%) patients. The incidence of risk factors was found to increase with age and AAEs were more prevalent in younger and older patients. Although patients in the older age groups had significantly higher burden of comorbidities, differences in age were not independently associated with AAEs. Following multivariable logistic regressions, operative times greater than 2 h, ASA class ≥3, >3 medical comorbidities, and black race were found to be significant independent risk factors. In this large, retrospective database study in palatoplasty, increased operative time, ASA classification ≥3, multiple comorbidities, and black race were independently associated with AAEs.
