Risk factors for respiratory adverse events after adenoidectomy and tonsillectomy in children with down syndrome: a retrospective cohort study.

Abstract

A multivariable model found evidence that lower average oxygen saturation while asleep was associated with PRAEs requiring intervention in children with Down syndrome. This study highlights the difficulty in predicting complications in this population. •Obstructive sleep apnea syndrome is a major cause of morbidity in the Down syndrome population and is commonly treated with adenoidectomy and/or tonsillectomy. •However, children with Down syndrome are at increased risk for perioperative respiratory adverse events (PRAEs) following adenoidectomy and/or tonsillectomy. •We found that a lower average oxygen saturation asleep is associated with increased odds of PRAEs, adjusting for age, total apnea-hypopnea index, cardiac comorbidity, and minimum oxygen saturation. •This study highlights the difficulty in predicting complications in this population.
