“…There are studies evaluating the utility of polysomnography (PSG) in predicting outcomes from adenotonsillectomy, 8,9 but these studies do not evaluate the role of PSG in predicting which patients are at risk for adverse outcomes in the immediate postoperative period. There is evidence to suggest that younger patients, 10,11 patients with multiple medical comorbidities, [10][11][12] patients with worse apnea-hypopnea indexes (AHIs), 11,13 and patients with lower nadir oxygen saturations 11,13,14 are at higher risk for respiratory complications. We hypothesized that PSG variables can be used to predict which patients are more likely to have a respiratory complication that will require treatment in the immediate postoperative period.…”
