Predictors of perioperative complications in higher risk children after adenotonsillectomy for obstructive sleep apnea: a prospective study.

Objective: Retrospective studies have limitations in predicting perioperative risk following adenotonsillectomy in children with obstructive sleep apnea syndrome (OSAS). Few prospective studies exist. We hypothesized that demographic and polysomnographic (PSG) variables would predict respiratory and general perioperative complications.
