ObjectivesTo characterize postoperative respiratory complications following adenotonsillectomy (AT) in children with obstructive sleep apnea (OSA) and to identify variables associated with pediatric intensive care unit (PICU) admission.MethodsRetrospective analysis of 133 pediatric OSA patients with prior AT. Assessment of the postoperative hospital course informed patient stratification based on respiratory event severity, PICU admission status, and unscheduled escalation of care.ResultsThirty-six (26.8%) patients were admitted to the PICU. Compared to non-PICU admissions, these patients were significantly younger and with greater preoperative apnea-hypopnea indices, comorbidities, and percentage of post-anesthesia care unit (PACU) time requiring supplemental oxygen. Seventy-one respiratory events occurred in 59 patients, with 60.6% affecting PICU patients. Fifteen severe events occurred, affecting 31% of PICU patients. Of 14 unscheduled escalations of care, 7 were PICU admissions who, compared to planned PICU admissions, spent significantly more time in the PACU and exhibited a trend towards greater PACU time on supplemental oxygen.ConclusionsPediatric patients requiring post-AT PICU care have more risk factors for respiratory compromise. Total PACU time and total PACU time requiring supplemental oxygen may indicate patient risk for postoperative respiratory complications and need for intensive care. Future work includes prospective determination of appropriate post-AT PICU admission.
