Eleven children required a major medical intervention, and details of their perioperative course are given below. The indications for adenotonsillectomy in patient 1 were both tonsillar abscess and obstructive sleep apnea syndrome (OSAS). Patients 8–10 were admitted electively to the post–intensive care unit (PICU), and patients 1–7 and 11 were admitted to the postanesthesia care unit (PACU). Six children, patients 1–6, required reintubation. Patient 7 required postoperative transfer from the PACU to the PICU.
