ObjectiveTo determine the safety of a relatively brief (<3-hour) period of postoperative observation prior to discharge in children undergoing outpatient tonsillectomy.DesignRetrospective chart review.SettingTertiary care children's hospital and public teaching hospital.PatientsThe records of all patients (12 years of age who underwent tonsillectomy or adenotonsillectomy from November 1995 through July 1997 were reviewed. A total of 143 patients scheduled for ambulatory treatment were identified; 9 were excluded owing to insufficient follow-up. The remaining 134 patients made up the study group.Main Outcome Measures(1) Duration of observation prior to discharge; (2) complication rates.ResultsThe mean age of the study population was 6.1+/-2.6 (mean+/-SD) years. Obstructive sleep apnea was an indication for surgery in 86.5%. Eleven (8.2%) of 134 planned outpatients were electively admitted from the recovery room for inpatient observation, most often because of respiratory compromise. Patients admitted from the recovery room were significantly younger (mean age, 4.0 years) than those who were discharged as planned (6.3 years, P<.001). One hundred twenty-three patients were discharged from the recovery room as anticipated, following a mean+/-SD duration of postoperative observation of 144+/-48 minutes. Overall, 5 (4.1%) of these 123 outpatients suffered complications after discharge. Two patients (1.6%) experienced primary bleeding, both at 8 hours after surgery. Four patients (3.2%) were readmitted. The complication rate did not vary significantly with the duration of postoperative observation (P= .71).ConclusionA short postoperative observation period is safe, with a low rate of complications, in appropriately selected children scheduled for ambulatory tonsillectomy.
