ObjectiveTo determine the risk of complications after discharge in outpatient adenotonsillectomy after a short (< 6 hours) period of postoperative observation.DesignRetrospective chart review.SettingOutpatient surgery center at a university hospital.PatientsAll patients 18 years of age or less who were scheduled for adenotonsillectomy or tonsillectomy from January 1988 through December 1991. Two hundred fifty-five patient records were reviewed. Twenty-two patients were excluded from the study because of various complicating medical conditions that required planned overnight hospitalization leaving a study population of 233 patients.Main Outcome Measures(1) Rate and type of complications; (2) duration of postoperative observation.ResultsComplication rates of bleeding, emesis, dehydration, and readmission were compared with rates deemed acceptable in the literature (< or = 10%). Power analysis demonstrated that the patient number was sufficient to establish a 95% confidence interval for a complication rate of 0% to 10%. The mean duration of postoperative observation was 136 +/- 48 minutes. Complications included bleeding, emesis, dehydration, and nonscheduled admissions. The total complication rate was 9% (95% confidence interval, 5.5% to 12.7%). The rate of primary bleeding was 1.4%, and all primary bleeding occurred within 75 minutes of arrival in the recovery room; no primary bleeding occurred after discharge from day surgery. This complication rate is comparable with rates previously described in the literature for patients who were observed for a 6- to 12-hour period.ConclusionThe findings in this study suggest that short periods of observation are safe for outpatient pediatric patients undergoing adenotonsillectomy after discharge criteria are met.
