There is significant variation among clinicians in preoperative and postoperative care provided for patients undergoing pediatric tonsillectomy. Lawlor and colleagues conducted a retrospective medical chart review of 2139 children aged 3 to 6 who underwent tonsillectomy to assess the association between age, weight, and postoperative complication. The authors found that the odds of having a complication were significantly greater in children younger than 3, especially in the first 24 hours after surgery. No significant association between weight and complication was found. They conclude that healthy children younger than 3 years may be at increased risk for posttonsillectomy complication.
