OBJECTIVE/HYPOTHESIS: To reconcile conflicting reports and opinions of the value of @entity3459 studies for @entity1 undergoing tonsillectomy. STUDY DESIGN: Meta-analysis: Articles were identified by MEDLINE search, references from review articles, textbook chapter, and retrieved reports. Independent observers selected prospective trials of @entity1 undergoing tonsillectomy or adenoidectomy and tonsillectomy. Retrospective studies meeting other inclusion and exclusion criteria were included for sensitivity analyses of results. METHODS: Data were abstracted from studies for an end point of @entity548 with normal and @entity854 tests. Four prospective studies met all inclusion and exclusion criteria. These four studies were used in the data synthesis. An additional eight retrospective studies met all other criteria and were used in the sensitivity analysis. RESULTS: Pooled analysis of 3384 @entity1 revealed a rate of 3.3% (95% confidence interval [CI], 2.5%-4.1%) for post-tonsillectomy @entity548 in @entity1 with normal coagulation studies. A rate of 8.7% (95% CI, 1.5%-15.9%) was obtained for @entity548 in @entity1 with @entity854 studies. No significant rate difference in post-tonsillectomy @entity548 was demonstrated. CONCLUSION: There is no difference in the rate of post-tonsillectomy @entity548 in @entity1 with @entity854 studies as compared with @entity1 with normal coagulation studies obtained preoperatively.
