After the surgical procedure of tonsillectomy, hemorrhage ranks among its serious postoperative complications. In this systematic review, we analyze hemorrhage following tonsillectomies performed using the coblation technique. 24 prospective, randomized, and controlled studies were included in the meta-analysis. Data of 796 patients who had undergone coblation tonsillectomy were analyzed. Hemorrhages occurred in 33 patients: 2 classified as primary and 26 as secondary hemorrhages. 5 could not be classified into either group. Overall, the total hemorrhage rate for the coblation procedure was 4.1% with a 95% confidence interval from 2.8 to 5.5%. The overall hemorrhage rate of 4.1% found in this meta-analysis shows that coblation is a safe and effective technique for tonsillectomies with a secondary bleeding rate similar to what is reported for comparable techniques such as bipolar diathermia.

扁桃体切除术后，出血是其严重的术后并发症之一。在这项系统评价中，我们分析了使用等离子技术行扁桃体切除术的术后出血情况。共纳入 24 项前瞻性、随机对照研究进行荟萃分析。分析了 796 例行等离子扁桃体切除术患者的数据。33 例患者发生出血：2 例为原发性，26 例为继发性。5 例无法归入任何一组。总的来说，等离子手术的总出血率为 4.1%，95%置信区间为 2.8%至 5.5%。本荟萃分析发现的 4.1%的总出血率表明，等离子技术是一种安全有效的扁桃体切除术方法，其继发性出血率与双极电凝等类似技术报道的相似。
