To compare the postoperative pain following bipolar diathermy scissors tonsillectomy (higher temperature dissection) with harmonic scalpel tonsillectomy (lower temperature dissection).
Sixty patients aged 7-40 years planned for tonsillectomy with no other concurrent surgery were randomised to either bipolar diathermy scissors or harmonic scalpel as surgical technique. Blinded to the surgical technique, the patients recorded their pain scores (VAS, 0-10) at awakening and the worst pain level of the day in the postoperative period. All intake of pain medication was also recorded.
No statistically significant differences were found between the two groups regarding postoperative pain levels or consumption of pain medication.
Usage of the harmonic scalpel does not render less postoperative pain following tonsillectomy when compared with usage of the bipolar diathermy scissors.
比较双极电凝剪刀扁桃体切除术（高温解剖）与超声刀扁桃体切除术（低温解剖）后的术后疼痛情况。
60例计划行扁桃体切除术且无其他同期手术的7至40岁患者，随机分为采用双极电凝剪刀或超声刀作为手术技术的两组。患者对手术技术不知情，记录其苏醒时的疼痛评分（视觉模拟评分法，0至10分）以及术后当天最严重的疼痛程度。还记录了所有止痛药物的摄入量。
两组在术后疼痛程度或止痛药物消耗量方面未发现统计学上的显著差异。
与使用双极电凝剪刀相比，使用超声刀进行扁桃体切除术后并不会减轻术后疼痛。
