超声刀在开放甲状腺手术中的临床应用研究

目的探讨超声刀在开放性甲状腺手术中应用的安全性以及与传统甲状腺手术的比较。方法收集2007年1月至2007年12月用超声刀行单侧开放性甲状腺次全切除术105例，选取同期传统单侧甲状腺次全切除术105例作为对照。比较两组手术时间、术中出血量以及并发症等指标。结果超声刀组手术时间为（53±10．5）min，传统组为（69±13．2）min，超声刀组平均缩短约18min（P〈0．01）。术中出血量超声刀组为（23±3．4）ml，传统组为（40±5．1）ml，超声刀组平均减少约20ml。超声刀组有3例发生暂时性喉返神经麻痹，传统组有2例喉返神经麻痹，两组差异无统计学意义。结论应用超声刀行开放性甲状腺切除术安全可行，可以明显缩短手术时间，减少术中出血量。

A clinical study on ultrasonically activated scalpel in open thyroid surgery

Objective To evaluate the safety and efficacy of ultrasonically activated scalpel(WAS) in open thyroid surgery. Methods From January 2007to December 2007,the clinical data of 105 consecutive pa-tients undergoing thyroidectomy using the WAS were recorded. The results were compared with those of the 105 patients in the same period using conventional techniques including operation time, the volume of bleeding and complication. Results The mean operetion time of subtotal thyroidectomy in WAS group was (53±10.6) min respectively, and (69±13.2) rain respectively in conventional group. The operation time performed with WAS was 18 rain faster(P<0.01). the volume of bleeding were (23±3.4) ml in WAS group and (40±5.1)ml in conventional group. The volume of bleeding in WAS group were 20 ml less than those in conventional group. In WAS group,the postoperative recurrent laryngeal nerve temporary paralysis occurred in three patients. In con-ventional group, recurrent laryngeal nerve temporary paralysis ocurred in two patients, but there was no statisti-cally significant difference. Conclusion The WAS is a safe alternative for open thyroideetomy. This technique can reduce the operation time and the volume of bleeding significantly.
