探讨FOCUS超声刀在老年甲状腺手术中的临床疗效和安全性。

选取2014年1月至2017年6月山东滨州医学院烟台附属医院收治的87例老年甲状腺手术患者，其中采用FOCUS超声刀治疗42例（超声刀组），采用电刀治疗45例（电刀组），比较两组患者手术时间、住院时间、切口长度、术中出血量、术后引流量等手术情况，以及术后感染、术后出血、一过性声音嘶哑、永久性声音嘶哑、暂时性低钙血症、永久性低钙血症等并发症的发生情况。两组间的比较采用t检验。

与电刀组相比，超声刀组手术时间、住院时间均显著短于电刀组（t=14.283、27.021，均P<0.01），切口长度、术中出血量、术后引流量均显著少于电刀组（t=19.427、10.298、25.034，均P<0.01）。超声刀组术后并发症发生率显著低于电刀组，差异有统计学意义（4.76%、15.56%，P<0.01）。

FOCUS超声刀在老年甲状腺手术中具有比电刀更好的临床疗效和安全性，值得临床推广应用。

To investigate the clinical efficacy and safety of harmonic FOCUS scalpel in thyroid surgery.

87 elderly patients with thyroid surgery were divided into the harmonic scalpel group (42 cases) and the electrotome group (45 cases). Compared the operative efficacy (including operation time, hospitalization time, incision length, intraoperative hemorrhage and postoperative drainage) and postoperative complications (postoperative infection, postoperative hemorrhage, one-time hoarseness, permanent hoarseness, temporary hypocalcemia, and permanent hypocalcemia) between the two groups. T test was used for comparison between the two groups.

The operating time and hospitalization time in the harmonic scalpel group were significantly shorter than those in the electrotome group (t=14.283, 27.021, P<0.01), the incision length, intraoperative bleeding volume, and postoperative drainage in the harmonic scalpel group were significantly lower than those in the electrotome group (t=19.427, 10.298, 25.034, P<0.01). The incidence of postoperative complications in the harmonic scalpel group was significantly lower than that in the electrotome group (χ²=8.051, P<0.01).

Harmonic FOCUS scalpel has better clinical efficacy and safety in elderly thyroid surgery, which is worthy of clinical application.
