不同功率双极电凝对山羊肠系膜血管热损伤及止血效果的研究

Thermal damage of mesenteric vascular tissues and hemostatic effect in adult goats with bipolar electrocoagulation under different powers

目的 研究双极电凝不同功率对山羊肠系膜血管组织的热损伤程度及对血管的止血效果的影响,指导腹腔镜手术中双极电凝功率的选择。方法 截取173段山羊肠系膜血管组织,以不同功率行肠系膜血管凝断术测量热损伤宽度;特定功率下电凝肠系膜血管组织记录单次电凝血管闭合成功率。结果 55~80 W之间,功率越小,热传导损伤宽度越小,差异有统计学意义（P〈0.05）。60 W功率双极单次电凝血管闭合成功率较高,热损伤宽度最小,差异有统计学意义（P〈0.05）。结论 双极电凝在60 W左右为较适合工作功率,热损伤范围小,血管止血效果好。

[Objective] To study the thermal damage of mesenteric vascular tissues and hemostatic effects on goats with bipolar elcctrocoagulation under different powers. [Methods] 173 case of mesenteric vessels of goats were performed bipolar electrocoagulations under different powers, and the thermal damage width and the success rates of electric coagulation of vascular occlusion for a single time were detected. [ Results] From 55W to 80W, the power was lower, the thermal damage width was smaller （P 〈 0.05）. The success rate was the highest and thermal damage width was the smallest under the 60W （P 〈 0.05）. [ Conclusion ] The 60W may decrease thermal damage and has better vascular closure.
