【摘要】：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(P0.05)。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(P0.05)。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。
[Abstract]:Objective to study the effects of different power of bipolar electrocoagulation on the thermal injury of mesenteric vascular tissue and the hemostatic effect on the blood vessels in goats. Methods 173 segments of goat mesenteric vascular tissue were amputated and the width of thermal injury was measured with different power of coagulation of mesenteric vessels. The success rate of single electrocoagulation was recorded in mesenteric blood vessel tissue under specific power. Results the smaller the power was, the smaller the width of heat conduction injury was. The difference was statistically significant (P 0.05) .60W power bipolar single coagulation blood vessel closure success rate was higher, thermal injury width was the smallest. Conclusion the bipolar electrocoagulation at about 60 W is more suitable for working power, with small thermal injury range and good hemostatic effect.
