应用改良seldinger技术在犬股动脉内置入动脉鞘的实验研究

Application of modified seldinger technique in arterial sheath placement of canine femoral artery

目的:探究seldinger技术经相应改良后能否安全有效地应用于犬股动脉的动脉鞘管置入。方法:30只犬随机分成两组,试验组(n=15)应用改良seldinger技术进行右侧股动脉鞘置入,对照组(n=15)采用股动脉切开法行动脉鞘置管,比较两组右股动脉穿刺成功率、置管时间、出血量和血肿发生率。结果:右股动脉穿刺成功率两组无显著差异(试验组100%vs对照组93.3%),置管时间和出血量试验组显著低于对照组(1.971.06分钟vs7.302.35分钟,7.474.89mlvs20.13.9ml),试验组两例发生小血肿,对照组无血肿发生。结论:改良seldinger技术可安全简便地应用于犬股动脉鞘的置入。

Objective：To approach the feasibility of sheath insertion into canine femoral artery with modified seldinger technique.Methods：A total of thirty dogs were randomly divided into the test group （insertion sheath with modified seldinger technique, n=15） or the control group（insertion sheath with arteriotomy, n=15）.success rate of sheath insertion, insertion time, bleeding volume and incidence rate of hematoma were measured.Results：There was no significant difference in success rate of sheath insertion and incidence rate of hematoma between the test group and the control group（100% vs 93.3% and 13.2% vs 0, respectively）.Insertion time and bleeding volume of the test group were significantly less than the control group（1.97 1.06 min vs 7.30 2.35 min and 7.47 4.89ml vs 20.1 3.9ml, respectively）.Conclusion：Insertion of sheath into canine femoral artery with modified seldinger technique is convenient and safety.
