三种穿刺法在早期使用动静脉内瘘中的效果观察

Effect observation of the three approaches of centesis to early treatment of arteriovenous fistula

目的探讨动静脉内瘘早期使用的最佳穿刺方法。方法将150例早期使用内瘘的患者随机分成3组,常规穿刺组用常规穿刺法,不扎止血带组穿刺中不扎止血带,其它步骤同常规穿刺组,肢体垂吊穿刺组穿刺前先让肢体垂吊1￣3min,见内瘘充盈后不扎止血带,再持针穿刺。结果,3种穿刺方法成功率分别为96%、76%、96%,常规穿刺组和肢体垂吊穿刺组成功率高(P<0.05),但肢体垂吊穿刺组未见并发症。结论肢体垂吊穿刺法优于常规穿刺法和不扎止血带穿刺法,适合在临床推广应用。

Objective To explore the best approach of centesis for early treatment of arteriovenous fistula. Methods 150 cases undergoing early use of arteriovenous fistula were randomly divided into three groups: normal centesis group receiving normal centesis, no tourniquets group receiving centesis without tourniquets and limb-suspension centesis group where the limbs were suspended first and centesis was done without tourniquets. Results The success rates for the three groups were 96%, 76% and 96% respectively, indicating statistical difference (P<0.05). In the last group, no complications were found. Conclusion Limb-suspended centesis is more effective in treating arteriovenous fistula.
