钝针扣眼穿刺技术在自体动静脉内瘘中的应用

Autogenous arterivenous fistula cannulation by buttonhole technique using dull needle

目的:研究钝针扣眼穿刺技术在自体动静脉内瘘中的应用意义。方法:采用自身前后对照的方法,观察90例血液透析患者实验前(扣眼建立前以锐针穿刺)与实验后(钝针扣眼穿刺)各10次血液透析中穿刺成功、渗血发生、感染发生次数、拔针后压迫时间及疼痛评分。结果:实验后穿刺成功次数显著高于实验前,渗血发生次数、疼痛评分及拔针后压迫时间均显著低于实验前,感染发生次数与实验前差异无统计学意义。结论:钝针扣眼穿刺较普通锐针穿刺有一定的优势,值得临床推广。

Objective：To assess the effects of autogenous arterivenous fistula cannulation by buttonhole technique using dull needle.Methods：Self-control test was performed in 90 patients undergoing maintenance haemodialysis.All patients were subjected to consecutive 10 sessions of hemodialysis,respectively before creating the buttonhole using sharp needle（control group）and buttonhole created using dull needle（test group）.The effects were evaluated as the number of successful puncturing,incidences of hemorrhage and infections as well as compression time at the puncture point and scoring on needle stick pain.Results：Fistula cannulaiton by buttonhole technique using dull needle led to higher number of successful cannulation,lower incidences of hemorrhage and pain scores as well as shorter compression time at the puncture point.However,infection remained no difference before and after test.Conclusion：Autogenous arterivenous fistula cannulation by buttonhole technique using dull needle can be preferred and recommended in hemodialysis.
