手臂下垂对手背静脉穿刺效果的影响

Accuracy of Venepuncture of Superficial Vein Turgidity in Dorsum of Hand Through the Method of Arm Droop

目的探讨手背静脉充盈方法 ,提高静脉穿刺成功率。方法对 14 7例住院输液病人采用自身对照法 ,单日采用常规法穿刺 14 7例次 (常规法 ) ;双日采用手臂下垂 2min后再扎止血带穿刺 14 7例次 (下垂法 )。结果两组静脉充盈度、扎止血带及进针时间 ,穿刺成功率比较 ,差异有显著性意义 (均P <0 .0 1) ,下垂法明显优于常规法 ;疼痛程度差异无显著性意义 (P >0 .0 5 )。结论采用手臂下垂法 ,能增加静脉充盈度 ,缩短扎止血带后寻找穿刺血管的时间 。

Objective To explore the method of superficial vein turgidity in the dorsum of hand and increase the accuracy of venepuncture. Methods By using auto-control trial, 147 patients were randomly dnided into experimental group and control group. The superficial vein in experimental group was punctured after tying hemostasia band when patients’ arms had drooped, but that in control group was punctured as usual. Results There was significant differences in superficial vein turgidity and in accuracy of venepuncture between two groups (all P<0.01), but there was no significant differences in pain (P>0.05). Conclusion After tying hemostasia band when patients’ arms had drooped the superficial vein turgidity can be improved and accuracy of venepuncture can be increased.
