虹吸原理在静脉穿刺中的应用

Application of siphon machenism in veinous puncture

目的 :探讨虹吸原理在静脉穿刺中的应用 ,提高静脉穿刺的成功率。方法 :随机将 84例患者分为两组 ,一组用虹吸穿刺法 ,即将输液瓶放置在离穿刺部位 6 0cm左右的下方穿刺 ;一组用常规法。结果 :两组中用虹吸法立即回血占 88 1% ,用常规方法立即回血占 2 1 4 % ,差异有显著性 (P <0 0 5 )。结论 :此法提高了静脉穿刺成功率。

Objective:To improve successful ratio of veinous puncture.Method:84 cases were divided into siphon group and traditional group.In siphon group,transfusion bottle height above puncture point is lower than 60cm.Result:Blood recurrency ratio in siphon group is 88.1% while in traditional group,21.4%(P<0.05).Conclusion:Siphon machenism may help improve puncture successful ratio.
