防逆流留置针在两种穿刺方法中的效果观察

目的:探讨防逆流留置针在两种穿刺方法中的效果。方法:随机选取病人200例分为两组,试验组100例,对照组100例,试验组采用防逆流留置针在血管上方35度至40度进针,留导管在外端0.01～0.02cm,对照组采用防逆流留置针15度至30度进针,导管全部刺入血管。留针时间4天,观察留置针穿刺点出血情况、发生血液逆流及堵管情况。结果:试验组与对照组在穿刺点出血方面有统计学意义(P<0.05),试验组穿刺点出血明显较试验组少;血液逆流及堵管情况无差异(P>0.05)。结论:防逆流留置针在穿刺过程中,35度至40度进针,留导管在外端0.01～0.02cm,降低了机械性静脉炎的发生,有效防止了穿刺点出血现象,减少了护士更换贴膜的频率,减轻了护士工作量,提高了护士工作效率。

Objective： To explore prevent current remaining needle in both the effect of puncture. Methods： Randomly selected 200 patients divided into two groups, the observation group 100 eases and 100 patients in the observation group, the current remaining needle in preventing vascular above 35 degrees degrees, leave the needle into the tube outer end 0. 01 0. 02 CM, the comparison group uses the anti countercurrent remaining needle 15 degrees - 30 degrees into needle, conduit all penetrate vascular Results： Prevent current remaining needle 35 degrees degrees, leave the needle into the tube outer end 0. 01 0. 02 CM the puncture point bleeding, re- duce the nurse change the frequency of the skin, reduce the workload Conclusion： Prevent current remaining needle puncture in the process, 35 degrees degrees, leave the needle into the tube outer end 0. 01 0. 02 CM, to reduce the mechanical phlebitis occurrence, effectively prevent the puncture point bleeding phenomenon, reduce the workload and improve the nurse work efficiency.
