便携式静脉显影灯在微光输液中的应用

目的 探讨便携式静脉显影灯在微光静脉输液中的应用效果.方法 便利抽样法选取2019年度秋季某部302名学员为研究对象,按随机数表法分为对照组(n=150)和观察组(n=152).对照组按常规方法进行静脉留置针穿刺,观察组使用便携式静脉显影灯辅助进行静脉留置针穿刺.分别在自然光线充足和模拟战场微光场境下,对比两组一针穿刺...

Application of a Portable Intravenous Visualizer in Indwelling Needle Puncture under Faint Light

Objective To explore the efect of a portable intravenous visualizer in intravenous infusion under faint light.Methods In the autumn of 2019,a total of 302 pre selected medical Non commissioned Officers(NCOs)were randomly divided into the control group(n=150)and the observation group(n=152).The control group used conventional intravenous indwelling needle puncture method,while the observation group conducted the punc-ture with the portable intravenous visualizer.The one-time puncture success rate and time of the puncture were compared between using and without using the portable intravenous visualizer under sufficient natural light and battlefield-simulated faint light.Results Under sufficient natural light,with the portable intravenous visualizer the one-time puncture success rate of the observation group didn’t improve significantly(P>0.05),while the time of the puncture of the observation group improved significantly(P<0.05).With the portable intravenous visualizer,both groups'one time puncture success rate and the time of the puneture improved significantly under battlefield-simulated faint light(all P<0.05).Conclusions The application of the portable intravenous visualizer can reduce the time of the puncture in two scenes,improve the one-time puncture success rate under battlefield-simulated faint light,and obviously improve the training effect.
