输液拔针后棉签倒置按压方法的临床研究

目的 探讨静脉输液后采用棉签倒置按压方法避免血液污染和减少出血、淤血的效果.方法 将356例患者分为实验组170例和对照组186例.实验组拔针前,左手将棉签倒置置于皮肤穿刺点上,左手拇指置于棉杆与棉签头交接处的棉杆端,拔针后的瞬间即下压穿刺点;对照组拔针后立即用左手将棉签覆盖皮肤穿刺处及上方血管,同时用拇指沿血管纵向按压;观察并记录出血、淤血情况.结果实验组和对照组出血率和淤血率比较差异有统计学意义,P<0.01.结论 棉签倒置按压法可以减少出血和淤血,并能避免血液污染.

Clinical study on inversely pressing method with cotton stick after extraction of infusion needle

Objective To evaluated the clinical significance of inversely pressing method with cotton stick after extraction of infusion needle to avoid blood contamination,hemorrhage and stagnation.Methods We randomized 356 patients into the experiment group(170 cases)and the control group(186cases).In the experiment group we put the cotton stick inversely on the puncture point and press the point immediately after extraction of the needle with the left thumb.In the control group we put cotton stick on puncture point and proximal vessel after extraction.The conditions of hemorrhage and stagnation were recorded.Results The hemorrhage rate and stagnation rate in the two groups were statistically different (P<0.01).Conclusion To inversely put eotton stick on the puncture point after extraction of infusion needle could lessen hemorrhage and stagnation at the puncture point and avoid contamination.
