摘要
目的比较不同的采血技巧及按压方法对皮下淤血和针头滴血的影响。方法实验组在采集血标本的最后一个管时即松开止血带,拔针后瞩患者立即用大拇指适力持续按压5-10分钟,使皮肤针眼和血管针眼同时按压,胳膊伸直不揉不打弯。对照组在采集血标本的最后一个真空管时,采足所需血量后（即无血液流入真空管）即松开止血带。按照常规的按压方法按压。结果实验组穿刺部位皮下淤血明显低于对照组（P〈0.05）,针头滴血也明显低于对照组（P〈0.05）。结论大拇指按压法及提前松止血带能有效减少皮下瘀血和针头滴血现象的发生。
Objective To compare the impact of different blood sampling techniques and press methods on ecchymoma and needle drop of blood.Methods The experimental group loose tourniquet after the last tube.Told patients to press skin needle eye and vessel needle eye by thumb after pulling needle.The control group loose tourniquet after sampling enough blood volume.Results The ecchymoma of the puncture site of experimental group were obviously lower than the control group.The needle drop of blood were also obviously lower than the control group.Conclusion Thumb pressure and loose tourniquet ahead of time can effectively reduce phenomenon of ecchymoma and needle drop of blood.
