摘要
目的探讨无偿献血后两种不同按压方法对皮下瘀血发生率的影响作用,以选择最佳的按压方法。方法对160例无偿献血者采用随机配对方法分为两组,对照组采用传统的屈肘棉签横压迫法,实验组采用伸肘棉签直压迫法。结果两组按压总有效率,实验组为91.6%,对照组为76.4%;瘀血直径<1cm,实验组为5.8%,对照组为11.6%;瘀血直径>1cm,实验组为2.6%,对照组为9.1%。结果伸肘棉签直压迫法的皮下瘀血发生率明显少于屈肘棉签横压迫法,两组比较有统计学差异(P<0.05)。结论伸肘棉签直压迫法能有效地减少皮下瘀血的发生,是无偿献血后比较理想的按压方法。
Objective To study the effect of two different local pressing methods on the ecchymoma after drawing blood in vein. Methods 160 blood donor were divided into the experimental group with cotton bud verti- cal pressing and the control group with cotton bud across pressing. Results The total effective rate was 91.6% in the experimental group and 76. 4% in the control group. The diameter of congestion beyond 1 cm was 2. 6% in the experimental group and 9. 1% in the control group. Conclusion The cotton bud vertical pressing was a suitable choice of pressure-messages after drawing blood in vein and can effectively reduce hypodermic hemorrhage.
