静脉输液拔针后不同按压方法的效果观察

Research on the effect of the different method of pressing blood vessel in intravenous injection after withdrawing the needle

目的比较4指按压法和握式4指按压法的止血效果，探讨静脉输液拔针后最佳的按压止血方法和病人容易接受的方法。方法采用自身对照法，对194例病人分别用4指按压法和握式4指按压法进行静脉输液拔针后按压效果的观察，评价皮肤出血、皮下淤血的发生情况，了解病人更容易接受哪一种按压方法。结果4指按压法与握式4指按压法比较，出血发生率分别为10．31％和0．52％，淤血发生率分别为9．28％和0．52％，均有统计学意义（P〈0．01）。病人更喜欢握式4指按压法。结论静脉输液拔针后使用握式4指按压法能更效地减少皮血出血及皮下淤血的发生皮情况，且病人乐于接受。

Objective To explore which method is more effective and easily accepted by patients through contrasting the method of pressing blood vessel with four fingers and the method of pressing blood vessel with four fingers holding the hand. Methods In this study, to learn which method is better accepted by patients, 194 cases were observed by self-control study after withdrawing the needle. The occurrence of bleeding and petechia was evaluated. Results In the method of pressing blood vessel with four fingers and the method of pressing blood vessel with four fingers holding the hand, the occurrence rates of bleeding were 10.31% and 0. 52% , and the occurrence rates of petechia were 9.28% and 0.52% , respectively. There was a significant difference between the occurrences of bleeding and petechia （P 〈 0. 01 ）. The patients preferred to the method of pressing blood vessel with four fingers holding the hand. Conclusions Adopting the method of pressing blood vessel with four fingers after withdrawing the needle could reduce the occurrence of bleeding and petechia more effectively and is better accepted by patients.
