指甲压迫定位法在新生儿桡动脉穿刺中的应用

The application of nail pressure positioning method in neonatal radial artery puncture

目的:探讨指甲压迫定位法在新生儿桡动脉穿刺采血中的应用效果。方法:选取2015年3月至6月的100例需采集血液标本的新生儿为研究对象,随机分为观察组和对照组,观察组采用指甲压迫定位法,对照组采用传统的触摸定位法,比较两组桡动脉穿刺采血的采血时间、皮下血肿发生率和一次性穿刺成功率。结果:观察组的一次性穿刺成功率高于对照组(P<0.05);观察组患儿的血肿发生率低于对照组(P<0.05);观察组采血操作时间短于对照组(P<0.05)。结论:指甲压迫定位法的一次性穿刺成功率高,血肿发生率低,采血操作时间短,能够减轻患儿的痛苦,是一种安全可靠、简单易行的桡动脉定位方法,值得在临床推广应用。

Objective：To explore the application effect of nail pressure positioning method in neonatal radial artery puncture blood collection. Methods： One hundred newborns were collected from March to June 2015 and randomly divided into two groups. Babies in the observation group were punctured by the nail pressure positioning, and those in the control group by radial touching. The blood collection time, the rate of hematoma and the success rate of both groups were compared. Results： As for the observation group, the time of blood sampling was shorter; the rate of hema- toma was lower, and the success rate of the one - time puncture was higher. The method of hall pressure positioning is more effective than the touching method. The difference was statistically significant （ P 〈 0.05 ）. Conclusion：The nail pressure positioning can reduce the children＇s pain caused by repeated puncture, because of the advantages such as accurate positioning, simple operating and high success rate of one - time punc- ture. Thus, it is a safe and reliable method worth clinical popularization.
