改良留置针穿刺法在先天性心脏病合并肺炎患儿中的应用

Application of improved indwelling needle puncture on infant patients with congenital heart disease complicated with pneumonia

目的：探讨改良留置针穿刺法在提高先天性心脏病并肺炎患儿穿刺中一次成功率中的效果。方法选择在儿童重症病房住院的先天性心脏病合并肺炎的患儿120例,按完全随机法分为观察组与对照组,各60例。观察组用改良的穿刺方法,对照组用常规的穿刺方法,比较两组一次穿刺成功率。结果观察组一次穿刺成功47例,对照组一次成功34例,两组一次穿刺成功率比较,差异有统计学意义（χ2=6.469,P＜0.05）。结论对先天性心脏病合并肺炎的患儿穿刺静脉留置针时采用改良后的穿刺法可以提高一次穿刺成功率,值得在儿科护理工作中推广。

Objective To investigate the application of improved indwelling needle puncture on infants of congenital heart disease complicated with pneumonia, and account the rate of successful puncture in one time. Methods A total of 120 congenital heart disease complicated with pneumonia infants in the pediatric intensive care unit were selected and randomly divided into observation group and control group with 60 cases in each. Improved puncture method was used in the observation group and conventional puncture method in the control group. The number of one-time successful puncture cases was compared in two groups. Results The number of one-time successful puncture was 47 with 13 unsuccessful one-time puncture in the observation group and 34 comparing with 26 cases in the control group （χ2 = 6. 469,P 〈 0. 05）. Conclusions Using the improved puncture method could improve one-time success rate in the infants of congenital heart disease complicated with pneumonia, it is worthy to popularize in pediatric nursing.
