目的

观察点按新人迎穴预防经外周中心静脉置管（PICC）患者血管痉挛的效果。

方法

选择2013年5月至12月威海市立医院收治的符合入选标准的179例患者，用随机数字法分为观察组90例和对照组89例。对照组置管中多与患者进行沟通；观察组给予点按新人迎穴。两组置管时疼痛评分比较采用t检验，置管时静脉痉挛和静脉炎发生率比较采用χ²检验，以P＜0.05有统计学意义。

结果

观察组置管静脉痉挛发生率13.3%（12/90），对照组为28.1%（25/89），观察组低于对照组，且差异有统计学意义（χ²=5.94，P＜0.05）；观察组静脉炎发生率为4.4%（4/90），对照组为16.9%（15/89），观察组低于对照组，且差异有统计学意义（χ²=7.26，P＜0.05）；观察组置管时疼痛评分为（4.81±1.24）分，对照组为（13.64±1.52）分，观察组低于对照组，且差异有统计学意义（t=42.61，P＜0.01）。

结论

点按新人迎穴能有效预防PICC置管患者血管痉挛，减轻患者疼痛，降低静脉炎发生率。

Objective

To observe effects of pressing XinRenYingXue on the prevention of vascular spasm in patients with peripheral inserted central catheter（PICC）.

Methods

A total of 179 patients who selected from Weihai Municipcal Hospital ranging from May to December 2013 and met the inclusion criteria were randomly divided into observation group（n=90）and control group（n=89）.During catheterization，observation group were pressed on their XinRenYingXue，while control group were only given more communication.Catheterization pain score was analyzed with t-test，and vascular spasm incidence rate and phlebitis incidence rate were analyzed withχ² test.P＜0.05 was considered to be statistically significant.

Results

The vascular spasm incidence rate was（13.3%，12/90）in observation group，which was significantly lower than that of control group（28.1%，25/89，χ²=5.94，P＜0.05）.The phlebitis incidence rate was（4.4%，4/90）in observation group，which was significantly lower than that of control group（16.9%，15/89，χ²=7.26，P＜0.05）.The pain score was（4.81±1.24）in observation group，which was significantly lower than that of control group（13.64±1.52，t=42.61，P＜0.01）.

Conclusion

Results suggest that pressing XinRenYingXue can effectively prevent vascular spasm，reduce pain and decrease phlebitis incidence rate in PICCpatients.
