生理盐水持续加压冲洗在中心静脉压监测中的应用

Application of continuous pressure washing with normal saline in central venous pressure monitoring

目的探讨持续生理盐水加压冲洗在维持中心静脉压(CVP)监测中的应用。方法 110例行CVP监测的患者分为实验组和对照组,各55例。对照组使用常规肝素盐水持续加压冲管,实验组使用生理盐水持续加压冲洗测压管路。记录2组完成CVP监测情况,比较2组测压管堵塞情况。结果实验组完成CVP监测54例,对照组完成49例。实验组中心静脉导管测压腔堵管率为7.1%(4/54),对照组中心静脉导管测压腔堵管率4.1%(2/49),2组比较差异无统计学意义(P>0.05)。结论持续生理盐水加压冲洗与肝素冲洗效果相似,且其适用广泛,操作简便。

Objective To investigate the effect of continuous pressure washing with normal saline in central venous pressure （CVP） monitoring. Methods A total of 110 patients undergo-ing CVP monitoring were assigned to the study group and the control group, with 55 cases in each group. The control group was given heparin saline solution for washing catheter, while the study group was given normal saline solution for continuous pressure washing catheter. The CVP moni-toring condition and incidence of catheter obstruction were observed. Results There were 54 pa-tients in the study group and 49 patients in the control group accomplished the CVP monitoring. The incidence of catheter obstruction was 7.1% （4/54） in the study group and was 4.1 % （2/49） in the control group, with no significant difference （P 〉0. 05）. Conclusion Normal saline solu-tion shows similar efficacy as the heparin saline solution in continuous pressure washing catheter, and with an advantage of easy operation.
