有创血压监测中生理盐水持续加压冲洗的应用研究

Applied Research on Continuous Pressurized Irrigation of Saline in Invasive Blood Pressure Monitoring

目的分析有创血压监测中生理盐水持续加压冲洗的应用效果。方法 2016年9月—2018年5月,于云南省昆明市第二人民医院麻醉科麻醉手术中行有创血压监测的患者中选取300例,随机分为甲、乙、丙三组,各100例。甲组采用生理盐水行持续加压冲洗,乙组采用2.5U/ml肝素行持续加压冲洗,丙组则采用5U/ml肝素行持续加压冲洗,经桡动脉穿刺置管成功之后,比较三组动脉置管通畅情况以及穿刺部位出血、动脉炎等并发症发生情况。结果甲组导管通畅率为95%(95/100),乙组为94%(94/100),丙组为96%(96/100),组间差异无统计学意义(P>0.05);甲组患者穿刺部位出血发生率为0,低于乙组的5%与丙组的8%,组间差异有统计学意义(P<0.05)。结论有创血压监测中生理盐水持续加压冲洗的应用效果显著,有利于减少稀肝素持续冲洗而引起的凝血障碍,将动脉穿刺置管的使用率提高,为患者生命安全提供有效保障。

Objective To analyze the application effect of continuous saline irrigation in invasive blood pressure monitoring.Methods From November 2016 to May 2018,300 patients with invasive blood pressure monitoring were selected from anesthesiology department.They were randomly divided into three groups:group A,group B and group C,100 cases in each group.Group A was treated with normal saline continuous pressure irrigation,group B with 2.5 U/ml heparin continuous pressure irrigation,group C with 5 U/ml heparin continuous pressure irrigation.After the successful placement of the radial artery catheter,arterial catheter patency and complications such as bleeding at the puncture site,and arteritis of three groups were compared.Results The patency rate of catheterization was 95%(95/100)in group A,94%(94/100)in group B and 96%(96/100)in group C(P>0.05).The incidence of puncture site hemorrhage in group A was 0,which was lower than that in group B(5%)and group C(8%).There was significant difference between the two groups(P<0.05).Conclusion The application of continuous saline irrigation in the invasive blood pressure monitoring is effective,which is beneficial to reduce the coagulation disorder caused by the continuous washing of dilute heparin,improve the utilization rate of the arterial catheter,and provide effective guarantee for the patient’s life safety.
