腔内心电图在PICC置管尖端定位中的应用价值

Application value of intracavitary electrogram in the positioning of PICC catheter tip

目的探讨腔内心电图在PICC置管尖端定位中的应用价值。方法选择2019年4月—2021年7月医院进行PICC置管的患者310例为研究对象,按照组间基本资料具有可比性的原则分为观察组和对照组,每组155例。观察组采用超声+体外测量+腔内心电图+X线定位,对照组采用超声+体外测量+X线定位。所有患者置管后均行胸部X线确定导管尖端位置。结果观察组患者PICC置管后一次性到位率高于对照组(P<0.05),观察组PICC置管一次性到位尖端位置优于对照组(P<0.05),观察组患者护理满意度高于对照组(P<0.05)。结论腔内心电图定位可提高一次性到位率和尖端最佳到位率,减少患者X线辐射机会,减轻护士工作量,提高患者满意度。

Objective To explore the application value of intracavitary electrogram in the positioning of PICC catheter tip.Methods A total of 310 patients who underwent PICC catheterization in the hospital from April 2019to July 2021 were selected as the study objects,and they were divided into an observation group and a control group according to the principle of comparability of basic data between groups,with 155 cases in each group.The observation group was treated with ultrasound+in vitro measurement+intracavitary electrogram+X-ray positioning,while the control group was treated with ultrasound+in vitro measurement+X-ray positioning.All patients underwent chest X-ray to determine the position of the catheter tip after catheterization.Results The rate of one-time placement of PICC catheter in the observation group was higher than that in the control group(P<0.05).The position of the one-time placement of the PICC catheter in the observation group was better than that in the control group(P<0.05).The nursing satisfaction of patients in the observation group was higher than that in the control group(P<0.05).Conclusions Intracavitary electrocardiographic positioning can improve the one-time delivery rate and the best tip delivery rate,reduce the chance of X-ray radiation for patients,reduce the workload of nurses,and improve patient satisfaction.
