腔内心电图在PICC尖端定位中的临床应用价值研究

Clinical application value of intracavity electrogram in PICC tip location

目的:探讨PICC尖端定位中采用腔内心电图的临床疗效。方法:88例PICC置管患者运用数表法将患者分成实验组与对比组,实验组的44例患者采取超声结合腔内心电图定位法实施定位,对比组44例患者仅仅采取超声实施定位。结果:实验组患者的尖端异位率明显低于对比组,差异具有统计学意义(P<0.05)。结论:在临床PICC尖端中采取超声结合腔内心电图展开定位,可使得尖端到位的准确性得到显著提高,且具有更高的定位安全性。

Objective:To study and analyze the clinical efficacy of intracavitary electrocardiogram (ECG) in PICC tip positioning.Methods:this study was conducted on 88 patients with PICC catheterization in hospital.The patients were divided into experimental group and control group by digital table method.44 patients in experimental group were positioned by ultrasound combined with intracavitary electrocardiogram,while those in control group were only positioned by ultrasound.Results:the rate of apical ectopic was significantly lower in the experimental group than in the control group (P<0.05).Conclusion:Ultrasound combined with intracavitary electrocardiogram can improve the accuracy and safety of PICC tip positioning.
