腔内心电图定位联合床旁超声在PICC置管中的临床应用

Clinical application of intracavitary electrocardiogram combined with bedside ultrasound in PICC catheterization

目的探讨腔内心电图定位联合床旁超声在PICC置管中的临床应用价值和可行性。方法选取符合标准的PICC患者248例,观察组采用腔内心电图定位联合床旁超声进行PICC置管,对照组采用传统方法进行PICC置管。结果观察组124例中导管尖端到位119例,导管尖端不到位5例,对照组124例中导管尖端到位102例,导管尖端不到位22例,通过两组数据比较,χ~2=12.011,P=0.001,二者具有可比性,有统计学意义。结论腔内心电图定位联合床旁超声进行PICC置管,不仅提高了静脉穿刺的成功率,而且提高了PICC尖端定位的准确率,为降低导管尖端位置的异位率提供了有力保障,该技术具有很大的临床主流应用的潜在趋势。

Objective:To explore the clinical value and feasibility of intracavitary electrocardiogram positioning combined with bedside ultrasound in PICC catheterization.Method:248 patients who met the standard of PICC were selected.The observation group was treated with intracardiac electrocardiogram location combined with bedside ultrasound,and the PICC group was placed in the control group.Result:In the observation group,there were 119 cases of catheter tip,5 cases of catheter tip not in place in 124 cases,124 cases in control group,102 cases of catheter tip in 102 cases,22 cases of catheter tip not in place.Compared with two sets of data,X2 value 12.011,P value 0.001,two were comparable.Conclusion:Intracavitary electrocardiogram location combined with bedside ultrasound for PICC tube can improve the success rate of venipuncture,improve the location effect of PICC tip,and provide a guarantee for reducing the rate of tip ectopia.This method is expected to become the mainstream trend of clinical application.
