自然垂降生理盐水柱法经PICC引导腔内心电图的应用研究

[摘要] Abstract：Objective To evaluate the application of flowchart of normal saline column by gravity drip via peripherally inserted central catheter(PICC)to guide intracavitary electrocardiograms(ECG). Methods  Totally 100 cancer patients undergoing chemotherapy were assigned to the observation group(n=50)and the control group(n=50)according to different methods for PICC tip location. Patients in the control group received chest X-ray to guide the tip location after ultrasound-guided PICC catheterization. The flowchart of normal saline column by gravity drip via PICC to guide intracavitary electrocardiograms was adopted in the observation group. Results  The PICC tip was located properly(lower 1/3 of superior vena cava)in all 100 patients. The proportion of patients with optimum location of PICC tip was higher in the observation group than that of controls(optimum location). Conclusion   Flowchart of normal saline column by gravity drip via PICC to guide intracavitary ECG shows a better efficacy in PICC catheterization, which is advantaged to locating the PICC tip.
