Abstract:

Objective To explore the optimal method for guiding totally implantable access port via upper arms using intracavitary electrocardiogram.Methods One hundred and ten patients were enrolled and randomly divided into the guide wire conducting group and the normal saline conducting group. Occurrence rate of P wave with characteristics,stability of electrocardiogram,accuracy of catheter tip position,satisfaction of medical staff and length of operation were compared between two groups.Results The intracavitary electrocardiograms were caught in all patients and were stable,the catheter tip position was located in the inferior 1/3 segment of the superior vena cava. The occurrence rate of P wave with characteristics in the guide wire conducting group was significantly higher than that in the normal saline conducting group（P=0.028）. The satisfaction of medical staff in the normal saline conducting group was significantly higher,and length of operation in the normal saline conducting group was significantly shorter than the guide wire conducting group（P<0.001）.Conclusion Both methods can obtain intracavitary electrocardiogram,P wave with characteristic can be easily obtained in the guide wire conducting group,whereas the operation process is more convenient in the normal saline conducting group.
