Abstract:
Objective To investigate the accuracy and safety of using normal saline as a medium to guide the catheter lumen to assist the localization of the catheter tip. Methods This study included the patients with hematological malignancies in our fully implantable venous port. We enrolled 105 patients from January 2014 to December 2015 as control group, and 220 patients from January 2016 to June 2017 as the experimental group. The control group used the traditional fully implantable venous port after the chest X slice to determine the location of the catheter tip. The experimental group used the intracavitary electrocardiogram location technology to assist the complete implantable venous port catheter tip positioning catheter, then chest X film. Results No catheterization occurred in all the patients. The rate of catheter placement was 100％. In the experimental group, 179 patients (81.36％) had the best placement of catheter tip (i.e., superior vena cava right atrium junction, CAJ), and 35 patients (52.38％) in the control group had the best placement of catheter tip. The proportion of the catheter tip located in the best position (the superior vena cava auricular commissure and CAJ) in the experimental group was higher than that in the control group (χ2=29.615, P < 0.05). Conclusions By the injection of saline guided endocardial mapping real-time monitoring of totally implantable venous transfusion port catheter tip position, can guide the surgeon to grasp the real-time operational direction of totally implantable venous transfusion port catheter tip, accurately positioning the catheter tip position, improve the surgical success rate, worthy of clinical use.
