ObjectiveTo explore the accuracy and safety of two intracavitary electrocardiographies at different timing combined with extracorporeal measurement for the positioning of peripheral venous catheterization(PICC) tip in tumor patients.
MethodsSixty-four tumor patients undergoing PICC and chemotherapy were selected as the study subjects and divided into intervention group and control group according to the random number method, with 32 cases in each group.Patients in the two groups were implanted with PICC by intracavitary electrocardiography combined with extracorporeal measurement.Patients in the control group underwent X-ray examination within 30 minutes after successful placement of PICC by intracavitary electrocardiography, and patients in the intervention group underwent X-ray examination at 3 hours after successful PICC implantation by intracavitary electrocardiography.The success rate of catheter positioning, patient's satisfaction and the incidence of catheter-related complications within 7 days after catheterization were compared between two intracavitary electrocardiographies at different timing combined with extracorporeal measurement.
ResultsThere was no significant difference in the success rate of one-time catheterization between the two groups(P>0.05).The patient's satisfaction of catheterization in the intervention group was higher than that in the control group (P < 0.05).The incidence of catheter-related complications was 0.00%(0/32) in the intervention group within 7 days after catheterization, which was lower than that of 18.75%(6/32) in the control group (P < 0.05).
ConclusionsIntracavitary electrocardiography positioning can replace X-ray examination at 3 hours after PICC implantation in tumor patients, which does not affect the success rate of one-time catheterization, is helpful to improve patient's satisfaction with catheterization, and reduces the incidence of complications of catheterization.
