Study on the application of two intracavity electrocardiogram localization techniques in Dacron-cuffed double lumen hemodialysis catheter

ObjectiveTo explore the application of two intracavity electrocardiogram localization techniques in Dacron-cuffed double lumen hemodialysis catheter.

MethodsSixty patients implanted with Dacron-cuffed double lumen hemodialysis catheter were selected and randomly divided into 0.9% sodium chloride solution-guided lumen electrocardiogram group and wire-guided lumen electrocardiogram group(30 cases in each group).The characteristic P-wave stability, catheter tip in place rate, medical staffs′ satisfaction, operation time and puncture point infection rate of the two methods were compared.

ResultsStable intracavity electrocardiogram during the implantation of Dacron-cuffed double lumen hemodialysis catheter was exported in all patients, with characteristic P-wave, and the catheter tip was located at the level of right atrial entrance.The stability ratio of characteristic P-wave in wire-guided lumen electrocardiogram group was higher than that in 0.9% sodium chloride solution-guided lumen electrocardiogram group, but the difference was not statistically significant(P>0.05).The operation time in 0.9% sodium chloride solution-guided lumen electrocardiogram group was significantly higher than that in wire-guided lumen electrocardiogram group(P < 0.01).The satisfaction of doctors and nurses in 0.9% sodium chloride solution-guided lumen electrocardiogram group was significantly lower than that in wire-guided lumen electrocardiogram group(P < 0.01).There was no infection in the two groups, the difference of which was not statistically significant(P>0.05).

ConclusionsBoth methods can guide the intracavity electrocardiogram.The wire-guided intracavity electrocardiogram can obtain characteristic P-wave more stably, the process is more convenient, and the satisfaction degree of medical staffs is higher.
