Clinical application of atrial ECG guided the three directional valve PICC tip positioning method

Abstract

Objective To investigate the clinical application effects of atrial electrocardiogram guided the three directional valve PICC tip localization method. Methods After application of instant location technology of arterial electronic monitoring in the experimental group, the patients received X ray examination on chest, and double check the top catheter location of PICC; the control group utilized routine location method to ensure the top catheter position, which inserted the fitted length of tube (from the puncture position to right chest lock joint then to the third intercostal space) then sent to do X ray examination to ensure the top catheter position. The incidences of location accuracy, operation time and cost were compared between two groups. Results The accuracy of locations were 98.7% in the experimental group and 91.0% in the control group (χ2=8.01, P 0.05). Conclusions The position control of atrial electrocardiogram technology was applied to place PICC, which can judge catheter top position promptly and accurately, improve the accuracy rate of PICC catheter positioning effectively, and increase work efficiency.
