Objective:To analyze the effect of evidence-based practice combined with atrial electrocardiogram (ECG) monitoring on the three-dimensional valve PICC tip localization. Methods:100 cases of patients with three-dimensional valve PICC admitted during January 2016 to October 2017 in our department of oncology were divided into observation group and control group according to random number table, 50 in each group. The control group was given routine nursing intervention with conventional surface location method for PICC tip positioning, while the observation group was given evidence-based practice with atrial endocardial monitoring of real-time positioning technology for PICC tip positioning. PICC catheter positioning accuracy, positioning time, cost of catheterization and patient satisfaction with caregivers were compared between the two groups. Results:The PICC catheterization accuracy of the observation group was as high as 98.00%, significantly higher than that of the control group of 86.00%(χ2=4.891 3,P=0.027 0).The stability of electrocardiogram waveform in the observation group was 90.00%, which was significantly higher than 74.00% in the control group(χ2=4.336 0,P=0.037 3). Among the 5 patients with unstable ECG waveform in observation group, there were 3 cases of drift wave, 1 case of coarse wave and 1 case of wave discernment. The time spent in the observation group was (4.69±3.97) min and the localization cost was (5.94±4.61) Yuan, which were respectively significantly lower than those in the control group (7.86±4.05) min and (41.72±8.68) Yuan(t=3.952 4,P=0.000 1;t=25.742 4,P=0.000 0),respectively. The score of nursing satisfaction in the observation group was (9.61±0.25) points, which was significantly higher than that of the control group (7.12±0.19) points(χ2=56.072 0, P=0.000 0).Conclusion:Evidence-based practice combined with atrial electrocardiogram monitoring can significantly improve the three-dimensional valve PICC tip positioning with shorter catheterization time, easier operation, less operating time and cost, thus worthy of recommendation. |
