Meta-Analysis of Atrial Electro-Gram Applied to PICC Catheter Tip Positioning

摘要

Objective: Assess the location effect of the atrial electrogram in the PICC catheter tip. Method: Make online research in the CNKI, CBM, Wanfang, VIP, Database, Cochrane Library, JBI Library, PubMed, Ovid, Springer, Web of science, MEDLINE database to collect the randomized controlled trial data of using the atrial electrogram to locate the PICC catheter tip. When making the online research, only the data to November 20, 2016 can be searched out. Two researchers independently select the literature and information, make quality assessment, and then use the RevMan 5.2 software to make Meta analysis. Result: 16 random tests are done. The Meta analysis results show that compared with the traditional X ray chest radiograph location method, the atrial electrogram can increase the accuracy rate of the location of the catheter tip [RR = 1.13, 95%CI (1.07, 1.19), P < 0.00001]; it can decrease the incidence rate of related complications [RR = 0.37, 95%CI (0.21, 0.66), P < 0.0008]; and it can save the catheter placing time [RR = − 12.56, 95%CI ( − 18.56, − 6.57), P < 0.0001]. Conclusion: The atrial electrogram can increase the accuracy rate of the location of the catheter tip, decrease the incidence rate of related complications and save the catheter placing time. Therefore, it is worthy of clinical application.
