Abstract
Background:
The intracavitary electrocardiogram (IC-ECG) localization technique has been widely used in peripherally inserted central catheter (PICC) placement. However, the accuracy of IC-ECG on PICC tip localization and complications remains controversial. The purpose of this work is to evaluate the clinical efficacy and safety of IC-ECG on PICC placement.
Materials and Method:
We retrieved randomized control trials from PubMed, Web of Science, Cochrane Library, EMBASE, and CNKI databases published before October 30, 2024. Patients guided by IC-ECG technology or landmark, and then used radiography to confirm the tip position, regardless of age, race, nationality, and region. Interventions other than IC-ECG or landmark were excluded. We used the Cochrane Bias Risk Assessment tools version 2 to evaluate the quality of enrolled trials. The Grading of Recommendations Assessment, Development, and Evaluation Statements online tool was used to determine the certainty of the evidence. The primary outcome was the success rate on the first attempt.
Results:
Sixteen studies involving 6707 PICC patients are included. The results of the meta-analysis indicate that the IC-ECG group has a significantly higher success rate on first attempt of PICC placement (RR = 1.23, 95% CI [1.09–1.37],
Conclusion:
The IC-ECG guided method has a higher success rate on the first attempt and lower total complication for catheter tip localization in PICC placement. IC-ECG may be considered the preferred method for accurate catheter tip placement. (PROSPERO registration number, CRD42023456651).
