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], p < 0.00001). Total complications and phlebitis events decreased in the IC-ECG group compared with the landmark group. The mean procedure time, thrombogenesis, infection, and arrhythmia in the IC-ECG group are not statistically significant compared with the landmark group. Trial-sequential analysis (TSA) of the results indicate that sufficient events had been observed in the outcomes in success rate on first attempt, overall successful rate, total complications, phlebitis events, and infection events.
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).

01:28Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
