Positioning of the Central Venous Catheter for Hemodialysis Using Wireless Intracavitary ECG: A Case Series and Narrative Review of the Literature.

This study aimed to evaluate the practicality and feasibility of using intracavitary electrocardiography to confirm the proper placement of a central venous catheter for hemodialysis. Central venous catheters are typically placed using an echo-guided technique based on anatomical landmarks, followed by X-ray confirmation. Anesthesiology guidelines recommend evaluating the intracavitary electrocardiogram during the procedure to verify the correct CVC placement. This study involved 11 patients without rhythm disturbances, in whom a central venous catheter was placed in the right internal jugular vein at our institute in 2024. The patient's electrocardiogram was analyzed using the MAGELLANO (Italy) device to identify changes in the P wave or QRS complex, which confirmed the CVC's correct placement at the right cavoatrial junction. Thoracic ultrasound was used to identify the right internal jugular vein and exclude iatrogenic pneumothorax. A subsequent chest X-ray was performed to further confirm the correct placement. In addition, a non-systematic review of the most recent literature on this topic was conducted using the Database PubMed-United States National Library of Medicine. Chest X-ray consistently verified the correct placements identified by ECG-IC, with no post-procedure complications. ECG-IC is a straightforward, viable, and cost-effective technique with high sensitivity when administered by properly trained professionals. This approach, combining ultrasound-guided CVC placement in the right internal jugular vein and intracavitary ECG monitoring, can omit X-ray control in more than 90% of cases.
