title: Real-time ultrasound and endocavitary electrocardiography for venous catheter placement.
abstract: The authors report on their experience with internal jugular vein catheterization with temporary and tunnelled cuffed hemodialysis catheters in 527 patients from 1991 to 2001, using ultrasound guidance and monitoring of catheter placement by endocavitary electrocardiography. The incidence of successful puncture and cannulation using ultrasound was 99.62%. The majority of patients had catheters inserted on the first pass (93%) and fewer attempts were required (range, 2 to 5). In the first year of the procedure in 1991, we observed two cases of accidental puncture of the carotid artery because of an error in ultrasound localization of the neck vessel. Arrhythmias were not observed during this procedure. Right atrial electrocardiography was successful on 504 occasions (96.83%), and correct catheter placement was confirmed by plain chest-X-ray in the first 100 patients. The results confirm that real-time ultrasound guidance for catheter insertion is superior to tradi-tional techniques relying on anatomic landmarks and should be adopted as the standard of care. Ultrasound guidance and EC-ECG improves both the success and the safety of internal jugular catheter insertion. The authors propose that EC-ECG be validated as a technique in compliance with recent Food and Drug Ad-ministration guidelines regarding the location of central venous catheter tips.
