Clinical Trial Controlled Clinical Trial
Uncomplicated central vein catheterization of high risk patients with real time ultrasound guidance.
Internal jugular vein cannulation has become a routine and clinically important aspect of medical care of critically ill patients. The landmark guided technique usually affords rapid and easy vascular access, but is not always successful and may be complicated by arterial puncture, hematoma, or pneumothorax. Some categories of patients, in particular patients with no external landmarks and patients with coagulopathies, appear to be at an increased risk of complications. ⋯ In particular the 13 cannulations performed in 12 high risk patients were all successful at the first attempt, with no complications. In the overall population successful cannulations improved from 80% to 100%, first attempt success from 20% to 87% and carotid punctures decreased from 33% to 3.2%. Our results confirm that ultrasound guided cannulation of the internal jugular vein allows safer operation in high risk patients or when access problems are anticipated.
