Aim Of The Study:
The Authors analyzed the results of 120 central venous catheterisms of internal jugular vein performed by eco-color-Doppler from January 2000 to December 2004 in obese patients candidated to bariatric surgery.
Results:
As the considerable adiposity and post-operation necessities, this procedure has been very useful. The average performing time was 10 minutes, 95.8% of success and 4.2% of impossibility (thrombosis internal jugular vein bilateral).
Conclusions:
The eco-color-Doppler guide CVC is a safe procedure with short performing time, low rate of failures and complications, and high rate success. It was very helpful in obese patients candidated to bariatric operation, allowing a comfortable and easy venous access, as well as the administration of liquids otherwise administered with difficulty by peripheral way, correlated to corporal weight in qualitative and quantitative terms, such at improve the process of post-operative recovery.
