Abstract
In human and small animal intensive care medicine percutaneous sheath introducer (PSI) sets are commonly used for repeated insertion of an arterial or a venous catheter with only one vascular puncture.
We used PSI for chronic catheterization of swine with a Swan-Ganz thermodilution catheter via a surgically exposed external jugular vein. In this way we were able to change defective catheters or correct the position of the catheter tip without renewed surgical intervention.
