TECHNIQUE OF CHRONIC INTRAVASCULAR CATHETERIZATION FOR MONITORING HEMODYNAMIC AND LABORATORY VALUES IN CONSCIOUS SWINE

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