Abstract
Rinsing rat femoral arteries with various fluids in experimental conditions similar to those in clinical practice was found to have deleterious effects on the intimal and medial layers of the vessels. No statistically significant difference was found between the effects of Ringer’s lactate and normal saline. Heparinized saline produced significantly less damage to the medial layer and less platelet cell deposition. Lignocaine 2% was found to be extremely damaging to the whole vessel wall, and highly thrombogenic. Nevertheless, all the arteries in each group remained patent 4 days after rinsing.
