Physiologic Aspects of Porcine Hemorrhage. I. A Vascular Catheter for Chronic Implantation in Swine.
Abstract
In this study, a catheter system developed for chronic implantation in dogs was modified and implanted into the cardiovascular system of 50 pigs. Under halothane anesthesia, Silastic and Tygon combination catheters were placed in the ascending aorta via the left common carotid artery of 41 animals; ten of these animals also received a combination catheter placed in the right ventricle via the left internal jugular vein. Nine animals received carotid arterial catheters constructed entirely of Silastic. The catheters were tunneled subcutaneously, exited through the skin on the dorsum of the neck, and secured with a Velcro patch. The Velcro patch on the dorsal neck also promoted cleanliness of the exit site, protected the exteriorized catheters from being dislodged by the animal, and provided ready access to the cardiovascular system without need for excessive physical or chemical restraint.
