A simple technique for the frequent intravenous infusion of fluid without heparin into the rabbit.
A technique is described for the daily intravenous injection over 16 weeks in the rabbit. The system consists of a Teflon cannula passed down the external jugular vein with the tip in the superior vena cava. The cannula is joined at the point of entry to the jugular vein to a length of silicon rubber tubing, which is then passed subcutaneously to the forehead. The silicon tubing is terminated on a Luer needle hub, which is held in a simple Perspex plate secured subcutaneously between the rabbit's ears. The Luer hub is covered with a replaceable rubber cap through which injections may be made. With this system cannulae were maintained patent for 16 weeks by flushing once a day with Hanks' balanced salt solution, pH 7-4.
