A special anatomic preparation for teaching central venous catheterization

Catheterization of the subclavian and internal jugular veins is a commonly performed procedure for monitoring the hemodynamic, respiratory, and fluid status of patients as well as for delivery of special potent drugs and nutritive solutions. In inexperienced hands, this procedure can carry significant morbidity. A comprehensive central line placement teaching program has been developed at our institution centered upon an anatomy and catheterization skills workshop. A dedicated anatomic specimen has been prepared to emphasize key anatomical concepts about the subclavian and internal jugular veins. A design with easily reflectable flaps allows quick and simple visualization of needle position after supervised cannulation attempts. Workshop preparation and teaching sessions benefit from close collaboration between anatomists and clinicians. This should help standardize residents' exposure to central venous cannulation techniques and ensure basic procedure skills prior to actual cannulation in patients.
