The present invention provides an apparatus and a method for administering medicants, specifically anesthesia, to a catheterized patient. An administration tube is provided in longitudinal connection with an aspiration tube. The administration tube preferably has plural fenestrations provided along its length to administer anesthesia to the areas surrounding the catheter. The aspiration tube has at least one opening to aspire fluids from a patient. A preferred usage is for the interpleural space, wherein fluids are aspired through a series of aspiration apertures on the aspiration tube, and the surrounding tissues and intercostal nerves are anesthetized through the fenestrations to alleviate pain and discomfort commonly associated with catheters.
