ACUTE LINE -
Noun: A central venous catheter that is inserted into either a vein located under your collarbone in the neck or in the groin. The tip of the catheter is passed along the vein until it is positioned in a larger vein called the superior vena cava if under the collarbone or the inferior vena cava if placed in the groin. Both these sites return blood back to the heart. The Acute Line is made from polyurethane and is designed to stay in place for periods extending from one to six weeks. It is secured in position with two stitches that stay in place until the device is removed. Although there may be some anxiety about having this done, very little discomfort should be felt. (I found it about 1/4 the unpleasantness of the Bone Marrow trephine ).
