Hello, I have come across a practice where the nurse is drawing labs from the trifuse (manifold) extension set that is connected to the patient's central line. They state that by taking the blood from one of the lumen of the trifuse's, they do not have to disconnect the tubing from the patient's line, that would render it a 24 hour tubing change due to the tubing disconnection. In the case of a blood culture, they change the needleless access device from the trifuse first, then draw the blood. Has anyone else seen this practice of drawing from the trifuse instead of disconnecting the tubing and drawing directly from the patient's line? Thanks!
