Bleeding occurred from the wire lumen port (proximal luer) after it broke off, 5 hours or so into infusion in the icu.Patient had a ct scan (time of scan not specified).No infusion of blood was required.The guidewire port is only used to place the catheter in the desired location; then the wire is removed.The lumen of the guidewire is 0.018 (18 thousandths) of an inch in diameter i.E.Very small and venous back pressure into this lumen would be < 10 mm hg.Corrective action resulted in a design change to the proximal luer to make it more flexible to prevent breakage for the entire product line of catheters.
