While performing cares it was noted that blood was backing up in the blue lumen of patient's uvc.Attempt to flush line normal saline syringe was unsuccessful.Another rn was immediately called to come to the bedside and assess.Before the other rn arrived, all clamps and lines rechecked to make sure all were appropriate and no problems were found.Tpn was changed a few hours prior to noted blood backing up and clamps were double checked immediately after tpn change with 2nd rn.Red tape was applied to clamps of syringes not being infused.The doctor was also at bedside.Other rn attempted to flush the blue lumen without success.Together we flushed the tpn line infusing in the blue lumen to find it was cracked just before the filter and was infusing fluid out of the crack of the tubing.We removed the tubing and placed all fluid to be infused in the remaining white lumen.We also changed the rate to the appropriate rate.Unable to re-create how tubing could have been compromised by clamp.
