The patient's crrt machine alarmed for general system failure and per the instructions on the screen the blood was returned manually with the hand crank.After blood return was complete, the bedside nurse attempted to disconnect the line but met resistance.Another nurse tried as well and they were then able to disconnect the line however the internal part of the return tubing broke off inside the patient's dialysis catheter (return lumen).The line was clamped at the time this happened so no part of the tubing could have entered the patient.The patient's physician was notified immediately and they decided to pull the line.The patient was on an argatroban drip so it was held at this time and the physicians said they would order the line to removed in 2 hours with plans to replace the line overnight.Fda safety report id# (b)(4).
