Pt was on continuous renal replacement therapy (crrt).System was running without issue.At 8 am, rn was doing her assessment and picked up covering of line.While removing the covering, the return line stopcock became disconnected where it joins the catheter to the patient.She quickly reconnected it.No air entered the tubing and there were no untoward complications.The rn asked another nurse to check on the connections -the stopcock and line- and the second rn felt they were both secure.At noon, the patient was being repositioned and the stopcock again became disconnected.The nurse (who had previously checked the connection) quickly reconnected the line.No complications occurred.The patient was repositioned appropriately.The circuit was placed in the recirculate mode and the stopcocks were changed out.
