A pt in (b)(6) was undergoing a dialysis session which included a cartridge bloodline.Approximately an hour into treatment, the patient's venous and arterial pressures dropped and did not change despite the nurse performing the diaphragm repositioning procedure.Treatment continued for another hour and the venous side of the circuit clotted.The pt had an estimated blood loss of 200 ml when only a portion of the blood in the extracorporeal circuit was returned.Following rinse back, the pt developed severe dorsal pain and the pt was transferred to the emergency room.The pt was admitted to the hosp with a diagnosis of hemolysis which was confirmed with a peripheral blood smear, haptoglobin, and blood schistocytes.The patient's hemoglobin dropped to 50 g/dl and 2 units of packed red blood cells (prbcs) were given.The pt was discharged from the hosp one week later.
