Event or Problem Description
A registered nurse (rn) /clinical coordinator (cc) from a user facility reported that a combiset blood leak occurred during a patient¿s hemodialysis (hd) treatment.The cc said an air detector message went off about one and a half hours into the treatment.The technician operating the machine could not clear the alarm, so they decided to return the patient¿s blood and re-string the machine.As the patient¿s blood was being reinfused, the technician noticed blood on the machine and saw that it was coming from the heparin line t-connector, just below the blood pump on the arterial side.The blood was leaking from the connection point of the main line to the t-connector.As the supplies were being removed, the main line completely separated from the connector.The cc said the patient¿s blood had already been returned and blood loss from the leak was minimal.Estimated blood loss (ebl) from the leak was less than 5 ml.Prior to the leak, there were no known loose connections on the combiset lines.The cc said there were no leaks noticed during the priming phase.In addition, there were no changes or disruptions in pressure that could have contributed to the failure.The cc confirmed there was no patient serious injury, no adverse effects were experienced, and no medical intervention was required as a result of the reported event.The patient completed their treatment after being re-setup with new supplies on the same machine.The complaint device was not available to be returned for evaluation as it was reportedly discarded.
