A user facility registered nurse (rn) reported that a combi set blood leak occurred immediately at the beginning of a patient¿s hemodialysis (hd) treatment.Upon follow up, it was reported that a faint hissing noise was heard, which sounded ¿like air leaking out of a flat tire¿.In addition, blood droplets were observed ¿bubbling up¿ from the top of the venous chamber, where the transducer line connects.The leak was reportedly coming from this connection.No leaking occurred during the priming, and all connections were reportedly tightened properly.The rn stated there were no machine alarms.The patient was dialyzing on a fresenius 2008t hd machine, and was utilizing an optiflux dialyzer.After the blood leak was noted, the treatment was halted.The patient¿s blood was not returned; estimated blood loss (ebl) was approximately 250 ml.The rn confirmed there was no patient injury, no adverse effects were experienced, and no medical intervention was required as a result of the reported event.The patient was able to complete treatment after being re-setup with new supplies on the same machine.The combi set bloodlines were discarded after the event, and therefore, the lot number for the device could not be provided.No sample available for evaluation.
