Manufacturer Narrative

Clinical investigation: a temporal relationship exists between hd therapy utilizing the optiflux 180nre dialyzer and the serious adverse events of blood loss, hypotension, loss of consciousness, and anxiety which required hospital-based evaluation and monitoring. The reporter stated no defect(s) or damage was observed on the exterior of the optiflux 180nre dialyzer. However, evidence of a dialyzer membrane rupture was confirmed by the visualization of blood in the dialysate compartment. The etiology of the dialyzer membrane rupture, which preempted the events is unknown; therefore, causality cannot firmly be established. However (as reported by the cm), a physician (specialty not provided) deduced the patient became anxious due to the events and lost consciousness. While uncommon, blood leak events are a known potential complication of utilizing optiflux dialyzers during hd therapy. Based on the information available, the optiflux 180nre dialyzer cannot be disassociated from the events. Despite the physician¿s diagnosis of an anxiety attack precipitating the loss of consciousness, and given the lack of treatment records, discharge summary and no returned product for manufacturer evaluation. The optiflux 180nre cannot be excluded from having a possible causal or contributory role in the serious adverse events. The plant investigation is in process. A supplemental mdr will be submitted upon completion of this activity.

Event Description

A user facility clinic manager (cm) reported that an internal dialyzer blood leak occurred at the beginning of a patient¿s hemodialysis (hd) treatment. The blood leak was reportedly visible in the dialysate compartment of the device. The machine, a fresenius 2008t, alarmed appropriately with a blood leak alert. Fresenius bloodlines were also being used. Blood test strips were not used; the cm stated the blood leak was obvious and the use of test strips was not necessary. There was no damage identified on the dialyzer. After the machine alarmed, the treatment was halted. The patient¿s blood was not returned; their estimated blood loss (ebl) was approximately 100 ml. Following the event, the patient became hypotensive and briefly lost consciousness. Cardiopulmonary resuscitative (cpr) measures were instituted, and the patient regained consciousness after only two compressions. Following the events, the patient was transported (specifics not provided) to the emergency room (er) for evaluation and observation. No medical intervention was provided in the er. Per the physician, it was determined the patient became very anxious, and panicked when the blood leak occurred. The cm stated the patient is spanish speaking only and communication during the events was difficult. The patient was discharged in stable condition (date not provided) and resumed their normal hd therapy schedule. The dialyzer was not available to be returned for a manufacturer evaluation as it was reportedly discarded, and the lot number for the device was unknown.
