The user facility reported to terumo cardiovascular that during cardiopulmonary bypass, there was a plasma leakage.The operation was an aorta dissection, which was an acute situation.The total cpb time was 434 minutes, at approximately 330 minutes the leakage appeared.Initially, a co2-removal problem appeared during the rewarding phase of the surgical procedure, indicating increased gas flow rates at gas line pressures above 25 mmhg.Subsequently, plasma leakage was noted at the gas outlet port.There was delay during the procedure; for the nx19 needed to be replaced due to oxygenator failure.The exchange was performed during a quick circulatory discontinuation of 45 seconds.Impact on the surgical procedure as such is therefore not assessable.The surgery was not completed, the patient expired on the operating table.The product was changed out.There was a blood loss of approximately 185 ml.
