Event Description

The user facility reported to terumo cardiovascular that during cardiopulmonary bypass, there was plasma leakage at gas inlet and gas outlet side.Per user facility, the report documents the event and online data for a longer case with two sessions; first for approx.6.5h (including perfusion/reperfusion, etc) and second for approx.1.75h.In the second session, a plasma leakage was discovered and a second oxygenator was added after approx.0,25h perfusion time.The first session stopped @16:40 local time.The second session started @ 19:04 local time and stopped @ 20:47 local time; plasma leakage observed and 2nd oxy added.There is no act/heparin info documented since the last act value (@16:11).The plasma leakage was observed during the second session therefore it appears that the oxy was already in use (first session + standby) for approx.9h before the second session started.There was around 1 minute delay.There was less than 100ml blood loss + plasma leakage about 200ml.The product was changed out.The surgery was completed successfully.
