Event Description
|
The user facility reported to terumo cardiovascular that during cardiopulmonary bypass, the co2 was unable to be blown off.The patient was being cooled to 18 degrees celsius.The oxygenation was fine, however, the co2 continued to increase.The oxygenator was changed out during the planned circulatory arrest.*minor blood loss due to the patient being hemodiluted per the circulatory arrest case *product was changed out *procedure completed sucessfully.

This follow-up report is submitted to fda in accord with applicable regulations.Upon further investigation of the reported event, the following information is new and/or changed: d4 (additional device information - added expiration date); g4 (date received by manufacturer); g7 (indication that this is a follow-up report); h2 (follow-up due to additional information and device evaluation); h3 (device evaluated by manufacturer); h4 (device manufacture date); h6 (identification of evaluation codes 10, 11, 3331, 213, 67).Method code #1: 10 - testing of actual/suspected device.Method code #2: 11 - testing of device from same lot/batch retained by manufacturer.Method code #3: 3331 - analysis of production records.Results code: 213 - no device problem found.Conclusions code: 67 - no problem detected.The actual sample was visually inspected and found no breakage or other obvious anomaly that could lead to the poor gas transfer performance.After having been rinsed and dried, it was measured for its o2 transfer and co2 removal performance in accordance with the factory's shipping inspection protocol.No anomalies were revealed in the gas transfer performance of the actual sample.The investigation result verified that the actual sample was the normal product with no issue in the gas transfer performance.A review of device history record and incoming inspection record of the involved product/lot number combination confirmed that there were not any indications of anomaly in them.All available information has been placed on file in quality management for appropriate tracking, trending, and follow-up.

Event Description
|
Additional information has been received from the user facility.The patient had aortic insufficiency, a bicuspid aortic valve, and aortic root dilatation.The patient was immediately cooled to 18 degrees celsius in preparation for circulatory arrest.The pco2 began to rise so the sweep was adjusted to accommodate; however, it kept rising.The co2 was flowing at approximately 1.5 lpm.Flows were decreased and the recirculation line was opened, this only helped somewhat.All gas lines were checked, adequate gas flow was going to the oxygenator.Occasionally, the po2 would rise into the upper 70s.Since the patient was cold for quite some time, it was decided to change out the oxygenator.There was a delay of 4 minutes as the new oxygenator was primed, de-aired and began the retograde cerebral perfusion.Once the oxygenator was changed, pco2 was difficult to manage until the patient reached approximately 34 degrees celsius.The pco2 was in the 60s and 70s a various times.The numbers were verified with blood samples.
