Event Description
|
The user facility reported to terumo cardiovascular that during cardiopulmonary bypass, low oxygenation occurred.As per user facility, during the circulatory arrest, (aortic dissection circulatory arrest, hypothermia at 25°c, total duration 263.33mn, aortic clamping 166.29, assistance only 94.53 cerebroplegia 92.24) no oxygenation or decarboxylation problems, the blood gases were correct, flow rate at 1.5l for 20-30 minutes, then in front of a slightly lowered nirs (near infrared spectroscopy), increase the flow rate to 1.7l until the end of the circulatory arrest.The surgeon then advised to resume the flow, signing the end of the circulatory arrest, so the fio2 was set at 100% on the sechrist, increased the sweep and requested act which was greater than 400.The flow was resumed for over a few minutes.It was observed on the cdi that the parameters are panicking: the pao² decreases despite the fio² to 100% and the pco² rises but remains "reasonable", then the anesthesiologists put 100% fio² on the ventilator.In a few seconds: we move on to galloping hypercapnia still the pao2 decreases inversely with pco2.The sweeping on the sechrist was increase to 10 or 12 l.Cardioplegia was done, then the blood in all the tubing is black, pao² goes down to about 50mmhg on the cdi, pco² is 110mmhg.The parameters on the sechrist was kept at maximum fio² 100% and scan 12.Cec was changed with no problem on it.However, while they debubbled the 2nd cec it still has no improvements on the gases on the cdi.Results correlated by the blood gases that were done very closely as soon as they started to no longer properly oxygenate the patient.The product was changed out.It is unknown if there was a blood loss.It is unknown if there was a delay and if the procedure was completed successfully.

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 exp 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, 3331, 213, 67).Method code #1: 10 - testing of actual/suspected device.Method code #2: 3331 - analysis of production records.Results code: 213 - no device problem found.Conclusions code: 67 - no problem detected.The actual sample was received and was visually inspected upon receipt with no obvious anomalies such as break in the appearance.After having been rinsed and dried, the actual sample was tested for its gas transfer performance in accordance with the factory's shipping inspection protocol.No anomalies were revealed in the gas transfer performance of the actual sample, with the obtained values meeting the factory specifications.The investigation result verified that the actual sample, after having been rinsed, was the normal product with no issue in the gas transfer performance.From the available information, the possibilities can be inferred; however, it is difficult to determine the definitive root cause.All available information has been placed on file in quality management for appropriate tracking, trending, and follow-up.
