Manufacturer Narrative

The event occurred in canada.It was reported that while supporting a patient on veno-veno ecls support with hls set advanced 5.0.A circuit change out was required due to failing blood gases (bad oxygenation).The circuit was successful changed out.The affected hls set was discarded due to covid 19.The patient was infected with covid-19.As stated by the getinge medical affairs team and in reference to the literature [1] covid-19 diseases can be associated with intravascular coagulation activation, microcirculation disorders and increased risk of thromboembolism despite good systemic anticoagulation.The increased risk of thrombosis and coagulopathy in ecmo patients is a result of a combination of processes driven by the disease occurring in synergy with the effect of the extracorporeal circuit on the coagulation system.[1] yusuff h, zochios v, brodie d."thrombosis and coagulopathy in covid-19 patients requiring extracorporeal membrane oxygenation" asaio j.2020;66(8):844-846.Doi:10.1097/mat.0000000000001208 with reference to the risk assessment hls set advanced 5.0 / hls set advanced 7.0, dms#1468452, v26 and in consultation with the manager medical affairs the following events can contribute to clotting in the circuit: air remains in or enters the circuit.Hemostasis.Air or blood remains in luer lock access port.Too low anticoagulation.Too low at level, effect of heparin is too limited.Protamine sulfate enters the hls set.Administration of substitution of congealable substance such as plateles.(consumption) coagulopathy.Thrombozytopenia.The most probable root cause for the increased pressure drop are clots in the oxygenator leading to a blockage and thus an extension of the diffusion path lowering the oxygenating performance.The production history records (dhr) of the affected hls module were reviewed on 2021-07-19.Following tests are performed according to the bop as a 100 % inspection: pressure test heat exchanger; leak test water/gas side ; pressure test blood side; final functional test.According to the final test results, all hls modules passed the tests as per specifications.Production related influences are unlikely.Based on the investigation results the reported failure "bad oxygenation" could be confirmed, but not product related malfunction.The occurrence rate was calculated for the reported issue and it was determined that this is not a systemic issue.Therefore, no remedial action is required.The occurrence rate related to the reported issue is currently being monitored as part of maquet cardiopulmonary¿s trending program and additional investigations or corrections will be implemented in case of adverse trending.
