In this study, we examined the relationships among neuron-specific-enolase and hemolysis indicators such as free hemoglobin and lactate dehydrogenase after the introduction of veno-arterial extracorporeal oxygenation. Of the 91 patients who underwent veno-arterial extracorporeal membrane oxygenation in our hospital from January 1, 2018, to February 24, 2021, 68 patients survived for more than 24 h. Of these, 14 patients who were categorized into the better cerebral performance categories (1-3) and 19 patients who were categorized into the poor neurological prognosis category (4) were included. After the introduction of veno-arterial extracorporeal membrane oxygenation, neuron-specific-enolase was markedly higher in the poor neurological prognosis group than in the good neurological prognosis group (41.6 vs. 92.0, p = 0.04). A significant positive correlation was revealed between neuron-specific-enolase and free hemoglobin in the good neurological prognosis group (rs = 0.643, p = 0.0131). A similar relationship was observed for lactate dehydrogenase and neuron-specific-enolase in both the conscious (rs = 0.737, p = 0.00263) and non-conscious groups (rs = 0.544, p = 0.0176).

Hemolysis during VV-ECMO support arises from multiple factors associated with organ damage and poor outcomes. Therefore, close and prompt monitoring is needed. Hemolytic uremic syndrome (HUS) is characterized by hemolysis, acute renal failure, and thrombocytopenia. Hemolytic features of the disease may complicate VV-ECMO management. A 26-year-old man with a history of cerebral palsy underwent VV-ECMO for acute respiratory distress syndrome (ARDS) due to septic shock caused by bacterial translocation during treatment for HUS. He showed features of hemolysis, with elevated lactate dehydrogenase (LDH), fragmented red blood cells, and low haptoglobin levels. Plasma free hemoglobin was measured daily throughout the whole course of ECMO with levels higher than 10 mg/dL but not exceeding 50 mg/dL. The extracorporeal membrane oxygenation (ECMO) circuit pressures were carefully monitored to ensure the pump generated no excessive negative pressure. The patient was weaned off ECMO on the eleventh day. There have been several cases of VA-ECMO in patients with HUS; however, there is limited literature on VV-ECMO. As the days on VV-ECMO tend to be longer than those on VA-ECMO, features of hemolysis may complicate management. Although HUS did not directly influence the clinical course in the present case, features of hemolysis were continuously observed. This case highlighted the importance of standard ECMO monitoring, especially daily measurement of plasma free hemoglobin.","PeriodicalId":15177,"journal":{"name":"Journal of Artificial Organs","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141446231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While several reports have evaluated the performance of biological valves, echocardiography studies during exercise stress remain scarce. Furthermore, no current reports compare rate changes in the aortic valve area of biological valves under increased exercise load. Here, we performed exercise stress echocardiography in patients after AVR with Trifecta or Inspiris valves and compared the rates of change in aortic valve areas (AVA). In addition, hydrodynamic analysis at rest was conducted with four-dimensional flow magnetic resonance imaging (4D-flow MRI). Exercise stress echocardiography was performed in seven Trifecta and seven Inspiris patients who underwent AVR at our hospital while 4D flow MRI was performed in all but two Trifecta cases. Comparing the percentage change in AVA when loaded to 25 W versus at rest, Trifecta was greater than Inspiris (28.7 ± 36.0 vs - 0.8 ± 12.4%). The smaller AVA at rest was considered causative for this. Meanwhile, Trifecta systolic energy loss in the prosthetic valve segment on 4D-flow MRI (97.5 ± 35.9 vs 52.7 ± 25.3 mW) was higher than Inspiris. The opening of the Trifecta valve was considered to be restricted at rest and this may reflect the current reports of early valve degradation requiring reoperation. Taken together, we observed that the Trifecta design may promote faster wear due to higher valve stress.","PeriodicalId":15177,"journal":{"name":"Journal of Artificial Organs","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141446230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite initial treatment with inotropic drugs and intra-aortic balloon pump support, his hemodynamic status remained unstable. Transition to Impella CP mechanical circulatory support was made on day 6 owing to persistently low systolic blood pressure.

This review on total albumin losses considers albumin \"leaking\" into the dialysate and losses due to protein/membrane interactions (i.e. adsorption, \"secondary membrane formation\" and denaturation). The former are fairly easy to determine, usually varying at the level of ~ 2 g to ~ 7 g albumin loss per session. Such values, commonly accepted as representative of the total albumin losses, are often quoted as limits/standards of permissible albumin loss per session. On albumin mass lost due to adsorption/deposition, which is the result of complicated interactions and rather difficult to determine, scant in vivo data exist and there is great uncertainty and confusion regarding their magnitude; this is possibly responsible for neglecting their contribution to the total losses at present. Yet, many relevant in vitro studies suggest that losses of albumin due to protein/membrane interactions are likely comparable to (or even greater than) those due to leaking, particularly in the currently favoured high-convection HDF (haemodiafiltration) treatment. Therefore, it is emphasised that top research priority should be given to resolve these issues, primarily by developing appropriate/facile in vivo test-methods and related analytical techniques.","PeriodicalId":15177,"journal":{"name":"Journal of Artificial Organs","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11126488/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139491221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
