However, its long context-sensitive half-life is of concern. Remimazolam may be a suitable alternative. This study compares the sequestration of remimazolam and midazolam in an in-vitro ECMO circuit. Sixteen in-vitro ECMO circuits were prepared with either Ringer lactate or a combination of red blood cells and fresh frozen plasma. Each circuit operated at a flow of 3 L/min at 37°C for 24 hours. Remimazolam (1 mg) or midazolam (1 mg) was injected, creating four experimental groups. Blood samples for measurement of drug concentrations were collected at predefined time points. The percentage of drug remaining at 24 hours was comparable for remimazolam and midazolam (mean [standard deviation {SD}]: 3.7% [0.9] and 2.9% [0.5]) in Ringer lactate-perfused circuits and higher for midazolam compared with remimazolam (mean [SD] 52% [13] and 15% [2]) in blood-perfused circuits. The concentration of the remimazolam metabolite CNS7054 increased from 29 (8) ng/ml at 5 minutes to 173 (31) ng/ml at 24 hours. Drug sequestration of remimazolam in in-vitro ECMO circuit is comparable to midazolam in circuits perfused with Ringer lactate. In circuits perfused with blood, the percentage of drug remaining at 24 hours is lower for remimazolam.","PeriodicalId":8844,"journal":{"name":"ASAIO Journal","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144483022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One axial pump (HeartMate II) and two centrifugal pumps (HeartMate 3 and BrioVAD) were chosen for this study. In vitro experiments with healthy human blood and computational fluid dynamics simulations were performed to compare high-mechanical shear-induced blood trauma in these devices. Regions of higher shear stresses were identified. Power-law relations between shear stress and blood damage were implemented to assess hemolysis, platelet activation, and platelet receptor shedding of key functional receptors (glycoprotein [GP] Ibα, and GPVI) caused by these devices. HeartMate II caused the most severe blood trauma among these three devices, producing an order of magnitude larger values for hemolysis and platelet activation compared with HeartMate 3 and BrioVAD. Also, HeartMate II consistently exhibited the highest levels of receptor shedding, approximately double those caused by the HeartMate 3 and BrioVAD. The HeartMate 3 and BrioVAD centrifugal pumps showed similar performance in terms of blood damage.","PeriodicalId":8844,"journal":{"name":"ASAIO Journal","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144473879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study objective was to evaluate the safety and efficacy of a nitric oxide-generating extracorporeal carbon dioxide removal (ECCO2R) system without systemic anticoagulation in a translational swine model. We hypothesized that nitric oxide reduces circuit thrombosis, without untoward systemic effects. Anesthetized, mechanically ventilated swine (50-60 kg) received bicaval jugular cannulation for 72 hour venovenous ECCO2R. Control (n = 6) received a standard ECCO2R device with systemic heparinization. Treatment (n = 6) received the same device, but with nitric oxide-generating circuitry and 80 ppm nitric oxide added to sweep gas, without systemic heparinization. No between-group differences in vitals, ventilator settings, blood gases, extracorporeal gas exchange, or fluid balance occurred. In both groups, ECCO2R enabled reduction in tidal volume. Oxygenator thrombus area, quantified following dissection and imaging, was reduced in treatment (10.2 ± 1.2%) versus control (15.2 ± 1.6%) (p = 0.03). One control oxygenator occluded. No nitric oxide-related adverse effects were observed, including methemoglobinemia. Nitric oxide-enhanced ECCO2R enabled 72 hours of support without systemic anticoagulation, and without altering oxygenator performance or causing untoward systemic effects. Future studies are needed to investigate efficacy in subjects with underlying coagulopathy and/or contraindications for systemic anticoagulation.","PeriodicalId":8844,"journal":{"name":"ASAIO Journal","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144324398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is unknown to what degree the use of HFOV provides a measurable benefit to infants with congenital diaphragmatic hernia (CDH) receiving extracorporeal life support (ECLS). We sought to determine whether pre-ECLS use of HFOV compared to conventional mechanical ventilation (CMV) was associated with differences in mortality. Neonates who underwent ECLS for CDH were identified within the Extracorporeal Life Support Organization (ELSO) Registry. Patients were categorized as those on HFOV versus on CMV immediately before initiating ECLS. Patients were matched 1:1 for severity based on pre-ECLS covariates using the propensity score (PS) for ventilator choice. There were 2,892 infants with an overall mortality of 47.3%. Conventional ventilation was used before ECLS in 677 (23.4%) and HFOV in 2,215 (76.6%). Of these, 1,354 infants were matched (1:1) based on ventilator choice (677 CMV and 677 HFOV). High-frequency oscillatory ventilation was associated with 49% higher odds of mortality based on 677 PS matched pairs (odds ratio [OR] = 1.492, 95% confidence interval [CI]: 1.200-1.856, p < 0.001).

Fifty-two year old male who suffered polytraumatic injuries and developed acute respiratory syndrome was placed on veno-venous (VV) ECMO to treat severe respiratory failure. On ECMO day 1, the patient was undergoing treatment for urinary tract infection due to susceptible Pseudomonas aeruginosa (PsA). On ECMO day 22, the patient developed fulminant septic shock and tracheal aspirate and blood cultures both grew MDR PsA and Enterobacter cloacae complex (ECC) and ultimately died on day 23. There were significant microbiome and antimicrobial resistance changes that preceded sepsis on day 22, as evidenced by the increase in oral PsA colonization and expansion of resistance genes, such as KPC and OXA-50, which suggest several possible reservoirs for infection outside of the circuit.

A retrospective review of patients who underwent lymphatic ligation following VA-ECMO from 2022 to 2024 was performed. Fluorescent imaging and intradermal indocyanine green injection were used to identify and ligate lymphatic leaks within the debrided wound bed. Ten patients with a mean age of 48.3 years were included. The mean number of lymphatics ligated was 5. Mean days from decannulation to ligation and from ligation to drain removal were 18.4 and 22.2, respectively. There was a significant decrease in drain output immediately following ligation (197.4 ml/day vs. 64.2 ml/day; p = 0.016). A shorter time from decannulation to ligation was significantly correlated with a decrease in drain output. A higher drain fluid lymphocyte percentage was significantly correlated with a shorter time to drain removal. Fluorescent imaging-guided lymphatic ligation is an effective method for treating lymphatic leak after decannulation from VA-ECMO. Drain fluid analysis and early consultation with plastic surgery should be encouraged in the event of high-output lymphocele.","PeriodicalId":8844,"journal":{"name":"ASAIO Journal","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144274076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
