Systemic anticoagulation with heparin during CPB should be completely neutralized by administering protamine to restore normal hemostasis. Activated clotting time (ACT) is a major marker of anticoagulation management during CPB. However, studies have shown that ACT measurements can vary predictably with different point-of-care testing ACT devices, suggesting the importance of considering the ACT device when determining the target ACT. Otherwise, the amount of heparin used and circulating during CPB can be unnecessarily high. Calculating an optimal protamine dose (PD) is challenging. Yet, newer strategies and heparin concentration-based dosing indicate that average doses of 60-90 mg/m<sup>2</sup> are generally sufficient. This equates to a protamine-to-heparin ratio of approximately 0.5-0.8:1 of the first heparin bolus to establish the target ACT before going on CPB or a 0.3-0.5:1 of the total heparin dose during CPB. PD exceeding 90 mg/m<sup>2</sup> may result in residual free protamine. Excessive use of heparin and protamine has been associated with increased post-operative bleeding. This review discusses several considerations in planning an anticoagulation strategy during CPB, focusing on the predictable differences of ACT devices and strategies to determine the optimal PD. The aim is to administer a safe and minimal amount of heparin to protect the CPB circuit and patient from thrombosis and CCA, and to administer the optimal amount of protamine to completely neutralize the circulating heparin without leaving residual free protamine.</p>","PeriodicalId":519952,"journal":{"name":"The journal of extra-corporeal technology","volume":"58 2","pages":"164-171"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13281330/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148280703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, few sites have formalized patient selection criteria, and even fewer have a robust multidisciplinary ECMO team to determine patient candidacy. Analyzing current literature revealed weaknesses in existing research on VA ECMO patient selection criteria. Significant issues include the use of small sample sizes, lack of randomized controlled trials, lack of personalization of ECMO initiation decisions, study heterogeneity, and inclusion of patients who received ECMO without including patients who were considered for but not given ECMO. Among the available studies, the Survival After Venoarterial ECMO (SAVE) score has shown the greatest promise in selecting VA ECMO patients, excluding those undergoing extracorporeal cardiopulmonary resuscitation (ECPR) and postcardiotomy (PC) ECMO. The SAVE score has demonstrated good discrimination in non-ECPR and non-PC ECMO groups. Further research is needed on the predictive value of SAVE score risk classes and the discrimination of the SAVE score excluding PC ECMO and ECPR groups. The modified SAVE score, which also includes lactate assessment, has shown the greatest promise for selecting ECPR and PC ECMO patients for VA ECMO. The modified SAVE score requires more external validation. Site-level research indicates that consultation with a multidisciplinary ECMO team, which collectively makes decisions about ECMO candidacy, has resulted in significantly improved patient survival outcomes compared with a one- or two-physician decision-making mechanism for VA ECMO initiation. The ECMO team approach is a rich area for future research, and sites should publish their patient outcomes before and after implementation.</p>","PeriodicalId":519952,"journal":{"name":"The journal of extra-corporeal technology","volume":"58 2","pages":"146-163"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13281281/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148280753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
