Hemolysis is a potential complication and is associated with significantly increased morbidity and mortality. The etiology of hemolysis in neonates is multifactorial, including shear forces generated by the ECMO pump, higher flow resistance from smaller tubing and smaller cannulas, the oxygenator, and other patient factors. Centrifugal pumps and oxygenators commonly have shunts with partially occluding clamps to regulate blood flow. We hypothesized that these clamps are significant contributors to hemolysis.MethodAn in vitro study was conducted with three identical ECMO circuits containing an integrated polymethylpentene (PMP) oxygenator and centrifugal pump (Cardiohelp HLS 5.0) and 1/4″ arteriovenous (AV) loop tubing. The circuits were primed with equal components, including expired ABO-compatible packed red blood cells (pRBCs), 25% albumin, 5% albumin, sodium bicarbonate, heparin, and calcium chloride. Circuit A had a completely occluded shunt. Circuit B had a partially occluded shunt, allowing 500 mL/min of shunt flow back to the oxygenator. Circuit C had a fully open shunt, generating 1000 mL/min of shunt flow back to the oxygenator. Plasma-free hemoglobin values were measured serially over 5 days.ResultsBaseline plasma-free hemoglobin levels were equal in all three circuits.

Two standard cardioplegic solutions viz. Del Nido solution (DNS) and St Thomas solution (STS) are widely used in cardiac surgeries. The DNS is a single-dose CP that offers superior myocardial protection in adults, and studies have claimed myocardial injury in STS patients. The elevated circulatory level of citric acid cycle intermediate, succinate is a metabolic hallmark of ischemia. Its rapid oxidation after reperfusion causes ischemia-reperfusion (IR) injury through mitochondrial reactive oxygen species production. Succinate has been identified as an early marker of IR injury through blood plasma/serum-based clinical metabolomics studies. The primary objective of the study was metabolomic profiling of succinate from the coronary sinus and venous blood.MethodsTwo blood samples each were obtained from coronary sinus (CS) & venous reservoir from patients before the application of aortic cross-clamp and after the release of aortic cross-clamp from 22 patients divided into two groups. The blood-serum metabolic profiles were measured by 800 MHz NMR spectrometer and compared using univariate statistical analysis methods. The study also compared the two groups' cardiopulmonary bypass variables and left ventricle functions.ResultDNS leads to increased serum levels of succinate in the coronary sinus blood after the reperfusion compared to STS. The results of our study are consistent with a previous study that found DNS administration (90 minutes) increases the inflammatory response in the myocardium.ConclusionNMR-based serum metabolomics revealed significantly increased circulatory succinate in coronary sinus blood of patients administered with DNS cardioplegia in comparison to STS cardioplegia.

However, it can create an environment for students to be passive learners in the classroom. Alternatively, active learning is a pedagogical approach intended to encourage students to engage with content in manners which have been associated with improved exam performance, final course grades, clinical reasoning skills, and critical thinking skills. Given that perfusion is inherently a profession where didactic information must be applied in practice, the implementation of active learning in didactic courses is worth considering. Although active learning is practiced in perfusion education through participation in simulations and clinical rotations, there are no easily identifiable active learning resources available to supplement didactic perfusion courses. In response, written active learning activities were specifically designed for didactic perfusion courses.MethodsThe activities were designed based on the format for guided inquiry worksheets, the incorporation of the learning cycle, and the implementation of process oriented guided inquiry learning (POGIL) strategies. Key concepts were identified, learning objectives were specified, and models (figures or tables of data) were created as targets of engagement and analysis. Following each model, questions and prompts are given to guide students through identifying, understanding, and exploring the concepts incorporated in the activity as well as opportunities to apply the newly gained knowledge and understanding.ResultsTen active learning activities have been developed based on the methods summarized above.ConclusionWhile the purposes of this paper are to inform the perfusion community of active learning and to share guidelines on how to create active learning activities for didactic perfusion courses, the goals of the activities are to provide examples to perfusion educators and to guide students in understanding basic perfusion concepts in a clinically relevant manner. It is recommended that perfusion students complete these activities alongside their didactic perfusion courses.</p>","PeriodicalId":49707,"journal":{"name":"Perfusion-Uk","volume":" ","pages":"1559-1566"},"PeriodicalIF":1.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143034731","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}
