Apheresis therapies separate plasma components from blood using membrane screening or centrifugation methods. TPE aims to remove substances involved in the pathophysiology of diseases. It selectively removes high-molecular-weight molecules, substances with prolonged half-life, and those associated with disease pathogenesis. TPE can be performed using membranes or centrifugation, with replacement of extracted plasma volume using albumin or fresh frozen plasma. TPE requires specific competencies in nephrology and can be prescribed and monitored by nephrologists and performed by dialysis nursing staff. TPE can be combined with adsorption-based therapies to enhance its effect, and this approach is called plasma filtration adsorption. Another variation is double plasma filtration, which selectively removes substances based on molecular size. TPE can also be combined with lipoprotein removal strategies for managing familial hypercholesterolemia.

Several CRRT-related factors may have influenced the delivered CL of midazolam and its metabolites.

Midazolam, 1-OH-midazolam, and 1-OH-midazolam-glucuronide concentrations were 2,849 (0-6,700) μg/L, 153 (0-295) μg/L, and 27,297 (1,727-39,000) μg/L, respectively. The SD was 0.03 (0.02-0.03) for midazolam, 0.05 (0.05-0.06) for 1-OH-midazolam, and 0.33 (0.23-0.43) for 1-OH-midazolam-glucuronide. The delivered CRRT CL was 1.4 (0-1.7) mL/min for midazolam, 2.7 (0-3.5) mL/min for 1-OH-midazolam, and 15.7 (4.0-27.7) mL/min for 1-OH-midazolam-glucuronide.</p><p><strong>Conclusions: </strong>Midazolam and 1-OH-midazolam were not removed during CVVHD and CVVHDF. However, 1-OH-midazolam-glucuronide was removed reasonably, approximately up to 43%. CRRT modality, filter integrity, and downtime affect this removal. These data imply a personalized titration of midazolam in critically ill patients with renal failure and awareness for the additional sedative effects of its active metabolites.</p>","PeriodicalId":8953,"journal":{"name":"Blood Purification","volume":" ","pages":"107-113"},"PeriodicalIF":3.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10836747/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71477639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
