Pharmacologic and Technologic Progress in Cardiac Anesthesia: Evidence from Recent Clinical Trials

Background: Recent advancements in cardiac anesthesia have significantly reshaped the specialty, ensuring hemodynamic stability, organ protection, and pain control during complex cardiac surgeries. Objective: The aim of this study is to systematically review and synthesize recent clinical trial evidence on advancements in cardiac anesthesia with a focus on intraoperative monitoring technologies, pharmacologic innovations, organ protection strategies and patient-centered outcomes to inform and guide future anesthetic practices in cardiac surgery. Methods: A systematic literature search was conducted on PubMed and Google Scholar to identify clinical trials and randomized controlled trials related to cardiac anesthesia published between January 2020 and June 2025. After identifying 33,888 articles and assessing eligibility using scale for the assessment of narrative review articles (SANRA) scoring, 9 studies were included, following preferred reporting items for systematic reviews and meta-analyses (PRISMA) 2020 guidelines for methodological transparency. Results: 9 randomized studies found that pupillometry-guided analgesia reduced opioid use by 47.2% and improved intraoperative hemodynamic stability. Remifentanil showed dose-dependent nociceptive suppression, but higher doses increased vasopressor requirements. Benzodiazepine-free protocols reduced postoperative delirium risk. Dexmedetomidine provided stable sedation during electrophysiology procedures. N-acetylcysteine provided hepatic protection and reduced intensive care unit (ICU) stay in valve surgery. Sevoflurane preserved renal function better than total intravenous anesthesia (TIVA) in pediatric patients. wide-awake local anesthesia no tourniquet (WALANT) technique reduced bleeding complications during cardiac device implantation. Conclusion: Innovations in cardiac anesthesia have improved patient care through individualized, multimodal, and technology-supported approaches. Future developments should standardize monitoring protocols, refine anesthetic agents, and integrate advanced training techniques.
