This study investigates the impact of oxygen delivery (DO2) during cardiopulmonary bypass (CPB) on major clinical outcomes in cardiac surgery patients. Maintaining adequate DO2 during
This prospective, randomized, and blinded study compared the impacts of traditional Plasma-Lyte A-based del Nido cardioplegia (PL DN) and a modified Ringer’s lactate-based formulation (LR DN) on clinical outcomes in patients undergoing coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB). Results showed that while both formulations had similar effects on several clinical parameters, PL DN offered superior myocardial protection, as indicated by lower postoperative cardiac enzyme levels and reduced need for epinephrine.
This case study details a novel approach to avoid cardioplegia delivery complications during a high-risk redo mitral valve replacement. The 75-year-old patient, with severe mitral regurgitation and mild aortic regurgitation, underwent minimally invasive surgery using systemic hyperkalemia and circulatory arrest. The method eliminated the need for aortic cross-clamping, achieving effective myocardial protection and an uneventful recovery, despite complex surgical challenges.
This study addresses the critical issue of oxygenator failure during cardiopulmonary bypass (CPB), a rare but high-risk event. It explores protocols and techniques for addressing oxygenator malfunction, including traditional oxygenator change-outs and alternative approaches like arterial and venous piggyback methods. The authors emphasize the need for institutional preparation, including written protocols and routine emergency drills, and propose a venous piggyback technique as a safer first-line response to improve patient outcomes.
The article introduces a Professional Advancement Model (PAM) tailored for perfusionists to address high turnover and enhance retention. Drawing from PAM frameworks in other healthcare professions like nursing and advanced practice providers, the author proposes a four-tier system: Perfusionist I through IV. Progression is determined by points earned in categories such as leadership, clinical excellence, education, and service, alongside experience requirements. The PAM offers structured career growth, salary increments, and institutional benefits, serving as a retention strategy and professional growth tool for perfusionists.
This article discusses the significance of monitoring indexed oxygen delivery (DO2i), oxygen extraction ratio (O2ERi), and carbon dioxide production (VCO2) during normothermic regional perfusion (NRP) in Donation after Circulatory Death (DCD) donors. These metrics ensure optimal oxygenation, reduce ischemic injuries, and prevent organ dysfunction. Personalized perfusion strategies, informed by these parameters, improve organ viability and transplantation outcomes while lowering post-transplant complications like acute kidney injury.
This study investigates the relationship between cerebral overperfusion and postoperative delirium (POD) in cardiac surgery patients. Despite reduced cortical metabolism, patients with POD exhibited increased cerebral blood flow, measured via transcranial Doppler. Low bispectral index (BIS) values indicated reduced metabolism, but no differences in autoregulation impairments were noted. The findings suggest a mismatch between cerebral blood flow and metabolism contributes to POD, independent of cerebral autoregulation.
This case report details the anesthetic management of a 77-year-old female with hypertrophic obstructive cardiomyopathy (HOCM), undergoing surgery for ileal adenocarcinoma. It highlights challenges such as preventing left ventricular outflow tract obstruction and maintaining hemodynamic stability. A tailored approach, including vigilant monitoring, goal-directed fluid therapy, and careful use of vasopressors, ensured successful outcomes. The report underscores the importance of meticulous perioperative planning in HOCM cases.
The GDT trial compares goal-directed tranexamic acid (TXA) administration guided by rotational thromboelastometry (ROTEM) to preemptive TXA administration in cardiovascular surgery. This multi-center, double-blind, randomized trial aims to determine non-inferiority in reducing postoperative bleeding. Secondary outcomes include transfusion rates, thromboembolic complications, seizures, and hospital costs. The study hypothesizes that selective TXA administration will lower adverse events compared to preemptive dosing.
This study examined the impact of serum sodium trajectory on 30-day mortality in septic patients after cardiopulmonary bypass (CPB) surgery using the MIMIC-IV database. Among 1,038 patients, serum sodium trajectories were classified into three groups, with higher levels linked to increased mortality. Elevated fluctuations, even within normal sodium ranges, were associated with adverse outcomes. These findings highlight the need for close monitoring and sodium management in critically ill patients undergoing CPB.
