Efficacy of Adjunct Hemoperfusion Compared to Standard Medical Therapy on 28-Day Mortality in Leptospirosis Patients with Renal Failure and Shock: A Single-Center Randomized Controlled Trial

This study evaluates the impact of hemoperfusion (HP) on 28-day mortality in leptospirosis patients with renal failure and septic shock. A total of 37 patients were randomized to receive either standard medical therapy (SMT) or SMT with HP. The HP group showed a 36.84% risk reduction in 28-day mortality and significant improvements in inflammatory markers, renal function, and pulmonary function. Hemoperfusion was shown to be a safe and effective adjunct therapy, promoting faster recovery and increased survival rates.

Brain Death Donors on Extracorporeal Membrane Oxygenation Support

This study examines 15 brain death donors on extracorporeal membrane oxygenation (ECMO) support, admitted to a specialized intensive care unit between 2018 and 2023. The study evaluates the effect of a strict hemodynamic monitoring schedule during a 6-hour observation period on the utilization rate of organs. Results show an increase in utilization rates from 78% to 88% with no significant differences in donor characteristics or hemodynamic data between periods. Most donors required multiple vasoactive drugs to maintain adequate perfusion.

Intraoperative Haemoadsorption for Antithrombotic Drug Removal During Cardiac Surgery: Initial Report of the International Safe and Timely Antithrombotic Removal (STAR) Registry

This study investigates the monocyte-to-lymphocyte multiplying platelets ratio (MLPR) as a novel inflammatory marker for predicting acute kidney injury (AKI) after cardiac surgery with cardiopulmonary bypass (CPB). Through analysis of 2387 patients, the study found that both MLPR and monocyte-to-lymphocyte ratio (MLR) were significant risk factors for AKI. MLPR displayed a J-shaped curve in relation to AKI, indicating its potential as a useful clinical tool for early AKI detection in cardiac surgery patients.

Standard Versus High Cardiopulmonary Bypass Flow Rate: A Randomized Controlled Subtrial Comparing Brain Injury Biomarker Release

This study aimed to compare the release of brain injury biomarkers between standard and high cardiopulmonary bypass (CPB) flow rates during elective cardiac surgery. Conducted at Sahlgrenska University Hospital in Sweden, forty patients were randomly assigned to either a standard (2.4 L/min/m²) or high (2.9 L/min/m²) CPB flow rate. The results indicated no significant differences in biomarker levels or the occurrence of postoperative delirium between the two groups. Age and sex were among factors associated with biomarker levels.

Global Perfusion Practice Survey: Readiness of On-Call and Emergency Operation Rooms

This survey examines the readiness of on-call and emergency operation rooms for perfusion-related procedures during urgent situations in cardiac surgery. Data from 236 healthcare professionals highlight varied preferences for circuit readiness, influenced by caseload, response times, and other factors. The study underscores the need for standardized protocols to enhance perfusion safety and improve patient care.

Haemoadsorption

Impact of Extracorporeal Haemoadsorption During Prolonged Cardiopulmonary Bypass on the Incidence of Acute Kidney Injury

This study investigates the effects of haemoadsorption (HA) therapy on inflammatory markers and renal damage indices during cardiopulmonary bypass (CPB) and the early postoperative period. Conducted at a single tertiary care center, the retrospective analysis compared three groups of patients who underwent CPB for over 120 minutes. The results showed that haemoadsorption therapy did not significantly reduce the incidence of acute kidney injury (AKI) but decreased the need for renal replacement therapy.

Perfusion Measures and Outcomes (PERForm) Registry: First Annual Report

The first annual report of the Perfusion Measures and Outcomes (PERForm) registry details patient characteristics and cardiopulmonary bypass (CPB) practices from 2019 to 2022 across 42 hospitals. Covering data from 40,777 adult patients, the report highlights trends in myocardial protection, glucose, anticoagulation, temperature, anemia, and fluid management. Key findings include the stability of hematocrit levels and increased pump sucker termination before protamine administration, indicating improved compliance with evidence-based guidelines but identifying areas for enhanced patient safety.

Perfusion Learning

Adapting and Applying Student-Centered Learning in a Perfusion Clinical Rotation

This study outlines the transformation of perfusion clinical education from a teacher-centered to a student-centered model. By incorporating reflective practice, self-evaluation, and problem-based learning, the Mayo Clinic’s Perfusion Work Group aims to enhance the clinical training of student perfusionists. Changes include reversing student preceptor evaluations, biweekly student-led educational sessions, and establishing clear skill levels. These methods foster reflective practice, self-assessment, and evidence-based learning, ultimately promoting lifelong reflective perfusionists.

Venovenous Bypass in Liver Transplantation: Exploring the Benefits, Efficacy, and Safety

This article explores the utilization of venovenous bypass (VVB) in liver transplantation (LT), highlighting its benefits, efficacy, and safety. Although VVB helps maintain hemodynamic stability and improve patient outcomes, its global use has declined due to concerns about heparinization, major bleeding, and the need for specialized expertise. Recent advancements in percutaneous cannulation techniques and extracorporeal technology have enhanced the safety of VVB. Studies show that VVB reduces the incidence of acute kidney injury, operative time, and blood loss without increasing morbidity or mortality. Despite these benefits, alternative techniques are being increasingly adopted. The article emphasizes the role of VVB in complex clinical scenarios and calls for continued research to optimize its application in liver transplantation.

A Randomized Trial of Intravenous Amino Acids for Kidney Protection

This study investigated the efficacy of intravenous amino acids in reducing acute kidney injury (AKI) in patients undergoing cardiac surgery. A total of 3511 patients were randomized to receive either amino acids or a placebo. Results showed a significant reduction in AKI occurrence in the amino acid group (26.9%) compared to the placebo group (31.7%), with a relative risk of 0.85. The severity of AKI and the need for kidney-replacement therapy were also lower in the amino acid group. No major differences in other secondary outcomes or adverse events were observed.
