Global Teamwork in Modern Myocardial Protection: Alternative Base Solutions for del Nido Cardioplegia

Alternative Base Solutions for del Nido Cardioplegia: Composition, Rationale, and Clinical Evidence

This comprehensive review examines alternative crystalloid and whole-blood base solutions for del Nido cardioplegia, including normal saline, lactated Ringer’s, plain Ringer’s, Isolyte S, Ionosteril, and whole blood. Drawing on experimental models, randomized trials, and clinical studies, the article demonstrates that these alternatives provide myocardial protection and postoperative outcomes comparable to Plasma-Lyte A when appropriately buffered, supporting cost-effective and globally accessible cardiac surgery practice.

Active Myocardial Protection During Cardioplegic Arrest

Molecular and Cellular Mechanisms of Cardioplegic Protection in Surgical Myocardial Revascularization

This comprehensive review explores how cardioplegia actively protects the myocardium during coronary artery bypass grafting. Beyond inducing cardiac arrest, cardioplegic solutions modulate calcium homeostasis, mitochondrial function, oxidative stress, inflammation, and apoptosis. By suppressing electromechanical activity and metabolic demand, cardioplegia prolongs ischemic tolerance and mitigates reperfusion injury, offering critical insights for optimizing myocardial protection strategies in modern cardiac surgery.

Comparison of 6% Hydroxyethyl Starch 130/0.4 vs 5% Albumin

Comparison of 6% Hydroxyethyl Starch 130/0.4 vs 5% Albumin in Cardiopulmonary Bypass for Cardiac Surgery

This meta-analysis evaluated 12 randomized trials (908 patients) comparing 6% hydroxyethyl starch (HES) 130/0.4 with 5% albumin during cardiopulmonary bypass in cardiac surgery. Most outcomes—including blood loss, transfusion rates, ICU stay, hospital stay, and mortality—were similar between groups. However, HES use was associated with a significantly higher risk of acute kidney injury, highlighting renal safety concerns despite comparable hemodynamic efficacy.

Determination of Insensible Water Loss and Sodium Accumulation Behavior from the Medtronic Nautilus ECMO Oxygenator: An In Vitro Study

Determination of Insensible Water Loss and Sodium Accumulation Behavior from the Medtronic Nautilus ECMO Oxygenator: An In Vitro Study

This in vitro study examined insensible water loss and sodium accumulation in the Medtronic Nautilus ECMO oxygenator. Using varying sweep gas rates over 24 hours, researchers found a strong linear relationship between sweep gas flow and fluid loss. The rate was approximately 72.5 mL/day per 1 L/min sweep gas. Sodium accumulation was observed but not statistically confirmed due to sample size. These findings are critical for managing fluid balance and hypernatremia risk in ECMO patients.

Tranexamic Acid Does Not Have a Dose-Dependent Effect on Postoperative Delirium After Cardiac Surgery — A Retrospective Cohort Study

This retrospective study examined over 5,500 patients undergoing cardiac surgery to assess whether higher doses of tranexamic acid (TXA) reduce postoperative delirium (PD). Despite TXA’s known anti-inflammatory effects and role in stabilizing the blood-brain barrier, the study found no significant dose-dependent reduction in PD. CAM-ICU assessments showed similar PD rates across all dosing groups, highlighting PD’s multifactorial nature and the need for further prospective trials.

An In-Vitro Study of the Timing Between Protamine Sulfate Administration and Cardiotomy Suction Termination

This in-vitro study evaluates the optimal timing for discontinuing cardiotomy suction during cardiopulmonary bypass (CPB) when reversing heparin anticoagulation with protamine sulfate. Using porcine blood samples, the researchers assessed activated clotting times (ACTs) after administering a protamine test dose (PTD) and 1/3 of the full dose. Results showed significant ACT reductions after each stage, suggesting early suction termination is vital to preserve circuit integrity.
