Re-Dosing del Nido cardioplegia in adult cardiac surgery: Perfusion characteristics and outcomes--Is there an optimal redosing strategy?

Objectives: del Nido cardioplegia is utilized for myocardial protection in adult patients undergoing cardiac surgery; however, no standardized re-dosing protocol exists. We describe perfusion characteristics and clinical outcomes in adult cardiac surgery patients who were re-dosed with del Nido cardioplegia.

Methods: Chart review was performed for adult patients undergoing cardiac surgery (specific inclusion/exclusion criteria below) who received exactly two doses of del Nido cardioplegia from 2012 to 2019; = 542 patients.

Rule Out Acute Kidney Injury in the Emergency Department With a Urinary Dipstick.

Introduction: The identification of acute injury of the kidney relies on serum creatinine (SCr), a functional marker with poor temporal resolution as well as limited sensitivity and specificity for cellular injury. In contrast, urinary biomarkers of kidney injury have the potential to detect cellular stress and damage in real time.

Methods: To detect the response of the kidney to injury, we have tested a lateral flow dipstick that measures a urinary protein called neutrophil gelatinase-associated lipocalin (NGAL).
