Randomized Controlled TrialA Double-Blinded, Randomized, Placebo-Controlled Clinical Trial of Aminophylline to Prevent Acute Kidney Injury in Children Following Congenital Heart Surgery With Cardiopulmonary Bypass.
Acute kidney injury occurs commonly in children following congenital cardiac surgery with cardiopulmonary bypass and has been associated with increased morbidity and mortality. Aminophylline, a methylxanthine nonselective adenosine receptor antagonist, has been effective in the management of acute kidney injury in certain populations. This study sought to determine whether postoperative administration of aminophylline attenuates acute kidney injury in children undergoing congenital cardiac surgery with cardiopulmonary bypass. ⋯ In this placebo-controlled randomized clinical trial, we found no effect of aminophylline to prevent acute kidney injury in children recovering from cardiac surgery performed with cardiopulmonary bypass. Future study of preoperative aminophylline administration to prevent acute kidney injury may be warranted.

Randomized Controlled TrialThe Effect of Methylprednisolone on Plasma Concentrations of Neutrophil Gelatinase-Associated Lipocalin in Pediatric Heart Surgery.
Plasma neutrophil gelatinase-associated lipocalin is a kidney injury marker used in pediatric heart surgery. Neutrophil gelatinase-associated lipocalin is also a constituent of specific granules of neutrophils. Corticosteroids are widely used in pediatric heart surgery. Methylprednisolone inhibits degranulation of neutrophil-specific granules. Use of corticosteroids has not been taken into account in studies of neutrophil gelatinase-associated lipocalin in pediatric heart surgery. We studied the influence of systemically administered methylprednisolone on plasma neutrophil gelatinase-associated lipocalin concentrations in pediatric heart surgery. ⋯ Preoperatively administered methylprednisolone profoundly decreases plasma neutrophil gelatinase-associated lipocalin levels. Neutrophil gelatinase-associated lipocalin seems to originate to a significant extent from activated neutrophils. Preoperative methylprednisolone is a confounding factor when interpreting plasma neutrophil gelatinase-associated lipocalin levels as a kidney injury marker in pediatric heart surgery.
