Prevention of reoxygenation injury in hypoxaemic immature hearts by priming the extracorporeal circuit with antioxidants.

Abstract

This study tests the hypothesis that abrupt reoxygenation of cyanotic immature hearts when starting cardiopulmonary bypass produces an unintended reoxygenation injury that: (i) nullifies the cardioprotective effects of blood cardioplegia; and (ii) is avoidable by adding the antioxidants, N-(2-mercaptopropionyl)-glycine (MPG) plus catalase to the… (More)
