[Microcirculatory dysfunction after cardiac surgery: Interest of NIRS technology with two case reports]

Abstract

Near infrared spectroscopy (NIRS) seems to be an interesting technology to study microcirculatory dysfunction. These alterations have been described after cardiac surgery under cardiopulmonary bypass. We report two case study reports with monitoring of StO(2) and reperfusion slope after an ischemic challenge. These two parameters are early altered notably in case of cardiac dysfunction (decrease of StO(2) and reperfusion slope). We discuss the interest of microcirculatory measurement in this context.
