Usefulness of the maximum rate of pressure rise in the central and peripheral arteries after weaning from cardiopulmonary bypass in pediatric congenital heart surgery A retrospective analysis

摘要

The maximum rate of pressure rise (dP/dt(max)) in radial artery has been proposed as a noninvasive surrogate of aortic dp/dt(max), reflecting left ventricular (LV) contractility in children. The aim of this study was to investigate relationship between aortic and radial dp/dt(max) at weaning from cardiopulmonary bypass (CPB) and usefulness of these indices for estimating postoperative outcomes in pediatric congenital heart surgery.
