NPPB and coronary artery disorder: By monitoring children with CHD during the first 48 post-CPB hours using PRAM, we found the followings: (1) systemic hemodynamics and myocardial status gradually improved without the “classic” nadir at 9–12 h; (2) patients undergoing DHCA had significantly higher heart rate and lower CCE; (3) higher epinephrine doses were adversely associated with overall systemic hemodynamics and myocardial performance, indicated by lower SBP, CI, dP/dTmax and CCE, and higher heart rate, DBP, SVRI, lactate, and NT-proBNP; (4) CCE was the most sensitive and consistent indicator among all PRAM parameters.
