A new classification system for the radial-arterial pressure-wave contour in children is proposed with respect to their hemodynamic parameters. The contour of the radial-arterial pressure wave was analyzed in 45 children who had undergone open heart surgery. Stroke volume and peripheral vascular resistance were calculated from the cardiac output by thermodilution. The arterial pressure-wave contours were classified into type I, II or III, with each wave type having three, two and one shoulders, respectively. Type I denoted a better cardiac index, with a lower heart rate and larger stroke volume than type II. Type III was symptomatic of low cardiac output. Type I was further classified into subgroups Ia and Ib according to the magnitude of the tidal wave, and type II was subdivided into IIa and IIb according to the magnitude of the dicrotic notch. The classification of subgroup types a and b in both types I and II was related to the degree of vascular contraction. It is concluded that monitoring of the arterial pressure-wave contours provides useful information regarding hemodynamics in children.
