[Cardiac output measurement with transtracheal Doppler in children].
Cardiac output (CO) measurement with transtracheal Doppler (TTD) was compared with that measured by transthoracic electrical bioimpedance (TEB) in normal children, and with that by thermodilution (TD) in children with heart disease. In CO measurement, TTD correlated significantly with TD (r = 0.65, P < 0.05), but not with TEB. Although aortic diameters, which were necessary for CO measurement with TTD, were far from the values in Woezik's nomogram of normal children, they correlated significantly with those measured from angiographies in children with heart disease (r = 0.92, P < 0.05). However, it is assumed that the significant correlation of diameters in children with heart disease might be produced by the offset of measurement errors in position and angle of the Doppler probe.
