- Abstract
The objective of this study was to evaluate a new bioreactance method for noninvasive cardiac output (CO) measurement (NICOM) in children. Ten patients between 1 and 144 months of age and with no hemodynamic disturbances were studied. Using bioreactance, heart rate (HR), mean arterial pressure (MAP), and cardiac index (CI) measurements were made every 6-8 h. CI was 2.4 ± 1.03 l/min/1.73 m (range 1-4.9 l/min/1.73 m); There were significant correlations between CI and age ( r = 0.50, P = 0.003), weight ( r = 0.66, P < 0.001), and MAP ( r = 0.369, P = 0.037). Significant differences in CI ( P < 0.001) were detected between children weighing <10 kg (1.9 ± 0.73 l/min/1.73 m; range 1-3.2), 10-20 kg (2.07 ± 0.7 l/min/1.73 m; range 1-3.6), and >20 kg (3.7 ± 0.8 l/min/1.73 m; range 2.4-4.9). We conclude that the CI measured by bioreactance in children varies with the age and weight of the patients and is lower than the normal range in a large percentage of measurements. These data suggest that this method is not useful for evaluating CI in small children.
