Key result
Ultrasonic cardiac output monitoring (USCOM) strongly correlated with echocardiography for measuring cardiac output in children after cardiac surgery (r=0.945; 95% CI 0.918-0.964; p<0.0001).

USCOM provides credible and accurate cardiac output measurements comparable to echocardiography in children after cardiac surgery, making it suitable for screening.
Supports USCOM for noninvasive screening in pediatric post-cardiac surgery; extends correlation data but leaves open need for prospective validation.
The objective: to assess the accuracy of cardiac output measurement by ultrasonic cardiac output monitor ( USCOM ) versus echocardiography ( ECHO ) in the children after cardiac surgery. Subjects and methods: A prospective observational trial was conducted (288 patients were assessed for eligibility, and data from 88 patients were analyzed). Cardiac output was measured by USCOM and ECHO . Results. The age of the patients was 305 ± 177 days. Cardiac output measured by USCOM , was 1.310 ± 0.605 [1.182; 1.438] L/m in, while the one measured by ECHO made 1.298 ± 0.608 [1.169; 1.427] L/m in. ANOVA demonstrated no statistically significant difference ( p = 0.89). A significant positive correlation was found between cardiac output rates measured by two methods (r = 0.945 [0.918, 0.964], p < 0.0001). The Blan d-A ltman plot demonstrated the shift of 0.012 ± 0.200 L/m in. and agreement limits from -0 .38 to 0.4 L/m in. There was no correlation between the shift and median values of cardiac output (r = -0 .015 [-0 .224, 0.195], p = 0.89). Conclusions. USCOM credibly measures the cardiac output versus the reference method of ECHO . Despite the known limitations, both methods can be used in children after cardiac surgery: USCOM − for screening, ECHO ‒ for deeper examination.

Леонов et al. (2018) conducted an observational in Children after cardiac surgery (n=88). Ultrasonic cardiac output monitor (USCOM) vs. Echocardiography (ECHO) was evaluated on Cardiac output (L/min) (r 0.945, 95% CI 0.918-0.964, p=<0.0001). Ultrasonic cardiac output monitoring (USCOM) strongly correlated with echocardiography for measuring cardiac output in children after cardiac surgery (r=0.945; 95% CI 0.918-0.964; p<0.0001).
