Comparison of the Ultrasonic Cardiac Output Monitor and Echocardiography for Hemodynamic Assessment in Pediatric Anesthesia: A Prospective Observational Study

J Cardiothorac Vasc AnesthPublished Prospective observational study

Authors' conclusion

Even when measurements were obtained from the same suprasternal window under controlled intraoperative conditions, USCOM systematically overestimated flow-derived parameters and markedly inflated stroke volume variation compared with echocardiography.

Study context

Population
Children aged 6 months to 15 years, ASA I–II, undergoing elective surgery under standardized GAmedian age 7 years
Participants
57 children
Exposure
Ultrasonic Cardiac Output Monitor (USCOM) vs Echocardiography
Outcome
Agreement in stroke volume, velocity time integral, aortic valve area and stroke volume variation (mean of 3 consecutive measurements)
Follow-up
After induction and hemodynamic stabilization
Methodological detailssingle-centre, method comparison
  • Single-centre
  • Method comparison

Main finding

As reported in the abstract

  • USCOM produced higher stroke volume and velocity-time integral values than echocardiography
  • Aortic valve area estimates similar
  • Stroke volume variation markedly higher with USCOM, with wide limits of agreement

Observational data: associations, not effects.

Further findings

Fluid responsiveness classification (stroke volume variation threshold 12%)

USCOM classified most patients as fluid responsive; echocardiography identified substantially fewer above the cutoff
