Key result
Thermodilution and pulsed Doppler ultrasound reliably detected the significant increase in cardiac output induced by cross-clamping of the descending thoracic aorta in pigs.

Thermodilution and pulsed Doppler ultrasound are reliable clinical methods for detecting the significant increase in cardiac output induced by cross-clamping of the descending thoracic aorta.
Aadahl et al. (2000) studied Cross-clamping of the descending thoracic aorta (n=10). Thermodilution and pulsed Doppler ultrasound vs. Transit-time ultrasound flowmetry was evaluated on Cardiac output at 15 minutes following cross-clamping (p=<0.05). Thermodilution and pulsed Doppler ultrasound reliably detected the significant increase in cardiac output induced by cross-clamping of the descending thoracic aorta in pigs.
