Key result
Simultaneous Doppler and echocardiography detects a 29% incidence of venous air emboli during cesarean section.
Why the study?
Are Doppler-detected venous emboli during cesarean section air emboli, and how does Doppler correlate with two-dimensional echocardiography?
Observational (n=49)
Are Doppler-detected venous emboli during cesarean section air emboli, and how does Doppler correlate with two-dimensional echocardiography?
Effect estimate: kappa = 1
Venous emboli during cesarean section are relatively common (29%) and are confirmed by echocardiography to be air emboli rather than amniotic fluid or thromboemboli.

Supports air embolism vigilance in cesarean anesthesia; confirms Doppler-echocardiography correlation but leaves open clinical utility.
Fong et al. (1990) conducted an observational in Cesarean section (n=49). Simultaneous precordial ultrasonic Doppler monitoring and two-dimensional echocardiography was evaluated on Incidence of venous emboli and correlation between Doppler and echocardiography (kappa = 1). Simultaneous Doppler and echocardiography monitoring during cesarean section detected a 29% incidence of venous emboli, which were confirmed to be air emboli with perfect correlation (kappa = 1).
