Key result
Precordial Doppler detects venous air embolism in ~65% of cesarean deliveries, typically with decreased SaO2.
Why the study?
Venous air embolism is a rare but potentially serious complication of cesarean delivery with unclear incidence and relation to oxygen saturation and ECG changes.
What is the incidence of venous air embolism detected by precordial Doppler monitoring during cesarean delivery?
Observational (n=78)
What is the incidence of venous air embolism detected by precordial Doppler monitoring during cesarean delivery?
Precordial Doppler monitoring demonstrates a surprisingly high incidence (65%) of venous air embolism during cesarean delivery, occasionally leading to significant oxygen desaturation and ECG changes.
No takes yet. Share an insight, caveat, or question.
VAE Doppler signals common in cesarean with frequent desaturation; hypothesis-generating for monitoring, needs prospective trials before practice implications.
Vartikar et al. (1989) conducted an observational in Cesarean delivery (n=78). Precordial Doppler monitoring was evaluated on Incidence of venous air embolism (VAE) indicated by Doppler changes. Precordial Doppler monitoring during cesarean delivery detected changes consistent with venous air embolism in 65% (51 of 78) of patients, with 72% of these showing decreased SaO2.
