Objective: Pregnant women in the first trimester may be exposed to many surgical procedures that could not be postponed to delivery. Anesthesia selected in such patients may be regional or general. It has to be the best for early gestational sac oxygenation and perfusion. Power Doppler index is an accurate quantitative method for evaluation of blood flow of the gestational sac; it is a noninvasive transabdominal method. Methods: This study was conducted on 20 pregnant women who underwent surgical procedures in the first trimester. They were divided in 2 equal groups; group 1 received general anesthesia (isoflurane-fentanyl), and group 2 received spinal anesthesia. Three dimensional Transabdominal power Doppler measurement of subtrophoblastic blood flow index was done for all studied women before and after both types of anesthesia. Results: Subtrophoblastic blood flow index was significantly higher in general anesthesia group 13(0.7) compared to spinal anesthesia group 10.3(0.9) (p < 0.001).Conclusion: Subtrophoblastic blood flow index decreased in spinal anesthesia more than general anesthesia. The use of transabdominal three-dimensional power Doppler ultrasonographic imaging of the subtrophoblastic blood flow may be helpful for evaluation of the effect of different anesthetics on subtrophoblastic blood flow.
