Abstract Developments and knowledge of the structure and dynamic function of the placenta during the last century as well as the appearance of various techniques to assess fetal evaluation; eventually encouraged physicians to acknowledge the potential fetal problems associated with administration of anesthetic drugs not only during delivery but a variety of obstetric and non-obstetric indications exist that lead to exposure of both the pregnant mother and her fetus to anesthesia. The anesthesiologist must consider the potential impact of surgery and anesthesia on fetal well-being, the potential for fetal exposure to teratogens among the anesthetic agents and other drugs administered perioperatively, the fetal risk for harmful alterations in uteroplacental perfusion and oxygenation, and risk of preterm delivery. Additional concerns are whether surgery and anesthesia during early gestation pose hazard to the developing fetus, by increasing the risk of congenital anomalies and spontaneous abortion. |
