3 The current scientific literature is also inadequate to inform patients or physicians whether anesthesia may have adverse neurodevelopmental effects on the fetus during pregnancy.
ASA Practice Advisory for Preanesthesia Evaluation concluded that the scientific literature is inadequate to inform patients or physicians on whether anesthesia causes harmful effects during pregnancy. No currently used anesthetic agents have been shown to have any teratogenic effects in humans of any age when using standard clinical doses and duration. These may take the form of x-rays or teratogenic medications. 1Īdditional consideration for preoperative screening should be made if the procedure is expected to expose a fetus to potential teratogens. Intra-abdominal laparoscopic procedures have indeterminate fetal risk. Surgeries disrupting uterine blood flow include procedures involving the heart and vascular system including the aorta, common iliac arteries, internal iliac arteries, uterine arteries, and ovarian arteries. Uterine surgeries include dilation and curettage, hysteroscopy, endometrial ablation, myomectomy, and hysterectomy.
Surgeries involving the uterus and uterine cavity and procedures disrupting uterine blood flow place the fetus at high-risk. Surgical indications for preoperative pregnancy screening should be based upon risk for fetal harm during, or subsequent to, the surgical procedure.
