[Changes in the hypophyseal-thyroid system under narcotic action in the parturients of a group at high risk of perinatal pathology].

Eighty-seven parturients were examined to disclose the function of the thyroid during narcotic exposure in labor and in cesarean section in cases of high risk of giving birth to infants with perinatal abnormalities. Neurotropic agents were found to inhibit the fetal hypophyseo-thyroid system in cases with a history of intrauterine hypoxia, thus saving this system from exhaustion. Employment of various types of general anesthesia in cesarean section in this patient population provides an adequate maternal neurovegetative protection from surgical aggression.
