Condition of the vegetative nervous system (VNS) of 120 pregnant women, which had effective labor pain releif have been studied. Among them 70 patients had medication analgesia, 50 patients had epidural anaesthesia (EDA), 40 — had no special labor pain releif. It is detected, that women with a balanced VNS activity could have just a phychological aid or minimum medication labor pain releif. Parturient women, which have strain of sympathetic part of the VNS, should be applied more effective methods of labor pain releif (medication or epidural anaesthesia).
