[Current approaches to the analgesia of spontaneous child birth]

Abstract

The authors have compared various modes of spontaneous labor. Prolonged epidural infusion of naropine in combination with fentanyl has been found to cause a less motor block and therefore it may be used in the late first-to-second period of labor. Adequate analgesia ensures a smooth course of the second labor period and promotes the reduction in its duration and the correction of central hemodynamic and hormonal homeostastic disorders. The administration of moradol provides adequate analgesia of the first labor period, prevention, and elimination of abnormal labor activity, without exerting a depressive effect on maternal and neonatal respiration, which makes it possible to consider this procedure as an alternative mode of labor pain relief if there are contraindications to epidural analgesia.
