The rate of cesarean delivery after epidural analgesia for labor has not been reported in our institute. The aim of this study is to elucidate incidence of cesarean delivery in parturient whom received epidural analgesia. Besides, factors associated with the rate of cesarean delivery were studied.
Epidural analgesia with local anesthetic and opioid is the efficiently good method to relieve labor pain comparing with intravenous opioid analgesic. Many literatures reported effects epidural analgesia for labor eg. prolonging the duration of second stage of labor, increasing the rate of instrumental delivery: vacuum extraction and forceps assisting labor. Some papers revealed the increasing in the rate of cesarean delivery. The main reason is assume to be a failure to progress labor after epidural analgesia. However, the recent report from Cochrane database systematic review showed no relation of epidural analgesia for labor and the increasing in the rate of cesarean delivery. Various factors that may involve in the increasing in the rate of cesarean delivery including the dilatation of cervix at the time of insertion of epidural catheter, nulliparous, size of the fetus or motor weakness after receiving epidural medication.
