Brief Summary

Epidural anesthesia (EP) is widely used for labor analgesia. Time to onset of adequate pain relief of EP technique for labor analgesia may be 15 to 20 minutes.More rapid injection is often passible through the needle compared to catheter and could enhance the spread of medication within the epidural space.There is lack of research assessing the onset of labor analgesia with a large priming dose of local anesthetic through the epidural needle compared with the epidural catheter.
