Abstract
Epidural analgesia has been extensively used to provide pain relief during labor.Labor pain and painful uterine contractions cause hyperventilation and high catecholamine levels, resulting in maternal and fetal hypoxemia. Pain relief provides a comfort for the patients and attenuates the release of stress hormones. Epidural bupivacaine is still the most widely used local anesthetic in obstetric analgesia. Many drugs are added to bupivacaine to minimize its total dose and to prolong the analgesic effect.
