Various studies report conflicting data with regard to the level of risk of cesarean delivery for nulliparous women who receive epidural analgesia before 5 cm of cervical dilatation. As a result, some institutions are requiring that laboring women reach 4-5 cm of dilatation before receiving epidural analgesia. The American College of Obstetricians and Gynecologists wishes to reaffirm the opinion published jointly with the American Society of Anesthesiologists that while under a physician's care, in the absence of a medical contraindication, maternal request is a sufficient medical indication for pain relief during labor. Decisions regarding analgesia should be coordinated among the obstetrician, the anesthesiologist, the patient, and support personnel.
