Some physicians are reluctant to provide women with an epidural if they are dilated eight or more centimeters. Their thinking is that toward the end of labor, due to the intensity of your contractions, it may be difficult for you to sit still for placement of the epidural, or that the birth may take place before the numbing medication has a chance to work (this may be true, but if it is not the case, and your labor continues, the medication can provide much needed relief). With effort and support of your caregivers, it is possible, although often challenging, to remain in position long enough to receive an epidural for the short remainder of your labor. Many anesthesiologists are willing to give a woman an epidural upon her request, until she has reached the point where the baby's head is crowning (visible).
