TRANSCRIPT OF ANSWER
Spinal anesthesia is used in the labor and delivery unit, most commonly for a cesarean section. The shortcoming of spinal anesthesia is that it is time-limited, so we don’t use it for Labor analgesia because it is difficult to predict how long labor will take. Most spinal anesthetics will wear off within three hours. So if you have a scheduled c-section, or you have not had any prior anesthesia, such as an epidural placed, your anesthesia team may opt for a spinal anesthetic as the mechanism to keep you comfortable during the cesarean delivery.
