 If the patient does not obtain relief within 30 minutes, the epidural catheter will be dosed with a local anesthetic and the study will be concluded. The patients without pain relief within 30 minutes are considered to have failed epidurals and are dropped from the study and the analysis. Following achievement of satisfactory analgesia, the patient will be evaluated every 30 minutes until they request additional analgesics. The study will end at this point, and the patient will be treated at the discretion of the anesthesiologist.
