Randomization will be performed by the research pharmacy. Subjects will be randomized in blocks of four. Upon arrival in the OR the anesthesiologist will open an envelope which will demonstrate the number medication the patient will receive based on a blinding key which the pharmacy will possess. At minimum, 6 sets of vials of either placebo or ketorolac will be held in the drug dispensary at any given time. The anesthesiologist or anesthetist will then pull the drug from the dispensary. Once the fetus is delivered and the cord is clamped, the drug will be administered by the anesthesiologist or anesthetist. Any additional medications required for sedation or pain control during the remainder of the surgery (ketamine, hydromorphone, acetaminophen) will be given, as appropriate for patient comfort. Prior to completion of procedure the patient will receive epidural morphine sulfate per the standard protocols used in MacDonald Women's Hospital. Postoperatively, the patient will receive 3 additional scheduled doses of ketorolac 6 hours apart and intravenous hydromorphone, as needed for pain control.
