Study Arms:
- Patient Controlled Analgesia (Type: ACTIVE_COMPARATOR): One group will have a patient controlled device connected to an intravenous patient controlled analgesia (IV PCA). This device runs a basal infusion of pain medicine (morphine) intravenously with additional allowable patient controlled doses every 10 minutes.
- epidural Catheter (Type: ACTIVE_COMPARATOR): The other group will have an epidural catheter inserted under sterile conditions in the thoracic epidural space after anesthesia has been induced. This will be connected to a patient controlled epidural analgesia (PCEA) device for postoperative pain control that works in a similar manner except the medication (a combination of local anesthetics and hydromorphone) will be administered in the thoracic epidural space.

Based on this trial design, predict the completion outcome and termination type (if applicable).
