  Purpose

Patients who are dependent on opioids often have poor pain relief after major surgery. This study tests the hypothesis that adding intravenous ketamine to a postoperative regimen of intravenous opioids for postoperative pain will improve pain relief in this subset of patients.

Arms Assigned Interventions
Active Comparator: Ketamine
Ketamine is being compared to the use of placebo, in addition to intravenous opioids, for postop pain control in opioid dependent patients who undergo major surgery.
Drug: Ketamine
IV ketamine 0.2 mg/kg/hr for 24-48 hours postoperatively.
Placebo Comparator: Placebo
Patients who received placebo recieved an infusion of saline.
Drug: Placebo
Patients who received placebo were given saline infusions
