Efficacy Study of Ketamine for Postoperative Pain in Opioid Dependent Patients
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.

|Estimated Study Completion Date:||June 2012|
|Primary Completion Date:||June 2011 (Final data collection date for primary outcome measure)|
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.
IV ketamine 0.2 mg/kg/hr for 24-48 hours postoperatively.
Placebo Comparator: Placebo
Patients who received placebo recieved an infusion of saline.
Patients who received placebo were given saline infusions
