Brief Summary:
This study hypothesizes that the addition of a low-dose ketamine infusion to usual post-operative pain management will improve pain control as evidenced by an improvement in post-operative pain scores for patients undergoing spinal fusion for idiopathic scoliosis.

Condition or disease Intervention/treatment Phase
Idiopathic Scoliosis Post-operative Pain Drug: Ketamine Other: Placebo Phase 4

Detailed Description:

After consenting, patients will be randomized by the pharmacy. In the operating room patients will receive ketamine/placebo 0.5mg/kg bolus prior to the surgical incision, followed by ketamine/placebo 0.2mg/kg continuous infusion up to 48hours. All the patients will also receive 15mg/k IV acetaminophen at the end of the surgery, followed by every 6hr for 48hrs. Rest of the pain regimen will be the usual post-operative pain management for spinal fusion for idiopathic scoliosis, which includes morphine PCA, IV ketorolac from POD 1, and flexaril from POD 1.

All the patients and parents will fill out a survey at 0hr, 24hr and 48hr grading their level of satisfaction with the post-operative pain.

Drug Information available for: Ketamine

Arm Intervention/treatment
Experimental: Treatment Group
A ketamine bolus of 0.5mg/kg will be given and then the ketamine infusion of 0.2 mg/kg/hr will be initiated prior to incision. Intra-operative opioids will be at the discretion of the attending anesthesiologist. Postoperative management will include continuation of the study drug as well as a standardized morphine patient-controlled analgesia (PCA) and acetaminophen 15 mg/kg IV every 6 hours. On postoperative day 1, patients are started on ketorolac 0.5 mg/kg up to 15 mg IV q8h. On postoperative day 2 they are transitioned to ibuprofen 10 mg/kg up to 600 mg. The ketamine infusion will continue for 48 hours post operatively at which point the PCA is discontinued and patients are transitioned to oral pain medications (Roxicet or Lortab and Flexeril) as per the current protocol.
Drug: Ketamine
Placebo Comparator: Placebo
A placebo (saline) will be given in place of ketamine
Other: Placebo
Other Name: Saline

Primary Outcome Measures :
  1. Patient Satisfaction [ Time Frame: Through study completion, 48 hours ]
    All the patients and parent will fill out a survey grading their level of satisfaction with their post-operative pain management

Secondary Outcome Measures :

    Pain scores will be collected from the nursing sheet

  2. Opioid Use [ Time Frame: Through study completion, 48 hours ]
    Total Morphine consumption will be collected from PCA data

  3. Length of Stay [ Time Frame: Through study completion, 48 hours ]
    Length of hospital stay from surgery to discharge
