NCT00808665

Brief Summary

Major lumbar spine surgery causes inflammation, soreness and swelling that can delay discharge from the hospital. Dexmedetomidine (DEX) has been shown to have anti-inflammatory effects. This study will evaluate whether DEX can help get patients out of the hospital faster after major spine surgery by reducing the inflammation associated with the procedure itself. A separate part of the study will evaluate the blood levels of some specific indicators of inflammation called cytokines. Measuring cytokines before and after surgery will aid in determining if DEX has altered the inflammatory response.

Outcome Measures

Primary Outcomes (1)

  • Time Required After Surgery to Reach Fitness for Discharge From Hospital

    Start of study drug to time to reach fitness for discharge from hospital (about 3 to 5 days)

Study Arms (2)

Dexmedetomidine

EXPERIMENTAL

At the beginning of spinal surgery, patients will receive 1 hour dexmedetomidine intravenous bolus of 0.7 mcg/kg, followed by infusion of dexmedetomidine at a rate of 0.5 mcg/kg/hour for 2 hours, followed by an infusion of dexmedetomidine at a rate of 0.2 mcg/kg/hour for the duration of the procedure and for 4 hours after the procedure.

Drug: Dexmedetomidine

Saline

PLACEBO COMPARATOR

Since this is a blinded study, at the beginning of spinal surgery, patients will receive a 1 hour 0.9% saline intravenous bolus at a rate and volume commensurate with a 0.7 mcg/kg/hour bolus of dexmedetomidine. Similarly, this will be followed with a saline infusion at a rate of 0.5 mcg/kg/hour for 2 hours, followed by an infusion of saline at a rate of 0.2 mcg/kg/hour for the duration of the procedure and for 4 hours after the procedure.

Drug: 0.9% Saline

Interventions

Patients will be given 0.7 mcg/kg/hr of dexmedetomidine over the first hour of surgery, followed by continuous infusion of 0.5 mcg/kg/hr of dexmedetomidine for the next 2 hours of surgery. Dexmedetomidine dose will be reduced to 0.2 mcg/kg/hr for the duration of the procedure and continued at that rate for four hours postoperatively. Patients in the placebo arm will receive an equal per-kg IV volume of 0.9% Sodium Chloride over the same periods. Drug administration will be controlled for both arms of the study using a continuous infusion pump.

Also known as: Precedex
Dexmedetomidine

Patients in the placebo arm will receive an equal per-kg IV volume of 0.9% Sodium Chloride over the same periods. Drug administration will be controlled for both arms of the study using a continuous infusion pump.
