Description of intervention(s) / exposure
The effect of intravenous ketamine given prior to and for up to 24 hours following surgical incision on the prevalence and severity of chronic post-surgical pain at 4-6 months postoperatively. Ketamine dosage is 0. 5mg/kg bolus, followed by 0.25 mg/kg/hr intra-operatively. then 0.1 mg/kg/hr continued for 24 hour

Summary
Brief summary
There is a well established physiological basis for the proposition that a potent NMDA receptor antagonist such as the widely available drug ketamine given peri-operatively may reduce the development of chronic postsurgical pain in patients undergoing major surgery, and this proposition is supported by available data pooled from small placebo controlled published studies, and a large study on N2O. The potential benefits of this in reducing the burden of chronic pain in the community are substantial.
A large multicentre randomized trial is needed in patients undergoing major surgery to determine whether chronic post-surgical pain is reduced using intravenous ketamine given peri-operatively.
