Summary
Patients with a daily use of opioids may develop higher postoperative pain levels, often need
high doses of morphine and therefore their pain may be difficult to treat. A low dose of an
old anesthetic drug, ketamine, administered during surgery can possibly reduce pain and
morphine consumption in these patients. Our purpose is to investigate the effect of low dose
ketamine on morphine consumption and pain after spine surgery in patients with a daily use of
opioids. Our hypothesis is that low dose ketamine can reduce morphine consumption, pain and
side-effects after spine surgery.
