The Effect of Gabapentin, Ketamine and Dexamethasone on Pain and Opioid Requirements After Hip Surgery

Brief Summary

Patients scheduled for primary hip replacement needs postoperative pain treatment, i.e. morphine. Morphine has side-effects: nausea, vomiting, sedation and dizziness. These side-effects are unpleasant for the patients and sometimes keeps them at bed longer time than needed. We investigate in new combinations of analgesics for postoperative pain, hoping to minimize the need for morphine.

    Comparing analgesic effect of gabapentin 1200 mg + dexamethasone 8 mg + ketamine 0.15 mg/kg
  • Placebo (DRUG)
