Summary
Brief summary (as posted)
This is a randomized, double-blinded, placebo-controlled, cross-over trial examining the effect of a series of two weekly intravenous infusions of lidocaine 4 mg/kg and ketamine 0.2 mg/kg in patients with moderate to severe opioid-refractory chronic cancer-related pain. The aim of this study is to investigate whether the lidocaine - ketamine (LK) regimen provides better analgesia that an active placebo of midazolam 0.02 mg/kg, in this population.
