[Intravenous lidocaine in the treatment of chronic pain caused by bone metastases].

A controlled double-blind investigation was undertaken in which ten patients with painful bone metastases were treated with intravenous lignocaine in a dosage of 5 mg/kg body-weight infused over a period of 30 minutes or the same volume of isotonic saline. None of the patients experienced prolonged pain relief but five patients experienced considerable pain relief immediately and/or one hour after the infusion of lignocaine.
