Intravenous injection of lignocaine relieves pain in animals with experimentally induced pain, and in man, mainly those with neuropathic pain. 106 patients were treated with intravenous lignocaine during a period of 18 months (212 treatment sessions). Blood pressure, heart rate and pain scores were continuously monitored after an intravenous bolus of lignocaine, 1 mg/kg, followed by continuous infusion of lignocaine, 5 mg/kg during 1 hour. There was significant pain relief after each session in most patients, lasting from a few hours to 4 weeks. There were no significant side effects. We present 2 of our patients. Due to its simplicity, efficacy and safety, intravenous lignocaine injection is recommended for those with neuropathic pain unrelieved by other therapeutic modalities.
