description | Background: An intravenous infusion of lidocaine has been used on numerous occasions to produce analgesia in neuropathic pain. It has been shown to be beneficial for the treatment of variety of neuropathic pain states in a wide range of dosage, from 2 to 7.5 mg/kg. The aim of our study was to evaluate the efficacy of two different doses of intravenous lidocaine (3 and 4 mg/kg) in patients with chronic pain. Methods: Patients above the age of 18 years suffering from chronic pain due to postherpetic neuralgia, post-surgical scar pain, chronic low back pain having numeric analogue scale (NAS) pain score of ≥3 without satisfactory pain relief from conservative treatment were randomised to receive either 3 mg/kg or 4 mg/kg intravenous lidocaine in 250 mL normal saline infusions weekly over a period of 1 hour for 3 weeks. NAS was measured before starting each infusion, immediately after completion of infusion, 2 and 24 hours, 7th day, 14th day, 21st day, and 28th day. Results: NAS score at first hour and 24th hour was significantly reduced (P = 0.001), after each infusion [7th, 14th day] in both the groups. There was no statistical difference in pain score among both groups except for day 7 (P value 0.04). Reduction in NAS score was also present on 21st and 28th day in both groups, but it did not reach a significant value. On 28th day, NAS score values showed increasing trend. Duration of pain relief was around 1 week after each infusion in both groups. Conclusion: Intravenous lidocaine at a dose of 3 mg/kg or 4 mg/kg was effective in reducing pain in patients with chronic pain. The analgesic effect was not different among both groups. Trend of greater response was observed with 4 mg/kg dose. |
