Abstract

Objective: To assess the effects of lidocaine infusion on postoperative pain.
Methodology: Our study was done on 40 patients between the ages of 25-45 years who were previously healthy and underwent various abdominal surgeries. Patients were classified into case (A) and control (B) groups with randomized double blind fashion. Calculations of intra- and post-operative morphine consumption were done and pain was verbally assessed according to Visual Analogue scale (VAS) using pain score of 10. In group A 2% lidocaine was given in a dose of 1.5 mg/kg bolus IV half hour before induction followed by IV infusion 1.5mg/kg/hr before skin incision). InGroup B, saline was given.
Results: The scale of pain among group A was significantly less in comparison to group B.
Conclusion: Our study was consistent with previous studies about lidocaine, which showed significant decrease in pain by using lidocaine infusion.

Key words: Lidocaine, pain, morphine consumption, abdominal surgeries, infusion.
