The effect of intravenous lidocaine infusion on the pain after laparoscopic assisted distal gastrectomy

This study tests whether giving a continuous intravenous (IV) drip of lidocaine (a local anaesthetic) during and after laparoscopic stomach surgery (laparoscopic assisted distal gastrectomy) reduces post-operative pain. Previous research has shown lidocaine infusions can reduce pain, painkiller needs, and stress responses after various types of surgery. Researchers want to find out if this also works for stomach surgery.
