The purpose of this study is to evaluate the superiority of IV lidocaine combined with morphine spinal anesthesia versus placebo combined with morphine spinal anesthesia, in reducing postoperative morphine consumption at 48 hours, in patients undergoing major digestive or abdominal surgery by laparotomy.
This is a prospective, interventional, comparative, randomized, 2-group parallel, placebo-controlled, double-blind, single-center trial designed to evaluate the value of intravenous lidocaine combined with morphine rachi anesthesia in major laparotomy digestive or abdominal surgery. The study corresponds to a clinical trial of a medicinal product in compliance with Regulation (EU) n°536/2014. The study population is composed of adult patients receiving morphine spinal anesthesia for major laparotomy surgery and who have signed an informed consent form.
