Major abdominal surgery continues is one of the most performed surgical procedures in the world, both electively and urgently. One of the main problems of this type of intervention is postoperative pain. it is shown that it increases health costs related to longer recovery times, longer hospital stay and related complications such as the increased risk of presenting chronic POP pain, which it has been estimated up to 20%, much higher if the surgery involves surgery in the gastrointestinal system.

The goal of analgesia in the postoperative setting is precisely to provide comfort to patients, minimize adverse effects and complications arising from the procedure.

The epidural analgesic technique (has been proposed as an analgesic management standard, since multiple studies have shown that it reduces opioid consumption, improves recovery and is a useful strategy for pain control. However, it is an invasive technique, with risk of complications such as hematomas and epidural abscesses, and it may be difficult to perform.

Currently it has been shown in multiple studies that the intravenous infusion of a local anesthetic, such as lidocaine, in this type of surgical scenarios can reduce the intensity of pain, opioid consumption, hospital stay and ileus with few adverse effects. In addition, these studies propose that, being a less invasive technique, it could be easier to implement and even be safer than the epidural technique.

The main hypothesis of this study is precisely that the infusion of lidocaine may be non-inferior to epidural analgesia in the analgesic management of patients undergoing major abdominal surgery.
