The application of intravenous lidocaine in general anesthesia of patients with gastrointestinal tumors

Abstract

Lidocaine is often used for local anaesthesia and nerve block. Intravenous lidocaine can reduce intracranial pressure and exert brain protection in neurosurgery. With the continuously deepening clinical research and application of lidocaine, the effects of lidocaine on analgesia, anti-inflammatory, organ protection and promotion of postoperative recovery in general anesthesia are also gradually attracting attention. The patients with digestive tract tumors are mostly middle-aged and elderly. Because of long-term malnutrition and hemorrhage of tumors, the patients suffer from hypoproteinemia, emaciation, anemia, systemic organ failure, poor tolerance to surgery and anesthesia, intraoperative and postoperative prone to hemodynamic instability, poor oxygenation, delirium, cognitive dysfunction, pain and so on. This article reviews the application of intravenous lidocaine in general anesthesia of patients with gastrointestinal tumors, aiming to optimize the intraoperative management and improve the prognosis of patients.
