The Effect of Continuous Intravenous Infusion of Lidocaine on PPCs and Prognosis in Emergency Surgical Patients With IAI

"Lidocaine group receive a loading dose of 1.5 mg/kg 2% lidocaine at anesthesia induction, followed by continuous intravenous infusion at 1.5 mg/kg/h until 24 hours postoperatively and Control group receive an equivalent volume of normal saline at anesthesia induction and throughout the perioperative period until 24 hours postoperatively.~Both groups will receive the same anesthesia and postoperative analgesia protocols, lung-protective ventilation strategy, and fluid, transfusion, and warming strategies. The only difference is the intervention during surgery, with the lidocaine group receiving continuous intravenous lidocaine."

atients receive an equivalent volume of normal saline at anesthesia induction and throughout the perioperative period until 24 hours postoperatively.
