NCT06304779

Brief Summary

The main purpose of this study is to evaluate the impact of continuous 24-hour intravenous infusion of lidocaine on the incidence of PPCs in patients undergoing emergency laparotomy for intra-abdominal infection (IAI).The secondary objectives of this study are to assess the impact of continuous 24-hour intravenous lidocaine infusion on the proportion of patients requiring mechanical ventilation, protection of important organ function during the perioperative period, length of hospital stay, and outcomes within 30 days postoperatively.

Outcome Measures

Primary Outcomes (1)

  • The incidence of PPCs in patients undergoing emergency laparotomy for IAI with or without continuous 24-hour intravenous lidocaine.

    PPCs are defined as a syndrome encompassing atelectasis, unplanned mechanical ventilation, acute respiratory distress syndrome (ARDS), and postoperative pneumonia occurring within 2 days after surgery.

    within 2 days after surgery

Secondary Outcomes (1)

  • Proportion of patients requiring mechanical ventilation and protection of important organ function during the perioperative period: with versus without continuous 24-hour intravenous lidocaine infusion.

    within 30 days postoperatively

Other Outcomes (1)

  • Comparison of postoperative levels of neutrophil extracellular traps (NETs) in patients with or without continuous perioperative lidocaine infusion.

    before anesthesia, 24 hours postoperatively, and 7 days postoperatively

Study Arms (2)

Control group

PLACEBO COMPARATOR

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

Drug: Placebo

Lidocaine group

EXPERIMENTAL

Patients 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.

Drug: Lidocaine

Interventions

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.

Lidocaine group

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