Clinical Trial 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.

Description:

PPCs are defined as the occurrence within 2 days postoperatively of atelectasis unplanned ventilation, acute respiratory distress syndrome (ARDS), and postoperative pneumonia syndrome Unplanned ventilation postoperatively: Defined as the use of non-invasive mechanical ventilation, invasive mechanical ventilation, or extracorporeal membrane oxygenation (ECMO) after the first extubation postoperatively or if extubation cannot be performed as planned.

Acute Respiratory Distress Syndrome (ARDS): Defined as acute diffuse inflammatory lung injury leading to increased pulmonary vascular permeability, increased lung weight, loss of aerated lung tissue, hypoxemia, and bilateral opacities on imaging (using the Berlin Consensus definition).

Postoperative pneumonia: Defined according to the diagnostic criteria in the "Chinese Adult Hospital-Acquired Pneumonia and Ventilator-Associated Pneumonia Diagnosis and Treatment Guidelines" (2018 version): new or progressive infiltrates, consolidation, or ground-glass opacities on chest X-ray or CT, along with two or more of the following clinical symptoms: ① fever (> 38.0°C), ② purulent respiratory secretions, ③ peripheral blood leukocyte count > 10×10^9/L or < 4×10^9/L.

• Intraabdominal Infections
• Postoperative Pulmonary Complications

Intervention

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

Other	To observe the impact of continuous perioperative lidocaine infusion on the levels of neutrophil extracellular traps (NETs) postoperatively	Twenty patients from each group will be selected for blood collection before anesthesia, 24 hours postoperatively, and 7 days postoperatively, to explore the potential mechanisms influencing peripheral blood NETs levels	before anesthesia, 24 hours postoperatively, and 7 days postoperatively
Primary	The impact of continuous 24-hour intravenous lidocaine on the incidence of PPCs in patients undergoing emergency laparotomy for IAI.	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	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	The protection of important organ function during the perioperative period is defined as the difference in Sequential Organ Failure Assessment (SOFA) scores between the highest preoperative and postoperative 2-day scores (Delta-SOFA), following the "Sepsis 3.0 International Consensus on Sepsis and Septic Shock."	within 30 days postoperatively
