The Effect of Continuous Intravenous Infusion of Lidocaine on PPCs and Prognosis in Emergency Surgical Patients With IAI
The Effect of Continuous Intravenous Infusion of Lidocaine on Postoperative Pulmonary Complications and Prognosis in Emergency Surgical Patients With Intra-abdominal Infection
Study Overview
Status
Intervention / Treatment
Detailed 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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: Control group
Patients receive an equivalent volume of normal saline at anesthesia induction and throughout the perioperative period until 24 hours postoperatively.
|
atients receive an equivalent volume of normal saline at anesthesia induction and throughout the perioperative period until 24 hours postoperatively.
|
Experimental: Lidocaine group
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.
|
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. |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The impact of continuous 24-hour intravenous lidocaine on the incidence of PPCs in patients undergoing emergency laparotomy for IAI.
Time Frame: within 2 days after surgery
|
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 Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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
Time Frame: within 30 days postoperatively
|
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
|
Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To observe the impact of continuous perioperative lidocaine infusion on the levels of neutrophil extracellular traps (NETs) postoperatively
Time Frame: before anesthesia, 24 hours postoperatively, and 7 days 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
