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

Postoperative Pulmonary Complications Clinical Trial

Official title: The Effect of Continuous Intravenous Infusion of Lidocaine on Postoperative Pulmonary Complications and Prognosis in Emergency Surgical Patients With Intra-abdominal Infection

Status Active, not recruiting

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.

Clinical Trial 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. ;
