Intravenous Lidocaine on Chronic Pain in Patients Undergoing Hepatectomy
Postoperative Chronic Pain
About this trial
This is an interventional treatment trial for Postoperative Chronic Pain focused on measuring lidocaine
Eligibility Criteria
Inclusion Criteria:
Age: 18-80 years old American Society of Anesthesiologists(ASA) Ⅰ~III BMI≤30 Primary single hepatocellular carcinoma resection was proposed for patients undergoing laparotomy (median incision, right subcostal incision/inverted L-shaped incision)
Exclusion Criteria:
Primary liver cancer with malignant tumors of other organs (such as lung, kidney, intestine, etc.).
Primary hepatocellular carcinoma with portal vein or inferior vena cava and other large vascular thrombus.
Long-term opioid use, alcohol or drug abuse or any of the drugs (lidocaine, etc.) used in this study were contraindicated and allergic for patients.
Patients with severe hepatic and renal dysfunction (total bilirubin >1.46mg/dl, glomerular filtration rate <30ml/min /1.73㎡ or end-stage renal disease).
Severe heart disease (severe heart block (including sinoatrial, atrioventricular, and intraventricular block); Severe heart failure (ejection fraction <20%); Sinus bradycardia; Patients with Adams-Stokes syndrome, preexcitation syndrome, etc Patients with a history of uncontrolled seizures or acute porphyria. Long-term use of cimetidine and β-blockers (lidocaine metabolism is inhibited through the liver, resulting in increased blood concentration of the drug, which can lead to adverse cardiac and nervous system reactions).
Patients treated with drugs that are contraindicated with lidocaine (phenobarbital, thiopental, sodium nitroprusside, mannitol, amphotericin B, ampicillin, mesonotal, sulfadiazine sodium); Patients who are using enoxacin, lomefloxacin, norfloxacin, and prulifloxacin.
Patients with a history of gastrointestinal bleeding or perforation after nsaids;Patients with active gastrointestinal ulcers/bleeding or who have had recurrent ulcers/bleeding in the past.
Patients who had taken other experimental drugs or were participating or participating in other clinical trials within 3 months of enrollment.

Placebo Comparator
Lidocaine group
Conventional analgesia group
General anesthesia is induced in the lidocaine group with intravenous lidocaine 1.5mg/kg for ten minutes, followed by continuous injection of lidocaine 1.5mg/kg.h. At the end of the operation, the patient controlled intravenous analgesia with lidocaine is used, and the dose of lidocaine is 30mg/kg(no more than 2000mg at most).
The lidocaine is replaced by identical volumes and rates of 0.9% saline. At the end of the operation, the patient controlled intravenous analgesia without lidocaine is used.
