Summary

This study aimes to evaluate whether perioperative intravenous lidocaine infusion effectively relieves postoperative pain, enhances recovery, and reduces chronic stump and phantom limb pain after amputation, thereby informing future multicenter trials and clinical guideline development.

Conditions

  • Amputation

Interventions

DRUG

Lidocaine Hydrochloride, Injectable

During anesthesia induction, intravenous lidocaine is administered at a dose of 1.5 mg/kg (based on ideal body weight) over 10 minutes. This is followed by a continuous infusion at 1.5 mg/kg/h until the end of surgery. Postoperative pain management involves the use of a patient-controlled intravenous analgesia (PCIA) device, which contains lidocaine 50 mg/kg (calculated based on ideal body weight, not exceeding 3500 mg), sufentanil 3 μg/kg (calculated based on ideal body weight for obese patients), and granisetron 12 mg, diluted to a total volume of 200 mL with 0.9% normal saline.

DRUG

0.9% normal saline

In the placebo group, the same volume of normal saline is administered during anesthesia. The postoperative PCIA device contains sufentanil 3 μg/kg (calculated based on ideal body weight for obese patients) and granisetron 12 mg, diluted to a total volume of 200 mL with 0.9% normal saline.
