Clinical Scorecard: Efficacy of Intravenous Lidocaine for Alleviating Post-Surgical Pain Following Hand-Assisted Laparoscopic Colon Surgery: A Randomized, Placebo-Controlled Study

At a Glance

Key Highlights

• IV lidocaine infusion reduces post-operative pain levels after hand-assisted laparoscopic colon surgery
• Lidocaine administration facilitates earlier restoration of bowel function and shortens hospital stay
• Standardized anesthesia with lidocaine bolus and continuous infusion was well tolerated and compared to placebo

Guideline-Based Recommendations

Diagnosis

• Assess patients scheduled for hand-assisted laparoscopic colon surgery for eligibility including ASA score and absence of contraindications to lidocaine

Management

• Administer IV lidocaine bolus (1.5 mg/kg, max 100 mg) before anesthesia induction
• Continue IV lidocaine infusion at 2 mg/kg/h intraoperatively and 1 mg/kg/h postoperatively for 24 hours
• Maintain standardized general anesthesia with fentanyl, propofol, rocuronium, and sevoflurane

Monitoring & Follow-up

• Monitor intraoperative blood pressure and heart rate, maintaining within 20% of baseline
• Adjust anesthesia depth using bispectral index between 40 and 60
• Observe for lidocaine-related adverse effects and ensure continuous postoperative analgesia

Risks

• Exclude patients with severe hepatic, renal, cardiac, respiratory, endocrine diseases, or allergy to local anesthetics
• Avoid in patients with history of alcohol or drug addiction or preoperative analgesic use

Patient & Prescribing Data

Adults aged 18–75 years with colon cancer undergoing elective hand-assisted laparoscopic colon surgery

IV lidocaine reduces opioid requirements, improves pain control, accelerates bowel function recovery, and shortens hospital stay compared to placebo

Clinical Best Practices

• Use a double-blinded, placebo-controlled approach to evaluate analgesic efficacy
• Standardize anesthesia protocols to minimize confounding variables
• Ensure continuous postoperative lidocaine infusion for 24 hours to maximize analgesic benefits
• Employ experienced surgical teams for consistent operative technique
• Exclude patients with contraindications to lidocaine to enhance safety
