Efficacy of IV Lidocaine for Post-Surgical Pain in Hand-Assisted Laparoscopic Colon Surgery
Overview
This randomized, placebo-controlled study evaluated intravenous lidocaine's effectiveness in reducing post-operative pain, analgesic requirements, duration of ileus, and hospital stay in patients undergoing hand-assisted laparoscopic colon surgery. Results demonstrated that IV lidocaine significantly improved pain control and facilitated faster recovery compared to placebo.
Background
Hand-assisted laparoscopic surgery (HALS) for colon malignancies offers advantages such as accelerated bowel function recovery and reduced hospital stay. Effective post-operative pain management is crucial for enhancing surgical outcomes and patient comfort. Intravenous lidocaine has emerged as a promising analgesic due to its analgesic, antihyperalgesic, and anti-inflammatory properties, but its role in HALS requires further evaluation.

Key Findings
IV lidocaine administered as a bolus and continuous infusion during and after surgery significantly decreased post-operative pain levels.
Lidocaine infusion was associated with a shorter duration of post-operative ileus, facilitating earlier bowel function recovery.
Hospital stay was reduced in the lidocaine group, indicating faster overall recovery.
The study protocol ensured standardized anesthesia and surgical techniques to isolate the effect of lidocaine.
Clinical Implications
Intravenous lidocaine infusion can be considered an effective adjunct for post-operative pain management in patients undergoing hand-assisted laparoscopic colon surgery. Its use may reduce opioid consumption, promote earlier return of bowel function, and shorten hospitalization, thereby improving patient outcomes and resource utilization.
Conclusion
IV lidocaine is a safe and efficacious option for enhancing post-operative recovery after hand-assisted laparoscopic colon surgery, offering significant benefits in pain control and recovery metrics compared to placebo.
