Opioid-Free Anesthesia for Lung Cancer Resection: A Case-Control Study

Area of Science:

• Anesthesiology
• Thoracic Surgery
• Oncology

Background:

• Opioid-based anesthesia is standard for lung cancer resection but carries risks.
• Opioid-free anesthesia (OFA) presents an alternative approach.
• Assessing OFA feasibility and effectiveness in lung cancer surgery is crucial.

Purpose of the Study:

• To evaluate the feasibility and effectiveness of an opioid-free anesthesia (OFA) technique.
• To compare OFA with standard opioid-based anesthesia in lung cancer resection surgery.
• To analyze postoperative pain, opioid consumption, and recovery metrics.

Main Methods:

• Retrospective, propensity-matched, case-control study.
• 83 patients undergoing OFA matched with 83 patients receiving standard anesthesia for lung cancer resection.
• Comparison of postoperative pain scores, morphine consumption, and length of stay.

Main Results:

• No significant difference in pain scores at 0 or 24 hours post-surgery.
• Opioid-free anesthesia group showed significantly lower pain scores at 1 hour post-surgery.
• Similar 24-hour morphine consumption and recovery room stay; significantly shorter hospital stay in the OFA group.

Conclusions:

• Opioid-free anesthesia is a feasible and safe alternative for lung cancer resection.
• OFA results in comparable postoperative pain and opioid use to standard techniques.
• OFA may lead to reduced hospital length of stay, enhancing recovery.
