Pain management strategies following thoracic surgery: best practices and innovations.

Pain after thoracic surgery can be among the most severe, complex, and difficult to manage of any procedure. Acute pain has somatic, visceral, and neuropathic components, and its severity is the strongest modifiable predictor of chronic post-surgical pain. Inadequate analgesia drives complications, delays recovery, and may progress to chronic post-surgical pain. This review synthesizes the pathophysiology of acute and chronic pain after thoracic surgery, examines the updated guideline recommendations for regional anesthesia, describes methods that can be used as part of a comprehensive pain control protocol after thoracic surgery, and points to promising future developments. Surgical approach is a powerful determinant of pain, and minimally invasive access reduces acute pain relative to open thoracotomy. Multimodal analgesia combining systemic agents with procedure-specific regional anesthesia remains the foundation of perioperative management, but guidelines strongly emphasize the use of regional anesthesia as an adjunct for pain control. Recent studies suggest that moving towards surgeon-administered blocks and implementation of developing technologies may improve the efficacy and decrease the resources needed for analgesia after thoracic surgery. Future priorities include trials with standardized outcomes, cost-effectiveness analyses, validation of newer therapies, and long-term follow-up. Overall, protocols for pain management after thoracic surgery should focus on an evidence-based, patient-centered framework for analgesia selection to optimize recovery and reduce the rate of complications.
