Abstract
Thoracic surgery is associated with significant postoperative pain, which can hinder recovery and elevate morbidity risks. Traditionally, epidural anesthesia has been the cornerstone for pain management, but its drawbacks including technical challenges, side effects, and complications necessitate exploring alternative methods. This narrative review examined recent advances in perioperative analgesic strategies in thoracic surgery, focusing on regional anesthetic techniques like paravertebral blocks (PVBs), erector spinae plane blocks (ESPBs), intercostal blocks, and serratus anterior blocks. Each approach was evaluated for efficacy, safety, and impact on patient outcomes. PVB can provide effective unilateral analgesia with fewer systemic complications compared to epidurals. ESPB provides analgesia through a superficial, ultrasound-guided approach, minimizing risks and offering an alternative for various thoracic procedures. Intercostal blocks are effective but are limited by the need for multiple injections, increasing the complication risks. Serratus anterior blocks, targeting intercostal and thoracic nerves, show promise in managing lateral thoracic wall pain with a low complication rate. Advancements in surgical techniques including minimally invasive approaches further optimize pain control and recovery. A multimodal analgesic approach combining regional anesthesia and systemic therapies enhances outcomes by addressing somatic and visceral pain components. Despite the efficacy of epidural analgesia, alternative regional techniques offer comparable pain relief with fewer complications, suggesting their growing role in thoracic surgery. Collaborative efforts between surgical, anesthetic, and emergency teams are crucial for tailoring pain management strategies to individual patients, improving recovery and reducing long-term morbidity. Future research should continue exploring these methods to refine their application and broaden their accessibility.
