What this trial studies

The CPSP-Cardiac is a large, multi-center observational study aimed at understanding the incidence of chronic post-surgical pain in patients three months after cardiac surgery. It focuses on patients undergoing first-time cardiac surgeries, such as coronary artery bypass grafting and valvular repairs, and examines various factors that may influence pain outcomes. The study utilizes Enhanced Recovery After Surgery (ERAS®) protocols to improve pain management and patient recovery. By analyzing the effectiveness of multimodal analgesia strategies, including ultrasound-guided regional anesthesia, the study seeks to provide insights into preventing chronic pain and enhancing quality of life for cardiac surgery patients.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies that reduce the incidence of chronic pain in cardiac surgery patients.

How similar studies have gone: Other studies have shown promise in using multimodal analgesia and regional anesthesia techniques to improve acute pain management, but the long-term effects on chronic pain in this specific population remain less explored.
