Chronic postsurgical pain has become one of the most common complications of surgery. The quality of life will be impacted once the postsurgical patients are combined with persistent pain. What's more, the postsurgical pain may increase other adverse outcomes. It's important to find a better way to keep the postsurgical patients away from postoperative pain. Esketamine and pregabalin have become potentially effective drugs on CPSP.
