Mechanisms of Remifentanil-Induced Postoperative Hyperalgesia: A Comprehensive Review.

Remifentanil, a widely used ultra-short-acting μ-opioid receptor agonist in clinical anesthesia, is strongly associated with postoperative hyperalgesia (remifentanil-induced hyperalgesia, RIH), posing significant challenges to postoperative pain management. RIH is characterized by an abnormally heightened pain perception following opioid withdrawal, and its underlying mechanisms are complex and multifactorial. Current research highlights the roles of central sensitization, peripheral sensitization, and multiple interacting molecular pathways.
