The postoperative acute pain caused by surgery has been a major problem plaguing anesthesiologists, and even some acute pain progresses to chronic pain syndrome, terribly reducing the quality of life of patients. To this end, increasing attention has been paid to the management of perioperative analgesia. At present, with the increase of research on perioperative analgesia, the understanding and solution of this clinical problem have been further developed. Bibliometrics can estimate research hot-spots and trends of related fields in a certain period of time. However, a systematic bibliometric analysis has not been conducted to explore current research hotspots and future development trends, which is thus the purpose of this study.
