Labor analgesia is part of the most important tasks an anesthesiologist needs to deal with. With the "two-child policy" in China, the number of parturients has increased significantly, labor analgesia more should be valued. There has been a tremendous change on labor analgesia research in China and around the world; however, broader trends in the prevalence and scope of labor analgesia research remain underexplored. The current study quantitatively analyzes trends in labor analgesia research publications in the past 30 years.
