Research hotspots and trends on post-cesarean section analgesia: A scientometric analysis from 2001 to 2021.

Abstract

This study aims to demonstrate current research priorities and predict future trends of post-cesarean section analgesia by scientometric analysis. We collected nearly 20 years (2002-2021) of publications related to post-cesarean section analgesia in the web of science database. Citespace was applied to evaluate the knowledge mapping. There are 2735 manuscripts about the post-cesarean section in total. The country, institution, and author posted the most separately are the USA, Univ Calif Irvine, and BRENDAN CARVALHO. INTERNATIONAL JOURNAL OF OBSTETRIC ANESTHESIA (21) publishes the most articles of this type, and ANESTHESIOLOGY has the greatest impact (1496 co-citations). In addition, the most key cited reference is McDonnell, J.G (43). Post-cesarean section analgesia research, including spinal anesthesia, postoperative pain, and epidural analgesia, has been a research hotspot in recent years. Through scientometric analysis of the past 20 years, we know the TAP blocks and drug selection in patient-controlled analgesia are the focus of future research. The USA, China, and Turkey have become the main research forces in this field, with high publication rates and centrality. This is important for accurately and quickly locating trends in this field.
