External cephalic version (ECV) is a recommended procedure to reposition the fetus from a non-cephalic to a cephalic presentation, aiming to reduce the risks associated with breech presentation and increase the likelihood of a vaginal delivery. We aimed to determine the impact of neuraxial analgesia on the success rate and safety of ECV by conducting a systematic review and network meta-analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>A comprehensive search will be conducted in electronic databases such as Cochrane Central Register of Controlled Trials (The Cochrane Library), PubMed, Web of Science and Embase. Studies investigating the effects of neuraxial analgesia, including spinal and epidural analgesia, on ECV success rates and patient safety will be included. The primary outcome is the success rate of ECV, while secondary outcomes include adverse events, complications and maternal and fetal well-being.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>Ethical approval is not required as this review will analyse existing literature without patient involvement. The findings, which aim to assess the effects of neuraxial analgesia in ECV procedures, are expected to inform clinical practice and improve patient care. The results will be disseminated through publication in a peer-reviewed journal and presentation at relevant conferences.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>PROSPERO registration number<\/jats:title>\n                    <jats:p>CRD42023047525.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/bmjopen-2024-087603","type":"journal-article","created":{"date-parts":[[2025,8,25]],"date-time":"2025-08-25T01:45:20Z","timestamp":1756086320000},"page":"e087603","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Comparing spinal anaesthesia and epidural anaesthesia in cephalic external version: a protocol for systematic review and network meta-analysis"],"prefix":"10.1136","volume":"15","author":[{"given":"Cheng","family":"Mo","sequence":"first","affiliation":[{"name":"Anesthesiology, Guangxi Zhuang Autonomous Region People\u2019s Hospital, Nanning, Guangxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6758-6590","authenticated-orcid":false,"given":"Guangyu","family":"Liu","sequence":"additional","affiliation":[{"name":"Anesthesiology, Chinese Academy of Medical Sciences & Peking Union Medical College Fuwai Hospital, Xicheng, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"He","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Peking University First Hospital, Beijing, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,8,24]]},"reference":[{"key":"2025123106471753000_15.8.e087603.1","doi-asserted-by":"crossref","first-page":"210","DOI":"10.1016\/j.ejogrb.2018.10.036","article-title":"External cephalic version after previous cesarean section: A cohort study of 100 consecutive attempts","volume":"231","author":"Impey","year":"2018","journal-title":"Eur J Obstet Gynecol Reprod Biol"},{"key":"2025123106471753000_15.8.e087603.2","doi-asserted-by":"crossref","first-page":"269","DOI":"10.1016\/0002-9378(76)90609-8","article-title":"Variation of fetal presentation with gestational age","volume":"125","author":"Scheer","year":"1976","journal-title":"Am J Obstet Gynecol"},{"key":"2025123106471753000_15.8.e087603.3","doi-asserted-by":"crossref","DOI":"10.1371\/journal.pone.0225546","article-title":"The influence of the fetal leg position on the outcome in vaginally intended deliveries out of breech presentation at term -
