Anaemia in infants is a major public health concern particularly in low and middle-income countries. Delayed cord clamping (DCC) has been advocated as a strategy to decrease iron deficiency anaemia in infants because of the benefits that come with placental transfusion. Despite the documented benefits of delayed cord clamping in preventing anaemia the current practices of delayed cord clamping by midwives and obstetricians across countries and in different contexts is unclear. This narrative review assesses the literature on delayed cord clamping practices published from 2013 to February 2022, in order to examine current practice in birth units globally, and with a focus in low and middle-income countries (LMICs).
A search of four bibliographic databases Medline, Scopus (Elsevier), ProQuest, CINAHL and two network and search engines, Wiley and Google Scholar, was undertaken from 2013 to February 2022 using key terms related to delayed cord clamping and immediate cord clamping. A snowball method as well as backward and forward reference checking was also undertaken.
The search strategy identified 10 studies on umbilical cord clamping practices by midwives and obstetricians. Only two studies were conducted in low and middle-income countries.
Despite the potential benefits of DCC in reducing anaemia, particularly in low and middle-income countries where the burden of anaemia is a public health concern, there is a paucity of literature on current DCC practices by obstetricians and midwives. Research to establish current DCC practices in these countries is needed to address this gap in the literature.
婴儿贫血是一个重大的公共卫生问题，尤其是在中低收入国家。由于胎盘输血带来的益处，延迟脐带夹闭（DCC）被提倡作为减少婴儿缺铁性贫血的一种策略。尽管有文件证明延迟脐带夹闭在预防贫血方面的益处，但各国和不同背景下的助产士和产科医生对延迟脐带夹闭的现行做法尚不清楚。本叙述性综述评估了 2013 年至 2022 年 2 月发表的关于延迟脐带夹闭实践的文献，目的是检查全球分娩单位的当前实践，并重点关注中低收入国家（LMICs）。
从 2013 年至 2022 年 2 月，使用与延迟脐带夹闭和立即脐带夹闭相关的关键词，对 Medline、Scopus（爱思唯尔）、ProQuest、CINAHL 这四个文献数据库以及 Wiley 和 Google Scholar 这两个网络和搜索引擎进行了检索。还进行了滚雪球法以及回溯和前向参考文献检查。
搜索策略确定了 10 项关于助产士和产科医生脐带夹闭做法的研究。只有两项研究在中低收入国家进行。
尽管 DCC 有减少贫血的潜在益处，特别是在贫血是公共卫生问题的中低收入国家，但关于产科医生和助产士目前 DCC 做法的文献很少。需要在这些国家开展研究，以了解目前 DCC 的做法，从而填补文献中的空白。
