Background: Limited research exists that investigates the language parents and health professionals use when faced with a high-risk likelihood of fetal demise or an instance of fetal loss. This review examines the language used when referring to the ‘fetus’ in these cases to better understand the meaning different groups might ascribe to the fetus and how their word choice may reflect their strategies for managing in these situations. Methods: An integrative review of primary, peer-reviewed research was conducted. A systematic search of seven databases was undertaken, articles critiqued and summarised using the Preferred Reporting Items for Systemic Reviews and Meta-Analysis (PRISMA). The comprehensive process of data analysis and synthesis followed a constant comparison approach. Results: The 23 included studies represented the voices of women, their partners, obstetricians, nurses, midwives and allied health professionals. Five major themes emerged with the main finding being that the term ‘Baby’ is the most widely recognised word used in instances of fetal loss and high risk of fetal demise. Conclusion: History, science and law all influence how the fetus is understood and discussed within society. This review contributes new insights into our understanding of the term ‘fetus’ emphasizing the need for further research into the way the fetus is addressed and dealt with in instances of fetal loss or high risk of fetal loss within Maternity care practices.
