The diagnosis of foetal distress: a challenge to midwives.

The diagnosis of foetal distress is complex: it is influenced by a number of factors which range from the physical examination of the mother and foetus to the psychological and social world in which the mother, the midwife and other health care professionals work. The consequences of an incorrect diagnosis of normality or foetal distress are potentially serious for both mother and baby. Recent changes in the practice and delivery of midwifery care have placed more responsibility on midwives. It is therefore imperative that midwives become more aware of the complexity of the diagnosis as well as of some of the factors which can improve the quality of their diagnosis. This paper reviews the literature associated with the diagnosis of foetal distress, physiological and pathological changes during pregnancy and labour, and the usefulness and limitation of the tools readily available to midwives for the diagnosis. It also examines the limits of the relationship that exists between intra-uterine and neonatal markers. The purpose of this paper is to provide background information that would support midwives in the diagnosis of foetal distress in the hope that the false positive diagnoses can be reduced for the benefit of mothers and babies. Ultimately an improvement in outcome should be reflected in the more efficient and effective use of resources available to maternity services.
