, Fetal Monitoring
• Continuous intrapartum fetal monitoring since the
1970’s
• Low risk mothers – Continuous EFM confers no
benefit to the fetus (McDonald et al 1985) and increases
obstetric intervention (NICE 2004, Mongeli at al 1997, Supplee & Vezeau 1996,
Thacker et al 1995)

• Most common reason for Caesarean (CS) is
presumed fetal compromise
• Indirect link between CS rates and Maternal
Mortality (Hall 2001)
