Simple fetal heartbeat monitoring still best to reduce unnecessary cesarean sections

Researchers from the United Kingdom and Spain reviewed 33 studies that included more than 118,000 women, mainly from high-income countries as well as India and Tanzania, to evaluate the effectiveness of different monitoring methods in improving outcomes for mothers and babies and reducing the number of cesarean deliveries.

They found that all methods had similar outcomes for babies, but only intermittent auscultation reduced the risk of cesarean deliveries without increased risk to babies' health. The researchers estimate that intermittent auscultation led to an average 30% reduction in emergency cesareans compared to other methods.

"Our analysis suggests that all additional methods introduced to improve the accuracy of electronic fetal heart monitoring have failed to reduce the risk of adverse neonatal or maternal outcomes beyond what intermittent auscultation achieved 50 years ago, and this may have contributed to the increased incidence of unnecessary emergency cesarean deliveries," write the authors.

The authors urge investment in developing novel techniques to monitor fetuses to make delivery safer for mothers and their babies.
