Intermittent auscultation of fetal heart rate during labour – a widely accepted technique for low risk pregnancies: But are the current national guidelines robust and practical?

Abstract

Intermittent auscultation of fetal heart rate is an accepted practice in low risk labours in many countries. National guidelines on intrapartum fetal monitoring were critically reviewed regarding timing and frequency of intermittent auscultation. Hypothetical but plausible examples are presented to illustrate that it may be possible to miss significant fetal distress with strict adherence to current guidelines. Opinion is forwarded that intermittent auscultation should be performed for 60 seconds before and after three contractions over about 10 min every half an hour in the first stage of labour. Reasons are put forward to show how this could be more practical and patient friendly and at the same time could improve detection of fetal distress. The current recommendation of intermittent auscultation every 15 min in the first stage is associated with poor compliance and leads to unnecessary burden, stress and medicolegal liability for birth attendants. Modification of current national guidelines would be desirable.
