OBJECTIVE: To compare different methods of intrapartum foetal heart rate monitoring in high risk pregnancies in detecting foetal heart rate abnormalities, need for operative delivery for foetal distress, and neonatal mortality and short term neonatal morbidity. DESIGN: A prospective randomised controlled trial. SETTING:Women in labour at a referral maternity hospital. PATIENTS: Women who were 37 weeks or more pregnant with singleton cephalic presentation and normal foetal heart rate prior to entry into the study. INTERVENTION: Women were randomly allocated using sealed opaque envelopes to either continuous electronic foetal heart rate monitoring or intermittent monitoring using hand held doppler foetal heart rate detector. OUTCOME MEASURES: These include abnormal foetal heart rate patterns, need for operative delivery for foetal distress, neonatal mortality, Apgar scores, admission to NNU, neonatal seizures, and hypoxic encephalopathy. RESULTS: Randomisation achieved good comparability between the two groups. Abnormal FHR patterns were more frequent in the electronic group (54 pc versus 32 pc). Caesarean section rate was not significantly different in the two groups (28 pc versus 24 pc) although slightly higher compared to overall for the unit (18pc). Foetal outcome was also comparable between the two groups. CONCLUSIONS: Asphyxia can be detected with a hand held doppler just as reliably as by the use of electronic monitors and their use should be further evaluated and promoted in obstetric units caring for high risk pregnancies in developing countries with scarce resources.
