Clinical Abdominal Palpation for Predicting Oligohydramnios in Suspected Prolonged Pregnancy

Objective. In view of the scarcity of ultrasound in low-resource settings; to evaluate abdominal palpation for prediction of oligohydramnios in suspected prolonged pregnancy; using the ultrasound-obtained amniotic fluid index (AFI) as a gold standard; taking into account maternal and fetal factors that may affect amniotic fluid volume. Methods. A cross-sectional analytical study at Chris Hani Baragwanath Academic Hospital; Johannesburg; South Africa; on women referred from midwife-run clinics with suspected gestational age ?41 weeks. Eligible women had their AFI measured; then had abdominal palpation by the researcher; who was blinded to exact gestational age and AFI findings. Palpation focused on ballottability of fetal parts; ease of feeling fetal parts; and impression of fetal compaction. Gestational age was then recalculated using information from earlier ultrasound scans and menstrual dates. Univariable and multivariable logistic regression was performed with oligohydramnios (AFI 5 cm) as the dependent variable.Results. Of 100 women; 45 had a recalculated gestational age ?41 weeks. Twenty-three had oligohydramnios. Gestational age was a significant independent predictor for oligohydramnios (odds ratio (OR) 1.78; 95 confidence interval (CI) 1.08 - 2.94). The only component of palpation significantly associated with oligohydramnios; after adjustment for gestational age; was non-ballottability of the presenting part (adjusted OR 4.02; 95 CI 1.05 - 15.4). Non-ballottability had a sensitivity and specificity for oligohydramnios of 87 and 40; respectively; with a negative predictive value of 91.Conclusion. When ultrasound is not available; ballottability of the presenting part may have value for excluding oligohydramnios and assisting clinical decisions in suspected prolonged pregnancy
