MEASUREMENT OF AMNIOTIC FLUID VOLUME- GRAY-SCALE VERSUS COLOUR DOPPLER ULTRASOUND
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 47
Abstract
BACKGROUND Amniotic fluid volume assessment is important during the pregnancy because of the association between abnormal levels of amniotic fluid volume and perinatal morbidity and mortality. Gray-scale sonography is a method usually used to assess the amniotic fluid volume. It is hypothesized that colour Doppler can decrease amniotic fluid volume measure. We aimed to compare the amniotic fluid volume obtained with gray-scale and colour Doppler sonography. MATERIALS AND METHODS In this descriptive-analytical study, 440 pregnant women were included, who were referred to the sonography center of Shahid Beheshti Hospital in Babol, north of Iran, for foetal health assessment during 2010-2012. The exclusion criteria included the twin pregnancy and birth defects. Amniotic fluid volume was primarily measured by the gray-scale sonography using the single deepest pocket measurement method, and then the same pocket was measured by colour Doppler if the foetus did not move. Oligohydramnios was defined as an amniotic fluid volume less than 2 cm. RESULTS The mean maternal age was 26.12±4.83 years (16-42 years old). The mean gestational age of the subjects was 32.28±5.71 weeks, ranging from 13 to 40 weeks. The mean amniotic fluid volume with gray-scale sonography was significantly more than that with colour Doppler sonography (4.47±1.06 cm versus 4.26±1.32 cm, p<0.0001). Two patients (0.5%) with oligohydramnios were detected by gray-scale, while this rate was 28 (6.4%) based on colour Doppler (p<0.0001). CONCLUSION Our results indicated that colour Doppler ultrasound can increase the diagnosis of oligohydramnios. We propose to use the colour Doppler for measurement of amniotic fluid volume in pregnant women to improve accuracy of amniotic fluid volume evaluation.
