Abstract

Purpose

The presence of echogenic amniotic fluid at term gestation on sonography is uncommon. The aim of our study was to investigate the incidence of echogenic amniotic fluid at term pregnancy, and to determine how often echogenic amniotic fluid was associated with meconium.

Methods

All singleton pregnant women at term who were admitted to our labor unit and who delivered within 24 h of the ultrasound scan were included in the study. For each woman, gestational age, maternal age, gravidity, parity, the character of the amniotic fluid on ultrasound at admission (clear or echogenic), birth weight, and the character of the amniotic fluid on artificial or spontaneous rupture of membranes or on cesarean section (clear/with vernix/meconium-stained) were recorded.

Results

When amniotic fluid was assessed on ultrasound, among 278 patients, 9 (3.2%) patients’ amniotic fluid was echogenic. When the amniotic fluid was assessed at delivery, the rates of meconium-stained amniotic fluid in women with and without echogenic amniotic fluid were 44.44% (4/9) and 9.3% (25/269), respectively; the difference was statistically significant (p = 0.035). We found a sensitivity and specificity of 13.79 and 97.99%, and a positive and negative predictive value of 44.44 and 90.7%, respectively, for echogenic amniotic fluid seen on ultrasound in identifying meconium-stained amniotic fluid.

Conclusions

The incidence of echogenic amniotic fluid at term gestation was found as 3.2 and 44.4% of cases of echogenic amniotic fluid was associated with meconium.
