Abstract

Background: The presence of meconium in amniotic fluid is indicative of foetal distress. Bishop score helps guide the mode of delivery. However, in presence of meconium-stained liquor, the decision may be based on severity of foetal distress. The objective of the study was to see the association of Bishop score with mode of delivery in women with meconium-stained amniotic fluid.

Methods: Women admitted in labour room were classified as those with clear liquor or meconium stained. Bishop score was noted of all. Labour was monitored and decision of mode of delivery was made as per protocol. Data was analysed.

Results: 50 women, out of the 250 monitored had meconium-stained liquor (MSL). MSL had significant association with mode of delivery. There was association between bishop score and mode of delivery. There was a higher caesarean delivery rate with MSL. A <7 score had greater risk of cesarean delivery. Primigravida had poorer Bishop score and hence had a higher cesarean section rate.

Conclusions: Presence of meconium and bishop score effect mode of delivery. Close monitoring improves the neonatal outcome. Counselling regarding mode of delivery after estimating the Bishop score can be done.
