Foetal outcome in patients with meconium stained liquor

To determine the foetal outcome and mode of delivery in patients with meconium stained liquor during labour.

The observational study was carried out at the Obstetrics and Gynaecology Unit-II of Liaquat University of Medical Health Sciences from June to November 2007. The patients with gestational age more than 37 weeks who presented with meconium stained liquor and cephalic presentation were included and the foetal outcome and mode of delivery was assessed in all such subjects. The data was collected on pre-designed proforma and analysed using SPSS version 10. Chi square test was applied with 95% confidence interval and p-value < or = 0.05 was considered significant.

A total of 75 patients with meconium stained liquor were identified during the study period. The patients with reactive cardiotocography (CTG) were 50 (66.7%) and with non-reactive CTG, 25 (33.36%). Of the total, 45 (60%) patients were delivered through normal vaginal delivery, while 30 (40%) were delivered by caesarean section. The rate of instrumental delivery was also increased which was 12 (26.7%). Among the neonates exposed to meconium stained liquor, 62 (82.7%) babies were delivered with apgar score > 7. Only 13 (17.3%) babies were delivered with apgar score < 7 in one minute.

Meconium stained amniotic fluid is a common occurrence during labour and is associated with increased caesarean section rate and foetal morbidity and mortality.
