Postdates pregnancy has many complications during and after delivery. Meconium stained amniotic fluid is a common occurrence during labor and is associated with increased caesarean section rate and fetal morbidity and mortality. Meconium stained liquor is the most occurring problem in postdate pregnancy, usually encountered by obstetricians. But controversial results are present in literature. So we conducted this study to find the extent of problem in local population. The objective of this study is to assess the frequency of meconium stained liquor in females presenting with postdates pregnancy. Methods: A cross sectional study was conducted at Shifa International Hospital Islamabad, from December 2018 to June 2019. The sample size of 225 cases was included and after taking approval from ethical review board and department, the patients were included through convenient sampling. Data was entered and analyzed through SPSS version 26. The quantitative data like age, BMI and gestational age were presented as mean and standard deviation. Qualitative variables like meconium-stained liquor were presented as frequency and percentage. Parity was also presented as frequency. Data was stratified for age, gestational age, parity and BMI. Post-stratification, meconium-stained liquor was compared in stratified groups by using chi-square test considering P-value≤0.05 as significant. Results: The mean age of females was 29.43±6.10years. The mean gestational age of females at the time of delivery was 40.40±0.49 weeks. The mean BMI of females was 25.52±5.13kg/m2 . Meconium stained liquor was observed in 52 (23.11%) cases. Conclusion: This study indicate that while meconium-stained liquor is a frequent issue in postdate deliveries, its prevalence does not show a statistically significant correlation with any factors. There is the need for monitoring of postdate pregnancies, regardless of maternal characteristics, as meconium-stained liquor remains a prevalent concern with potential complications for maternal and neonatal outcomes.
