Introduction: Meconium stained amniotic fluid has been considered a sign of fetal distress in presentation other than breech and associated with poor fetal outcome but others considered meconium passage by fetus is physiological phenomena and produce environmental hazards to fetus before birth. Methods: 200 women in labour with meconium stained amniotic fluid considering the inclusion and exclusion criteria at Teaching & General Hospital. Effect of thin and thick meconium on fetus was studied. Fetal monitoring, mode of delivery, Apgar score, birth weight, resuscitation of baby noted.All babies followed­up up to 1st week of neonatal life. result: Major complications were birth asphyxia, meconium aspiration syndrome, early neonatal death seen in 5.5% (11 cases), morbidity in 20.5%, 4.5% in thin and 16% in thick MSAF. Causes of death were meconium aspiration syndrome in 7 cases, sepsis in 2 cases, pneumonia in 1 case and birth asphyxia in 1 case. Conclusion: From our study we conclude that MSAF adversely affect fetal outcome mostly by thick meconium.
