Document Type: Original Article



Introduction: meconium is the thick, Green - Black, with a bad odor material,  that founded around the third month of pregnancy in the intestines of fetus. 8 to 15 percent of infants has the evidence of meconium stained fluid at birth. In this study the factors affecting maternal and neonatal meconium-stained amniotic fluid be examined.
Methods: This study was done in the Vali-e- asr hospital in Birjand in 2011-2012. During this period, 48 delivery with meconium-stained amniotic fluid with 48 cases with clear amniotic fluid were compared. spss software and the t-test, Mann-Whitney and chi-square were used for data evaluation.
Results: The results showed that gestational age in meconium-stained amniotic fluid group was higher than the control group. If the distance of prior pregnancy to the current pregnancy was less, likelihood of meconium-stained amniotic fluid was higher, so the average distance in meconial group was 1.8 and in the control group was 2.8 years. Number of nulliparous women in the meconial group was more than control group.  This was showed with the most number of history of abortions in the control group. Rate of cesarean delivery was higher in meconium- stained amniotic fluid group than the control group, which was mainly due to the prevention of Complications. Sex of infants in meconium- stained amniotic fluid group was  more boy and in the control group was more girl.
Conclusion: The results of this study showed that in gestational age above, the low distance of the previous pregnancy , nulliparous women and male sex of fetus, is more likely to have meconium-stained amniotic fluid .
