DISCUSSION

It is reasonable to assume that an umbilical cord stained green is due to the Amniotic fluid can be stained green by bile pigments if the fetus baby having passed meconium in utero. We describe a newborn baby in has hemolytic disease, passes meconium, or vomits bile.2 In 1972, whom there was a delay in diagnosing an imperforate because the the first reported case of vomiting in utero was a neonate with an baby’s umbilical cord was stained green with bile and it was assumed that atretic jejunum.2 The obstetrician had diagnosed hydramnios with the baby had passed meconium in utero. ‘‘meconium-stained liquor.’’ After birth, a small catheter inserted Journal of Perinatology 2001; 21:467 – 468. into the dislodged some sticky white meconium with no lanugo hair. Another earlier report, in 1973, described a mother as having ‘‘golden liquor amnii’’ when the fore waters were ruptured.3 She delivered a live 36-week-old baby who had an CASE REPORT open 6-cm-diameter enterocoele containing stomach, small A term male neonate with a birthweight of 4.22 kg was born to a intestine, and half of the large bowel.
