Information

Meconium is a thick, sticky, greenish-black substance. It is the medical term for the newborn infant's first stools. Meconium is made of amniotic fluid, mucus, lanugo (the fine hair that covers the baby's body), bile, and cells that have been shed from the skin and the intestinal tract. Infant stools typically change from meconium to seedy/mustardy yellow/green stools in 4 - 5 days.

During pregnancy, the baby floats in the amniotic fluid that fills the mother's uterus. This fluid protects the baby while he or she grows and develops. The baby swallows the amniotic fluid, which contains all the other constituents mentioned above. All of the contents other than the amniotic fluid itself are filtered out and remain behind in the intestine while the amniotic fluid is absorbed and re-released into the uterine space when the fetus urinates. This cycle maintains the amniotic fluid in a clear, healthy state during the nine months of pregnancy. This process of recycling the amniotic fluid occurs about every 3 hours.

In some cases, the baby passes stools (meconium) while still inside the uterus, and it is possible for the baby to breathe the meconium into the lungs. For more information on this condition, see meconium aspiration.

When would meconium be present?

Meconium is found in a baby's intestines during pregnancy. It is a thick green tar like substance. Usually the meconium is released after the baby's birth. However, sometimes a baby will have a bowel movement before birth and the meconium will then go into the amniotic fluid. This could be dangerous for the baby.

What is it called when there is fetal feces in the amniotic fluid?

"Meconium in the amniotic fluid". Meconium is a very dark green color. It can also be referred to as "meconium stain" when there is only a small amount in the fluid. Meconium is the name for the infants' first fecal material, which has some different characteristics than that of later stools that are the products of food digestion. Meconium in the amniotic fluid can sometimes (but not always) be an indication of fetal distress during delivery, or certain medical conditions in a baby. I know in Portuguese: mecônio.

Does meconium still come out of the butterfly after it is out of the chrysalis?

Not after the abdomen has shrunken and the wings have stiffened. Meconium is only secreted just after emerging when the abdomen is still ´fat´.


What meconium that come out of butterflies?

Butterflies do not produce meconium like mammals. Instead, what might be referred to as "butterfly meconium" is actually the excretion of waste from the caterpillar stage, which is expelled after metamorphosis. This waste is typically in the form of frass (caterpillar droppings) and is not related to meconium in the context of mammalian development. Once butterflies emerge from their chrysalises, they focus on feeding and reproduction rather than waste elimination.


Why does meconium staining occur predominantly in infants greater than 36 weeks of gestational?

Meconium staining occurs predominantly in infants greater than 36 weeks of gestation because the risk of meconium passage increases as the fetus matures and approaches term. At this stage, the fetal gut is fully developed, and the likelihood of stressors, such as uterine contractions or hypoxia, can lead to the release of meconium into the amniotic fluid. Additionally, the ability of the fetus to clear meconium from the intestines diminishes with gestational age, making it more likely to be expelled into the amniotic cavity.

Can baby die if swallows Meconium?

Yes, a baby can experience serious complications if they swallow meconium, particularly if it occurs during labor and delivery, a condition known as meconium aspiration syndrome. This happens when a newborn inhales a mixture of meconium and amniotic fluid into the lungs, which can lead to breathing difficulties and other health issues. Prompt medical intervention is crucial to manage the situation and reduce the risk of serious outcomes.
