Meconium is the primeval stool of a mammalian babe resulting from defecation. Different later feces, meconium is equanimous of materials ingested during the time the babe spends in the uterus: intestinal epithelial cells, lanugo, mucus, amniotic fluid, bile and water. Meconium, unlike later feces, is gummy and sticky like tar, its colour ordinarily being a very dark olive green; it is almost odorless.[1] When diluted in amniotic fluid, it may appear in various shades of green, brown, or yellow. It should be completely passed past the stop of the first few days later on birth, with the stools progressing toward yellow (digested milk).

Clinical significance [edit]

Meconium in amniotic fluid [edit]

Meconium is normally retained in the infant'south bowel until after birth, just sometimes it is expelled into the amniotic fluid (also called "amniotic liquor") prior to nascence or during labor and commitment. The stained amniotic fluid (called "meconium liquor" or "meconium-stained liquor") is recognized by medical staff as a possible sign of fetal distress. Some mail-dates pregnancies (when they are more than 40 weeks meaning) may likewise have meconium-stained liquor without fetal distress. Medical staff may aspirate the meconium from the nose and oral fissure of a newborn immediately afterward delivery in the issue the infant shows signs of respiratory distress to decrease the adventure of meconium aspiration syndrome, which can occur in meconium-stained amniotic fluid.

Nearly of the time that the amniotic fluid is stained with meconium, it volition be homogeneously distributed throughout the fluid, making it chocolate-brown. This indicates that the fetus passed the meconium some time ago such that sufficient mixing occurred as to found the homogeneous mixture. Terminal meconium occurs when the fetus passes the meconium a short enough time before nativity/cesarean section that the amniotic fluid remains clear, simply individual clumps of meconium are in the fluid.

Failure to laissez passer meconium [edit]

The failure to laissez passer meconium is a symptom of several diseases including Hirschsprung's illness and cystic fibrosis.

The meconium sometimes becomes thickened and congested in the intestines, a condition known as meconium ileus. Meconium ileus is oft the first sign of cystic fibrosis.[two] In cystic fibrosis, the meconium can form a bituminous blackness-greenish mechanical obstruction in a segment of the ileum. Beyond this, in that location may exist a few separate grey-white globular pellets. Below this level, the bowel is a narrow and empty micro-colon. In a higher place the level of the obstruction, there are several loops of hypertrophied bowel distended with fluid. No meconium is passed, and abdominal distension and vomiting appear soon subsequently nascency. Virtually 20% of cases of cystic fibrosis present with meconium ileus, while approximately 20% of one series of cases of meconium ileus did non have cystic fibrosis.[3] The presence of meconium ileus is not related to the severity of the cystic fibrosis.[4] The obstruction can be relieved in a number of different ways.[five]

Meconium ileus should exist distinguished from meconium plug syndrome, in which a tenacious mass of mucus prevents the meconium from passing and there is no gamble of abdominal perforation. Meconium ileus has a meaning take a chance of intestinal perforation. In a barium enema, meconium plug syndrome shows a normal or dilated colon as compared to micro-colon in meconium ileus.

Testing meconium for drugs [edit]

Meconium can exist tested for various drugs, to check for in utero exposure. Using meconium, a Canadian inquiry group showed that by measuring a by-product of alcohol, fatty acid ethyl esters (FAEE) they could objectively find excessive maternal drinking of alcohol during pregnancy.[6] In the US, the results of meconium testing may be used by child protective services and other police force enforcement agencies to determine the eligibility of the parents to proceed the newborn.[7] Meconium tin can as well exist analyzed to detect the tobacco employ of mothers during their pregnancy, which is commonly under-reported.[8]

Sterility [edit]

The issue of whether meconium is sterile remains debated and is an expanse of ongoing research. Although some researchers have reported evidence of bacteria in meconium,[nine] this has not been consistently confirmed. Other researchers have raised questions most whether these findings may exist due to contamination later on sample collection and that meconium is, in fact, sterile until after birth.[10] Further researchers have hypothesized that in that location may be bacteria in the womb, but these are a normal part of pregnancy and could accept an important role in shaping the developing immune system and are not harmful to the baby.[eleven]

Etymology [edit]

The Latin term meconium derives from the Greek μηκώνιον , mēkōnion, a diminutive of μήκων , mēkōn, i.e. poppy, in reference either to its tar-similar appearance that may resemble some raw opium preparations or to Aristotle's conventionalities that it induces sleep in the fetus.[12] [13] [fourteen]

Other uses [edit]

  • In biology, meconium describes the metabolic waste matter production from the pupal phase of an insect that is expelled through the anal opening of the adult upon eclosion from the pupa. Other insects, such as beetles and some Hymenoptera (Aculeata) expel the meconium at the finish of the larval phase, before becoming a pupa.
