n.
A dark green fecal material that accumulates in the fetal intestines and is discharged at or near the time of birth.

meconium

[mikō′nē·əm]
Etymology: Gk, mekon, poppy
a material that collects in the intestines of a fetus and forms the first stools of a newborn. It is thick and sticky, usually greenish to black, and composed of secretions of the intestinal glands, some amniotic fluid, and intrauterine debris, such as bile pigments, fatty acids, epithelial cells, mucus, lanugo, and blood. With ingestion of breast milk or formula and proper functioning of the GI tract, the color, consistency, and frequency of the stools change by the third or fourth day after the initiation of feedings. The presence of meconium in the amniotic fluid during labor may indicate fetal distress and may lead to a lack of oxygen and developmental delays.

meconium

A dark green viscid glue-like material found in the intestine of all neonates; it is the first stool passed by the newborns and is passed in the first 24-48 hrs of life; prenatal passage of meconium may indicate fetal distress

meconium

The thick, greenish-black, sticky stools passed by a baby during the first day or two of life, or before birth if the fetus is deprived of an adequate oxygen supply (fetal distress). Meconium consists of cells from the lining of the fetal bowel, bowel mucus and bile from the liver. Once feeding is established meconium is replaced by normal stools.

meconium

the gut contents of a mammalian foetus, formed of swallowed amniotic fluid and the secretion of glands into the gut.

Meconium

The first waste products to be discharged from the body in a newborn infant, usually greenish in color and consisting of mucus, bile and so forth.

meconium

yellow-orange mucilaginous material in the intestine of the full-term fetus; it constitutes the first stools passed by the newborn.

meconium aspiration
aspiration of fragments of meconium into the pulmonary airways occurs in the fetus in the terminal stages of many infections.
meconium ileus
intestinal obstruction in the newborn due to the blocking of the bowels with thick meconium. This is an important disease of newborn colt foals. The syndrome is usually one of subacute abdominal pain, restlessness and straining, and a positive finding on rectal examination. Occasional cases show severe pain and tympany of the large intestine. Called also meconium retention.

To find out the rate of Meconium aspiration syndrome (MAS) in babies born with Meconium-stained amniotic fluid (MSAF) in GGH, Guntur.
The study results show that the rate of caesarian section and meconium staining of amniotic fluid is higher in term pregnancies with isolated oligohydramnios.
On the basis of maternal self-report, 108 meconium samples were selected for this meconium alcohol marker investigation in the following categories: (a) no alcohol consumption at any time during pregnancy (n = 33); (b) mean third-trimester (>24 weeks) DPDD >10 (n = 14); (c) mean third-trimester DPDD 3-10 (n = 32); (d) mean third-trimester DPDD 0-<3 (n = 10); or (e) any drinking during the first or second trimesters with no drinking reported during the third trimester (n = 19).
Combined oesophageal atresia with upper pouch fistula and meconium peritonitis.
Fetal Distress: Fetal distress was labeled in only those newborns that had history provided by their Obstetricians of decrease fetal movement, meconium stained liquor, fetal tachycardia or bradycardia during or after a contraction, decreased variability in the fetal heart rate and late decelerations.
Meconium peritonitis occurs when a bowel wall rupture occurring during late fetal life or early postnatal life allows meconium to enter the peritoneal cavity.
Conclusion: Meconium stained amniotic fluid is a common occurrence during labour and is associated with increased caesarean section rate and foetal morbidity and mortality.
The main presenting complaints were difficulty in passing meconium, abdominal distension, constipation and vomiting during the course of diseases.
Arranged in sections on mares, stallions, and fetal and neonatal, the topics include artificial insemination, contraception in the mare, high-risk pregnancy, postpartum care of the mare and foal, twin pregnancy, castration, hemospermia, penile lacerations, angular limb deformities, determining the gender of a fetus, meconium aspiration, and bacterial and viral pneumonia.
Meconium passed by a baby during the first few days after birth can be used to determine how much the mother smoked or if she was exposed to tobacco smoke during pregnancy, according to US researchers who measured tobacco smoke metabolites in meconium samples from 337 babies.
