• lungs
  • MAS can affect the baby's breathing in a number of ways, including chemical irritation to the lung tissue, airway obstruction by a meconium plug, infection, and the inactivation of surfactant by the meconium (surfactant is a natural substance that helps the lungs expand properly). (kidshealth.org)
  • Meconium can be inhaled into the lungs if the baby gasps while still in the womb or during the initial gasping breaths after delivery. (kidshealth.org)
  • If meconium gets into the baby's lungs, it can cause irritation and inflammation of the lungs. (lancastergeneralhealth.org)
  • The sterile meconium does not predispose to urinary tract infections , but it can cause significant problems if it is inhaled into the lungs. (drgreene.com)
  • It occurs when meconium is present in their lungs during or before delivery. (wikipedia.org)
  • Three main problems occur if this happens: the material may block the airways efficiency of gas exchange in the lungs is lowered the meconium-tainted fluid is irritating, inflaming airways (pneumonitis) and possibly leading to chemical pneumonia. (wikipedia.org)
  • bowel
  • Meconium is normally retained in the infant's bowel until after birth, but sometimes it is expelled into the amniotic fluid (also called "amniotic liquor") prior to birth or during labor and delivery. (wikipedia.org)
  • Meconium is a sticky substance that usually makes up the child's first bowel movement. (wikipedia.org)
  • The meconium, an infant's first bowel movement of digested amniotic fluid, has also been shown to contain a diverse community of microbes. (wikipedia.org)
  • If, on contrast enema, reflux into the dilated distal small bowel loops can be achieved, the study is both diagnostic and therapeutic, as the ionic contrast medium can dissolve the meconium to allow passage of enteric content into the unused colon. (wikipedia.org)
  • infants
  • Review question: Does the administration of surfactant improve lung function and lead to better clinical outcomes in infants born at or near term who have inhaled meconium in or around the time of birth? (cochrane.org)
  • neonatal
  • Research has indicated that neonatal meconium can be used to examine gestational alcohol exposure during the second and third trimesters. (medindia.net)
  • This study extended that research - by examining prenatal exposure to alcohol in seven Italian cities through analysis of FAEEs and of a new biomarker, ethylglucuronide (EtG), in neonatal meconium samples - finding that fetal alcohol exposure is underestimated or misreported in Italy. (medindia.net)
  • The Italian researchers obtained 607 meconium samples from neonatal wards in seven public hospitals located in: Verona and San Daniele del Friuli in the north-east of the country, Reggio Emilia in the middle-east, Florence and Rome in the center, and Naples and Crotone in the south-west of the peninsula.

  • intestinal
  • These compounds, along with ethylglucuronide (EtG), are accumulated by the fetus in meconium, which is composed of amniotic fluid, cells shed by the skin and intestinal tract, as well as other elements during the last two gestation trimesters. (medindia.net)
  • Unlike later feces, meconium is composed of materials ingested during the time the infant spends in the uterus: intestinal epithelial cells, lanugo, mucus, amniotic fluid, bile, and water. (wikipedia.org)
  • Fetal distress during labor causes intestinal contractions, as well as relaxation of the anal sphincter, which allows meconium to pass into the amniotic fluid and contaminate the amniotic fluid. (wikipedia.org)
  • infant's
  • This image compares the appearance of meconium (from 48 hours after normal delivery at term) to the appearance of the same infant's faeces after 1 week of breastfeeding. (wikipedia.org)
  • The infant's skin, umbilical cord, or nailbeds may be stained green if the meconium was passed a considerable amount of time before birth. (wikipedia.org)
  • prenatal
  • If the mother has had less than 5 prenatal visits, has a history of drug abuse, has track marks, has had an abruption, or more than 2 STDS we do both meconium drug screen and urine drug screen. (allnurses.com)
  • A new study has examined fatty acid ethyl esters (FAEEs) and ethylglucuronide (EtG) in meconium samples from public hospitals in seven Italian cities to test for prenatal exposure to alcohol. (medindia.net)
  • liquor
  • None of the group had meconium stained liquor following ingestion, but they all developed diarrhea. (gentlebirth.org)
  • Finally one prospective study looked at 498 'high risk' women and found a higher incidence of meconium stained liquor in those who had self administered castor oil than those who had used enemas or laxatives. (gentlebirth.org)
  • The best way to avoid the problem of meconium stained liquor? (bellybelly.com.au)
  • fetus
  • Meconium is expelled within the first 24 to 48 hours following birth and it can be examined to find all the toxins and xenobiotics accumulated by the fetus. (medindia.net)
  • The Latin term meconium derives from the Greek μηκώνιον, mēkōnion, a diminutive of μήκων, mēkōn, i.e. poppy, in reference either to its tarry appearance that may resemble some raw opium preparations, or to Aristotle's belief that it induces sleep in the fetus. (wikipedia.org)
  • This indicates that the fetus passed the meconium some time ago such that sufficient mixing occurred as to establish the homogeneous mixture. (wikipedia.org)
  • breaths
  • Once your daughter made it safely through her first breaths, the meconium staining was nothing more than a mess to be wiped off. (drgreene.com)
  • birth
  • I've also heard that it is believed to be associated with a higher risk of the baby passing meconium before or during the birth. (gentlebirth.org)
  • or is it possible that had I not gone to hospital & just stuck it out at home for the night and a little bit longer that I would eventually have started to dilate & had a natural birth that was safe for Liam too, even with meconium in my waters? (bellybelly.com.au)
  • No meconium is passed, and abdominal distension and vomiting appear soon after birth. (wikipedia.org)
  • airway
  • 100 bpm), is limp, and has poor muscle tone, the goal is to clear the airway as much as possible to decrease the amount of meconium the baby inhales. (kidshealth.org)
  • exposure
  • In recent years, medical professionals have begun to measure fatty acid ethyl esters (FAEEs) in meconium as a direct and reliable marker of gestational alcohol exposure during the second and third trimesters. (medindia.net)
  • uterus
  • The severity of MAS depends on the amount of meconium the baby inhales as well as underlying conditions, such as infections within the uterus or postmaturity (when a baby is overdue, or more than 40 weeks gestational age). (kidshealth.org)
  • The problem I've heard of with castor oil (besides making you miserable and not always working) is that it can cause the baby to pass meconium in the uterus because the castor oil causes a relaxation of sphincters. (gentlebirth.org)
  • pass
  • I am very interested in what are the physiological mechanisms that could possibly cause the necessary substances to pass to the baby and cause her to pass meconium intrauterinely. (gentlebirth.org)
  • pregnancy
  • If the mother has taken drugs during her pregnancy, it may show up in the meconium and be used as evidence in a protective services case. (allnurses.com)
  • The FAEEs and EtG were measured in meconium and categorized to differentiate between heavy maternal alcohol use during pregnancy and occasional or no use at all. (medindia.net)
  • Meconium can be analyzed to detect the tobacco use of mothers during their pregnancy, which is commonly under-reported. (wikipedia.org)

  • sensitivity
  • The meconium FAEE test is presently the best tool to estimate the incidence and prevalence of FASD as it has high sensitivity and specificity. (medindia.net)
  • For 264 mother/infant pairs with meconium results, sensitivity of self-report was 86% for tobacco, 80% for marijuana and 67% for cocaine. (springer.com)
  • waters
  • This discussion of the use of castor oil made me delve for a dimly remembered Midirs article which examined research on the subject (Dec. 1994- if anyone else wants a read) to try and clarify these meconium muddied waters. (gentlebirth.org)
  • meconium in waters - is it always dangerous? (bellybelly.com.au)
  • When my OB broke my waters there was meconium in them, so the decision was to start me on a drip to induce. (bellybelly.com.au)
  • cases
  • I am totally in support of the meconium testing, even in cases like the one you mentioned, because a red flag should go up when ANY drug use has taken place so that interventions can be made to assist mom in keeping clean and/or being a responsible parent. (allnurses.com)
