Is Terminal Meconium
Can terminal meconium give a baby a blackeye and a swollen. Head that causes neonatal hyperbilirubinemia?
Swallowed AF, cells: As a fetus grows, its organs and systems mature in preparation for functioning after birth. One such system is the gastrointestinal GI system. A fetus swallows amniotic fluid and its contents through pregnancy, and the "end" product literally is meconium, a dark green slimey substance. If baby's near term, it might pass a little and be ok. If early or stressed, it could breath it in and need help. ...Read more
Meconium drug test: Meconium drug screens on newborns have a window of exposure for up to 20 weeks. ...Read more
?: Please rephrase your question, it is not clear what you are asking. ...Read more
Peculiar wording???: Meconium starts forming after the gut is complete. This is around 12 weeks. It accumulates slowly, and represents gut enzymes, liver discharge, swallowed hair and skin. It will usually not empty until after the baby is born. ...Read more
Yes: If your case is being followed by child services, it is routine for urine and meconium to be screened for evidence of drug use under directives of the state. Meconium is made over weeks and months and will be positive for many weeks after use. It is best that you make plans accordingly and be honest when questions are asked. It will go better for you if you do. ...Read more
As often as needed: Meconium drug testing is often done to validate a positive drug screen in the mother or newborn as the method is not confused by some innocent otc preparations. It can also demonstrate drug use over the months prior to birth where a urine test may miss those not used within days of birth. ...Read more
Confusing question: All newborns will pass meconium. It is the accumulated fecal debris of pregnancy consisting of bile, digested hair, shed cells and protein debris in a stacky mass. After its passage, it is gone and transitional or regular stools form. Kids who suck some meconium into their lungs before or during the birthing process can have variable outcome based of the amount and degree of damage the material cause. ...Read more
? never heard of it: I've been in the business of caring for babies a long time and never heard of anyone relating meconium to gestational age. It starts forming after 12 weeks or so and stops at delivery. Post term status is most often apparent by physical exam of the baby. ...Read more
Months: Suspicion leads to meconium testing in a newborn as a more accurate reflection of past drug exposure than urine, that may only reflect a week or so. The material is built up over many months and the sensitivity of the test can pick up minute quantities deposited in the meconium as it forms. This reflects exposures from the preceding month if not longer. ...Read more
Depends: I'll assume u mean inhaled meconium that caused respiratory pbs. The effect is variable. Even small amts in the lung can cause a chemical pneumonia that interferes with breathing. After the pneumonia improves under rx, there can be tissue scarring from the stress, the meconium is eventually broken down & removed by the healing process. The lung injury will gradually improve, some probs may remain. ...Read more
Varies: Depends on the hospital and lab. If they have to send it out, may take longer. Should be less than a week ...Read more
Too long: It may take up to 7 days. Most hospitals have to send it out to a major center for analysis. What are you looking for? ...Read more
OK: If infant passed meconium before birth and swallowed it-infant will be fine-it is sterile. But if infant breathed it into lungs-infant can have serious pneumonia. 12% of births have meconium-sometimes it is a sign of fetal distress-sometimes not. The condition of the infant right now is important. If there is no breathing problem-that is a good sign. ...Read more

Months if ever: The meconium begins to form at 12 weeks and may carry traces of discarded debris for months. The higher the exposure the more likely the material would show up on the gas chromatograph used for testing. ...Read more
Meconium Aspiration: Meconium aspiration is when the fetus has a bowel movement before birth and swallows some of the bowel movement before birth. This may result in the condition of Meconium Aspiration Syndrome at birth, associated with Respiratory Distress requiring Ventilation and Medical Support. ...Read more
Meconium staining: Sometimes, however, a baby has a bowel movement before or during birth. If this happens, the amniotic fluid released when the mother's bag of water breaks will have a greenish tint. At times when the baby is not getting enough oxygen before or during birth, the baby may take a breath and inhale some meconium, which can irritate the baby's lungs and cause lung problems that can be severe. ...Read more
Respiratory distress: Meconium aspiration syndrome (mas) occurs when an infant delivers via meconium stained amniotic fluid which travels into the lungs and causes respiratory distress. You must exclude other forms of respiratory distresss. Mas can be mild to severe. Severe forms can lead to severe lack of oxygen and respiratory failure. It can occur in 20-30% of meconium stained deliveries. Treatment is in the nicu. ...Read more

As long as a baby hasn't pass all meconium, it can be in there.
Please, don't use Cocaine or other drugs during your pregnancy for the reason of possibility of neonatal abstinence syndrome in your baby. Your baby might suffer from the bad withdrawal same way as adults do, but worse, since he/she couldn't do anything about it and they are just victims of maternal drug use. ...Read more
Respiratory distress: Meconium is the production the baby expels from the colon and rectum that built up while in utero. When meconium is expelled in utero and the baby's first breath results in inhaling into the lungs, the baby cannot absorb oxygen well. Sometimes we can suction it from nose, mouth and trachea and the baby will be fine. Sometimes, it is so severe, the baby needs mechanical ventilation or ecmo. ...Read more
Usually nothing: Meconium aspiration syndrome can lead to a very ill (or not) baby at birth but provided the baby receives appropriate care, there are no usual long term side effects. ...Read more
Quite a while: Meconium begins to form around the 12th week of pregnancy and material deposited within may accumulate from that point forward. Early exposures may go undetected by testing, yet it can go back and show exposures a month or more before delivery. The gas chromatography used for this study can pick up faint traces of material and is quite specific about type of agent detected. ...Read more
