A newborn baby is very delicate and vulnerable to many infections and dependent on the parents for every little thing. The parents also have a high level of curiosity to understand all the new things that happen with the arrival of the baby. Babies are always not all pleasant, the poop and the vomit, the very first faeces of the child are not something familiar to the parents. Apart from the routine, new babies can go through certain other uncomfortable situations too. This article discusses in depth about meconium aspiration syndrome in babies.
Meconium is a medical term that refers to the first stool or the faeces of the newborn. This stool is odourless than the regular ones as the baby only takes amniotic fluid as their intake. The regular stool is yellowish while meconium is green, thick dark and tar-like. Sometimes newborn babies can breathe a mixture of meconium and amniotic fluid into their lungs at the delivery time. Though not very common, this condition can happen.

Meconium refers to the first stool or faeces of the newborn. The MAS or the Meconium Aspiration Syndrome occurs when a newborn is over the due date and inhales a mixture of meconium and amniotic fluid in the lungs at the time of labour or in the womb. This syndrome can be a cause of acute illness and even death in a few newborns.
MAS is due to stress that the foetus undergoes, as a result of which it may pass stool on the womb. This stool is dark green in colour. Post-delivery, the infant will pass meconium stools for the initial few days as well. During delivery, under stress, this meconium mixes with the amniotic fluid which surrounds the foetus. The fetus can breathe this fluid mixture into the lungs before, during or after the birth causing Meconium Aspiration Syndrome.
Even though MAS is not fatal, it can lead to severe health issues for the newborn. And if not treated on time or left untreated can even lead to death.
MAS is the inhalation of the mixture of amniotic fluid and meconium by the foetus into their lungs. This can take place in the womb or during labour. The meconium is a dark green, thick, sticky, stool that has mucus and some intestinal secretions as well. The babies generally pass the first stool either after a few hours of birth or after a few days of birth. Due to destress during labour, the to-be born baby may inhale this mixture of amniotic fluid and faeces resulting in MAS. MAS may lead to respiratory issues and even lead to severe complications or illness.
The Common reasons for the foetal distress and premature releasing of meconium are
The foetus will not produce meconium unless it is in the later stages of pregnancy. As the pregnancy advances to the date, the amount of amniotic fluid also keeps reducing. This can concentrate the meconium as well. Thus, MAS is common in newborn babies that are past 40 weeks. It is uncommon in preterm babies or otherwise.

If the foetus expels meconium inside the womb, the signs and symptoms start to appear in the fetal stage. The infants who inhale meconium during labour show signs within a few hours after their birth. The most common symptom of MAS is respiratory disorder. The infant may either start breathing every heavily or start grunting during breathing. Many newborns can even stop breathing if the airways are blocked by the meconium.

MAS diagnosis takes place depending on the presence of meconium in the amniotic fluid. The doctor will diagnose MAS through the following steps
Any infant who is active, breathing normally and crying at the time of birth needs no treatment even with the presence of meconium in the amniotic fluid. It is however important to keep the baby under observation as MAS symptoms can appear within 24 hours.
The treatment of MAS depends on various factors, like the amount of inhaled meconium, the health of the newborn and the duration of exposure.
In case the newborn shows signs of MAS, like low heart rate, respiratory trouble, poor muscle tone, it must undergo these procedures.
Amnioinfusion is good for babies who have a high risk of MAS due to very limited monitoring resources. A sterile liquid is injected into the amniotic fluid during delivery which helps in dissolving the meconium. It even reduces the inhaled amount of the fluid by the infant.
If the newborn cannot breathe or has a low heart rate, the doctor makes use of a bag and a mask and help them breathe, this will deliver oxygen to the baby and help in inflating the lungs.
The babies who have acute MAS symptoms must undergo the given procedures for better improvement.
Early detection of MAS is the best way to prevent it. Getting monitoring of the foetus through ultrasonography and check-ups can help to assess if the baby is undergoing stress. The doctor can take the necessary steps to get rid of fetal suffering and pain at the time of labour. This even helps in reducing the chances of the development of Meconium Aspiration Syndrome or MAS.
In case the baby is experiencing stress, the doctor can assess and offer treatment to the baby immediately if there are any signs or indicators of MAS.
Here are some precautions you can take to avoid the potential risk of MAS
Most of the overdue newborns who have had MAS do not have long term health issues. Yet MAS is a serious issue and can impact the baby’s health.
Meconium aspiration syndrome in babies is treatable with timely intervention and by taking all necessary precautions. Pregnant women with underlying health issues should undergo regular examination and testing, especially towards the delivery date. Most babies get back to their normal health within a few days post-delivery. Long-term complications are rare but a possibility.
Yes, it is not difficult for the babies to survive meconium aspiration. If left untreated or not treated at time, the results are incurable. If the baby shows breathing disorder and abnormal chest X-ray with MAS, additional oxygen and medical assistance is a must.
Meconium is a cause as well as a sign of less oxygen. In the absence of careful management during labour and delivery or immediately after birth, it can lead to brain injury, cerebral palsy, and permanent disability. If the meconium does not clear from the airways or lungs of the baby, it can have severe consequences and can result in shortage of oxygen, brain injury, less oxygen and death before time.
