Option 3 : It does not progress to persistent pulmonary hypertension in severe cases 

Concept:

  • Meconium is called as first passed stool
  • Meconium will be tarry black and smooth
  • It is passed by the child within 24 hours of their birth
  • Some times due to prolonged labour and many other conditions meconium will be passed inside the womb
  • Passed meconium can be aspirated by the children
  • It can cause breathing difficulty and aspiration

  • Respiratory distress -> reduced respiratory rate and function
  • Asphyxia -> where the child will nor get enough oxygen during the process of delivery
  • Cyanosis is a common clinical finding in newborn infants
