How often is meconium present in births?

How often is meconium present in births?

• A. Up to 25%
• B. 10%
• C. 40%
• D. 5%

Answer: (A)

Meconium in the amniotic fluid is a fairly common finding, especially as gestation extends. It is present in up to about one quarter of births, with higher rates in term or post-term pregnancies and when there is fetal stress. Knowing this helps you recognize that while not every birth has meconium, its presence is not rare and carries implications for newborn airway management and monitoring for meconium aspiration risk. The smaller percentages (ten or five percent) understate how often it can occur, while a value as high as forty percent is not typical in most populations.
