What Are the Effects of Newborns Inhaling Meconium at Birth?

Question

Does inhaling meconium at birth affect a newborn’s lungs? Are there any complications?

Answer

The lungs are primarily used for breathing, where oxygen is inhaled through the tiny alveoli in the lungs and enters the bloodstream. This oxygen-rich blood then circulates throughout the body, including to the brain. The body’s metabolic byproduct, carbon dioxide, is then expelled through the lungs. If there is an infection in the lungs, the exchange surface area of the alveoli decreases, affecting the overall blood and oxygen supply to the body, especially the brain which is highly sensitive to this. As for complications, it is difficult to determine at present; generally, recovery is quick, and the likelihood of complications occurring is relatively low.
