Meconium aspiration syndrome
Meconium Aspiration Syndrome
Meconium Aspiration Syndrome (pronounced: meh-KOH-nee-uhm as-puh-RAY-shuhn SIN-drohm), often abbreviated as MAS, is a medical condition that affects newborn infants. It occurs when a newborn breathes a mixture of meconium and amniotic fluid into the lungs around the time of delivery.
Etymology
The term "meconium" is derived from the Greek word "mekonion" which means "poppy juice" or "opium-like", referring to the dark, greenish-black color of the substance. "Aspiration" comes from the Latin word "aspirare" meaning "to breathe in". "Syndrome" is derived from the Greek word "syndromē" meaning "concurrence of symptoms, concourse of things running together".
Definition
Meconium is the first stool of an infant, which is typically passed in the womb during early pregnancy and again in the first few days after birth. In some cases, the infant may pass meconium while still in the womb, usually due to stress or a lack of oxygen. If the meconium is present in the amniotic fluid and the baby inhales it, this can cause MAS.
Symptoms
Symptoms of MAS can vary, but may include cyanosis (a bluish color of the skin and mucous membranes), rapid breathing, tachycardia (a fast heart rate), and grunting sounds with breathing. In severe cases, MAS can lead to pneumonia, respiratory distress syndrome, or pulmonary hypertension.
Treatment
Treatment for MAS typically involves supportive care, including oxygen therapy and, in severe cases, mechanical ventilation. Medications may also be used to help manage symptoms and complications.
