P24: Neonatal aspiration syndromes

Neonatal aspiration syndromes are a group of conditions that occurs in newborn babies when they breathe in food, fluids, or other substances into their lungs. This can happen during labor and delivery or shortly after birth, most typically when a baby aspirates amniotic fluid, meconium (the baby's first stool), or milk. The inhaled substances can irritate the baby's lungs, causing them to swell and, in some cases, leading to respiratory problems like difficulty breathing. Common symptoms can include a bluish skin color, rapid or labored breathing, or a reduced heart rate. The progression of these conditions can vary widely, from mild respiratory discomfort to severe breathing difficulties that require immediate medical intervention. The respiratory system is primarily impacted by these syndromes, though other body systems may be affected in severe cases.
