Aspiration pneumonia in newborns usually manifests as choking cough, dyspnea and fever. 1. Choking: neonatal pneumonia is mostly inhalation, such as inhalation of amniotic fluid, meconium, breast milk, etc. As the airway is blocked by secretions, choking, choking, coughing and violent coughing are likely to occur, and in severe cases, asphyxia can be caused. 2. Difficulty in breathing: Difficulty in breathing is one of the early symptoms of aspiration pneumonia. Due to a large amount of fetal feces, amniotic fluid or breast milk inhalation to the lungs, resulting in respiratory tract obstruction, affecting the function of gas exchange, heart rate acceleration, decreased oxygen saturation, respiratory distress, asphyxia and other conditions. 3. Fever: Due to the imperfect development of lung function, inhalation of secretion can easily lead to lung injury, cough, fever, poor spirit, poor appetite, body temperature is usually around 38~39℃. Aspiration pneumonia in newborns is a more serious disease and should be treated promptly under the guidance of a doctor.
