The following measures can be used to improve the situation of the newborn’s snotty nose and poor breathing: first of all, the newborn can be cleaned with a cotton swab in the nasal cavity, because the newborn’s snotty nose is mainly due to cold, due to the nasal secretion is more, which leads to the newborn’s nasal congestion and poor breathing. Parents or doctors can dip a cotton swab into a small amount of water and place it in the newborn’s nasal cavity, gently rotating the swab can absorb the snot on the cotton swab, thus making the nasal cavity smooth. Secondly, physiological sea saline can be used to clean the nasal cavity of newborns, because the osmotic pressure of physiological sea saline is basically similar to that of the nasal cavity, and the irritation to the nasal cavity is very mild. Parents or doctors can put physiological saline in the nasal cavity of newborns, which can effectively improve the symptoms of excessive nasal discharge and breathlessness.
