Newborns have short nasal cavity, narrow nasal cavity and rich blood vessels. Compared with adults, they are more prone to inflammation, resulting in children not being able to breastfeed well, fidgeting, crying and breathing with their mouths open. Therefore, it is more important to keep the neonatal respiratory tract unobstructed. Nasal congestion can be treated by the following methods: dropping 1 breast milk into the nasal cavity of children to soften nasal dirt, and then stimulating the nasal cavity with cotton thread to make children sneeze, which is beneficial to discharge secretions; Or gently insert a cotton swab into the nasal cavity with a small amount of water to remove secretions. Pay attention to the action must be gentle, do not use too much force to damage the mucosa, resulting in nosebleeds. For nasal congestion without secretions, a warm towel can be applied to the root of the nose, which can also play a certain role in ventilation. For the treatment of nasal congestion, some drugs can also be used to promote the vasoconstriction of nasal mucosa, but this must be used under the guidance of a doctor, and the frequency and dosage of use should be strictly controlled. Newborns generally need to use it, and at most, they can only use 1-2 drops 1 day, because long-term drug use will lead to dependence and drug-induced rhinitis.
