Nasal congestion is a common condition in infants’ respiratory system. Once the infant’s nasal cavity is attacked by a lesion, it will secrete a lot of mucous secretions and the nasal mucosa may swell, and its incidence is higher than that of children and adults. Nasal congestion can lead to poor breathing, irritability, sleep disturbance and difficulty in feeding infants. Because infants do not breathe through their mouths, bilateral nasal congestion can easily cause their poor breathing and even induce adverse consequences such as asphyxia, so families should promptly deal with infant nasal congestion. Infant nasal congestion can be unblocking the nasal cavity to restore ventilation. For example, use cotton swabs to gently roll out the nasal secretions, or use a nasal aspirator to suck out the abnormal secretions. Because of the short duration of action of ephedrine and other drugs for infants, and the adverse effects are large, which can lead to accelerated heart rate in infants, repeated use in the short term can cause toxic effects on the cardiovascular system, and there is some damage to the nasal mucosa, so the drugs are mostly applied externally to the infant’s fontanelle, for medication. In addition, the baby’s nasal congestion is mainly related to the cold or was infected with the cold virus. So usually do a good job of care, avoid getting cold, do not contact sick family members, family members with a cold should wear a mask to prevent infection to the baby.
