Heavy breathing in babies is usually due to adenoid hypertrophy, sleeping on their backs, pneumonia or respiratory tract infections, or narrowing of the airway, which can usually be treated with medication and generally has a good prognosis. Common causes and treatment 1, adenoid hypertrophy: resulting in poor ventilation, resulting in the symptoms of heavy breathing in babies. If the baby’s nasal congestion is serious and affects breathing, furacilin ephedrine nasal drops can be used cautiously under the guidance of a doctor, but it should be noted that ephedrine has side effects on small babies and is not suitable for excessive or long-term use, so as not to cause atrophic rhinitis and affect the olfactory sensitivity of the nose; 2, supine sleep: when the baby sleeps in the supine position, the phenomenon of the tongue root falling back can occur, and if the throat breathing channel is blocked, the phenomenon of heavy breathing can occur. This situation can be replaced, such as taking the side position, can alleviate such symptoms; 3, respiratory inflammation: if the baby is cold, allergies, or bacterial, viral infections can lead to respiratory symptoms, such as cough, nasal congestion, runny nose, etc., which leads to the baby’s breathing heavy symptoms. If the infection is caused by bacteria, anti-inflammatory treatment with anti-infective drugs can be applied as prescribed by the doctor. If it is caused by viral infection, antiviral drugs can be applied for treatment; 4, congenital structural abnormalities: some babies can have symptoms of heavy breathing sounds due to congenital factors, such as laryngeal cartilage dysplasia, laryngeal tissue relaxation, and laryngeal tissue collapse during inspiration. In mild cases, balloon dilation can be performed under tracheoscopy to open the narrowed airway. If the airway is narrowed to a greater degree, a stent will be placed for treatment.
