If a newborn has bronchiolitis, he or she will exhibit a number of clinical symptoms. First, the prominent symptom is cough. This is because bronchiolitis is caused by inflammation of the airways. Some newborns have a cough that is more phlegmy, while others have a dry cough. Next, other accompanying symptoms appear. In addition to coughing, newborns with bronchitis may have a stuffy nose, runny nose, fever, etc. For bronchitis in newborns, parents should promptly treat the newborn with phlegm and cough. For example, apply aminoglutethimide oral solution, or apply nebulized inhalation treatment. Anti-infection treatment should be given to newborns in a timely manner because the root cause of bronchitis is various pathogenic bacteria. If it is caused by mycoplasma, parents should promptly apply erythromycin to the newborn for anti-mycoplasma infection treatment.
