In the middle of the night, a sleeping baby suddenly cries loudly, and if he or she is picked up, the crying is reduced or stopped. This is often a sign that the child has otitis media. In infants and children with vomiting and upper respiratory tract infections, especially when accompanied by nasal congestion, nasal secretions with viruses and bacteria will flow into the middle ear and cause otitis media. This is characterized by localized pain and fluid exudation from the ear cavity, and in severe cases, pus, and often fever. When the child is lying down, the exudate collects in the ear chamber, which raises the internal pressure and causes severe pain; when the baby is held upright, the exudate flows out into the nasal cavity, the pressure inside the ear chamber decreases, and the pain is relieved. Since otitis media is a common and frequent disease in children, and the winter and spring seasons are the high incidence period, and it is closely related to upper respiratory tract infection in children, it usually develops within 48 hours secondary to upper respiratory tract infection, and the duration of the disease does not exceed 12 weeks. The treatment of acute otitis media in children includes etiology and symptom treatment. Its etiological treatment is mainly the application of antibacterial drugs, combined with other symptomatic treatment, etc., for comprehensive treatment. According to domestic and foreign clinical practice experience, broad-spectrum amoxicillins are used, and the course of treatment is usually 7-10 days. Topical treatment includes the use of ear drops, nasal sprays, etc. Otitis media will cause hearing loss or even deafness in babies if left untreated. Since infants and toddlers are not able to speak, they often have more severe cases by the time they are detected, so prevention should be the main focus: 1. 2. When a child has a cold with nasal congestion, although there is no fever, the baby’s nasal passages should be kept open in time. Oral drops are available, which can effectively relieve nasal congestion caused by colds and other reasons, and can prevent otitis media complicated by upper respiratory tract infections, without any obvious side effects.
