summary

I took some medicine last month, but it's a little better. It's not all right. I often use my nails to remove them. I'm infected again. Recently, my ears are bleeding. The ear has otitis media. After treatment for a period of time, I feel much better now. About how otitis media is caused, let's talk about how otitis media is caused.

How is otitis media caused

Reason 1: acute otitis media is an acute suppurative inflammation of the middle ear mucosa, and the most common infection is through eustachian tube. After a cold, pharyngeal and nasal inflammation spread to the eustachian tube. The pharyngeal orifice and lumen mucosa of the eustachian tube appeared hyperemia and swelling. Cilia movement was obstructed. Pathogenic bacteria invaded the middle ear and caused otitis media.

Reason 2: otitis media to swim should avoid the water pharynx in the mouth, in order to avoid water through the nasopharynx and into the middle ear, cause otitis media. The external auditory canal can be blocked with sterilized cotton ball to avoid infection induced otitis media.

The third reason: lack of cerumen: because the cerumen of normal people's external auditory canal is slightly acidic and has anti infective effect, when lack of cerumen, the external auditory canal will lose its antibacterial acid coat, so it is easy to cause disease.

matters needing attention

Warm reminder: family nursing measures for patients with otitis media: if the ear of a child with otitis media has pus, clean his ear canal with 3% hydrogen peroxide first, and then drop the medicine. The child should lie on his side after dropping the medicine and get up again after the medicine has penetrated into the tissue.
