Most bloody ear leaks are related to trauma, but be on the lookout for hemangioma or middle ear cancer. In particular, middle ear cancer is ominous when there is blood in the pus, its pus has a foul odor, or there is severe earache or headache. Suspicious tissues in the external auditory canal or middle ear should be taken for pathologic examination to determine the diagnosis and treatment measures. Prevention of bloody ear leakage should actively prevent and treat upper respiratory tract infections. It should also actively treat chronic inflammation of the nose and throat, such as chronic tonsillitis. Pay attention to keep the ear clean. Do not pick your nose. Prevention of tympanic membrane trauma, tympanic membrane trauma has not been healed or old perforation should not swim, bathing must prevent water into the ear. Breastfeeding mothers should correctly grasp the breastfeeding posture, when breastfeeding the baby should be picked up, so that the head upright. If there is too much milk, the speed of outflow should be properly controlled. Warm, moist dressings, heating pads or hot water bottles should be applied to the patient’s ear to reduce inflammation and pain. Use a tampon to gently clean the ear or apply topical medication. Store ear drops at room temperature; cold drops can cause the patient to become dizzy. If the patient is hearing impaired, make sure everything is explained and understood by the patient. If necessary, convey information through writing. When examining or cleaning a child’s ears, remember. The external ear canal is horizontal and the ear canal must be pulled back and down. During the ear examination, have the child sit on the parent’s knee to limit movement so that the ear to be examined is facing the examiner. Have the child catch one arm around the parent’s anterior waist and drape the other arm at his or her side, then ask the parent to assist in keeping the child in position. If the doctor is alone with the child. Have the child assume a prone position with arms at the sides of the body and turn the head sideways so that the involved ear faces the ceiling. The examiner’s body is bent toward the child, and the child’s upper body is secured with your elbow and upper arm. Patients with chronic ear infections are advised to avoid blowing their nose hard when they have an upper respiratory infection. This will prevent infected secretions from entering the middle ear. Advise the patient to blow his or her nose with the mouth open. Patients are also reminded to clean the ear canal with a towel only. Avoid inserting anything into the ear (such as hairpins or cotton swabs) that could cause damage. If the patient is a swimmer. Advise them to wear earplugs during swimming and to keep their ears thoroughly clean and dry after swimming. Tell the patient to be aware of recurrent ear pain and ear effusion, especially if there is no upper respiratory tract infection, as this may be a sign of a tumor. Tell patients with eardrum perforations that such perforations often heal spontaneously. Patients should then be cautioned to avoid leaving their head unattended in the water during the recovery period. Advise the patient to insert a lubricated cotton ball into the ear canal before showering.
