There are some patients who feel dizzy and nauseous after using ear drops. This is because the temperature of the ear drops is too low. The human ear is divided into three parts: the outer ear, the middle ear and the inner ear. The vestibular organ of the inner ear is very sensitive to cold stimulation, so when the temperature of the ear drops is too low, it will break the temperature balance of the inner ear, and when the vestibular organ of the inner ear is stimulated by cold, it will cause vertigo and nausea. Therefore, in order to avoid stimulating the vestibular organs of the inner ear, it is best to keep the temperature of the ear drops in line with the body temperature. When using ear drops in a low temperature environment, you can hold the bottle in your hand for a while or put the bottle in warm water at about 40 degrees Celsius to warm up the ear drops, and when the temperature of the drops is close to your body temperature. Shake it well and then use it. On the one hand, the ear canal does not adapt to high temperature liquids, so high temperature will burn the mucous membrane inside the ear; on the other hand, the drug components of ear drops will decompose under high temperature, which will reduce the effectiveness of the drug. If you are suffering from purulent otitis media, wipe the purulent secretions with sterilized cotton swabs before applying the drops, or use 3% hydrogen peroxide to thoroughly wash the pus and secretions in the external ear canal and the scarf ear cavity. When rinsing, the rinsing solution used can also be warmed up. After rinsing, swab the outer ear canal with sterilized cotton swabs, and then drop the medication to maximize its efficacy. Some drug instructions clearly require an ear bath for about lO minutes after the ear drops. What is meant by an ear bath? In simple terms. An ear bath is when the medication is inserted into the ear canal and soaked for a period of time to allow the mucous membrane in the ear to fully absorb the medication for the purpose of local treatment. This is similar to giving the ear a bath. The ear bath requires a side-lying position with the opening of the external ear canal of the affected ear upward. The drops are placed into the external ear canal and filled as much as possible and left for 10 minutes, and then the position is changed so that the medication flows out.
