It is normal for patients to not be able to hear after the sodium bicarbonate ear drops, because the ear is filled with the drops, which can lead to sound conduction problems, so patients will not be able to hear the sound. In terms of treatment, it is recommended that the patient turn on his side with his ears facing downward and tug on the auricle to effectively clean the sodium bicarbonate ear drops inside the patient’s ear canal, after which it is recommended that the patient dip a cotton swab inside the ear canal to effectively absorb the sodium bicarbonate ear drops, and the patient’s inability to hear will improve after active treatment. In clinical practice, sodium bicarbonate ear drops are often used in patients with cerumen embolism, mainly for softening. 2-3 times a day, each time the ear bath is performed for about 11 minutes, which can effectively play a role in softening cerumen. After that, the patient can go to the hospital and let the doctor remove the softened cerumen inside the ear thoroughly with an aspirator under the endoscope. The patient’s condition will definitely improve after active treatment.
