Drug-induced deafness treatment and rehabilitation

The key to the treatment of drug-induced deafness is early detection and early treatment. In the process of using aminoglycoside antibiotics such as gentamicin, it is necessary to detect early signs of hearing loss, vitamin A 25000U, vitamin B, adenosine triphosphate, coenzyme A, cytochrome C, etc. The metabolic process, vitamin A can promote the growth of the neuroepithelium, generally after the above treatment, the hearing can remain stable and will not continue to decline.

Infants and young children have many chances of getting sick, sometimes with a large dose of aminoguanidine antibiotics, and the children are generally weak, so the chance of ear poisoning is more than that of adults. When children have deafness, they will not complain, and parents need to pay attention to observe early detection. Early administration of neurotrophic drugs, sometimes with hormone therapy. We have found cases of deafness, rescuing treatment, and complete recovery of hearing after overdose of gentamicin. For infants and young children, it should be treated actively. Because infants and young children are in the growing season, they are vigorously developed and have strong vitality.

For those who use conventional doses of aminoguanidine antibiotics, the hearing progress is progressive, and vitamins and neurotrophic drugs should be given for a longer period of time. Generally, 3–6 months, 6 months after the drug interval is extended until the hearing is stable. until. For accumulative poisoning, generally only high-frequency hearing loss, the symptoms are relatively light, after treatment, some may be partially restored. In clinical application, Chinese herbal medicines have also been found to have certain curative effects, such as Huang Jing, Atractylodes Rhizome, Rhizoma Drynariae, Gardenia, Mulberry, Astragalus, Ligustrum lucidum and Salvia miltiorrhiza.

Recent studies have found that the physiological function of the injured cochlea may be restored. It is believed that the drug can be excreted from the lymphatic and cochlear cells in the inner ear. The submicrostructure of the cochlear hair cells can be repaired, the vascular pattern has reversible changes, and the hair cells are expected. regeneration. In view of the findings of the above basic research, it shows a bright prospect for the treatment of toxic sputum in drugs.

For patients with deafness who are ineffective in medication or whose hearing tends to be stable, they should actively use hearing and speech rehabilitation measures to improve their hearing and speech communication. For children, avoid dumbness.

There are three main types of rehabilitation measures that are currently effective:

One is to choose the right hearing aid. Before the selection, the hearing threshold and the maximum comfort threshold of the patient corresponding to different sound frequencies should be tested to determine the hearing dynamic range of the patient. In patients with drug-induced deafness, the inner ear auger is damaged, often accompanied by re-vibration, the dynamic range is narrowed, and the tolerance to strong sound is reduced. Therefore, when selecting a hearing aid, attention should be paid to the maximum output limit, automatic gain control or Wide dynamic range compression and other functions, which can protect the patient’s existing hearing and achieve better rehabilitation.

The second is cochlear implant. For extremely severe swearing people, their speech frequency average hearing threshold is often more than 90 decibels, wearing hearing aids is less effective, because the inner ear sensory cell damage seriously hinders the transmission of auditory information, although the external amplified sound is natural and clear, the patient’s The central auditory system cannot receive enough information. The cochlear implant is an electronic device that replaces the human ear function. It converts the received sound into a coded electrical signal and transmits it to the transmission coil. The transmission coil transmits the signal to the subcutaneous receiver/stimulator through the magnetic coupling. The stimulator decodes the signal to the electrodes implanted in the cochlea, causing the nerve fibers to excite and transmit sound information to the brain, producing hearing. Through cochlear implants, patient hearing can be improved to near normal levels, thus laying the foundation for learning the language.

The third is the extremely severe person who has no economic ability to cochlear implants. It can improve his social communication ability by wearing an auditory alternative device-vibration sensation device. The device can change the incoming sound into a vibration signal and perceive the patient through the skin. Through this device, the patient can not only feel the presence and response of the ambient sound, such as: car sound, knocking sound, telephone sound, etc., but also can be combined Seeing words (lip reading) improves the ability to recognize words. All of the above rehabilitation measures require listening training and speech training to achieve the best hearing and speech rehabilitation.
