At present, due to drug poisoning, genetic infection, environmental noise pollution, accidents and other reasons, resulting in many children to produce hearing impairment, of which drug poisoning caused by deafness topped the list. Most of the children with drug toxic deafness are due to the misuse of deafening antibiotics by medical personnel. Due to insufficient knowledge of these ototoxic drugs, not in accordance with the children’s medication dose, too large a dose, too long a course of treatment, resulting in aminoglycoside antibiotic poisoning, resulting in the serious consequences of deafness. It is recommended that parents, in the hospital to the child’s medication, be sure to check the instructions, ask whether it is an aminoglycoside antibiotic, be careful with the medication. The most important thing for children with hearing impairment is early detection, early intervention and early treatment. If the best time for speech is missed, it is difficult to fully restore speech even with hearing aids or cochlear implants. Parents’ lack of attention is the main reason why this happens. One is that parents unintentionally give the child action gestures when communicating verbally with the child, and when they see the child responding, they assume that she has heard them, but in reality the child has not heard them. The other is that some children, when communicating with their parents, will observe the parents’ main intention through the change of their mouth shape, even though they cannot hear their parents’ speech. Hearing function and speech function go hand in hand, so those who are “late talkers” should be on the alert for hearing impairment. Therefore, the child’s late speech must attract the attention of parents, such as found that the child to the age of 1 year is still no speech consciousness, should be alert to the existence of hearing impairment, take the child to the hospital for auditory function examination, strive for early detection, early diagnosis, early treatment. Infants with normal hearing, 4-9 months is an important stage of speech development, while children with severe hearing impairment due to the lack of language stimulation, can not enter into the speech period before 11 months of age, and can not establish a normal language system within 2-3 years of age, and ultimately, the serious will lead to deafness, and the less serious will lead to language disorders, low social adaptability, attention deficits and learning difficulties and other diseases. Through newborn hearing screening, hearing impairment can be detected in time during the neonatal period and early infancy, so that the environment for language stimulation can be rebuilt through sound amplification technology and other methods, so that the child’s language development will be less damaged As people are in the golden period of speech formation before the age of 6, if the deafness is too long, the hearing center has been unable to get the stimulation of sound signals, and its function will be degraded. This degradation is irreversible, and more importantly, too much time can cause degeneration of the speech center, leading to speech disorders and compromising speech intelligibility. Early detection of pediatric hearing impairment, timely hearing compensation measures, and in accordance with scientific methods of speech training and rehabilitation education, these children’s speech, as well as psychological and intellectual development will not be affected, which is known as early intervention for deaf children. The most important thing for children’s hearing impairment is early detection, early intervention and early treatment. If the best time for speech is missed, it will be difficult to fully restore speech even if hearing aids or cochlear implants are fitted.
