Newborn hearing screening is an objective, rapid and non-invasive test performed by electrophysiological techniques such as otoacoustic emission, during the baby’s natural sleep or quiet state after birth. The test is usually completed in only 5 to 10 minutes. Babies undergo an initial hearing screening after 48 hours of life; those who fail the initial screening undergo a hearing retest at about 42 days; those who still fail the 42-day retest undergo a diagnostic hearing test at about 3 months of age. Children who are diagnosed with hearing impairment should go to a hospital specialist for appropriate medical intervention in a timely manner. Through newborn hearing screening, early detection of hearing impairment and scientific hearing intervention and speech training are given to eventually make them deaf but not dumb, with the aim of reducing the occurrence of hearing and speech disabilities in children and improving their health. How to care for the newborn’s ears? The etiology of hearing loss is complex, but at least half of hearing loss can be prevented. In this regard, it is recommended that: 1. Eugenics and premarital examination: maternal viral infection and genetic factors during fetal life can cause congenital deafness due to underdevelopment of the inner ear, neonatal asphyxia and severe jaundice due to prematurity and obstructed labor can lead to hearing damage. Therefore, it is important to do premarital checkups, avoid inbreeding marriages, and do perinatal health care for pregnant women and pay attention to the medication during pregnancy. 2, stage hearing check: in general, before full-term, 3 months and 6 months of age, it is best to do at least one hearing check at each stage. Once the baby is found to have a hearing problem, it can be promptly diagnosed and treated. 3. Your baby’s ears are very delicate and need to be protected: no loud noises, no loud stereo or loud TV for hours on end next to your baby. If your baby has a lot of ear wax, you should not help him/her clean it without permission, but seek help from a doctor. 4. Pay attention to observation and care for the ears: If parents find that their child has a hearing impairment, always pay attention to the baby’s behavior at each stage of performance, and if it does not match the stage performance they should pay attention to it and must seek medical attention in time. 5, careful use of drugs to prevent drug poisoning: If the baby is usually sick, be sure to give the baby medication according to the doctor’s prescription, to avoid the abuse of antibiotics. Because some antibiotics are not used properly, it can also cause ear disease. In serious cases, it can cause deafness, and it is difficult to cure drug deafness.
