Objective:Analyze the ABR testing results of local infants who failed the hearing screening and summarize its characteristics.Method:Carry on the first ABR test to 140 infants who failed the newborns′ hearing screening when they are about 3-month age, the unusualities carry on the second ABR test at about 6-month age, and carry on the statistical analysis.Result:One hundred and forty infants with the first ABR diagnosis,65 infants are normal, accounting for 46.43%; 75 infants have single or binaural ear hearing disorder, accounting for 53.57%, single ear 17.14%, binaural ear 36.43%, of which mild hearing disorder takes most, accounting for 27.14%, the profound hearing loss is also not extremely rare, accounting for 14.29%; Between male and female hearing disorder disease incidence rate difference is not remarkable statistics significance(P0.05); Between the number of high-risk in the hearing injury and non-high-risk after the comparison difference is not remarkable statistical significance(P0.05); With the population of above severe loss in hearing high-risk has the remarkable statistical significance with the non-high-risk comparison difference (P0.05). The second ABR subsequently visit 38 infants, 8 infants normal, total normal rate 52.14% (73/140), 16 infants mild hearing disorder 10 infants transfer normal either the change for the better, 6 infants do not have the change or the aggravation, 3 infants moderate hearing disorder 1 infant changes for the better, 2 infants do not have the change, 9 infants severe hearing disorder 3 infants have the change for the better, 3 infants do not have the change, 3 infants aggravate, 10 infants profound hearing disorder 9 infants do not have the change or the aggravation extremely, 1 example brain paralysis profoung hearing disorder extension converges normally extremely; The non-high-risk whose hearing changes for the better is obviously higher than high-risk(P0.05).Conclusion:Should develop newborns′hearing screening comprehensively with key attention to high-risk loss of hearing; The severe hearing disorder has the variability, and so on exceptional child hearing situation appraisal should be prudent to the brain paralysis; should establish perfect tracing, revisiting and manageing system as soon as possible.
