ABSTRACT

Objective To share the analysis results of follow -up after treatment of hyperbilirubinemia hear-ing .Methods 573 cases of neonatal hyperbilirubinemia by jaundice intervention method was divided into exchange transfusion group (67 cases ,bilirubin concentration range of 344 .2~1 107 .2 μmol/L ,457 .9 μmol/L on average) and therapy group (506 cases ,bilirubin concentration in the range of 205 .2~ 572 .6 μmol/L ,average 285 .2 μmol/L) .The auditory brainstem response ,distortion product otoacoustic emission hearing detection and immittance method were used .The two groups of hearing loss were compared with 836 cases of normal controls .Results The observation group showed that hearing disorder morbidity rate was 3 .49% (20/573) ,for the control group ,the hearing loss morbidity rate was 0 .24% (2/836) .There was a statistically significant difference between the two groups (P<0 .05) .For the exchange transfusion group ,hearing losses accounted for 25 .37% of the overall change (17/67) .For the phototherapy group ,the hearing losses accounted for 0 .59% of the overall (3/506) phototherapy , showing statistically significant difference between the two groups (P<0 .05) .There were hearing impairment with bilateral severe (80% ,16/20) and retrocochlear lesions (65% ,13/20) .Conclusion The bilirubin concentration in blood transfusion for the children tended to have hearing impairment ,more in bilateral severe and retrocochlear le-sions ,hearing loss was irreversible .
