Brief summary
The long-term effect of general anesthesia on developing brain is the focus of clinicians when infants exposed to general anesthesia for a long time during operation. A retrospective study showed that children exposed to long-term or repeated operations, the anesthetics had a higher incidence of cognitive impairment in adolescence than those did no. When infants with hearing impairment undergo bilateral cochlear implant surgery, they are at high risk of long-term neurobehavioral abnormalities caused by anesthesia. In this study, investigators intend to observe the long-term behavioral abnormalities of hearing-impaired infants after intravenous or inhalation anesthesia by a ambispective cohort study.
Detailed description
Gesell development scale contains five subscales including adaptability, fine motor, gross motor, language, and social skill evaluation. Developmental quotient (DQ) = (development age/actual age)×100. Total DQ is the average of five DQ of subscales. DQ≥86 is normal, 76≤DQ≤85 is suspicious, 55≤DQ≤75 is mild neurological damage, 40≤DQ ≤54 is moderate neurological damage, 25 B DQ B 39 is severe neurological damage, and DQ\< 25 is very severe neurological damage.
