Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
