Overview
Brief Summary
Numerous preclinical evidence has confirmed that most commonly-used general anesthetics can affect neurodevelopment of young animals adversely, causing both structural defect of brain and cognitive impairment. However, it is unclear at present whether such effect would also occur to children exposed to general anesthesia in their early life. Several observational clinical studies and one interventional clinical trial indicated that short-time general anesthesia less than 80 minutes might be safe to cognitive development. Concerning long-time and/or multiple anesthesia exposure, some studies supported its association with long-term cognitive defects, while other studies did not. These studies are mainly retrospective or ambirectional researches. We have designed a prospective, multicenter cohort study to examine the neurodevelopment of infants exposed to anesthesia before age 2 in the first year after surgery, and compare the neurodevelopment status of infants exposed to anesthesia less than 3 hours and those more than 3 hours. The Gesell Developmental Inventory (GDI) and several neuropsychological testing batteries will be used. The anticipated outcome of the study will add reliable evidence from Asians to elucidate the relationship of anesthesia and long-term neurodevelopment of infants.

Arms & Interventions
Long-time anesthesia exposure
Infants receive general anesthetics longer than 3 hours in total.
Intervention: General Anesthetics
Short-time anesthesia exposure
Infants receive general anesthetics shorter than 3 hours in total.
Intervention: General Anesthetics
Outcomes
Primary Outcomes
Change of the developmental quotient of the Gesell Developmental Inventory
Time Frame: From baseline before anesthesia to 1 year after anesthesia
The Gesell Developmental Inventory has been translated into Chinese and standardized by the Beijing Children's Health Care Institute and the performance results are expressed as a developmental quotient (DQ).
Secondary Outcomes
- Change of the standardized score of the Social Maturity Scale(From baseline before anesthesia to 1 year after anesthesia)
- Change of the standardized score of the five domains of the Gesell Developmental Inventory(From baseline before anesthesia to 1 year after anesthesia)
