Exposure to General Anaesthesia in Infancy and Neurocognitive Development (EGAIN)

February 18, 2021 updated by: KK Women's and Children's Hospital

Prospective Cohort Study of Effects of Exposure to General Anaesthesia in Infancy on Neurocognitive Development

This prospective cohort study aims to determine if apparently healthy children with no significant co-morbidities who undergo general anaesthesia for minor surgery before 15 months of age will develop measurable deficits in neurocognitive development compared to apparently healthy children with no significant co-morbidities who do not undergo general anaesthesia or surgery.

Study Overview

Detailed Description

We hypothesize that healthy children exposed to general anaesthesia for minor surgery before 15 months of age will have significantly lower neurocognitive scores at 6,18, 24 and 36 months of age compared with age, and gender matched healthy children from the GUSTO cohort without prior exposure to general anaesthesia or surgery.
