Gut Microbiota Influences Developmental Anesthetic Neurotoxicity in Neonatal Rats.
Anesthetic exposure during childhood is significantly associated with impairment of neurodevelopmental outcomes; however, the causal relationship and detailed mechanism of developmental anesthetic neurotoxicity remain unclear. Gut microbiota produces various metabolites and influences the brain function and development of the host. This relationship is referred to as the gut-brain axis. Gut microbiota may influence developmental anesthetic neurotoxicity caused by sevoflurane exposure. This study investigated the effect of changes in the composition of gut microbiota after fecal microbiota transplantation on spatial learning disability caused by developmental anesthetic neurotoxicity in neonatal rats. ⋯ The alternation of gut microbiota after fecal microbiota transplantation influenced spatial learning ability in neonatal rats with developmental anesthetic neurotoxicity. Modulation of the gut microbiota may be an effective prophylaxis for developmental anesthetic neurotoxicity in children.
