Recent studies have shown that sevoflurane can cause long-term neurotoxicity and learning and memory impairment in developing and progressively neurodegenerative brains. Sevoflurane is a widely used volatile anesthetic in clinical practice. Late gestation is a rapidly developing period in the fetal brain, but whether sevoflurane anesthesia during late gestation affects learning and memory of offspring is not fully elucidated. ⋯ HDAC2 inhibitor suberoylanilide hydroxamic acid (SAHA) treatment alleviated all of these changes in offspring rats. Therefore, the present study indicates that sevoflurane exposure during late gestation impairs offspring rat's learning and memory via upregulation of the expression of HDAC2 and downregulation of the expression of CREB and NR2B. SAHA can alleviate these impairments.
