Abstract
The demand for pediatric anesthesia has risen in decades, raising concerns about the neurotoxic potential of anesthetics like remimazolam, which may impact neurodevelopment and later cognitive function. This study utilized a neonatal mouse model to assess remimazolam’s neurodevelopmental effects. Results indicate that remimazolam-exposed mice displayed cognitive impairment and depressive behaviors in adulthood. Acute reductions in synaptic protein expression post-anesthesia were observed, along with long-term decreases in hippocampal choline acetyltransferase levels, reduced dendritic spine density in the CA1 region, and microglial proliferation. Collectively, these findings suggest that remimazolam can induce neurotoxicity and neuroinflammation, leading to synaptic dysfunction and associated cognitive and behavioral deficits.
