Dexmedetomidine Inhibits Inflammation to Alleviate Early Neuronal Injury via TLR4/NF-κB Pathway in Rats with Traumatic Brain Injury.

Purpose - This study aims to explore the potential mechanism of dexmedetomidine in terms of inhibiting inflammation to alleviate early neuronal injury via TLR4/NF-κB pathway in rats with traumatic brain injury. Methods - The model of brain injury was established in rats. After the model was established, the rats were randomly divided into five groups: Sham, Sham + DEX, TBI, TBI + vehicle, and TBI + DEX.
