Effects of intracisternal dexmedetomidine on cerebral neuronal cells in rat: a preliminary study

Abstract: AIm:The aim was to investigate whether dexmedetomidine had a toxic effect on cerebral neurons when it was administered centrally into the cerebrospinal fluid by the intracisternal route. mAterIAl and methOds: Eighteen rats were anesthetized and the right femoral artery was cannulated. Mean arterial pressures, heart rates, arterial carbon dioxide tension, arterial oxygen tension, and blood pH were recorded. When the free cerebrospinal fluid flow was seen, 0.1 ml normal saline (Group SIC, n=6) or 9 µg/kg diluted… Show more

“…Therefore, NA and α 2 -adrenergic drugs influence the release of numerous other neurotransmitters, including 5-hydroxytryptamine (5-HT), dopamine and acetylcholine (46). The concomitant use of the peripherally acting α 2 -AR antagonist MK-467 in dogs treated with DEX prevented major changes in plasma glucose, insulin, non-esterified fatty acids and lactate (47). These results indicate that DEX inhibits insulin secretion through an α 2 -AR and pertussis toxin-sensitive trimetric G protein-binding protein pathway, which involves the activation of the K + channel and inhibition of the Ca 2+ channel (48).…”
