Dexmedetomidine 53-68 CCAAT/enhancer binding protein zeta Rattus norvegicus 112-116 21596884-10 2011 In normovolemia, dexmedetomidine significantly decreased rCBF (-58%) in the lateral cortex with a similar percentage decrease (-57%) of calculated O(2) consumption. Dexmedetomidine 17-32 CCAAT/enhancer binding protein zeta Rattus norvegicus 57-61 21596884-13 2011 In contrast, in the lateral cortex of the dexmedetomidine-treated rats, the decrease of rCBF was not significant but there was a significant decrease in regional cerebrovascular resistance. Dexmedetomidine 42-57 CCAAT/enhancer binding protein zeta Rattus norvegicus 88-92 21596884-15 2011 Despite significantly lower rCBF (-34%) in the dexmedetomidine-treated rats, the Svo(2) was similar between the normal saline-treated (42.8% +- 2.5%) and the dexmedetomidine-treated rats (43.2% +- 2.7%). Dexmedetomidine 47-62 CCAAT/enhancer binding protein zeta Rattus norvegicus 28-32 21596884-16 2011 CONCLUSIONS: Our data showed that in normovolemia, dexmedetomidine produced a proportionate decrease of rCBF and O(2) consumption. Dexmedetomidine 51-66 CCAAT/enhancer binding protein zeta Rattus norvegicus 104-108 21596884-18 2011 Dexmedetomidine prevented rCBF and O(2) consumption from decreasing after hemorrhage.
