Abstract:
Objective To investigate the effects of dexmedetomidine on hemodynamics and tra-cheal intubation facility in general anesthetized patients.Methods Forty gynecological patients of se-lective operation under general anesthesia were randomly arranged into 2 groups:group D and group C.With high flow mask oxygen inhalation(5 L/min),dexmedetomidine was intravenously pumped in-to the patients in group D at 0.6μg/kg in 10 minutes while in group C saline were given instead.Both groups were then proceeded with rapid sequence induction (RSI)immediately.The values of MAP, HR,PaO2 and PaCO2 were recorded every minute from pumping start till 15 minutes,the bucking, intubation time and glottis exposure were evaluated as well.Results No significant differences were found in intubation time or glottis exposure between these two groups.After tracheal intubation group D showed higher MAP value than group C at 14,15 minutes,and a lower HR value (P <0.05).Even no significant differences were found in values of SpO2 and PaO2 ,the group D showed less bucking than the group C (P<0.05).Conclusion Dexmedetomidine administration at 0.6μg/kg in RSI can diminish the variation in hemodynamics and facilitate the tracheal intubation by less buc-king,but no affect the oxygen reserve.
