Abstract:
Objective To observe the effect of Dexmedetomidine (DEX)on induction peri-od of hemodynamics in patients undergoing general anesthesia combined with epidural block.Meth-ods A total of 40 hysterectomy patients in optional period (ASA Ⅰ~Ⅱ)were randomly divided into Dexmedetomidine group(Group D)and Propofol group(P group).Group D received continuous epidural anesthesia with infusion of DEX 0.5 μg /(kg·h)and endotracheal intubation was applied after general anesthesia.Group P was given the same therapy with group D except dexmedetomi-dine.HR,SBP,DBP and MAP of the hemodynamic index were recorded at the time of entering the operation room(T1),after the determination of epidural plane(T2),pre-intubation(T3),intu-bation(T4),immediately after trachea intubation(T4),and the beginning of operation(T4).Results The difference was not statistically significant in the index between the two groups at T1 .HR of group D was lower than that in group P at all-time points(P <0.05).SBP,DBP and MAP of group D were higher than group P at T2,T3 and T4(P <0.05).SBP,DBP,MAP of group D were lower than group P at T5 and T6(P <0.05).SBP、DBP and MAP in group D at T2、T3 and T4 were higher than that in the group P (P <0.05).Conclusion Dexmedetomidine can offer a stable hemo-dynamics in the patients with general anesthesia combined with epidural block.
