Objective Observing the effect of general anesthesia (GA) with remifentanil on parturients undergoing cesarean section and Apgar score of child.Methods 40 parturients were divided into two groups,GA combined remifentanil (group A,n =20) and standard GA(group B,n =20).Observe the change of hemodynamics parameter and Apgar score of child.Results In group A than in group B maternal hemodynamic index smooth,two groups of intubation after lmin SBP,DBP,HR decreased,while the5 min after intubation returned to normal.SBP DBP,HR before induction,the difference between groups was not statistically significant (P＞ 0.05),the two group after induction,SBP,DBP,HR intubation after 1 min were (120.8 ± 19.6 mm Hg,80.6 ± 11.2 mm Hg,98.1 ± 17.1 BPM),(128.1 ± 17.5 mm Hg,98.9 ± 13.8mm Hg,108.7 ± 20.7 BPM) after intubation of 5 min were (98.3 ± 24.7 mm Hg 75.3 ± 13.8 mm Hg,79.9 ±22.6 BPM),(121.5 ± 16.2 mm Hg,88.6 ± 13.7 mm Hg,110.5 ± 17.4 BPM) had a significant difference (P ＜ 0.05),neonatal 1 min,5 min Apgar score,no significant differences between the two groups (P ＞0.05).Conclusion When remifentanil is used in the general anesthesia,its inducing is smoothly and it is no significant bad effect on the newborn.

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.
