ABSTRACT
Objective To explore a reasonable and secure anesthesia induction in painless induced abortion.Methods 120 patients of painless induced abortion were randomly divided into six groups,control group was injected with Propofol 3.5mg/kg through vein,besides given Propofol 3.5mg/kg,other 5 groups were injected with ketamine 0.1mg/kg、0.2mg/kg、0.3mg/kg、0.4mg/kg、0.5mg/kg through vein respectively.The parameter of hemodynamics,effect of analgesia,time of unconsciousness,recovery time of consciousness,recovery time of orientation,incidence of respiratory depression,side effect,time of discharge from hospital were observed.Results The recorded time and incidence of side effect have statistical significance between group of ketamine 0.5mg/kg and group of ketamine 0.3mg/ks(P<0.05);effect of analgesia have statistical significance between group of ketamine 0.3mg/kg、0.4mg/kg、0.5mg/kg and control group.Conclusion Ketamine 0.3mg/kg combined with Propofol is an ideal choice of painless induced abortion.
