The Application of Continuing Vein Infusion of Propofol during Hysteromyoma Operation Performed with Radio Frequency Current Ablation

Objective To discuss the optimal speed of Propofol infusion by phleboclysis in hysteromyoma operation performed with radio frequency current ablation,and its effect on respiratory circulation.Methods 90 patients with hysteromyoma were randomly divided into group A,B and C,and each patient received continuing infusion of Propofol at the preliminary dose of 2.0 mg/kg.In the process of operation,the speed of Propofol infusion by phleboclysis for Group A,B and C were 7.5 mg/（kg·h）,8.0 mg/（kg·h） and 8.5 mg/（kg·h） respectively.Before anesthesia and during operation,the parameters of BP,HR,RR,SpO2,BIS were recorded by multifunctional physiological monitor.Results With continuing infusion of Propofol at the speed of 8.0 mg/（kg·h）,Group B obtained the best anesthesia result.In the whole process of operation,all the parameters of BP,HR,RR,SpO2,and BIS were within the normal range.When compared with group A,no patient was evaluated as grade Ⅲ of anesthesia effect in group B,and their vital signs were comparatively steady.When compared with that of group C,the anesthetics used in group B had less effect on cardiovascular and respiratory systems.Conclusion Continuing infusion of Propofol by phleboclysis at the speed of 8.0 mg/（kg·h） can achieve satisfactory anesthesia effect.
