Abstract: Objective: To observe and compare the influence of two different anesthesias on the homodynamic and awakening time of patients over 60 receiving thoracic surgery.Methods: Thirty ASA-Ⅱ status patients older than sixty undergoing thoracic surgery were randomly divided into two groups with 15 cases each,the general anesthesia group(GA group) and the epidural combined general anesthesid group(EGA group).The ECG,BP,and SpO₂ were measured constantly.The baseline values before anesthesia(T₁),(1 minute)(T₂)and 5 minutes(T₃) after incubation,1 minute(T₄)and 60 minutes(T₅) during operation,and extubation(T₆)were recorded.The awakening time was observed.Results: In GA group,HR did not have statistical difference compared to the baseline values before anesthesia(P>0.05).SBP increased significantly(P<0.05-P<0.01) at T₂,T₄ and T₆.In EGA group,HR,except at T₆,decreased significantly(P<0.05-P<0.01) compared to the baseline values before anesthesia,but SBP had no statistical difference compared to the baseline values(P>0.05).All values of HR,SBP,DBP at T₂-T₆ in GA group were higher than those in EGA group(P<0.05-P<0.01).The awakening time was shorter in EGA group than in GA group.Conclusions: Epidual-general anesthesia can maintain the homodynamic stability better and shorten the awakening time of the old patients undergoing thoracic surgery.
