ABSTRACT
Objective To investigate the agitation effect of dexmedetomidine in the operation of radical hysterectomy by general anesthesia in patients.Methods 68 cases in this study who were under the operation of radical hysterectomy by general anesthesia in our hospital were selected, and randomly divided into the group A and the group B, 34 cases in each group.Group A received dexmedetomidine after tracheal intubation, and group B received physiological saline as the measurement of group A, hemodynamic and inflammatory factors were measured at different time points in anesthesia, the corresponding indexes and the degree of emergence delirium were compared.Results Compared with T1 , levels of HR and MAP increased, levels of SpO2 decreased at T3 and T4 in group B, levels of CRP, TNF-αincreased at T2 , T3 , T4 , T5 in group B, levels of CRP, TNF-αincreased at T3 , T4 , T5 in group A(P<0.05), and compared with the group A, levels of HR and MAP were higher at T3 and T4, levels of SpO2 were lower,levels of CRP, TNF-αwere higher at T2, T3, T4, T5in group B(P<0.05).The cough response score and agitation score in group B were higher than group A, and sedation score was lower than group A ( P <0.05 ) , the grade of emergence delirium in group A was better than group B ( P <0.05 ) . Conclusion Dexmedetomidine in the operation of radical hysterectomy by general anesthesia could reduce the emergence of agitation occurred, inhibit extubation reaction, but would not extend the anesthesia recovery time.
