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.
ABSTRACT
Objective To evaluate the value of serum kaliuretic peptide (KP) in predicting atrial fibrillation (AF) and its prognosis,by detecting serum KP levels in patients with severe sepsis.Methods Fifty-six patients with severe sepsis in Integrated Intensive Care Unit of Shajing Hospital of Shenzhen Affiliated to Guangzhou Medical University from January 2014 to August 2015 were collected as the case group.In addition 20 cases health checkup for the same period were collected as the control group.Serum KP were determined in all patients in the case group every day for 1 week after admission,meanwhile the APACHE-Ⅱ score was undertook,then according to heart guardianship and electrocardiogram whether occurrence of AF the case group were divided into AF group and non AF group.According to survival after 28 days again divided into survival group and death group,the relationship of serum KP with AF and the prognosis were analyzed.Serum KP was detected on the day of physical examination in the control group.Results (1) The incidence of AF was 32.1％(18/56) in 56 patients with severe sepsis.(2)Serum KP in admission to hospital in case group was significantly higher than that in the control group((234.2±73.5) pmol/L vs.(169.6±65.4) pmol/L;t =3.47,P =0.001).Serum KP in admission to hospital in AF group was significandy higher than that in the non AF group((306.0±35.6) pmol/L vs.(200.2±61.2) pmol/L;t =6.79,P =0.001).Serum KP in AF group before 1 day of the occurrence AF was significantly higher than of the admission to hospital ((339.2± 30.5) pmol/L vs.(306.0±35.6) pmol/L;P=0.007),serum KP on the day of occurrence AF was significantly higher than before 1 days of the occurrence AF((390.6±47.8) pmol/L vs.(339.2±30.5) pmol/L;P=0.006),there was no difference between the serum KP after 1 days of occurrence AF and on the day of occurrence AF(P=0.246),but began to gradually declining.Serum KP and APACHE-Ⅱ score in death group on admission to hospital were significantly higher than survival group((301.1±42.0) pmol/L vs.(199.8±61.5) pmol/L,(26.1±2.8) points vs.(19.9±4.3) points;t =6.44,5.67;P＜0.001).(3) Linear correlation analysis showed that serum KP on admission to hospital was positively correlated with the occurrence of AF(r=0.679,P=0.010).According to AF grouping,serum levels of KP on admission to hospital draw ROC curve,the serum KP of AUC was 0.908(95％ CI:0.831-0.984),when the KP value was 351.5 pmol/L,the sensitivity of the occurrence AF was 89.9％,specificity of 97.4％.(4)Linear correlation analysis showed that serum KP on admission to hospital was positively correlated with death(r=0.659,P =0.010),according to prognostic grouping,serum KP on admission to hospital and APACHE-Ⅱ score ROC curve was drew,the serum KP of AUC was 0.893 (95％ CI:0.811-0.974),when the KP value was 338.5 pmol/L,the sensitivity of death was 78.9％,specificity of 97.3％.Conclusion Early serum KP level can be used as an indicator to predict AF and prognosis in the patients with severe sepsis.
