Objective To investigate the difference of restlessness of patients who was in the stage of recovery from general anesthesia when using urethral catheterization in different time. Methods Divided 80 patients with carcinoma of esophagus into 2 groups randomly.For the cases in the experimental group,using urethral catheterization before the general anesthesia,while for the cases in the control group,using urethral catheterization after the general anesthesia.Compare the condition of restlessness and the ratio of canal emerge of 2 groups. Results The condition of restlessness and the ratio of canal emerge in the experimental group were both better than those of in the control group,P

Objective: To investigate the combined examination of plasma levels of troponin T (TnT) and N-terminal pro-brain natriuretic peptide (NT-proBNP) for predicting the risk of peri-operative cardiovascular events in elder coronary artery disease (CAD) patients with non-cardiac surgery. Methods: A total of 200 patients from (60-82) years of age with elective non-cardiac surgery were enrolled. The patients were divided into 2 groups: CAD group,n=118 and Non-CAD group,n=82. Plasma levels of TnT and NT-proBNP were examined at 1 day before and 2 days after the operation respectively. The cardiovascular events were recorded in both groups and the best cut-off values for TnT and NT-proBNP in risk prediction were evaluated by receiver operating characteristic (ROC) analysis. Results:①CAD group had the higher levels of post-operative TnT and NT-proBNP than pre-operative; both TnT and NT-proBNP levels were higher in CAD group than those in Non-CAD group at the same time points, allP<0.05.②The total cardiovascular events in CAD group was higher than those in non-CAD group (χ2=5.85,P=0.016) and the individual event was similar between 2 groups.③In CAD group, the best cut-off value for pre-operative TnT in predicting peri-operative cardiovascular events was 18.5 ng/L with the sensitivity at 72% and speciifcity at 69.6%; for NT-proBNP was 98.0 pg/ml with the sensitivity at 90.8% and speciifcity at 74.6%.④The patients with the higher level of pre-operative TnT had the increased risk of total cardiovascular events than those with normal TnT (χ2=4.56,P=0.043), and the same as NT-proBNP (χ2=4.08, P=0.036). Likewise, the patients with higher levels of both pre-operative TnT and NT-proBNP had the increased risk of total cardiovascular events than those with normal TnT and NT-proBNP (χ2=13.32,P=0.000). Conclusion:Either plasma levels of TnT or NT-proBNP could be used as the biomarker for predicting the risk of peri-operative cardiovascular events in elder CAD patients with non-cardiac surgery, the combined examination would have the better predictive value.
