ABSTRACT
Objective To investigate the effect of virtual simulation teaching method in the comprehensive experimental teaching.Methods In experimental teaching of nursing,simulation medical records were compiled,plans were implemented,experiment guidance materials were preliminarily formed and teaching effect was evaluated.Results The application of virtual simulation teaching in nursing comprehensive experiments reflected the comprehensiveness of teaching content,and the comprehensiveness of knowledge,ability and capacity.It could train students creative ability,exploring spirit,enhance the sense of professional and humane care consciousness,train the communication skills and strain capacity,make active teaching atmosphere,improve the quality of teaching.Conclusions This teaching method can make students achieve mastery through a comprehensive multi-disciplinary knowledge,improve the ability of solving practical problems,help nurses to develop the comprehensive professional quality.
ABSTRACT
Objective To investigate the risk factors and outcomes of acute kidney injury (AKI) in patients after intra--coronary stent implantation.Methods A retrospective and case control study was done with data analysis in 325 patients who underwent intra-coronary stent implantation from January 2010 to March 2011.The patients were divided into two groups as per the criteria of AKI identified on the 7th day after implantation of stent.The variables to be studied included:(1) age,gender,hypertension,diabetes,cerebrovascular disease,left ventricular insufficiency,peripheral angiopathy,creatinine,urea nitrogen,estimated glomerular filtration rate,hyperuricemia,proteinuria,emergency operation,hydration,and medication (ACEI/ARB,statins) before operation; (2) dose of contrast media,operation time,hypotension during intra-operative period; and (3) postoperative:hypotension.The variables were analyzed with the process of One-way ANOVA and multivariate Logistical regression analysis.Consequently,the independent risk factors of AKI in patients after intra-coronary stent implantation could be found.Further,the prognosis of AKI patients was analyzed.Results Of the 325 patients,51 (15.7％) developed AKI.Compared the normal group,hospital stay (P ＜ 0.01 ) and in-hospital mortality (P ＜ 0.05) increased significantly in the AKI group.Monofactorial analysis showed that age,pre-operative laboratory and clinical data including left ventricular insufficiency,peripheral angiopathy,creatinine,urea nitrogen,estimated glomerular filtration rate, hyperuricemia, proteinuria, hydration and emergency operation, and intraoperative information such as operation time and hypotension,and postoperative hypotension in AKI patients group were significantly different in comparison with control group ( P ＜ 0.05 ). Multivariate logistic regression analysis revealed that elderly age (OR =0.253),pre-operative proteinuria (OR =5.351 ),preoperative left ventricular insufficiency ( OR =8.704),eGFR ≤ 60 ml/ ( min · 1.73 m2 ) ( OR =6.677 ),prolonged operation time ( OR =1.017),intra-operative hypotension ( OR =25.245 ) were independent risk factors of AKI ( P ＜ 0.05 ).Conclusions AKI is a common complication and associated with increase in mortality after intra-coronary stent implantation.Increase in age,pre-operative proteinuria,pre-operative left ventricular insufficiency,pre-operative low estimated glomerular filtration rate,prolonged operation time,intra-operative hypotension are the independently risk factors associated with AKI.
