Objective To research the association between the prognosis of Acinetobacter baumannii infection and drug resistance among patients in the intensive care unit( ICU). Methods Eighty-four patients with Acine tobacter baumannii infection from February 2003 to April 2009 in Peking University Shenzhen Hospital ICU were retrospectively analyzed and divided into alive group(59 patients) and dead group(25 patients) by using 30-day mortality. The impact of drug resistant Acinetobacter baumannii on mortality was assessed by binary logistic regression. Results The mortality of patients with Acinetobacter baumannii infection was related to age, haematological malignancy, the Chanson Comorbidity Index, APACHEII score, multidrug-resistant Acinetobacter baumannii ( MDRAB) , carbapenem-resistant Acinetobacter baumannii (CRAB ) , septic shock and antimicrobial inappropriate therapy by univariate analysis( P < 0.05). Binary logistic regression revealed that CRAB( OR = 3. 360,95%CI: 1. 563 ～7.223,P< 0.05)and the Charison Comorbidity Index( OR = 1. 633,95% CI: 1. 201 ～2. 221 ,P <0.05) were independent risk factors. Conclusions The prognosis of Acinetobacter baumannii infection was closely correlated with drug resistance. The patients with CRAB infection had a higher mortality.

Objective To assess antibiotic prescription habits,cost pattern and the prospective intervention in Intensive Care Unit was analyzed.Methods Data on antibiotic utilization and antibiotics susceptibility were col-lected prospectively from individual electronic charts from July 2014 to September 2014.Results 225 of 246 patients surveyed used antimicrobial during the ICU stay,and antibacterial drug utilization rate was 91.46%.Cefperazone-sulbactam and piperacillin-tazobactam were the most prescribed medications.Total defined daily dose ( DDDs) was 1121.1 DDDs.Bacteria culture was 98 positive in 677 cases and 101 pathogenic bacteria were isolated.Conclusion Interventional programs should focus on promoting infectious control with rational antibiotic prescription aimed at mini-mizing the future emergence of bacterial resistance and futile.

Objective To evaluate the effect of optimizing surgerical patients’handover procedures using tracking methodology.Methods Two hundred patients hospitalized between July 2011 and May 2012 were assigned in the control group,in which their handover was conduced conventionally.Another 200 patients between April 2012 to February 2012 were assigned in the observation group,where their handover was done by tracking methodology.The two groups were compared in terms of incidence of adverse events at handover,time for handover and satisfaction of medical staff.Result Compared with the control group,the study group showed significantly lower incidence of adverse events,shorter surgical handover time and higher satisfaction degree of medical staff(P<0.05).Conclusion The tracking methodology can help to optimize handover procedures and quality control management, reduce the incidence of adverse events and improve working efficiency.

Objective To investigate the perioperative management and video-assisted thoraco-scopic (VATS) extended thymectomy for myasthenia gravis ( MG ). Methods A total of 102 patients who received extended thymectomy for MG from June 2000 to August 2007 were divided into 2 groups by operative approach: 51 in the VATS group and 51 in the full median sternotomy group. The clinical features, including operation time, operation blood loss, post-operative drainage, inci-dence of crisis, hospital stay, and the 1-year total effective rate after the operation were compared. Complications were treated exactly and cholinesterase inhibitors were applied to control the symptom of MG before the operation. The whole thoracic gland and fat in the anterior mediastinum were removed. Steroid, cholinesterase inhibitors and plasmapheresis were used to prevent and cure masthemic crisis after the operation. Results No patients died in the operation and hospitalization. There was no sig-nificant difference in the operation time [(128.14±34.82) min vs. (130.46±28.71) min] and the 1-year total effective rate after the operation (85.8% vs. 87.2% )in the 2 groups(P>0.05).The operation blood loss, postoperative drainage, incidence of crisis, and postoperative hospital stay in the median sternotomy group were higher or longer than those in the VATS group [(93.77±21.64) mL vs. (45.42±10.96)mL,P<0.05; (174.65±21.64)mL vs. (101.33±28.76) mL,P <0.01;7.84% vs. 1.96%, P<0.05;(14.23±3.17)d vs. (8.37±1.18)d, P<0.05)]. Conclusion VATS extended thymectomy for myasthenia gravis is safe, less invasive and effective. Preoperative preparation and the perioperative managemant can decrease the incidence of crisis. The plasmapheresis is the key of curing masthemic crisis.

Objective To establish a simple,rapid,accurate and practical method for determination of chloride in drinking water by chloride ion-selective electrode.Methods The chlorine ion-selective electrode was used as indicator electrode and type217saturated calomel electrode of the double salt bridge(the lower salt bridge was filled with a solution of0.1mol/L potassium nitrate)was used as reference electrode.The contents of chloride in water were calculated using the calibration curve method in the electrolyte containing0.1mol/L potassium nitrate.Results The linear range of the method was10 -5 -10 0 mol/L and the best lin ear range was10 -4 -10 -1 mol/L with r=0.9999and the slope=53.5?0.667.The detection limit,recovery rate and coefficient of variation(CV)were0.3545mg /L,94.2%-102.2%(mean98.1%)and2.8%respectively.The suitable pH for the determination of the method was2-10.In the solution containing3.545mg/L chloride,50times more BrO -3 ,NO -2 ,CH 3 COO - ,SO 42- ,F - ,CrO 42- and10times more CO 32- could not interfere with the detection,but Br - and I - were interfering factors.The re-sults obtained by the chlorine ion-selective electrode method and the national standard determination method showed no statistic differences.Conclusion The method was easy to operate,rapid,accurate and suitable for determination of chloride in water.
