Objective To evaluate the role of standard CPR training in Beijing Olympics medical volunteers by compared with the no-traimng medical personnel.Method Performance qualities of CPR was evaluated in the 44 medical vohmteers,who worked in a Beijing Olympic Venue.They received the training On standard CPR for 6 monthes,and served as training group.The performance of another 72 emergency medical workers from first-class hospitals without the training on stand CPR within 1 year(control group) Was compared with training group.Phillips QCPR3535 monitor was used to measure the compression frequency,depth and chest re-expand between the compression and the operation time via the sternal chest compression pad fitted with an accelerometer.Personal practical results of 5 circles of CPR operation were recorded in a table and the numbers ofpractical. Compression in one minute were counted.Data Were analyzed with chi-quare test and t-test.The parameters ofthe influence fac.tor(gender,age,hand placement,hand skill,compression posture and standard training)were brought into logistic regression analysis.Results Compared with the control group,the qualification rate of general CPR performance in the training group was much higher(86.4%vs.31.9%),and the compression cpmlification rates of the chestcompression,depth and chest re-palld betweenthe compression wcfe higher(88.6%,93.2%,95.5% vs.40.3%,43.0%,86.1%,P<0.01),the duration of ventilation in each operationstion was shorter[(6.38±1.3)vs.(7.57±1.6),P0.05],pratieal compressionn flberin oneminutewas not different[(77.2±3.5)vs.(77.8±12.2),P>0.05)],the ratios of the duration of compression to that of ventilation was higher(2.6:1 vs.2.1:1).Logistic analysis showed that hand skill,compression posture and standard CPR trainings were high correlated with the CPR performance qualities(P<0.05).Conclusions The performance quahty of training group is much higher thanthat ofcontrol group.The standard and continuous CPR training is elfecfive in improving the quality of CPR operation.

OBJECTIVE To investigate the bacterial distribution and sensitivity to antibiotics isolated from infected patients in emergency department. METHODS The antimicrobial susceptibility tests to commonly used antibiotics were performed to the specimen send by the emergency and respiratory departments in our hospital in 2007.The data were analyzed respectively. RESULTS Totally 340 strains were isolated in emergency department and 366 strains were isolated in respiratory department.The main bacteria isolated were similar in the two departments such as Acinetobacter baumannii,Pseudomonas aeruginosa,Staphylococcus aureus and Escherichia coli,but their sensitivities to antibiotics were different. CONCLUSIONS Bacterial distribution of the infected patients in emergency department is similar to respiratory departments,but their sensitivities to antibiotics are different.
