Objective To understand the occupational exposure among medical laboratorians in a hospital,and put forward prevention and control measures.Methods Occupational exposure among medical laboratorians in the department of laboratory medicine of a hospital from January 2011 to December 2014 were analyzed statistically.Results A total of 72 cases of occupational exposure occurred among 217 laboratorians during 4 years,occupational exposure rate was 33.18％,the occupational exposure rate in interns was 46.23％,and in laboratorians with working seniority＜ 1 years was 49.56％.Occupational exposure mainly occurred in outpatient blood collection room(accounting for 38.89 ％),the main occupational exposure types were injuries by blood collection needles,skin contaminated by blood and body fluid(76.39 ％).Occupational exposure rates in medical laboratorians in this hospital during 2011-2014 were 53.66％(22/41),41.67％(20/48),26.23％(16/61),and 20.90％(14/67),respectively,which presented a declining tendency(x2 =12.286,P＜0.01).After occupational exposure,only 23 cases were reported according to the requirements of infection management department,the missing report rate was 68.06％ (49/72),correct handling rate was 80.56％ (58/72).Conclusion Laboratorians should strengthen education and training of healthcare-associated infection management,improve safety and prevention consciousness,standardize handling process,improve consciousness of reporting,so as to reduce the occurrence of occupational exposure and post exposure infection.

Objective:To explore the application effect of continuous nursing with Wechat as medium in patients with chronic heart failure.Methods:Using the convenient sampling method, a total of 102 patients with chronic heart failure who were treated in Zhejiang Hospital were selected as the research objects from June 2019 to June 2020. According to random number table method, they were divided into the observation group ( n=52) and the control group ( n=50) . The control group was given routine nursing intervention, while the observation group was given continuous nursing intervention with Wechat as medium. The effect of intervention was evaluated by Self-rating Anxiety Scale (SAS) , Self-rating Depression Scale (SDS) , Exercise of Self-Care Agency Scale (ESCA) and 36-item Short-Form (SF-36) . Results:There were no statistically significant differences in the scores of SAS, SDS, dimensions of ESCA and dimensions of SF-36 between the two groups at admission ( P>0.05) . Three months after intervention, SAS and SDS scores of patients in the observation group were lower than those in the control group, and scores of dimensions of ESCA and SF-36 were higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The continuous nursing with Wechat as medium has good application effect in patients with chronic heart failure, which can reduce the psychological mood of patients, improve the self-care ability and improve quality of life.

Objective:To explore the application value of scenario simulation teaching combined with two-way evaluation in standardized training of pediatric nursing.Methods:A total of 34 trainees who received standardized training of pediatric nursing in The First Affiliated Hospital of Air Force Medical University from March 2018 to March 2019 were selected as the control group, and another 42 trainees from April 2019 to July 2020 were selected as the study group. The control group used traditional teaching, and the study group used scenario simulation teaching combined with two-way evaluation. Theoretical examination and scenario simulation exercise examination were used to assess the theoretical knowledge and clinical practice ability of the trainees, and questionnaire survey was used to evaluate the satisfaction of the trainees with the teaching effect. SPSS 22.0 was used for t-test. Results:The scores of theoretical examination[(95.12±6.24) vs. (91.05±5.12)] and scenario simulation exercise examination (nursing practice skill operation ability, ability to combine theory and practice, clinical thinking and judgment ability, emergency handling ability, communication ability, humanistic care and professional learning ability, and work attitude) of the trainees in the study group were higher than those in the control group, and the differences were statistically significant ( P<0.05). The satisfaction evaluation of the trainees in the study group with the teaching effect was higher than that in the control group, and the difference was statistically significant ( P<0.001). Conclusion:Scenario simulation teaching combined with two-way evaluation can improve the theoretical knowledge, clinical practice ability, and teaching satisfaction of pediatric nursing trainees.
