Objective: To explore the psychological experience of patients with aortic dissection facing rescue of follow patients in CCU, so as to provide evidences for proposing appropriate nursing countermeasures and responding measures. Methods: A qualitative study was used on 16 patients with aortic dissection within 24 hours when the rescue of follow patients was in CCU through semi-structured in-depth interviews and the interview data were collected and analyzed by Colaizzi content analysis. Results: The enlargement of somatic discomfort symptoms. The various emotional. The different coping strategies. The inner needs. Conclusions When rescuing patients with other aortic dissection in CCU, medical staffs should pay more attention to the distress of physical discomfort symptoms such as pain, promote their benign mood during rescue and encourage patients to adopt positive coping styles. At the same time, constructing a reasonable social and family support ways to help patients recover physically and mentally, ensure the quality of nursing services and patient safety, and improve their hospitalization comfort.

Objective To explore the clinical teaching intervention measure and effect of the cultivation of humanistic quality of post 90s nursing students in practice .Methods One hundred and forty-eight nursing students in practice from 2012 and 152 cases from 2013 were chosen and divided into the control group and the observation group .The control group received traditional way of teaching , the observation group received the intervention study on the cultivation of humanistic quality about ten months through the bucket theory .The comprehensive intervention measures were carried out through the way of joint teaching in all clinical departments so as to improve the teaching philosophy , update the concepts of education , reform the curriculum structure, optimize teaching contents , refine teaching processes , and strengthen the model and guidance .The evaluation was carried out according to the formulation of methods and standard of evaluating the humanistic quality and professional image of nursing students in practice , and the scores of evaluation were analyzed , and the interventional effect was compared .Results The cases of nursing students in practice who respectively got 10-20, 21-30, and 31-40 were 4 cases (2.6%), 49 cases (32.3%), 99 cases (65.1%) in the observation group, and were significantly higher than 22 cases (14.9%), 53 cases (35.8%), 73 cases (49.3%) in the control group, and the difference was statistically significant (Z=-3.351, P<0.05).The score of hospital patients on the cultivation of humanistic quality and self-evaluation of nursing students in practice in the observation group were higher than those in the control group , and the difference was statistically significant (Z=-3.202, P <0.05 ).Conclusions The implementation of the intervention of the cultivation of humanistic quality through the bucket theory can effectively improve the nursing students ’ humanistic quality , improve the professional image , and is benefit to all-round development of the nursing students in practice .

Objective To explore the relationship between the disease uncertainty and information demand in preoperative patients with aortic dissection. Methods A total of 100 preoperative patients with aortic dissection were investigated from January 2012 to January 2014 with Mishel′s uncertainty in illness scale ( MUIS) , Hamilton anxiety scale ( HAMA) and self-designed information collection table, and the correlations were analysed. Results The total score of MUIS was (112. 32 ± 9. 66), and the number of patients in middle level was 90 (91. 8%). The score of ambiguity was (42. 32 ± 4. 54), and the number of patients in middle level was 85 (86. 7%). The score of complexity was (22. 43 ± 3. 63), and the number of patients in middle level was 68 (69. 4%). The score of lack of information was (19. 32 ± 2. 75), and the number of patients in middle level was 65 (66. 3%). The score of unpredictability was (15. 43 ± 2. 78), and the number of patients in middle level was 60 (61. 2%). The total score of HAMA was (13. 65 ± 11. 64), and the number of patients in middle level was 60 (61. 2%). The score of information requirements was (141. 34 ± 14. 56), and the number of patients in middle level was 65 (66. 3%). The score of disease and treatment was (62. 32 ± 4. 54), and the number of patients in middle level was 65 (66. 3%). The score of health was (32. 43 ± 3. 63), and the number of patients in middle level was 68 (69. 4%). The score of mental health was (17. 43 ± 2. 78), and the number of patients in middle level was 60 (61. 2%). The score of family health was (9. 64 ± 2. 65), and the number of patients in middle level was 65 (66. 3%). The score of social health was (7. 34 ± 2. 56), and the number of patients in middle level was 60 (61. 2%). The different dimensions of disease uncertainty were positively correlated to anxiety, treatment of disease, physical health, mental health, family health, social health and information demand (P<0. 05). Conclusions Preoperative patients with aortic dissection have the medium level of disease uncertainty and are affected by anxiety. They have a high level of demand for the disease and treatment information, and health information. The information demands significantly affect the patient′s disease uncertainty.

Objective To analyze risk factors of Swan-Ganz catheter-related bloodstream infections ( CRBSI) in patients with severe heart disease in Cardiac Care Unit ( CCU) . Methods A total of 768 patients undergoing indwelling Swan-Ganz catheterization in CCU between January 2013 to December 2014 were enrolled in this study. Bacterial culture of blood in catheter and catheter tip that 5 cm distance from distal end were performed if the patients were suspected of intravascular catheter-related infections or the catheter was removed from the patients for more than 7 days. Results During 3050 catheter days, 23 of 768 patients were diagnosed of CRBSI(7. 5 ‰), and the infection rate was about 3%. The top 5 pathogenic bacteria were staphylococcus aureus, staphylococcus haemolyticus, staphylococcus epidermidis, albicans saccharomyces and klebsiella pneumoniae. The patient′s gender, ages, with diabetes or not, and usage of antibiotic during catheterization had no correlation with catheter related infection (P >0. 05), but the skin of whole body clean or not before catheterization, the length of catheterization had correlation with catheter related infection ( P < 0. 05 ). Multivariate logistic regression analysis showed that the whole bode skin clean before catheterization was the protective factor for CRBSI, and long catheter indwelling time and combined antibiotic treatment during catheterization were the risk factors for CRBSI (P<0. 05). Conclusions The incidence of CRBSI in patients with severe heart disease is related to the catheter indwelling time, and skin clean before indwelling which are able to effectively reduce the incidence of CRBSI. Antibiotic treatment during catheterization is not beneficial for decreasing the incidence of CRBSI.
