Objective:To investigate the current status and correlation between perceived stress and coping strategies among nurses in the Cardiac Intensive Care Unit (CICU) .Methods:A purposive sampling method was used to select 348 CICU nurses from ten tertiary hospitals in Beijing between March and October 2023. Data were collected using a general information questionnaire, the Chinese version of the Perceived Stress Scale (PSS), and the Simplified Coping Style Questionnaire (SCSQ) .Results:The score of the Chinese PSS among 348 nurses was (28.86±5.06). In the SCSQ, the score for positive coping was (22.71±7.57), while the score for negative coping was (8.57±4.82). Correlation analysis indicated that perceived stress was negatively correlated with positive coping strategies ( P<0.01) and positively correlated with negative coping strategies ( P<0.01). Multiple linear regression analysis showed that years of experience in the CICU, employment status, family support for work, and coping strategies were influencing factors of perceived stress ( P<0.05), explaining 50.2% of the total variance. Conclusions:CICU nurses generally experience high levels of perceived stress, and those who tend to adopt negative coping strategies report even higher stress levels. Nursing administrators should develop targeted interventions based on nurse characteristics to promote effective coping strategies and alleviate perceived stress.

Objective:To explore the barrier factors of career development among nurses during career establishment period so as to provide a reference for promoting the professional development of nurses.Methods:From March to April 2019, we selected 10 nurses in the career establishment period of a GradeⅢ Class A hospital in Beijing by purposive sampling. The grounded theoretical method in qualitative research was used to carry out the face-to-face semi-structured interview and live recordings. The interview data were anonymously transcribed, coded step by step and subjects of them were extracted with the help of NVivo 11.0 qualitative analysis software.Results:Barrier factors of career development of nurses during career establishment period included three themes, namely, career development motivation changes (including career development willingness, career identity and family orientation) , work investment changes (including time investment and energy investment) and impacts of career development environment (including organizational support and team atmosphere) .Conclusions:Inadequate motivation for career development, insufficient work investment and poor nursing career environment are the barriers to the career development of nurses during career establishment period. This suggests that nursing managers can take work incentives from the perspective of positive psychology, create a good team atmosphere, fully excavate the career development motivation of nurses during the career establishment period, help nurses turn passive to active during career establishment and finally achieve career and family development.

Objective To explore whether perioperative bright light therapy could inhibit the occurrence of postoperative delirium in tumor patients undergoing open hepatobiliary surgery. Methods Totally120 elderly tumor patients scheduled for open hepatobiliary surgery and postoperative ICU treatment were recruited and randomized into bright light and control group with 60 cases per group in accordance with the random number table.Bright light was delivered to the patients at an intensity of 10 000 lux from 2 days before surgery to postoperative day 7.Each intervention began at 7 am and lasted for 2 hours.Delirium was screened using the Confusion Assessment Method for Intensive Care Unit(CAM-ICU) during the first 7 days after surgery. The differences in the incidence of postoperative delirium, the duration of delirium and the length of ICU as well as postoperative hospital stay were compared. Results Demographic characteristics and surgical outcomes were similar between groups. The incidence of postoperative delirium were 46.67%(28/60)and 23.33%(14/60)for control group and bright light group respectively with a significant difference (χ2=7.179,P=0.007). The difference was seen on postoperative days 3 (χ2=5.187, P = 0.023) and 4 (χ2=8.749,P = 0.003). The incidences of delirium on postoperative days 3 for bright light and control group were 5.08%(3/59)and 18.64%(11/59)respectively.On postoperative day 4, the incidences of delirium for bright light and control group were 0 (0/58) and 14.04% (8/57) respectively.There was no difference in the duration of delirium(χ2=1.248,P=0.264),the length of ICU stay (χ2=0.036,P=0.849)or the hospital stay(χ2=1.706,P=0.192). Conclusion Bright light is useful in preventing postoperative delirium in elderly tumor patients undergoing open hepatobiliary surgery.

Objective To know the influencing factors of nursing associations of different provinces and cities undertaking transferred government functions,and to explore the new direction of nursing management system reform based on the association platform.Method 10 experts from 9 provinces and cities were interviewed,and statistics was analyzed by three-level coding combining with QSR NVivo10.0 software.Result 3 themes were collected (internal factors,external support factors and others,such as an independent legal status,financial support,etc).Conclusion Nursing associations,as participants of medical organization and hospital management,must make their own capabilities clear,continuously strengthen their own ability in order to provide better service,and promote the development of medical and health career.

Objective To compare the cleaning effect of before and after improvement of P′750 type endoscopic infusion pump sensing infusion. Methods 240 cases of urinary calculi patients were divided into experimental group (120 cases) and control group (120 cases) according to the random number table method. Experimental group made improvements on P′750 type endoscopic infusion pump sensing infusion, Took latex transmission pipe, sampling module, metal fittings and parenteral nutrition infusion bags, disposable connecting pipe connection, and surgery using improved sensing infusion. The control group used unimproved sensing infusion. Results Visual inspection of cleaning pass rate before and after improvement sensing infusion were 85.83% (103/120), 99.17% (119/120), 5 times with light magnifier inspection were 78.33%(94/120), 97.50% (117/120), tampons method inspection were 75.83% (91/120), 95.83% (115/120), ATP bioluminescence monitoring were 70.83% (85/120), 91.67% (110/120), dry pass rate were 90.83%(109/120), 100.00% (120/120), cleaning and drying pass rate were significantly improved (χ2=18.296, 29.159, 32.986, 40.976, 11.528, all P<0.01). Cleaning time before and after improvement sensing infusion were (1 020.40±8.22) s, (539.30±8.70) s. Dry time were (1 199.35±26.70) s, (61.50±5.79) s. Cleaning and drying time were significantly shortened (t=440.340, 456.206, all P<0.01). Conclusion Improvement sensing infusion increased the quality of cleaning and drying, shortened the cleaning and drying time, ensured the quality of surgery using equipment, improved work efficiency, and provided a guarantee for the safe and smooth implementation of the surgery.
