[Abstract]? Objective? To construct a theoretical knowledge system for stroke emergency nurses and to provide reference for the establishment of the theoretical knowledge training course for stroke emergency nurses. Methods? Through literature review and referring to relevant guidelines, the preliminary items of theoretical knowledge of stroke emergency nurses were formed. Through Delphi method, 20 experts were inquired for two rounds, and the main points of theoretical knowledge were established. Results? The positive coefficients of the two rounds of expert inquiries were 100%, and the positive coefficients of experts were high. The judgment basis, familiarity and authority coefficients of expert consultation were 0.925, 0.844 and 0.885, respectively, all＞ 0.700, and the reliability of consultation results was high. The Kendall Harmony Coefficient of the secondary indicators was 0.462 and 0.293 respectively (P＜0.01). The theoretical knowledge system of stroke emergency nurses included 8 primary indicators, 24 secondary indicators and 45 key points of knowledge. Conclusions? The consultation experts' opinions are concentrated and the results are credible. The establishment of the theoretical knowledge system of the stroke emergency nurses can provide a reference for setting up the theoretical training courses for stroke emergency nurses.

Objective:To explore the relationship between personality characteristics, social psychology and satisfactory rate in people undergoing facial cosmetic surgery.Methods:People undergoing facial cosmetic surgery who were admitted to the First Affiliated Hospital of Naval Medical University from February 2021 to February 2022 were seclected. They were asked to fill out the Big Five Inventory (abbreviated version), social psychological factors questionnaire before surgery, and the surgical satisfaction scale 2 weeks after surgery. According to the results of surgical satisfaction, they were divided into satisfied group and dissatisfied group. The distribution of personality characteristics and social psychological factors was analyzed, univariate analysis and logistic multiple regression were used to analyze the personality characteristics and social psychological factors affecting the satisfaction result.Results:There were 217 cases, including 9 males and 208 females, aged 18-45 years old with an average age of 26 years old. According to the operation satisfaction survey, 174 cases were satisfied and 43 cases were dissatisfied. Among the personality characteristics of 217 cases, low agreeableness, high responsibility, high extraversion, low openness, and high neuroticism accounted for the majority; there were statistically significant differences in agreeableness, extraversion, openness, and neuroticism between the satisfied group and the dissatisfied group( P<0.05); but in the comparison of responsibility, there was no statistically significant difference between the two groups ( P>0.05). Among the psychosocial factors of 217 cases, female, aged 18-28 years, with a bachelor’s degree or above, a vocational student or employee, urban registered residence, with a medium income, with a history of plastic surgery, following the doctor’s advice, moderate expectation, surgery suggestion with family members account for the majority; the results of univariate analysis show that the satisfied group and the dissatisfied group were compared in terms of age, education level, monthly income, surgical cost, previous plastic surgery history, and expected effect, the difference was statistically significant ( P<0.05); however, there was no statistically significant difference in gender, marital status, occupation, nature of household registration, choice of surgery, surgery recommended by family members, and consultation in multiple hospitals ( P>0.05). The results of logistic regression analysis showed that low agreeableness, low extraversion, high neuroticism, low age, high education level, and high expectation were independent risk factors affecting the surgical satisfaction( P<0.05). Conclusion:Personality characteristics (low agreeableness, low extraversion, high neuroticism) and social psychological factors (low age, high education level, high expectation) are independent risk factors of surgical satisfaction in people undergoing facial cosmetic surgery.

[Abstract]? Objective? To explore the position and responsibilities of stroke emergency specialist nurses. Methods? The interviewing method in qualitative studies was adopted and in-depth semi-structured interviews were conducted on four doctors, four nurses, two technicians and six managers. Claizzi's seven-step phenomenological data analysis method was used to encode, assemble, categorize, analyze and refine the content theme. Results? The position of stroke emergency specialist nurses is compound specialist and team coordinator. Its duties include accurate identification of stroke patients, early warning for CT room and rapid preparation before thrombolysis, assisting family members in clinical decision-making, ensuring seamless connection of all steps, handing over with rescue room and digital subtraction angiography (DSA) room and ward, ensuring adequate material supply, establishing and maintaining database and continuing patient return visit. Conclusions? The post setting of stroke emergency specialist nurses laid a foundation for the rapid treatment of stroke patients. Their role was positioned as senior practical nurses, and their post setting faced a series of challenges. Promoting the mature experience of post setting of stroke emergency specialist nursess can train a group of stroke emergency specialist nursess and lead the development of specialized stroke nursing.

Objective: To investigate the application effect of Power port in contrast-enhanced CT scans. Methods: Totally 220 cancer patients who needed contrast-enhanced CT scans after chemotherapy were selected in Changhai hospital From September 2017 to September 2018, including 110 cases in the observation group and 110 cases in the control group with convenient sampling method.The observation group was injected contrast medium through Power port for CT scans. Contrast medium was injected into the control group by 22G of Peripheral venous access devices (Introcan®). The incidence of contrast medium exosmosis, nursing time and patient satisfaction were compared between the two groups. Results: The incidence of extravasation of contrast medium in the observation group was 0, lower than that in the control group 9.1% (10/110), the difference was significant(χ²=10.476,P=0.015); the nursing time in the observation group was (2.60 ±0.15) minutes per time, which was lower than that in the control group (5.60 ± 5.29) minutes per time), the difference was significant (t=5.934, P=0.000); the patient satisfaction in the observation group was higher than that in the control group, the difference was statistically significant (Z=-12.695, P=0.000). Conclusions Contrast medium injection through Power port for CT scans can reduce the incidence of contrast medium exosmosis, reduce nursing hours and improve patient satisfaction.
