Objective Three common positions have been observed for its influence on the objective indicators of the patients with unilateral lung disease,and the change of subjective symptoms in these patients were collected.Methods The study group consisted of 93 patients who had unilateral lung diseases,each of which was randomly observed for three common positions (healthy side position,affected side position and the horizontal position) for 30 minutes respectively.In these patients,the changes of the objective indictors (heart rate,breathing,blood oxygen saturation,the mean arterial pressure) and subjective symptoms (chest stuffiness,breath is aggravating,etc.) were recorded.Results When using different positions,no statistical difference was observed with the heart rate,breathing,oxygen saturation and mean arterial pressure,whereas when affected side position was taken,the occurrence of worrisome symptoms was obviously higher than the condition when using healthy side position and the horizontal position.There was no statistical difference between the two groups of healthy side position and the horizontal position.Conclusions The occurrence of worrisome symptoms in the case of affected side po-sition is significantly more than the other two positions,indicating that patients with unilateral pulmonary disease are more willing to adopt the healthy side position and the horizontal position.

This article reviews the current status of the second victim related support in patient safety incidents at home and abroad, proposes the necessity of constructing a second victim support system, and summarizes the research progress on the second victim support assessment tools and systems abroad, with a view to provide references for the establishment of a multi-disciplinary second victim support system in China.

Objective:To evaluate the teaching effect of Emergency Nursing practice course using scenario simulation teaching combined with formative assessment. Methods:The subjects were selected from vocational nursing students of Batch 2015 (control group, n=49) and Batch 2016 (intervention group, n=40). The control group adopted the scenario simulation teaching method, and the intervention group added formative assessment on the basis of simulation teaching. The end-of-term theoretical scores of Emergency Nursing and the scores of students' general self-efficacy scale were used as evaluation tools. SPSS 22.0 statistical software was used for data processing and analysis. Results:The scores of the intervention group (85.20±8.05) were higher than those of the control group (79.73±8.46), with statistical significance ( P<0.05). The scores of self-efficacy in both groups were improved, while the scores of the control group after the course (2.68±0.42) were higher than those before the course (2.61±0.47), but there was no statistical significance. The scores of the intervention group after the course (2.78±0.43) were higher than those before the course (2.62±0.43), with statistical significance. Conclusion:The application of scenario simulation teaching combined with formative assessment in the practical course of Emergency Nursing can be helpful to improve students' self-efficacy and comprehensive ability of first aid.

Objective:To study the related factors of pressure ulcer in liver transplantation patients, to understand the occurrence of postoperative pressure sores in liver transplantation patients, and to propose corresponding nursing strategies to provide theoretical basis for clinical nursing work.Methods:A total of 93 patients with liver transplantation were investigated for postoperative pressure ulcers using a general data sheet and a Braden risk assessment form.Results:The Braden risk score of liver transplantation patients was significantly positively correlated with pressure ulcers ( t value was -3.512, P<0.01). Among the risk factors affecting patients with surgical pressure sores, low pressure ulcer score, postoperative hypotension and low serum albumin were pressure ulcers. The risk factors, OR value were 1.185 (1.037-1.354), 9.443 (2.273-39.237), 1.325 (1.119-1.570), and the short operation time was the protective factor of pressure ulcer. The OR value was 0.729 (0.542-0.981). Conclusions:Clinical medical staff should take comprehensive measures to treat patients with liver transplantation in different situations, reduce the incidence of pressure ulcers and improve the quality of life of patients.

? This paper reviews the application of WeChat in continuous care for patients with coronary heart disease (CHD), namely the WeChat group-based intervention, the WeChat public platform-based intervention, the combination of WeChat group and WeChat public platform, and the combination of WeChat group and other information technologies. In addition, this paper analyzes the effect of WeChat intervention, that is, its impact on disease knowledge, self-management behavior, quality of life and the occurrence of adverse cardiac events in patients with CHD, in order to provide a reference for enriching continuous care for patients with CHD, so that continuous care can be effectively combined with WeChat information technology.

Objective:To analyze the research status,research hot topics and trends in the field of domestic medical device disinfection supply,and to provide reference for clinical practice and scientific research of disinfection supply.Methods:Literature related to disinfection supply included in CNKI database from January 1,2008 to December 31,2023 were searched.CiteSpace visualization software was used to perform keyword co-occurrence analysis,cluster analysis,and emergence analysis.Results:A preliminary search of 1 527 articles was obtained,and 1,499 valid articles were finally included in the study,including 87 in 2008,and the number of publications related to disinfection supply increased year by year,reaching a peak of 258 articles in 2012,and gradually decreased and stabilized since then.A total of 12 keyword cluster tags were formed in 1 499 articles,and the three keywords with the highest frequency were cleaning quality,nosocomial infection and management.The implant keyword appeared in 2019 and lasted until 2023,which can be studied in depth as a potential research topic.Conclusion:Cleaning quality,nosocomial infection and management were the focus of researchers in the field of disinfection supply from 2008 to 2023,and the research direction has gradually developed from management research around industry standards to refinement,specialization and technology,and has become a research trend in the future.
