目的 探讨情绪释放技术在老年白内障日间手术患者中的应用,评价其减轻患者术前焦虑情绪、降低术前紧张性高血压发生率的效果。方法 通过便利抽样法,选取2021年09月-12月于本院手术室接受白内障日间手术的老年患者216例,采用历史对照研究,将2021年09-10月符合纳入标准的108例白内障日间手术患者作为对照组,2021年11-12月的108例白内障日间手术患者作为实验组,对照组采取常规的护理干预措施,实验组在常规护理干预的基础上联合情绪释放技术的护理方案进行干预。比较两组患者的焦虑评分、血压、患者满意度。结果 实验组患者焦虑评分、血压降低幅度均低于对照组,差异有统计学意义(P<0.05)。实验组患者家属满意度高于对照组,差异有统计学意义(P<0.05)。结论 情绪释放技术可以有效地降低术前紧张性高血压的发生率,缓解白内障老年患者的焦虑情绪,降低手术取消率,提高患者的满意度,提升护理服务质量,为手术的顺利进行提供保障。  相似文献

AimThe current study sought to assess the perceptions of eHealth technology of nurses and nursing students in China and to examine the association between these perceptions and demographic factors.BackgroundDespite the increasing use of eHealth technologies in China and across the globe, the perceptions of practicing and student nurses remain minimally explored. Findings from such an inquiry can potentially inform actions and policies to improve the uptake of eHealth technologies among Chinese nurses.DesignThis was a cross-sectional study with a real-time online survey.MethodsA convenience sample of 1338 nurses and nursing students from Mainland China participated in the study. Their perceptions of eHealth technology were collected using the Chinese version of the Perceptions of eHealth Technology Scale. The Kruskal-Wallis test and multiple linear regression analysis were used to examine the relationship between demographic variables (age group, gender, occupation, education level, position and clinical experience) and perceptions of eHealth technology. All study procedures adhered to the STROBE guidelines.ResultsMost participants were aged between 20 and 29 (55.8%). Nearly half (42.5%) were frontline clinical nursing staff, some were nursing students (36.2%), academic nursing staff (12.3%) and clinical nursing management staff (9.0%). Regardless of the differences in their demographic characteristics, the participants had higher mean scores in “Perception of eHealth applications” and lower mean scores in “Knowledge of eHealth technology”. Participants with doctoral degree had a higher mean total score and higher sub-scale scores in knowledge of eHealth technology, perception of the advantages of eHealth technology and perception of eHealth applications; and the lowest scores in perception of the disadvantages of eHealth technology and perception of eHealth applications. Occupation, position and clinical experience were found to be the demographic characteristics associated with eHealth perceptions, before adjusting for age and gender. Education level was associated with eHealth perceptions regardless of adjustment.ConclusionOverall, participants had higher scores on perceptions of eHealth applications but lower scores on knowledge of eHealth technology. Considering the association between education and all subscales and overall scores, it may be essential to implement continuing professional education for nurses to improve their knowledge of eHealth applications. Encouragement to use available eHealth digital technologies may also be helpful to improve perceptions of eHealth.  相似文献

Teachers for the twenty‐first century for the global world need to be proficient in technology and skilled as reflective practitioners. They need to be able to reflect on diversity in myriad ways: learning styles, special needs, cultural differences, racial differences, developmentally appropriate differences, teaching styles and personality differences of children, teachers, parents, community members and administrators. The paradigni shift of the twenty‐first century is that teachers need to be team players who are skilled at operating in a variety of collaborative partnerships.

The Early Childhood Program Faculty, at NEIU, with the help of a Teacher Quality Education grant, developed with six universities in Illinois called Illinois Professionals Learning Partnerships (IPLP), set out to adapt the NEIU/ECED program for the twenty‐first century in a global world by focusing on four goals: (1) increasing technology and writing skills across the curriculum, (2) developing reflective skills and understanding of diversity (special needs, multicultural/international cultures), (3) developing student experience working in collaborative partnerships and (4) increasing clinical experiences.

The IPLP grant enabled the ECED program to: (1) spend intensive time on changing the curriculum in two retreats a year, (2) develop a faculty cohort including tenure track faculty, visiting lecturers and adjuncts, (3) develop a combined program of research and program development, (4) recruit and hire three new tenure track international faculty, (5) develop professional development schools and intensive field experiences, (6) combine resources for many grants, (7) develop short‐term international experiences and faculty exchange programs and (8) increase technology skills of students and faculty through action laboratories on using video technology, digital cameras, reflective email discussions and videography.  相似文献
