背景：靈性存在於人內在的本質，對人展現關懷是一種靈性涵養的表現，而急診護理人員時刻參與著他人生命的離合，其決定關懷的靈性本質蘊涵，卻少有文獻了解與窺探。目的：以質性研究法，探討急診室護理人員靈性本質的內蘊。方法：採半結構式訪談指引，針對15位急診護理人員，進行一對一深度訪談收集資料，依據Tesch質性內容分析法進行分析。結果：本研究分析歸納出，急診護理人員靈性本質的蘊涵有三主軸：內心的力量（四個次主軸含真實存在的心靈力量、難以形容的抽象狀態、漣漪般地蔓延轉化、與撫慰人心的療癒力量）；非彼無我的價值與使命（兩個次主軸含善用能力不負使命，以及幫助他人豐富自我）；柔性韌力的淬鍊（三個次主軸含盡責更要盡善、情與理交織不定、以及抽離情感轉化心緒以面對現境）。結論：內在的靈性蘊涵是急診護理人員的力量來源。因此，學校與醫院職場護理教育，應加入內在察覺的靈性成長課程來飽滿護理人員靈性的蘊涵與力量。

Background: Spirituality is the essence of being human and the capacity to express caring for others. Emergency room (ER) nurses are required to deal regularly with patients in critical condition. Nourishing the spirituality of ER nurses is widely recognized as an important way to help nurses provide care to patients in clinics. However, few studies have explored the spiritual nature of ER nurses.Purpose: This study explored perceptions of spirituality among ER nurses.Methods: This study used a descriptive-qualitative design and purposive sampling; we recruited 15 ER nurses as participants and collected data using face-to-face, semi-structured interviews; Tesch's qualitative data analysis was employed to analyze data. Results: Nurse perceptions of spirituality were classified into 3 dimensions with 9 subthemes, namely (1) "an inner force" (with the 4 subthemes of real spiritual power, indescribable abstract state, change comes agonizingly slowly, and healing power), (2) "the value and mission of a jointly shaped one and the other" (with the 2 subthemes of making good use of one's ability and satisfying others to enrich oneself), and (3) "test of resilience" (with the 3 subthemes of being more responsible, interaction of sense and sensibility, and facing reality with reasons).Conclusions: This study introduced the idea of spirituality as an inner power as perceived by ER nurses. Findings may provide a basis for spiritual education in nursing schools and the workplace as well as suggest spiritual growth guidelines for nursing leaders and staffs.
