本研究係以中台灣地區非創傷性到院前心跳停止(OHCA)之成人為對象，瞭解到院前心跳停止病人在到院前及到院後於不同變項中急救結果之相關性；並探討其到院後經急救措施介入，對急救結果與存活間是否有差異性。本研究採用回溯性方式，蒐集中部某醫學中心急診室2010年1月1日至2012年12月31日，年齡大於20歲非創傷性到院前心跳停止病人共402例之病歷回顧分析。結果發現運送到院方式、事件發生或目擊者發現至病人送達到院時間，間隔時間越短則復甦成功的機率愈高，呈統計性顯著差異 (p<0.05)是影響急救成功與否之關鍵。到院之初始心臟節律與初測體溫，均呈顯著差異(p<0.05），低體溫（<35℃）者復甦成功機率較低(P=0.001)。急救是否成功復甦與急救藥物施打、建立人工氣道等二項變數，均呈現顯著差異（p<0.05）。經逐步邏輯斯迴歸分析，篩選出到院前心跳停止之病人是否成功復甦的重要影響變項，依序為：事件發生至到院時間、呼吸衰竭疾病史、心臟衰竭疾病史、到院時體溫及是否簽署DNR關鍵字詞：非創傷性到院前心跳停止、恢復自發性循環、體溫 Based on the non-Traumatic adults suffering from Out-of-Hospital Cardiac Arrest (OHCA), this study try to understand the correlation of the results of different variables and to explore whether there is a differences patients’ survival with the intervention of first aid measures.A retrospective study was applied in gathering cases from the emergency room of a medical center in central Taiwan from January 1, 2010 to December 31, 2012, focusing on non-traumatic cardiac arrest patients with age over 20-years old. A total of 402 cases were collected.Results: The mean age of the samples studied is 74.1 years old, males accounted for 68.9%; patients suffering from chronic diseases require long-term tracking, hypertension takes the majority of causes( 31.8% ), followed by diabetes ( 25.6% ); mostly call for help with "coma"( 39.1% ). Between the above basic attributes and the return of spontaneous circulation (ROSC), there is no statistically significant difference, while it had a lot to do with ways of transportation of patients to the hospital, the length of time from the occurrence of events to the patient’s being rushed to the hospital by witnesses. It is found that the way transport to hospital as well as the duration of event occurred to the patient been rushed to hospital are critical .The initial cardiac rhythm and immediate measure of temperature upon reaching the hospital showed a statistically significant difference (p<0.05), those who with low temperature (<35 ℃) had lower chances of successful resuscitation (p=0.001). In addition, the appliance of emergency medical treatment and the construction of the artificial airway showed a statistically significant difference (p<0.05). According to Stepwise logistic regression analysis, the major impact variables accounting for the success of patients with respiratory failure before reaching the hospital returned to cardiac arrest resuscitation are listed in order as follows: the promptness to the hospital, medical history of respiratory failure or heart failure, temperature being taken upon reaching the hospital and whether to sign DNR.Keywords：OHCA, ROSC, Temperature
