Accidental hypothermia is defined as an unintentional decrease in body temperature to below 35°C, and cases in which temperatures drop below 28°C are considered severe and have a high mortality rate. This study presents the case of a 57-year-old man discovered drifting at sea who was admitted to our hospital suffering from cardiac arrest. Upon admittance, an electrocardiogram indicated asystole, and the patient's temperature was 22°C. Thirty minutes of standard CPR and external rewarming were ineffective in raising his temperature. However, although he had been in cardiac arrest for nearly 2 h, it was decided to continue resuscitation, and a cardiopulmonary bypass (CPB) was initiated. CPB was successful in gradually rewarming the patient and restoring spontaneous circulation. After approximately 1 month of rehabilitation, the patient was subsequently discharged, displaying no neurological deficits. The successful recovery in this case suggests that CPB can be considered a useful way to treat severe hypothermia, particularly in those suffering from cardiac arrest.
意外低温是指体温意外降至35°C以下，体温降至28°C以下的病例被认为是严重的，死亡率很高。本研究报告了一例57岁男性的病例，该患者被发现漂浮在海上，因心脏骤停被送往我院。入院时，心电图显示心搏停止，患者体温为22°C。30分钟的标准心肺复苏和外部复温未能提高他的体温。然而，尽管他心脏骤停近2小时，但仍决定继续进行复苏，并启动了体外循环（CPB）。CPB成功地使患者逐渐复温并恢复了自主循环。经过大约1个月的康复，患者随后出院，未显示神经功能缺损。该病例的成功康复表明，CPB可被视为治疗严重低温的一种有效方法，特别是对于心脏骤停患者。
