The survival to discharge rate after unwitnessed, non-cardiac out-of-hospital cardiac arrest (OHCA) is dismal. We report the successful use of therapeutic hypothermia in a 26-year old woman with OHCA due to intentional poisoning with heroin, amphetamine and insulin.The cardiac arrest was not witnessed, no bystander CPR was initiated, the time interval from the call to ambulance arrival was 9 minutes and the initial cardiac rhythm was asystole. Eight minutes of advanced cardiac life support resulted in ROSC.Upon hospital admission, the patient's pupils were dilated. Her arterial lactate was 17 mmol/l, base excess -20, pH 6.9 and serum glucose 0.2 mmol/l. During the first 24 hours in the ICU, the patient developed maximally dilated pupils not reacting to light and became increasingly haemodynamically unstable, requiring both inotropic support and massive fluid resuscitation. After 1 week in the ICU, however, she made an uneventful recovery with a Cerebral Performance Category of 1 at hospital discharge and at a follow up examination at 6 months.
According to most prognostic factors, the patient had a statistical chance for survival of less than 1%, not taking into account her severe state of hypoglyaemia. We suggest that this case exemplifies the need for more studies on the use of TH in non-coronary causes of OHCA.
未观察到的院外心脏骤停(OHCA)后出院存活率很低。我们报告了一例成功使用治疗性低温的病例,该患者为 26 岁女性,因故意服用海洛因、苯丙胺和胰岛素而发生 OHCA。心脏骤停未被目击,没有旁观者进行心肺复苏,从呼叫到救护车到达的时间间隔为 9 分钟,初始心搏节律为心搏停止。经过 8 分钟的高级心脏生命支持,患者恢复了自主循环。入院时,患者的瞳孔扩大。她的动脉乳酸为 17mmol/L,碱缺失-20,pH 值为 6.9,血糖为 0.2mmol/L。在 ICU 的前 24 小时内,患者出现最大程度的瞳孔散大,对光无反应,且血流动力学越来越不稳定,需要正性肌力支持和大量液体复苏。然而,在 ICU 1 周后,她恢复良好,出院时的脑功能预后评分(Cerebral Performance Category)为 1,6 个月随访时无异常。
根据大多数预后因素,患者的生存统计机会不到 1%,且未考虑到她严重的低血糖状态。我们建议,该病例说明了需要更多研究治疗性低温在非冠状动脉性 OHCA 中的应用。
