A 24-year old student died from asphyxiation while filling flasks with liquid nitrogen. The upper and lower extremities and the back were frozen. The face, ears and neck were livid with a horizontal line of demarcation. A few wide ventricular complexes were seen in the initial ECG, followed by asystole. The patient's trachea was intubated, his lungs ventilated with 100% oxygen and CPR initiated. The site of larynx and pharynx were without pathological findings. 250 ml of a crystalloid solution were infused into the external jugular vein. It was not possible to measure the body temperature. Venous blood gas analysis showed a metabolic acidosis and hyperkaliaemia. CPR was terminated after 90 minutes. Own protection is most important for the rescue team if a nitrogen atmosphere is expected.
一名24岁的学生在往烧瓶中灌注液氮时因窒息死亡。其上下肢及背部均被冻伤。面部、耳朵和颈部呈青紫色，有一条水平分界线。初始心电图显示有少数宽大的心室复合波，随后出现心搏停止。对患者进行了气管插管，用100%氧气进行肺部通气并开始心肺复苏。喉和咽部未发现病理改变。将250毫升晶体溶液注入颈外静脉。无法测量体温。静脉血气分析显示代谢性酸中毒和高钾血症。90分钟后终止心肺复苏。如果预计存在氮气环境，对救援团队来说自身防护最为重要。
