AIM: To investigate the effective emergency treat-ment on patients with cardiac and respiratory sudden arrest induced by severe hypokalemia. METHODS: A total of 4 patients with cardiac and respiratory sudden arrest induced by severe hypokalemia admitted into Emergency Department of Xi’an Aerospace General Hospital were selected as object of study. All patients were given central venous infusions of concentrated potas-sium chloride corrects hypokalemia by micro-pump on the basis of conventional cardiopulmonary cerebral resuscitation therapy. The curative effect and prognosis were observed. RESULTS: All the cardiopulmonary resuscitations were successful, and 3 cases were cured and discharged, 1 case died due to incurable multiple organ failure and refractory hypotension. No complications occurred due to high concentration of potassium supplement. CONCLUSION:On the basis of early effective cardiopulmonary cerebral resuscita-tion therapy, it’s an extremely effective method of treating patients with cardiac and respiratory sudden arrest induced by severe hypokalemia with central venous infusions of concentrated potassi-um chloride corrects hypokalemia by micro-pump, which can improve the successful ratio of resuscitation.%目的：探讨严重低钾血症致心跳呼吸骤停患者的有效急诊救治方法。方法：选取西安航天总医院急诊科收治的4例严重低钾血症致心跳呼吸骤停患者作为研究对象，在常规心肺脑复苏治疗的基础上，采用微量泵中心静脉泵推高浓度钾进行补钾治疗，观察其疗效及预后情况。结果：所有患者均心肺复苏成功，其中3例病情好转治愈出院，1例因出现多脏器衰竭，顽固性低血压，无法纠正而死亡。均未出现因高浓度补钾的并发症。结论：在早期正规有效的心肺复苏救治的基础上，采用中心静脉微量泵高浓度氯化钾溶液补钾是救治严重低钾血症所致心跳呼吸骤停的有效方法，可提高其复苏成功率。
