心跳骤停是临床上一种最危急情况,其抢救成功率与心跳骤停的病因、停跳时间、急救措施的正确与否及客观自然条件密切相关。近年来,有用常规剂量肾上腺素复苏失败而改用大剂量肾上腺素复苏成功的报导,但应用多大剂量合适,尚是一个探讨问题,本文总结42例心跳骤停的病人复苏早期应用常规剂量肾上腺素及大剂量肾上腺素效果进行比较,发现应用大剂量的肾上腺素有利于自主循环迅速恢复。 Cardiac arrest is clinically the most critical situation, and its success rate of rescue and etiology of cardiac arrest, stop time, the correctness of first aid measures and objective and natural conditions are closely related. In recent years, the use of conventional doses of epinephrine failed to switch to high-dose adrenaline successful success of the report, but how much dose appropriate, is still a discussion of the problem, this paper summarizes the 42 cases of cardiac arrest in patients with early recovery of conventional dose of epinephrine And high-dose adrenaline compared, found that the application of large doses of epinephrine is conducive to rapid recovery of spontaneous circulation.
