心室纤颤出现之前用利多卡因可使心肌梗塞患者因心律紊乱致死率剧减.作者提出,对有①频发室早;②多源性室早;③短阵性室性心动过速;④R、T重叠的室早等心室纤颤前驱表现者,以及有发生心室纤颤可能的患者在护送途中,为予防心室纤颤肌注利多卡因比静滴方便、安全. 心室纤颤发生时,需立即用电除颤或静滴利多卡因,除颤后可肌注利多卡因维持. 肌注方法,可在双臀深部各注射2%的利多卡因
Premature ventricular fibrillation with lidocaine myocardial infarction patients can be due to cardiac rhythm fatal rate drastic reduction. The authors suggest that there ① frequency of early; ② multi-ventricular premature ventricular tachycardia; ④ R, T overlap early ventricular fibrillation precursors, and those who may have ventricular fibrillation during escort, in order to prevent ventricular fibrillation intramuscular injection of lidocaine more convenient and safe than infusion, when ventricular fibrillation occurs , The need for immediate defibrillation or intravenous lidocaine, after defibrillation can be intramuscular lidocaine intramuscular injection method, in the double hip deep injection of 2% lidocaine
