心肺复苏方法的进展若有心脏骤停的先兆,例如血压突然下降、心动过缓或甚至开始室颤,但病人仍清醒时,可让病人有规律地每1～3秒钟咳嗽一次。这样可使血压回升,从而避免心脏骤停。 Bacaner复习近年来的文献,认为溴苄铵能提高室颤阈值,加强心脏收缩和降低周围血管阻力。为预防室颤或已有室速时,可用溴苄铵负荷量500毫克(7～10毫克/公斤)肌肉注射或稀释于50毫升盐水,于6～10分钟内静脉注射。凡疑为心肌梗塞者,可尽早使用。维持量为2～3克/天,可静脉滴注1～3毫克/分或每6小时肌肉注射500毫克。在试图电除颤前就应静脉注射未稀释的溴苄铵500～1000毫 Progress in Cardiopulmonary Resuscitation If there are signs of cardiac arrest such as a sudden drop in blood pressure, bradycardia or even VF, when the patient is awake, the patient can be coughed regularly every 1 to 3 seconds. This will allow blood pressure to rise, thus avoiding cardiac arrest. Bacaner reviews recent literature that bromobenzyl ammonium can increase the threshold of ventricular fibrillation, enhance cardiac contractility and reduce peripheral vascular resistance. In order to prevent ventricular fibrillation or ventricular tachyarrhythmias, 500 mg (7-10 mg / kg) of brombenzamid can be intramuscularly or diluted in 50 ml of saline and injected intravenously within 6 to 10 minutes. Who suspected of myocardial infarction, may be used as soon as possible. Maintenance dose of 2 to 3 grams / day, intravenous infusion of 1 to 3 mg / min or intramuscular injection of 500 mg every 6 hours. Before attempting defibrillation should be intravenous injection of undiluted benzyl ammonium bromide 500 ~ 1000 milliliters
