美国达拉斯消息:一种新的静脉β-阻滞剂——甲氧丙心安(Esmolol)能快速控制术后心动过速病人的心率达24小时。在洛杉矶进行的研究表明,最初用药1—15分钟可控制心率,与所有治疗此种并发症的常规药物相比,甲氧丙心安的“独特优点”是在一极短时间内开始作用和消失。研究人员告诉此地美国胸科医师学会的医师们,甲氧丙心安可恢复窦性节律,并易于耐受,但少数病人可能引起低血压,从而限制治疗。 Richard Gray等在洛杉矶Cedars-sinai医学中心进行此项研究。目的是评价甲氧丙心安快速控制心率的安全性和有效性。对于这项分析,他们选择心率减慢15％或转变成窦性节律作为研究的终点。 Gray说,研究对象为心血管外科手术后 Dallas, United States: A new intravenous β-blocker, Esmolol, rapidly controls heart rate in patients with tachycardia after 24 hours. A study in Los Angeles showed that initial administration of the drug for 1-15 minutes controls heart rate and that the “unique advantage” of methamphetamine is its onset and disappearance in a very short period of time compared with all conventional medicines used to treat such complications . Researchers told physicians at the American College of Chest Physicians here that methoxybenzamide regains sinus rhythm and is easily tolerated, but few patients may cause hypotension and thus limit treatment. Richard Gray et al. Conducted this study at the Cedars-Sinai Medical Center in Los Angeles. The goal is to evaluate the safety and efficacy of methoxybenzamide for rapid heart rate control. For this analysis, they chose to slow their heart rate by 15% or switch to sinus rhythm as the end of the study. Gray said the study was conducted after cardiovascular surgery
