作者对10例二尖瓣狭窄及肺充血病人,同时进行血流动力学及心脏放射图测定,以评价多巴酚丁胺(DB,5毫克/公斤/分)、消心痛(ISD10毫克舌下含化)或二者并用的近期效应。单用DB,出现心脏指数从2.9±0.1显著增加至3.7±0.2升/分/米~2的效应(P<0.01),但肺动脉舒张压(PADP)及肺血容量仅轻度增加约15％左右。单用ISD引起肺动脉舒张压下降,从26±2降至
In 10 patients with mitral stenosis and pulmonary congestion, the authors performed both hemodynamic and cardiac radiographic measurements to evaluate the effects of dobutamine (DB, 5 mg / kg / min), resolving heartburn (ISD 10 mg sublingual Containing) or a combination of the two and the recent effects. With DB alone, the cardiac index increased significantly from 2.9 ± 0.1 to 3.7 ± 0.2 L / min / 2 (P <0.01), but pulmonary artery diastolic pressure (PADP) and pulmonary blood volume increased only slightly by about 15% about. Pulmonary artery diastolic pressure decreased with ISD alone, down from 26 ± 2
