在危重病人中,由于心输出量的降低而使重要器官灌注减少的情况是经常发生的。对组织灌注不良的治疗,目的在于提高心输出量并合理分配血流,尤其是对脑、肾、冠状动脉和肠系膜血管床的血供。在强调改善血流量的同时,必须保持最低动脉收缩压不低于80mmHg,以保证冠状动脉有足够的灌注压力。在调节心室前负荷不足以提高心肌工作能力时,必须考虑使用正心肌力药物。这些
Of critically ill patients, it is not uncommon for reductions in vital organ perfusion due to decreased cardiac output. Treatment of poor tissue perfusion aims to increase cardiac output and distribute blood flow appropriately, especially to the blood supply to the brain, kidney, coronary and mesenteric vascular beds. In emphasizing the improvement of blood flow at the same time, we must maintain the minimum systolic blood pressure not less than 80mmHg, in order to ensure adequate coronary perfusion pressure. Before adjusting the ventricular load is not enough to improve the ability to work, you must consider the use of positive cardiac drug. These ones
