血管扩张剂以其降低心脏负荷的作用,在治疗心源性休克时,确实可以取得良好的血液动力学效应。但是,在发挥其治疗作用的同时,又有可能引来十分重要的并发症,而其利弊之间,并无剂量上的严格界限。因此血管扩张剂的使用,必须在血液动力学严密监测下进行。同时要恰当地配合其他治疗措施,准确掌握用药时机,谨慎地调节剂量,才能取得一定的疗效。 Vasodilator with its role in reducing heart load, indeed can achieve good hemodynamic effects in the treatment of cardiogenic shock. However, in addition to exerting its therapeutic effect, it is likely to lead to very important complications with no strict limits on its dosage. Therefore, the use of vasodilators must be closely monitored by hemodynamics. At the same time should be properly coordinated with other treatment measures, accurately grasp the timing of medication, carefully adjust the dose in order to achieve a certain effect.
