Epinephrine is one of the most potent vasopressor drugs known . 肾上腺素是已知最强的升压药之一。

Therefore , meticulous calculation in fluid resuscitation together with vasopressors or inotropics support is important in dealing with neurogenic shock 因此，谨慎给予输液以及在必要时给予升压剂或强心剂是非常重要的。

Renin - angiotensin system ( ras ) plays an important role in the regulation of peripheric blood pressure , where angiotensin converting enzyme ( ace ) is considered to be the core of the system . ace plays a key role in increasing the blood pressure by catalyzing the formation of the potent vasopressor angiotensin ii ( ang ii ) from angiotensin i ( ang i ) 在该系统中， ace酶是血压调节过程中一个关键的酶，它可以将无活性的血管紧张素( ang )水解生成具有血管收缩作用的血管紧张素( ang ) ，从而导致血管收缩，机体的血压升高。

Adequate preoperative fluid hydration , intensive hemodynamic monitoring , ready - prepared blood and vasopressor drugs , inspiration of 100 percent oxygen , and copious irrigation of marrow debris after reaming are useful prophylactic methods to lower the catastrophic complication during cementation 足够的术前水分补给，手术中精细的生命徵象监视，随时准备好的血液及增压药物以备不时之需，呼吸纯氧以预防低血氧症，在骨髓腔管被扩钻后使用大量的水清洗骨髓腔管内的杂质，这些是降低骨水泥心脏血管衰竭并发症发生的有效方法。
