常用的肌松药并非全无危险,主要在各种肌松药仍不能消除其对心血管系统的副作用。一般认为,这类心血管副作用是由外周植物神经的兴奋或抑制、血管肥大细胞释放的组胺及其它血管活性物质、以及继发于运动终板去极化后的血钾升高所致。目前临床上最常用的肌松药有琥珀胆碱、筒箭毒、二甲筒箭毒(Metocurine)和本可松(Pancuronium)。经比较,多认为不致引起心血管副作用的本可松较有发展前途。近年又见具有心血管稳定特性的埃屈
Commonly used muscle relaxants are not completely without danger, mainly in a variety of muscle relaxants still can not eliminate its cardiovascular system side effects. It is generally believed that such cardiovascular side effects are caused by the excitability or suppression of peripheral autonomic nerves, the release of histamine and other vasoactive substances from vascular mast cells, and the elevation of serum potassium secondary to motor depolarization. At present, the most commonly used muscle relaxants are succinylcholine, myostatin, metocurine and pancuronium. After comparison, many think that will not cause cardiovascular side effects of the pine may have more development prospects. In recent years see also has the cardiovascular stability characteristics of EQ
