通用名称:乙醚
英文名称:Ether
中文别名:麻醉乙醚
英文别名:Aether Anaestheticus、Anaesth、Anaesthetic Ether、Diethy Ether、Diethyl Ether
【药理】
1.优点①镇痛作用强,又可促使骨骼肌松弛;②3—4倍于常用量时,对循环功能的抑制才达到危险的地步,故较安全;③直接的麻醉死亡率低。
2.缺点①易燃烧爆炸,当空气中含量为 1.83—48.0%,氧气中 2.1—82.5%,即有此可能;乙醚的蒸气密度较空气大 2—6倍,常下降在手术室地面,容易着火;②气味不佳,刺激性强,能促使口鼻腔和气管支气管粘膜、粘液腺分泌增多,气道难以保证通畅,吸入全麻诱导中,屏气、呛咳、喉或支气管痉挛时常发生,术后肺部并发症多;③化学性质不稳定,暴露于空气中,遇光或受热即变质,生成过氧化物或乙醛,刺激性更强;纯度要求高,微量的杂质即增加全麻诱导和维持的困难,事后并发症更多;④全麻的作用起效慢,诱导期不仅太长,且可有兴奋阶段,临床上需另用全麻诱导药;⑤苏醒期间胃肠道紊乱常见,恶心呕吐发生率可高达 50%以上;⑥乙醚麻醉时,胆汁分泌减少,肝糖原耗竭,血糖升高,这些改变对正常人可无重要意义,但对核尿病患者或肝脏病变者则未必然。
