Indsci英思科壁挂式中国(国产)C4H10O乙醚红外原理气体检测仪
美国英思科气体检测仪是全球知名的设计制造和销售工业级便携式和固定式有毒有害气体检测仪的专业公司,Industrial Scientific已成为全球坚固可靠的气体监测仪器(系统)的代名词。其前身是美国国家矿业服务公司的研发部,曾为美国的矿山安全提供了大量的井下安全检测仪器。1976年,该研发部改制成为美国英思科公司。锡安站群是英思科气体检测仪的中国代理商,主要销售的仪器型号有:M40,T40,MX6,MX4,iTX,GB90,JCB4,iTrans,GasBadgePro等。
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。
