药物名称:七氟烷

英文名:Sevoflurane

别名: 七氟醚,七氟异丙甲醚,七氟烷
外文名: Sevoflurane, Travenol
适应症:
诱导和苏醒较现有的强效麻醉药快。对心血管影响比异氟烷小,心律失常少见,与肾上腺素合用无妨;有良好的肌松作用,随麻醉加深呼吸抑制加重,但较氟烷轻;对脑血流量、颅内压影响与异氟烷相似,未见明显的肝损害。
用量用法:
麻醉诱导系用50%~70%氧化亚氮,2.5%~4.5%七氟烷,然后静注琥珀胆碱,作气管插管。麻醉维持吸入O22L/min,N2O4L/min,和本品〉4%。小儿麻醉选用本品,麻醉诱导和苏醒迅速,对呼吸循环影响小。
注意事项:
有报道本品可能产生恶性高热,它继发于体温调节中枢受损。目前本品已在临床应用。
