急診室來了一個喘到不行、血氧直直落的急性肺栓塞病人,直覺反應就是插管、給氧、保護氣道——但這一集要講的剛好相反:對肺栓塞病人來說,插管這個動作本身,可能就是壓垮他的最後一根稻草。為什麼一個血壓看起來還撐得住的病人,鎮靜誘導藥一打、正壓一上,就會瞬間崩盤?答案藏在那顆被後負荷逼到極限、正卡在「右心死亡螺旋」邊緣的右心室。起點是 JournalFeed 介紹的一篇 2026 年急診醫學世代研究(Dhar et al., Acad Emerg Med):51 位插管的急性 PE 病人,插管後三小時內超過一半需要加重升壓藥、12% 心跳停止、10% 用葉克膜,中央型 PE 與右心吃力(超音波 OR 約 8 倍)是風險放大器。本集從這份研究出發,結合 2024 系統性回顧與 2026 AHA/ACC 新指引,帶你看懂崩潰的機轉、誘導藥怎麼選(ketamine 的老禁忌翻案、etomidate 與 propofol 的取捨)、升壓藥第一線到第二線的選法、PEEP 的 U 形曲線、為什麼肺栓塞不能用「允許性高碳酸血症」、液體該不該灌,以及新指引「能不插就不插、先穩血壓、備好葉克膜救援」的操作邏輯。我們也會誠實標出每個處置背後的證據有多薄。
