到院前使用iLMA使OHCA病人存活率更高

根據一份台灣於2010年發表的研究,救護人員使用iLMA,比起使用傳統的BVM(ambu bag
,甦醒球)更能提高OHCA(到院前心肺停止)病人的存活率。
在過去我們並沒有證據說,到院前使用iLMA會對OHCA病人存活率有幫忙。在這份研究中,
研究者分析了台南市EMS所提供的資料,將2004~2007年共398位OHCA病人,分為使用iLMA
(共309人),與使用 BVM(89人) 兩組。
結果發現,到院前使用iLMA的病人,其24小時存活率顯著高於只使用BVM的病人,分別是
36.2%與24.7%。

本文其他值得注意的小地方:
1. 經過訓練EMT可以在很短的時間內用iLMA建立呼吸道(平均37.2秒)。
2. 使用iLMA的病人,在到院後的血氧濃度比使用BVM的病人稍高,表示iLMA的通氣功能可
能較好,但兩筆數據未達統計上的顯著差異。
閒聊:
我8年前(2004年)受T1訓的時候,LMA這個東西只是"耳聞",從未見到真面目。而且我對
BVM的那個甚麼"CE手勢"一直很肚爛,我手小不容易壓好。
後來幾年前考T2的時候,LMA也只是摸個幾把而已,沒甚麼機會在訓練中多玩幾次。雖說
如此,近兩三年各縣市消防局越來越積極推LMA,可見大家對這個新玩具的態度也逐漸改
變。
現在既然iLMA在到院前的使用已經有實證基礎,如果碰到OHCA,手邊又有LMA,那麼就別
吝嗇拿它來建立一個呼吸道吧!當然BVM在到院前依舊有其價值,但它與iLMA/LMA相比,
最大缺點是在到院前的運輸途中,難以維持固定,導致通氣效果可能較差。
這裡有一篇一位Paramedic寫的文章,

很有水準,
文章後半段提到了iLMA,
有興趣的EMT們可以看一看。
