血止不住的希望!?

當被要求使用自費項目,尤其是費用奇高時,療效是否跟的上它的高貴!往往答案是否定的,其一,不能使用於常規,常常代表療效未被確認,其二,大部分都是非常規可使用於此適應證的藥物,也就是所謂的out-label use。 rFVIIa 是其中之一。

(Recombinant human factor VIIa; NovoSeven) 是使用在血友病患,在過去幾年,常為臨床醫師使用在大出血患者,無法止血的情況,在舊文的Massive transfusion protocol裡面有提到,這裡有兩種使用時機,一個是在傳統止血治療(血小板,凝血因子,拮抗劑)等無法奏效時,不得已為之,一種就是直接嵌入MTP的流程中,後一種情況,是比較爭議的,因為所謂的常規,就是要有直接的研究證據,顯示的確療效大於風險benefits out weight risks,且值得這個代價(藥價)。
