美索比妥
別名: Brevital, Brevimytal, Brietal
藥物類別: Ultra-short acting barbiturate anesthetic
美索比妥是一種速效麻醉劑，僅在醫院環境中使用，用於手術或短暫處置前引導寵物進入睡眠狀態。 - **作用迅速**：它在幾秒鐘內即可生效，使獸醫團隊能快速確保寵物的呼吸道安全。 - **恢復期**：有些寵物（尤其是狗）在醒來時可能會經歷「不平穩的恢復」（如顫抖、興奮或發聲）。獸醫團隊會密切監測，並可能使用其他藥物來平緩此過程。 - **安全性**：在藥物作用期間，將持續監測寵物的心跳、呼吸和血壓。
劑量必須由獸醫依你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。
