Airway Exchange Catheter (AEC) is a long, small ID, hollow, semirigid catheter designed to be inseted through an endotracheal tube. Gnerally, AEC is utilized to change endotracheal tubes (ETTs) with highrer safety. In this workshop, we will focus on the protocol of changing endotracheal tube by an AEC. Clinical practice issues include 1) resistance to pass an ETT over an AEC , 2) confirmation of an AEC in correct position, 3) proper sizing of AECs for ETTs replacement, 4) it should be cautious about barotrauma from air entry and mechnical trauma.
氣管內管換管通條是一種長的、小口徑、中空、半堅硬的導管,可置放於氣管內管內,通常用於更換氣管內管與,拔管後提供氧氣或再次插管之通條
使用注意事項：
1. 換管時置入新的氣管內管阻力過大 :
1)忌用力太過 ;2) 將氣管內管與換管通條逆時針旋轉;3) 喉部施外力
(BURP); 4)使用喉頭鏡協助,開口提舌
2. 避免換管通條被拉出,位置維持在氣管內
1)換管通條標註深度記; 2)接二氧化碳監視器 ;3)經由通條聽呼吸音
3. 依據氣管內管尺碼選擇合適號數換管通條, 減少換管通條與氣管內管之間的空隙, 可降低置入氣管內管失敗之風險
4. 注意併發症, 成人換管通條深度勿超過26公分,避免支氣管穿孔;若用噴射呼吸(jet ventilation),壓力小於25psi,時間小於1秒,避免氣壓傷 (barotrauma)
