胸腔手術需要作單側肺部通氣(one lung ventilation, OLV)使用雙管腔枝氣管內管(dou-ble lumen endobronchial tube)時,其主要併發症為氣道創傷及位置不正,造成缺氧甚至死亡,本文討論兩例左側枝氣管內管位置不正病人,發生輕度缺氧,我們以纖維光束內視觀看不把雙管腔內管往外拉出2公分,矯正內管位置,使缺氧情況獲得改善。
Double-lumen endobronchial tubes can be used to selectively collapse and/or selectively collapse and/or ventilate either lung during thoracic surgery. The major complications associated with these tubes are airway trauma and malpostion. Two cases of malposition of the left sided double-lumen tube was withdrawn 2cm and the tube’s position examined through the bronchoscope. Fol-lowing these maneuvers, the arterial blood gases were satisfactory.
