Simple insertion of a nasogastric (NG) tube was successful in only 52 of 100 anesthetized intubated patients. After the larynx was manually pulled forward, the NG tube was successfully inserted in 33 patients. In the remaining 15 patients, the NG tube was inserted only with the aid of a finger or a laryngoscope used with Magill forceps. The difficulty of NG tube insertion was not correlated with sex, age, weight, or type of endotracheal intubation. Forward displacement of the larynx by manually gripping and lifting the thyroid cartilage is a useful and safe maneuver that facilitates NG tube insertion in anesthetized intubated patients.
在100例麻醉插管患者中，单纯插入鼻胃管（NG）仅52例成功。手动将喉部向前牵拉后，33例患者成功插入鼻胃管。其余15例患者仅借助手指或与麦吉尔钳配合使用的喉镜插入鼻胃管。鼻胃管插入的难度与性别、年龄、体重或气管插管类型无关。通过手动握持并提起甲状软骨使喉部向前移位是一种有用且安全的操作，有助于在麻醉插管患者中插入鼻胃管。
