Nasogastric tube insertion is often difficult, due to a variety of reasons, e.g. skewed laryngeal anatomy. We present a previously unreported method of facilitating nasogastric tube insertion, using a flexible nasendoscope.
The nasogastric tube is anchored to a flexible nasendoscope using sodium alginate dressing ties. The nasendoscope is then passed into the upper oesophagus, along with the nasogastric tube. Once the nasogastric tube has passed the cricopharyngeus, gentle traction on the nasendoscope releases it from the nasogastric tube. The nasendoscope can then be withdrawn. A previous safety study of sodium alginate ingestion showed no adverse effects.
This method enables nasogastric tube insertion under direct vision, and allows the tube to be guided past the larynx and into the upper oesophagus.
由于多种原因，如喉部解剖结构异常，鼻胃管插入常常困难。我们介绍一种使用可弯曲鼻内镜辅助鼻胃管插入的此前未报道的方法。
用藻酸钠敷料带将鼻胃管固定在可弯曲鼻内镜上。然后将鼻内镜与鼻胃管一起插入食管上段。一旦鼻胃管通过环咽肌，轻轻牵拉鼻内镜使其与鼻胃管分离。然后可将鼻内镜撤出。此前关于藻酸钠摄入的安全性研究显示无不良反应。
该方法可在直视下插入鼻胃管，并能引导鼻胃管越过喉部进入食管上段。
