经鼻胃管置入技术 Introduction
是指经一侧鼻腔插入胃内，用于胃 肠减压或灌注（食物、水、药物等） 以达到治疗目的。
By inserting a nasogastric tube, you are gaining access to the stomach and its contents. This enables you to drain gastric contents, decompress the stomach, obtain a specimen of the gastric contents, or introduce a passage into the GI tract. This will allow you to treat gastric immobility, and bowel obstruction. It will also allow for drainage and/or lavage in drug overdosage or poisoning. In trauma settings, NG tubes can be used to aid in the prevention of vomiting and aspiration, as well as for assessment of GI bleeding. NG tubes can also be used for enteral feeding initially.
