It has been used for over 200 years as a means of eliminating poisons from the stomach. Such devices are normally used on a person who has ingested a poison or overdosed on a drug such as alcohol. They may also be used before surgery, to clear the contents of the digestive tract before it is opened. Apart from toxicology, gastric lavage (or nasogastric lavage) is sometimes used to confirm levels of bleeding from the upper gastrointestinal tract. It may play a role in the evaluation of hematemesis. It can also be used as a cooling technique for hyperthermic patients. ==Technique== Gastric lavage involves the passage of a tube (such as an ''Ewald tube'') via the mouth or nose down into the stomach followed by sequential administration and removal of small volumes of liquid. The placement of the tube in the stomach must be confirmed either by air insufflation while listening to the stomach, by pH testing a small amount of aspirated stomach contents, or x-ray. This is to ensure the tube is not in the lungs. In adults, small amounts of warm water or saline are administered and, via a siphoning action, removed again. In children, normal saline is used, as children are more at risk of developing hyponatremia if lavaged with water. Because of the possibility of vomiting, a suction device is always on hand in case of pulmonary aspiration of stomach contents. Lavage is repeated until the returning fluid shows no further gastric contents. If the patient is unconscious or cannot protect their airway then the patient should be intubated before performing lavage. The person must be put to sleep for a period of time during the operation due to its high risk of shock and hyponatremia. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gastric lavage」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
