A nutrient enema, also known as feeding per rectum, rectal alimentation, or rectal feeding, is an enema administered with the intent of providing nutrition when normal eating is not possible. Although this treatment is ancient, dating back at least to Galen and a common technique in 19th century medicine, nutrient enemas have been superseded in modern medical care by tube feeding and intravenous feeding. A variety of different mixes have been used for nutrient enemas throughout history. A paper published in ''Nature'' in 1926 stated that because the rectum and lower digestive tract lack digestive enzymes, it is likely that only the end-products of normal digestion such as sugars, amino acids, salt and alcohol, will be absorbed. This treatment was given to U.S. President James A. Garfield after his shooting in 1881, and is asserted to have prolonged his life.〔Bliss, D. W. "Feeding Per Rectum: As Illustrated in the Case of the Late President Garfield and Others". Washington: N.p., n.d. Rpt. from the Medical Record, July 15, 1882.〕 When the United States Senate Intelligence Committee published an unclassified summary of its 6,000 page classified report on the CIA's use of torture, its previously unknown use of "rectal rehydration" for punishment and torture became apparent.〔 〕〔 〕 == See also == * Murphy drip 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「Nutrient enema」の詳細全文を読む スポンサード リンク
