问题 单项选择题 B1型题

需长期肠内营养的十二指肠外瘘患者在术中应对其进行()。

A.经鼻胃管

B.经鼻空肠管

C.胃造瘘

D.空肠造瘘

E.经鼻十二指肠管

答案

参考答案:D

解析:1.空肠造瘘的喂养管可长期放置,适用于长期营养支持,且空肠造瘘使得肠道营养与胃十二指肠减压同时进行,适合于十二指肠外瘘患者。因此,对需长期肠内营养的十二指肠外瘘患者应采用空肠造瘘,故选D。2.经鼻胃管喂养的优点是胃的容量大,对营养液的渗透压不敏感,缺点是有发生吸入性肺炎的危险,不适合长期营养支持的患者。所以,对于需短期肠内营养、胃肠功能良好的患者适合经鼻胃管,故选A。3.胃造瘘不易发生肺部并发症,适合长期营养支持的患者,因此,肺部并发症危险性大、胃肠功能良好的患者适合胃造瘘,故选C。

 Dear Peter,

     I know that you are coming to Hefei next week. Welcome to my home. Let me tell you the way to my

 house. You will live in Changjiang Hotel on Changjiang Street, won't you? OK! Changjiang Street is a

 famous and busy street in our city. You can start from your hotel and go straight along Tongcheng Street. 

 You pass two small streets: Hongxing Street and Lujiang Street. When you see an overbridge (高架桥),

 please turn right and go along Huangcheng Street. It's an old street, but it's clean. There's a big park on

 the street. It's beautiful and clean. When you get to Jinzhai Street, please turn left and go along it. You
