对疑有吸收不良的腹泻儿童作诊断检查时,一般用D-木糖试餐估计肠道吸收情况.囊性纤维化(CF)病人进食试餐后血中木糖水平明显高于对照组.本研究的目的是检查CF病人的营养吸收在粘膜水平是否有改变.作者使用等张溶液稳态灌注空肠,检查11例健康对照者和10例CF病人.稳态灌注时采用一种近端带气囊的四腔管,气囊通到空肠灌注部即曲氏靱带处.各种试验溶液借助蠕动泵以13ml/min的速
In case of suspected malabsorption of diarrhea in children for diagnostic tests, the general assessment of intestinal absorption of D-xylose test cases of patients with cystic fibrosis (CF) after eating meal blood xylose levels were significantly higher than the control group. The aim of this study was to examine whether there is a change in the mucosal level of nutrient absorption in patients with CF. The authors used steady-state perfusion of the jejunum with isotonic solution to examine 11 healthy controls and 10 CF patients.
