老年病人鼻饲营养调查

对11名69～83岁不能自然进食的男性鼻饲病人进行了全面的营养调查,平均每人每日热能摄取为1722kcal,而热能消耗在1300～1700kcal之间。蛋白质、脂肪和碳水化物每人每日平均摄入82.4、72.5、185.0g,分别占总产热量19.1、37.9、和43.0％。动物蛋白质和动物脂肪分别占总蛋白和总脂肪的71.9和69.3％,蛋白质量较优。脂肪总量虽不太高,但占总产热量偏大,碳水化物嫌少,而(?)(?)(?)投入939mg,摄入过多。钙、磷、铁摄入充裕,可满足需要。维生素A、核黄素也可满足需要,但硫胺素、尼克酸和抗坏血酸摄入量不足。这些都还需要改进。

NUTRITIONAL SURVEY AND ASSESSMENT OF ELDERLY PATIENTS ON NASOGASTRIC FEEDING

Nutritional studies were made on eleven elderly male hospitalized patients (60-83 years old) receiving nasogastric feeding for from several months to as long as 10 years duration.The major nutrients intake obtained was listed in table 1. According to the physical examination, biochemical parameter of the blood and nitrogen balance, the average intake 1722 kcal of enegy (1175-2700 kcal) and 82.4 g of protein (52.6-117.3g) probably met the need of the patients. Vitamin status (B1 B2 C) by blood and urine examination was rather good because of taking additional vitamin preparation regularly daily besides meal sources. Blood cholesterol concentration was moderately higher (339.3mg/dl) than the normal value possibly due to excessive daily intake. It suggested that the intake of cholesterol should be restricted.A better nasogastric feeding regimen was presented and discussed.
