普外科老年患者的营养状况分析

Evaluation of Nutritional status of surgical in patients over 60-year

目的 应用微型营养评定 (MNA)方法调查和分析普外科住院老年患者术前的营养状况。方法 115例普外科老年患者接受MNA的问卷调查、人体测量学检测和临床实验室检查。结果 ①根据MNA得分 ,普外科老年患者中有 3例 (2 .6% )属营养不良 ,68例 (5 9.1% )属营养不良高危人群 ;而社区居民中仅分别有 2例 (1.7% )和 2 2例 (19.1% )出现相应程度的营养不良。②根据上臂围、TSF和上臂肌围测得值患者营养不良发生率分别为 3 3 .1%、2 5 .2 %和 3 2 .2 %。③根据实验室检查 ,包括血浆白蛋白水平和总淋巴细胞计数 ,患者营养不良发生率分别为 2 0 %、2 3 %。④普外科老年患者的MNA得分与BMI、上臂围、TSF、上臂肌围、血浆白蛋白、总淋巴细胞计数的相关性均有统计学意义。结论 ①普外科住院老年患者中营养不良和营养不良高危状态的发生率高于社区老人 ,必须加强营养干预。②提倡在普外科老年患者中应用MNA问卷进行营养状况评估 ,以供临床治疗参考。

Objectives To assess the nutritional status of surgical patients over 60-year by mini nutritional assessment(MNA).Methods MNA questionnaire,anthropometric parameters and laboratory test were performed in 115 patients.Results According to the scores of MNA,3(2.6%)patients were of malnutrition and 68(59.1%)patients were at risk of malnutrition.However,2(1.7%)and 22(19.1%) were of malnutrition and at risk of malnutrition respectively in community-dwelling elder persons. According to each single index,midarm circumference,TSF and midarm muscle circumference,prevalence of malnutrition was 33.1 %,25.2% and 32.2% respectively in patients.According to laboratory test,including serum albumin,lymphocyte,prevalence of malnutrition was 20% and 23% respectively in patients.MNA score was correlated significantly with BMI,MAC,TSF,AMC,serum albumin and lymphocytes.Conclusion The prevalence of malnutrition and at risk of malnutrition is higher in hospitalized patients than that in community-dwelling elder persons,so nutritional intervene should be enhanced.MNA questionnaire should be used in the preoperative nutritional evaluation of elderly patients to be the reference of clinic treatment.
