老年危重病患者营养状况的临床研究

The clinical investigation of nutrition support for elderly critical patients in ICU

目的探讨老年危重病患者的营养状况和营养支持治疗情况。方法回顾性分析85例老年危重病患者的营养支持治疗情况及其与疾病预后的关系。结果存活组患者的体质量指数高于死亡组(P<0.05);入院当日存活组患者血红蛋白和白蛋白高于死亡组(P<0.05);在入住ICU第10天时,存活组患者胃肠外非氮热卡供给量和非氮热/氮均小于死亡组(P<0.05),而血清白蛋白则高于死亡组(P<0.01)。结论老年危重病患者的救治过程中,存在能量供给不足,及时选择合理的营养支持方式,补充必需的能量,有助于改善患者疾病的转归。

Objective To evaluate the current nutritional status and nutrition support for elderly critical patients. Method The relationship between the nutrition support and prognosis of 85 elderly critical patients in ICU was investigated retrospectively. Results The BMI of patients in survival group was higher than that in death group （ P 〈 0. 05 ） , and haemoglobin and serum albumin in survival group were also higher than that in death group in first day in ICU （ P 〈 0. 05 ）. In the tenth day, the support of parenteral nutrition and nonprotein-calorie/nitrogen in survival group was less than these in death group （P 〈0. 05） ,but serum albumin in survival group was higher （P 〈0. 01 ）. Conclusions During the treatment of elderly critical patients, the nutrition support was usually deficient, the effective way of nutrition support therapy should be chosen and essential energy should be supplied, which can help to improve the prognosis of elderly critical patients.
