肠内营养支持在危重病中的应用研究

目的：观察肠内营养在危重病中的支持效果。方法：将ＩＣＵ中２６例危重患者随机分为肠内营养支持组（１４例）和肠外营养支持组（１２例），在营养支持前１日及营养支持第１０日测量三头肌皱厚度，上臂肌围，血清白蛋白及血红蛋白，每日计算氮平衡并观察相关并发症情况。

Application of enteral nutrition in critically ill patients

Objective:To observe the effect of enteral nutrition on critically ill patients.Methods:26 critically ill patients in intensive care unit were randomly assigned to two groups,one supported with enteral nutrition (14 cases) and another with parenteral nutrition (12 cases).One day before and 10 days after nutritional support was given,the thickness of skin fold at musculus triceps brachii and muscular perimeter of the arm were measured,and serum albumin and hemoglobin levels were determined.Also,nitrogen equilibrium was calculated everyday and relative complications were recorded.Results:No differences were observed between the two groups in the thickness of skin fold at musculus triceps brachii and muscular perimeter of the arm (all P >0 05).With regard to albumin and hemoglobin levels and nitrogen equilibrium,enteral nutrition group was superior to parenteral nutrition group (all P <0 05).Conclusions:For critically ill patients,enteral nutrition plays a role in preventing bacterial translocation and subsequent multiple organ failure.Enteral nutrition has better nutritional effect in addition to the merits of low cost,less complications and easy performance.
