ICU机械通气患者肠内外营养支持治疗的效果比较

目的 探讨不同途径的营养支持治疗ICU接受机械通气患者的效果. 方法 将ICU内60例接受机械通气的患者随机分为肠内营养组（EN,32例）和全肠外营养组（TPN,28例）.EN和TPN组患者均接受等氮、等热量营养支持,监测两组间治疗前后的血清白蛋白、血红蛋白、机械通气时间、上臂肌肉周径和肱三头肌皮皱褶厚度,并计算氮平衡. 结果 上臂肌围和肱三头肌皮皱厚度两组对比差异无统计学意义（P〉0.05）;肠内营养组的血清白蛋白、血红蛋白和氮平衡均较对照组增高（P〈0.05）;机械通气时间EN组低于TPN组（P〈0.05）. 结论 ICU机械通气病人肠内营养支持治疗较肠外营养支持治疗能更好地提供营养底物,并有效地缩短机械通气时间.

The comparison of enteral and parenteral nutritional support for mechanical ventilation patients in ICU

Objective To observe the effects of enteral and pareuteral nutrition support for mechanical ventilation patients in ICU. Methods Sixty patients with mechanical ventilation in ICU were randomly assigned to two groups： one supported with enteral nutrition （32 cases） and another with parenteral nutrition （28 eases）. All patieuts received the same energy and same nitrogen. The levels of serum albumin, hemoglobin were detected, the ven tilation time, the thickness of skin fold at musculus triceps branchii and muscular perimeter of the arm were measured, and the nitrogen equilibrium was calculated. Results The levels of serum albumin and hemoglobin and nitrogen equilibrium were higher in enteral groups （ P 〈 0. 05 ）. No difference was observed in the thickness of skin fold at museulus triceps branehii and muscular perimeter of the ann between two group （ P 〉 0. 05 ）, and mechanical ventilation time in the enteral nutrition group was shorter than that in parenteral nutrition groups （ P 〈 0.05 ）. Conclusion For ICU patients, enteral nutrition has a better effect in nutrition support and can shorten the ventilation time.
