ICU机械通气患者肠内外营养的比较研究

目的:探讨不同营养支持对ICU内接受机械通气患者的治疗效果。方法:将ICU内30例接受机械通气的患者随机分为两组:肠内营养组(EN,16例)和全肠外营养组(TPN,14例)。EN和TPN组患者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、上臂肌围和肱三头肌皮皱厚度,并计算氮平衡。结果: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),上臂肌围和肱三头肌皮皱厚度两组对比无显著差异(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较肠外营养能更好的提供营养,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 parenteral nutrition support for mechanical ventilation patients in ICU. Methods： 30 patients with mechanical ventilation in ICU were randomly assigned to two groups：one supported with enteral nutrition（16 cases） and another with parenteral nutrition（14 cases）. All patients received the same energy and ＇same nitrogen. The levels of serum albumin, hemoglobin were detected, the ventilation time, the thickness of skin fold at museulus 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 rauseulus triceps branchii and muscular perimeter of the arm between two group（P〉0. 05）, and mechanical ventilation time in the EN group time 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.
