摘要
目的探讨营养支持对接受机械通气患者的早期治疗作用。方法将接受机械通气治疗的45例危重病患者随机分为全肠外营养(PN)组、全营养食物均浆肠内营养(EN)组和肠内肠外营养相结合(PN+EN)组,各组患者均接受等氮等热量营养支持。结果各组脱机时间比较无显著性差异,营养效果相似,肠外组和混合组较快达氮平衡。肠外组和混合组的胃肠道并发症较肠内组少,两者比较有显著性差异。肠内组费用最便宜,混合组免疫学指标最高。结论机械通气患者普遍存在营养不良,可采用肠内营养或肠外营养或二者结合方式进行营养,肠内营养经济方便,有利于肠道能力恢复,而全肠外营养效果准确迅速,两者结合能互相取长补短。
Objective To explore the effect of nutrition support for patients with early Mechanical
Ventilafion （MV）. Methods Forty five critical patients with MV were included in the study. They were randomly divided into three groups ： total parenteral nutrition （TPN） group, enteral nutrition （EN） group and combination of EN with PN group. Results Among three groups, the ventilator weaning time had no significant differenceand the nutritional effect was similar;PN group and the combined group reached nitro-gen balance more rapidly. The gastrointestinal tract complications were less in PN group and combined group than those in EN group. When compared with the cost of three groups, EN group was the cheapest. Additionally, the immunological index of combined group was the highest. Conclusion The patients with MV generally have dystrophy and nutrition can be supported by enteral, parenteral or both. EN is cheap and convenient;it has advantage in recovery of gastrointestinal function, but the effect intotal PN group is definite and rapid. Therefore,combiningboth can mutually benefit each other.
