机械通气患者营养支持的应用

目的 比较肠外 肠内营养与肠内营养对施行机械通气的危重患影响。探讨对呼吸衰竭患如何给予合理的营养支持。方法 将40例机械通气患随机分为肠外 肠内营养A组（PN EN）和肠内营养B组（EN），同时进行营养状况评定。血气指标分析及血流动力学测定。结果　A组患早期换气及弥散功能均较B组轻度下降，但随着营养支持的继续，A组患全身营养状况及呼吸功能改善较B组明显，脱机时间缩短。血流动力学无明显变化。结论 对呼吸衰竭患行肠外 肠内营养有利于患恢复体重。提高免疫力，呼吸功能恢复快。

Nutritional Support in the Ventilatory Patients

Objective To evaluate the effects of different nutrition support mode on re spiration crock up patients.Methods Forty patients with artificial ventilation were randomized to PN+EN group (n=20)or EN group(n=20),the nutritio n status were assessed,artery blood gas analyzed and hemodynamics mensurated,a t the same time.Results No evident hemodynamic changes occurred in the both groups.Though group A patient gas exchange and dispersion function lightly des cended,but along with nutritional support hold on,group A patients' nutritio nal status and respiration function statistically improved to compare with group B.Online duration was shortened.Conclusions The respiration crock up patient s using PN+EN will be propitious to avoirdupois resuming,immunity advancing an d respiration function improving.
