重型脑外伤早期患者氮平衡改变与营养

The nitrogen balance change and nutrition sustain treatment on patients with early severe head injury

目的 研究重型脑外伤早期昏迷患者的氮平衡改变及营养支持治疗 ,降低患者的病死率和病残率 ,提高患者的生存质量。方法 观察治疗 78例重型脑外伤后 10天内的排氮量 ,分析排氮量与病情和体重之间的关系 ,同时予以胃肠道内或胃肠道外营养补充。结果 患者脑外伤后平均每日排氮量 18g( 8～ 4 4 g) ,10天内患者负氮平衡总量 5 8g( 2 8～ 10 8g) ,体重平均减少 4 7kg( 2 5～6 0kg)。 结论 选择适当与合理的营养补充途径和适量的补充蛋白质、微量元素。

Objective To study the nitrogen balance change and nutrition sustain treatment on early severe head injury, so as to lower the deformity and mortality rate and improve the survival quality of the patients.Methods The nitrogen balance change was observed on 78 cases of severe head in jury within 10 days,and the relationship between nitrogen quantity excreted and the state of illness was analysed while early nutrition supplement was administered via enteral and parenteral route. Results The patients average nitrogen exclude quantity is 18g(8～44g),the gross quantity of negative nitrogen balance is 58g(28～108g),the average body weight reduction is 4 7kg(2 5～6 0kg).Conclusion Adequate and reasonable nutrition sustain is an effective way to lower the deformity and mortality rate for severe head injury patients.
