全营养混合液在机械通气患者中的应用

TOTAL NUTRIENT ADMIXTURE USED FOR PATIENTS WITH MECHANICAL RESPIRATION

目的 通过营养支持,提高机械通气患者的脱机成功率。方法 对36例机械通气患者,同时采用全营养混合液支持,经右颈内静脉穿刺插管29例,股静脉7例,输注时间5～61d,平均19.2d。结果 经合理的TNA支持后,患者营养状况明显改善,增强了呼吸肌的作功能力,减少对呼吸机的依赖,提高了脱机成功率。36例中有31例1次脱机成功,2例2次脱机成功,1次脱机成功率达86.1%,总脱机成功率达91.7%。仅3例因MSOF而死亡。结论 TNA输注方便,安全。是机械通气患者摄取全营养和能量的理想方法。

Objective To improve the weaning rate of mechanical respirators through rational nutrient support.Method Total nutrient admixtures(TNA) were administered in 36 patients with mechanical respiration and the weaning rate of mechanical respirators was observed.Result After TNA,the nutrient state and function of respiratory muscles were significantly improved.The weaning of the respirator was successful at first try in 31 patients and at the second try in 2. The successful rate in the first try was 86.1% with total weaning rate 91.7%. 3 patients died of MSOF.Conclusion The administration of total nutrient admixtures is simple and safe,and is an ideal method for patients with mechanical respiration to intake nutrient and energy.
