2018年发表在《Crit Care》上的一项前瞻性、平行对照、II期先导研究,对危重患者的肠外营养(PN)的补充以及常规治疗的情况进行了比较。

背景:在危重病中,肠内营养(EN)的能量输送经常是不能满足所估计的能量需求的。PN作为EN的补充可能会增加能量输送。研究人员旨在确定同常规EN相比,入住ICU后个性化PN滴入补充48-72 h并维持最长7日是否能增加危重成年患者的能量输送。

方法:本研究是在澳州和新西兰的6家重症监护室所开展的一项前瞻性、平行对照、II期先导研究。至少有一个器官衰竭的机械通气患者且前24 h的EN输送低于能量需求估计的80%,接受PN策略(干预组)或常规EN。如果尝试使用常规方法优化输送后EN仍不足,常规治疗组EN可用PN进行补充。

结果:本研究纳入100名患者,其中99名纳入分析。总体上,71%的研究人群是男性,平均(SD)年龄是59(17)岁,急性生理学与慢性健康评估II评分为18.2(6.7)和体重指数为29.6(5.8) kg/m2。干预组从EN和/或PN输送的能量(平均(SD)1712(511)卡路里 vs 1130(601)卡路里,p<0.0001)以及占能量需求估算百分比(平均(SD)83(25)% vs 53(29)%,p<0.0001)都显着高于常规治疗组。并且干预组的蛋白输送和占蛋白需求估算的百分比(平均(SD)86(25)g,86(23)%)也高于常规治疗组(平均(SD)53(29)g,51(25)%,p<0.0001)。两组间的抗生素使用、入住ICU时长和住院时长、死亡率和功能性结局相似。

结论:同常规治疗能量输送相比,7日个性化PN滴入补充策略能显着改善能量输送。且两个患者组间的临床和功能结局相似。
