The aim of the study was to assess thermogenesis during parenteral feeding (group A) and after an oral test meal of a polymeric diet (group B). Carbohydrates, fat and protein ratios in the oral meal and parenteral mixture were: 51:34:15 and 76:11:13, resp. In both situations 20% of resting energy expenditure (REE) was administered-as a bolus oral meal or during 120 min. of intravenous infusion. Mean results of respiratory gas exchange of 15 min. periods were used for calculations. Basal respiratory quotient (RQ) in group A and B was 0.841 and 0.806 resp (difference not significant; NS); peak RQ was 0.910 and 0.924 resp. (NS). Peak RQ in group B was significantly higher than basal (p < 0.006). REE in group A and B was 1,416 +/- 0,231 kj/kg/15 min. and 1,322 +/- 0,226 kj/kg/15 min. resp. (NS). Peak thermic effect (expressed as the rise of REE in percent of the energy content of the nutrients) was: 4.778% and 5.135% resp. (NS). Postprandial thermogenesis is not dependent on the route of administration of nutrients (parenteral or oral). The proportion of substrate utilisation depends on the content of the meal or parenteral mixture.
该研究的目的是评估肠外营养期间（A组）和食用聚合饮食口服试验餐之后（B组）的产热情况。口服餐和肠外营养混合物中的碳水化合物、脂肪和蛋白质比例分别为51:34:15和76:11:13。在两种情况下，均给予20%的静息能量消耗（REE）——作为口服推注餐或在120分钟静脉输注期间给予。使用15分钟时间段的呼吸气体交换平均结果进行计算。A组和B组的基础呼吸商（RQ）分别为0.841和0.806（差异不显著；NS）；峰值RQ分别为0.910和0.924（NS）。B组的峰值RQ显著高于基础值（p < 0.006）。A组和B组的REE分别为1,416 +/- 0,231千焦/千克/15分钟和1,322 +/- 0,226千焦/千克/15分钟（NS）。峰值热效应（以REE相对于营养素能量含量的百分比升高表示）分别为4.778%和5.135%（NS）。餐后产热不取决于营养物质的给药途径（肠外或口服）。底物利用比例取决于餐食或肠外营养混合物的成分。
