The provision of nutrition to critically ill patients in the ICU often receives lower priority compared with hemodynamic and ventilation control. This frequently results in a significant calorie deficit. Overestimation of daily energy expenditure may also result in adverse outcomes. In many centers, nutritional decision making is based on predictive formulas, which have been shown to underestimate true energy requirements. Such estimations are ideally performed using indirect calorimetry. Nevertheless, the use of indirect calorimetry has been limited owing to costs and technical difficulties. Controversies about its actual clinical benefits are the focus of recent clinical studies and recommendations. The aim of this review was to describe the advantages of measuring indirect calorimetry within the concept of energy-protein goal-oriented therapy.
与血流动力学和通气控制相比，重症监护病房（ICU）中危重症患者的营养供给通常优先级较低。这通常会导致明显的热量不足。对每日能量消耗的高估也可能导致不良后果。在许多中心，营养决策是基于预测公式做出的，这些公式已被证明会低估真实的能量需求。使用间接测热法可以对其进行理想的估计。然而，由于成本和技术困难，间接测热法的使用受到限制。最近的临床研究和建议关注的是其实际临床获益的争议。本综述的目的是描述在能量-蛋白质目标导向治疗概念中测量间接测热法的优势。
