“…Twelve of the aSAH patients in this study (30%) experienced a temperature > 38 • C within 24 h prior to IC. As these patient populations experience changes in metabolic function, performing IC may also reveal useful metabolic information that might be translated into clinical information and have the potential to serve as both prognostic indicators or treatment targets (27).…”

Energy Expenditure in Critically Ill Adult Patients With Acute Brain Injury: Indirect Calorimetry vs. Predictive Equations

Introduction: Predictive equations (PE) are used in lieu of indirect calorimetry (IC) due to cost and limited resources; however, these equations may not be as accurate as IC in estimating resting energy expenditure (REE) in critically ill patients, putting them at risk of malnutrition. The purpose of this study is to compare predicted and measured energy expenditure (MEE) in critically ill adults with acute brain injury. Materials and Methods: This was a retrospective review of adult patients admitted to the Neurosciences ICU with acute brain injury between May 1st, 2014 and April 1st, 2016 who had IC performed. The Harris Benedict (HBE), Penn State University, and Mifflin St Jeor (MSJ) PE were used in comparison to IC results. Subgroup analyses stratified patients based on BMI and type of acute brain injury. Results: One hundred and forty-four patients met inclusion criteria. Comparing predicted and MEE found no significant difference (p = 0.1). High degrees of interpatient variability were discovered, with standard deviations ranging from 17 to 29% of each PE. Pearson's correlations indicated weak associations when HBE, Penn State, and MSJ were individually compared to MEE (r = 0.372, 0.409, and 0.372, respectively). A significant difference was found between predicted and MEE in patients with a BMI < 30 kg/m 2 (p < 0.01) and in those with aneurysmal subarachnoid hemorrhage (p < 0.01). Discussion: Due to interpatient variability that exists among REE of critically ill patients with acute brain injury, IC should be used when feasible.

“…Metabolic responses to shock and injury were first described by Sir Cuthbertson [15]. According to his investigations, there is a short ebb phase starting immediately after a traumatic shock and followed by a flow phase of longer duration after 3 to 10 days (Figure 2) [16]. The ebb phase is characterized by a decrease in metabolic rate, oxygen consumption, body temperature, and enzymatic activity.…”

“…Similarly, post-burn hypermetabolism was shown to increase REE as high as 100% above normal as consequence of a strong catabolic response mediated by endogenous catecholamines and inflammatory cytokines. Nevertheless, this hypermetabolic state is a direct effect of burn trauma, its persistence leads to severe septic complications, multiple organ failure, and higher mortality [16]. Nutritional follow up in burn patients shows a highly dynamic and variable REE up to 160 days after injury (Figure 3) [32].…”

Indirect calorimetry (IC) is considered as the gold standard to determine energy expenditure, by measuring pulmonary gas exchanges. It is a non-invasive technique that allows clinicians to personalize the prescription of nutrition support to the metabolic needs and promote a better clinical outcome. Recent technical developments allow accurate and easy IC measurements in spontaneously breathing patients as well as in those on mechanical ventilation. The implementation of IC in clinical routine should be promoted in order to optimize the cost–benefit balance of nutrition therapy. This review aims at summarizing the latest innovations of IC as well as the clinical indications, benefits, and limitations.

“…Rattanachaiwong & Singer (4) realizaron una revisión narrativa sobre la utilidad que puede tener la CI con una Prueba en el Sitio de Atención (Point of Care Testing o POCT). Una POCT es una prueba de diagnóstico clínico aplicado en el lecho del paciente cuyos resultados afectan la toma de decisiones terapéuticas de manera rápida; por ejemplo, la pulsioximetría, la capnografía, y la glucometría, entre otras.…”

“…Actualmente se recomienda la práctica de una medicina dirigida a objetivos puntuales y a su vez personalizada o individualizada (1)(2)(3) . Además, cada vez es más factible disponer de instrumentos de apoyo clínico que se pueden utilizar en la cabecera del paciente y que nos permite la toma de decisiones inmediatas para el ajuste de nuestro tratamiento (POCT: Point of care testing) (4) .…”
