Effect of calories delivered on clinical outcomes in critically ill patients: Systemic review and meta-analysis

Abstract: Introduction:International guidelines are promoting early enteral nutrition (EN) as a means of feeding critically ill adult patients to improve clinical outcomes. The question of how much calorie intake is enough to improve the outcomes still remained inconclusive. Therefore, we carried out a meta-analysis to evaluate the effect of low calorie (LC) versus high calorie (HC) delivery on critically ill patients' outcomes.Methods:We included randomized clinical trials (RCTs) that compared LC EN with or without sup… Show more

“…Similarly, early studies of appropriate or hypocaloric provision were accompanied by low protein intakes. Also complicating the issue is that in several earlier studies, the included patients had normal nutritional status and therefore were unlikely to derive additional clinical benefit from increased nutritional intakes [89]. Thus, there is an unmet need for further research into the appropriate amount and timing of delivery of protein for acute care patients.…”

“…Obwohl qualitativ hochwertige Studien zur konkreten Beantwortung der Frage fehlen, hält die Leitliniengruppe eine "sollte"-Empfehlung für gerechtfertigt. In mehreren Metaanalysen konnte bei kritisch kranken Patienten keine Abhängigkeit der Effizienz einer bestimmten Ernährungstherapie vom BMI (als Surrogatparameter für den Ernährungszustand) gefunden werden [56,103,105]. Allerdings waren Patienten, die bereits vor der Homöostasestörung schwer mangelernährt waren (BMI < 18 kg/m 2 ), von den Studien ausgeschlossen.…”

“…In der chronischen Phase sollte die Protein-/Aminosäurenzufuhr bei 100 % des Ziels in der Akutphase (1 [56,103,105]. Allerdings waren Patienten, die bereits vor der Homöostasestörung schwer mangelernährt waren (BMI < 18 kg/m 2 ), von den Studien ausgeschlossen, und die Auswirkungen einer exklusiv erhöhten Proteinzufuhr wurden nicht untersucht.…”

“…Apesar do menor custo da dieta normocalórica normoproteica, deve-se considerar que nem sempre ela é suficiente para atender à demanda do paciente. Por outro lado, estudo de metanálise demonstrou que a oferta de alta caloria não trouxe melhores resultados quanto à mortalidade de doentes críticos (Chelkeba et al, 2017). Portanto, deve-se destacar que a escolha do tipo de dieta, de acordo com a densidade calórica e proteica, depende das necessidades de cada paciente, considerando o grau de desnutrição, sua patologia, plano terapêutico e melhores evidências científicas (Araújo-Junqueira & De-Souza, 2012;White et al, 2012).…”
