Metabolic support in the critically ill: a consensus of 19.

ABSTRACT: Metabolic alterations in the critically ill have been studied for more than a century, but the heterogeneity of the critically ill patient population, the varying duration and severity of the acute phase of illness, and the many confounding factors have hindered progress in the field. These factors may explain why management of metabolic alterations and related conditions in critically ill patients has for many years been guided by recommendations based essentially on expert opinion. Over the last decade, a number of randomized controlled trials have been conducted, providing us with important population-level evidence that refutes several longstanding paradigms. However, between-patient variation means there is still substantial uncertainty when translating population-level evidence to individuals. A cornerstone of metabolic care is nutrition, for which there is a multifold of published guidelines that agree on many issues but disagree on others. Using a series of nine questions, we provide a review of the latest data in this field and a background to promote efforts to address the need for international consistency in recommendations related to the metabolic care of the critically ill patient. Our purpose is not to replace existing guidelines, but to comment on differences and add perspective.

Project description:BackgroundCoronavirus disease 2019 (COVID-19) is an ongoing public health crisis that has led to many deaths due to multiple organ dysfunction syndromes (MODS). This article describes the clinical characteristics, management, and outcomes of critically ill COVID-19 patients who survived the disease through mechanical circulatory support (MCS).MethodsWe studied 25 critically ill COVID-19 patients who underwent MCS from January 20, 2020, to April 10, 2020, at the Tongji Hospital of Huazhong University of Science and Technology.ResultsThirteen (52%) of the 25 patients survived with MCS support, while 12 (48%) died. At the time of their hospital admission, we identified significant differences in their peak cardiac troponin I (cTnI) and interleukin 6 (IL-6) levels, as well as in their lymphocyte count and C-reactive protein (CRP) levels. Cox proportional hazards regression model revealed that receipt of renal replacement therapy (RRT) was associated with an approximately 20-fold improvement in survival [hazard ratio (HR) =0.049, 95% confidence interval (CI) =0.008 to 0.305]. The number of days spent on extracorporeal membrane oxygenation (ECMO) support and the use of hydrogen (pH) at the time of MCS was also associated with an increase in survival. This contrasted with high-sensitivity C-reactive proteins (hs-CRP) and lactate, associated with a decrease in survival during MCS. Further analysis of the determinants relating to a COVID-19 patient's chance of survival on/after MCS was also indicated by levels of IL-6 (β=0.009, P=0.006), IL-8 (β=0.031, P=0.020), and TNF-α (β=0.107, P=0.014), which saw a significant increase in the 12 patients who died. This contrasts with the non-significant decrease in IL-6, IL-8, and TNF-α levels in the 13 patients who survived.ConclusionsThese results indicate that pH, lactate, hs-CRP, ECMO duration, and RRT are important clinical determinants for assessing how MCS can increase the chances of critically ill COVID-19 patients surviving the disease.

Project description:BackgroundLittle is known about metabolic and nutrition characteristics of patients with coronavirus disease 2019 (COVID-19) and persistent critical illness. We aimed to compare those characteristics in patients with PCI and COVID-19 and patients without COVID-19 infection (non-CO)-primarily, their energy balance.MethodsThis is a prospective observational study including two consecutive cohorts, defined as needing intubation for >10 days. We collected demographic data, severity scores, nutrition variables, length of stay, and mortality.ResultsAltogether, 104 patients (52 per group) were included (59 ± 14 years old [mean ± SD], 75% men) between July 2019 and May 2020. SAPSII, Nutrition Risk Screening (NRS) score, proportion of obese patients, duration of intubation (18.2 ± 11.7 days), and mortality rates were similar. Patients with COVID-19 (vs non-CO) had lower SOFA scores (P = 0.013) and more frequently needed prone position (P < 0.0001) and neuromuscular blockade (P < 0.0001): lengths of ICU (P = 0.03) and hospital stays were shorter (P < 0.0001). Prescribed energy targets were below those of the ICU protocol. The energy balance of patients with COVID-19 was significantly more negative after day 10. Enteral nutrition (EN) started earlier (P < 0.0001). During the first 10 days, COVID-19 patients received more lipid (propofol sedation) and less protein. Higher admission C-reactive protein (P = 0.002) decreased faster (P < 0.001). Whereas intestinal function was characterized by constipation in both groups during the first 10 days, diarrhea was less common in patients with COVID-19 thereafter.ConclusionCompared with non-CO patients, COVID-19 patients were not more obese, had lower SOFA scores, and were fed more rapidly with EN, because of a more normal gastrointestinal function possibly due to fewer non-respiratory organ failures: their energy balances were more negative after the first 10 days. Propofol sedation reduced protein delivery.
