Abstract
PURPOSE OF REVIEW This review aims to summarize recent studies that highlight the complex relationship between nutrition, carbohydrate, insulin provision and glycaemic control in the critically ill patient population. RECENT FINDINGS Results of observational studies concur to support early hypoglycaemia and persisting hyperglycaemia as life-threatening events. In contrast, interventional studies indicate that early macronutrient restriction appears to reduce the benefits related to insulin therapy. This restriction is however associated with improved outcomes in itself. The potential role of modified enteral solutions as an adjunctive treatment to attenuate hyperglycaemia warrants further research. The selection of a therapeutic modality may also differ according to the characteristics of the setting, such as the nurse-to-patient ratio, the type and accuracy of meters, including near-continuous glucose monitoring and the availability of computer-guided protocols. SUMMARY There appears to be significant interplay between nutrition, including carbohydrate provision, blood glucose control and clinical outcomes. Individualized care is probably needed to define the optimal glucose target and nutritional intervention. This can differ according to the preexistence of chronic hyperglycaemia, the timing from the onset of critical illness and the clinical condition itself.

Shen Y, Qiu B, Ge Q, Hu L, Cong Z, Wu Y. Effect of early enteral nutrition on short-term outcomes and survival in patients in the cardiothoracic intensive care unit: An inverse probability weighted retrospective study. Nutrition 2024; 119:112328. [PMID: 38237353 DOI: 10.1016/j.nut.2023.112328] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 11/15/2023] [Accepted: 12/09/2023] [Indexed: 02/12/2024]
Abstract
OBJECTIVES The merits of early enteral nutrition (EEN) in patients in the cardiothoracic intensive care unit (CTICU) remain unclear. This retrospective study aimed to address this issue. METHODS We analyzed data from the MIMIC IV v2.0 database, including patients with a CTICU stay of ≥4 d. Patients were divided into early and delayed enteral nutrition (EN) groups. Differences in baseline data were corrected using an inverse probability weighting (IPW) approach. Generalized linear models (GLMs) were used to compare trends over time between groups, and survival effects were evaluated with weighted logistic and Cox regression, supplemented by weighted Kaplan-Meier curves. Subgroup analysis facilitated the exploration of potential interactions. RESULTS The study included 720 CTICU patients. Following IPW, all baseline variables were balanced. EEN led to shorter hospital and CTICU stays, lower incidence of respiratory and blood infections, and reduced total insulin usage in the first week of CTICU admission, albeit with an increased total gastric residual volume. Mortality risk between the groups did not significantly differ at 28 d or at 1 y. Excessive early energy and protein intake elevated the risk of 28-d mortality, but the relationship may not be linear. Overweight patients or those with fewer comorbidities had a higher mortality risk with EEN. CONCLUSIONS EEN may improve short-term outcomes in CTICU patients without a clear survival benefit. Early high caloric and protein intake could lead to adverse outcomes, suggesting a careful evaluation for initiating EN in specific patients.

Yue HY, Peng W, Zeng J, Zhang Y, Wang Y, Jiang H. Efficacy of permissive underfeeding for critically ill patients: an updated systematic review and trial sequential meta-analysis. J Intensive Care 2024; 12:4. [PMID: 38254228 PMCID: PMC10804832 DOI: 10.1186/s40560-024-00717-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Accepted: 01/17/2024] [Indexed: 01/24/2024] Open
Abstract
BACKGROUND Our previous study in 2011 concluded that permissive underfeeding may improve outcomes in patients receiving parenteral nutrition therapy. This conclusion was tentative, given the small sample size. We conducted the present systematic review and trial sequential meta-analysis to update the status of permissive underfeeding in patients who were admitted to the intensive care unit (ICU). METHODS Seven databases were searched: PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, Chinese Biomedical Literature Database, and Cochrane Library. Randomized controlled trials (RCTs) were included. The Revised Cochrane risk-of-bias tool (ROB 2) was used to assess the risk of bias in the enrolled trials. RevMan software was used for data synthesis. Trial sequential analyses (TSA) of overall and ICU mortalities were performed. RESULTS Twenty-three RCTs involving 11,444 critically ill patients were included. There were no significant differences in overall mortality, hospital mortality, length of hospital stays, and incidence of overall infection. Compared with the control group, permissive underfeeding significantly reduced ICU mortality (risk ratio [RR] = 0.90; 95% confidence interval [CI], [0.81, 0.99]; P = 0.02; I2 = 0%), and the incidence of gastrointestinal adverse events decreased (RR = 0.79; 95% CI, [0.69, 0.90]; P = 0.0003; I2 = 56%). Furthermore, mechanical ventilation duration was reduced (mean difference (MD) = - 1.85 days; 95% CI, [- 3.44, - 0.27]; P = 0.02; I2 = 0%). CONCLUSIONS Permissive underfeeding may reduce ICU mortality in critically ill patients and help to shorten mechanical ventilation duration, but the overall mortality is not improved. Owing to the sample size and patient heterogeneity, the conclusions still need to be verified by well-designed, large-scale RCTs. Trial Registration The protocol for our meta-analysis and systematic review was registered and recorded in PROSPERO (registration no. CRD42023451308). Registered 14 August 2023.
