Predicting enteral feeding intolerance in patients with sepsis: Why and how?

Clinical effects and safety of semi-solid feeds in tube-fed patients: a meta-analysis and systematic review

Background

Enteral nutrition is a very important form of treatment for critically ill patients. This meta-analysis aimed to evaluate the clinical effects and safety of semi-solid feeds in tube-fed patients.

Methods

Two researchers searched PubMed, clinical trials, Embase, Cochrane Central Register of Controlled Trials, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data, and Weipu databases for randomized controlled trials (RCTs) on the clinical effects and safety of semi-solid feeds in tube-fed patients until 10 October 2023. The quality evaluation tool recommended by the Cochrane Library was used to evaluate the quality of included RCTs. RevMan 5.4 software was used for data analysis.

Results

A total of eight RCTs involving 823 tube-fed patients were included in this meta-analysis. A synthesized outcome indicated that semi-solid feeds reduced the incidence of diarrhea (RR = 0.32, 95%CI:0.20-0.50, P < 0.001), vomiting (RR = 0.31, 95%CI:0.15-0.64, P = 0.002), abdominal distension (RR = 0.41, 95%CI:0.22-0.76, P = 0.005), length of intensive care unit (ICU) stay (MD = -3.61, 95%CI: -6.74 to -0.48, P = 0.02), and length of hospital stay (MD = -7.14, 95%CI: -10.31 to -3.97, P < 0.01) in tube-fed patients. Enteric feeding had no effect on the 30-day mortality (RR = 0.55, 95%CI: 0.19-1.56, P = 0.26). No publication bias was detected by the Egger's test results (all P > 0.05).

Conclusion

Semi-solid feeds are beneficial in reducing the incidence of diarrhea, abdominal distension, vomiting, and hospital stay. More high-quality studies are needed in the future to verify the effects of semi-solid feeds on mortality.

Improving enteral nutrition tolerance and protein intake maybe beneficial to intensive care unit patients

Enteral nutrition (EN) is important for critically ill patients. This study investigated the current situation of EN treatment in SHANGHAI intensive care units (ICUs). We hypothesized that improving EN practice in SHANGHAI may benefit the prognosis of ICU patients. Clinical information on EN use was collected using clinic information forms in 2019. The collected data included the patient's general clinical information, EN prescription status, EN tolerance status, and clinical outcomes. The observation time points were days 1, 3, and 7 after starting EN. A total of 491 patients were included. The proportion of EN intolerance (defined as < 20 kcal/kg/day) decreased, with rates of intolerance of 100%, 82.07%, 70.61%, and 52.23% at 1, 3, 7, and 14 days, respectively. Age, mNutric score, and protein intake < 0.5 g/kg/day on day 7 were risk factors for 28-day mortality.The EN tolerance on day 7 and protein intake > 0.5 g/kg/day on day 3 or day 7 might affect the 28-day mortality. Risk factors with EN tolerance on day 7 by logistic regression showed that the AGI grade on day 1 was a major factor against EN tolerance. The proportion of EN tolerance in SHANGHAI ICU patients was low. Achieving tolerance on day 7 after the start of EN is a protective factor for 28-day survival. Improving EN tolerance and protein intake maybe beneficial for ICU patients.
