Growing use of home enteral nutrition: a great tool in nutrition practice toolbox

PURPOSE OF REVIEW

Home enteral nutrition (HEN) is a well-established practical nutrition therapy tool that is typically managed by an interdisciplinary team. Prevalence of HEN is increasing across the globe given significant evidence for utility, feasibility, efficacy, safety, and reliability of HEN in helping patients meeting their nutrition needs. The current review highlights the growing use of HEN in the context of what is novel in the field including trends in HEN practice with regards to tubes and connectors, feeding formula and real food blends, and common complications. The review also highlights that the use of HEN is expected to expand further over coming years emphasizing the need for national consensus recommendations and guidelines for HEN management.

RECENT FINDINGS

The growing use of HEN has always been parallel to adoption of holistic definitions and concept of malnutrition in clinical nutrition practice and more understanding of the need for malnutrition risk stratification, meeting unmet needs in practice and addressing challenges that lead to suboptimal enteral nutrition.

SUMMARY

Research and advancements in technology as well as in tube feeding formula industry have led to the development of more solutions and have helped identify and implement best HEN practices.

Impact of Enteral Feeding on Vasoactive Support in Septic Shock: A Retrospective Observational Study

BACKGROUND

Introducing enteral nutrition (EN) during hemodynamic instability may induce the splanchnic steal phenomenon, which may worsen systemic oxygen delivery and increase vasopressor dose. We aimed to determine the change in vasopressor dose in septic shock patients who received concomitant EN. We hypothesize that EN delivery is not associated with worsening hemodynamic instability, as defined by an increase in vasopressor dose ≥50% at 24 hours.

METHODS

This is a retrospective observational cohort study of adult patients with septic shock who were admitted to the intensive care unit from January 2015 to June 2015 and received EN. Vasopressor and EN parameters were collected at 6-hour intervals for the first 24 hours.

RESULTS

Data were available for 28 consecutive patients. The mean age was 60 years (SD = 18), and 54% were females. Norepinephrine (NE) was used in 100%. EN and vasopressor overlap totaled 36 hours (interquartile range [IQR], 27-69). Median NE dose when starting EN was 5.9 μg/min (IQR, 3.88). Median change in dose from 0 to 6 hours was 0.85 μg/min (95% CI, 0.681.06; P = 0.136), corresponding to a median increase of 14.5%. Total NE duration was 60.5 hours (IQR, 47.5-75.5). No serious complications occurred.

CONCLUSION

The median vasopressor dose did not increase by ≥50% during the first 24 hours of EN. This suggests early EN delivered during septic shock is not associated with worsening hemodynamic instability. Limitations include a small sample size and residual confounding. Prospective data are needed.
