Emerging trends in nonvolitional nutrition support: the role of parenteral nutrition
Abstract Objective: To discuss of the role of parenteral nutrition (PN) support in the care of critically ill patients. Methods: Review of the literature. Results: Malnutrition is highly prevalent among hospitalized patients, with critically ill patients being at higher risk. To attenuate the complications experienced in this patient population, enteral nutrition (EN) and PN are used as nonvolitional nutrition support. Meta-analyses that compare EN with PN in critically ill patients show reduced infectious complications with EN. However, some evidence points to a mortality benefit for PN. Findings indicate that PN can be used as an adjunct to EN for improving nutritional delivery. Conclusion: Future studies are warranted to define the emerging role of PN in nutrition support.
