PARENTERAL NUTRITION IN CRITICAL CARE PATIENTS

Abstract

The nutritional delivery to critical care patients is challenging and may require justified 
evaluation of its composition. Parenteral nutrition (PN) is still inevitable in several situations. 
The nutritional support includes provision of calories, proteins, carbohydrates, lipids, 
micronutrients, electrolytes and fluids in appropriate amounts according to individual needs. We 
have reviewed the existing guidelines, meta-analysis studies, randomized controlled trials, and 
review articles for various components of PN and studied their impact on the clinical 
outcomes.We systematically searched PubMed, Medline and Embase for trials (published from 
2017 to 2020) investigating various components of parenteral nutrition and their impact on 
clinical outcomes. In conclusion, there is still lack of proper large scale trials to justify the 
optimal combinations with the dosage required of each component of PN.
