Review article: permissive underfeeding in short-term nutritional support
Alimentary Pharmacology & Therapeutics
|July 15, 2010
Summary
Permissive underfeeding, a nutritional strategy, may improve patient outcomes and reduce illness in those needing short-term nutritional support. This approach contrasts with traditional methods focused on exceeding energy and protein balance.
Area of Science:
- Clinical Nutrition
- Critical Care Medicine
- Medical Research Methodology
Background:
- Adequate nutritional support is crucial for specific patient populations.
- Traditional nutritional support aims to meet or exceed energy and protein balance.
- Permissive underfeeding has emerged as an alternative nutritional strategy.
Purpose of the Study:
- To evaluate the evidence supporting the benefits of permissive underfeeding.
- To assess the impact of permissive underfeeding in selected patient groups.
Main Methods:
- Systematic literature search of MEDLINE, Embase, PubMed, and Cochrane collaboration (1950-2010).
- Inclusion criteria applied to 591 initially identified abstracts.
- Independent review of remaining articles by two authors.
Main Results:
- Twelve studies were included in the final analysis.
- The included studies comprised 8 randomized interventional trials, 3 prospective cohort studies, and 1 retrospective analysis.
Conclusions:
- Permissive underfeeding may be linked to better patient outcomes.
- This nutritional strategy might reduce morbidity in patients requiring short-term nutritional support.

01:15Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

01:27Parentral Nutrition: Centeral and Peripheral Parental Nutrition
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
