Enteral nutrition is generally superior to total parenteral nutrition (TPN) for intensive care unit (ICU) patients. Evidence for special feeds and immunonutrients is lacking, and overfeeding should be avoided.

Area of Science:

  • Critical Care Medicine
  • Clinical Nutrition

Background:

  • Nutrition is vital for health, with widespread supplemental feeding in ICUs.
  • High-quality evidence guiding ICU nutritional practices is limited.
  • Enteral nutrition is the preferred route for most ICU patients.

Purpose of the Study:

  • To evaluate the evidence for different nutritional support strategies in the ICU.
  • To determine the efficacy of enteral nutrition versus TPN.
  • To assess the role of specialized nutritional formulas.

Main Methods:

  • Review of existing high-quality evidence on nutritional support in ICUs.
  • Comparison of outcomes between enteral nutrition and TPN.
  • Evaluation of studies on special feeds and immunonutrients.

Main Results:

  • Enteral nutrition is superior to TPN in most ICU scenarios.
  • Most ICU patients can be effectively managed with enteral nutrition.
  • Limited evidence supports the use of special feeds or immunonutrients.

Conclusions:

  • Enteral nutrition should be prioritized for ICU patients.
  • Current evidence does not strongly support specialized formulas.
  • Nutritional support should be carefully managed to avoid overfeeding and its adverse effects.
