Health through nutrition & lifestyle
Why is malnutrition important to consider?
Many patients who fall into the at-risk group (incl. older people) and have been advised to follow stay at home, are also those considered to be at greater risk of malnutrition. Malnutrition is a serious condition which can increase a person’s risk of infection as well as slowing down their recovery:

Are mechanically ventilated patients at high risk of malnutrition in the longer term?
Yes, it is well recognised that mechanically ventilated patients have severe catabolic muscle wasting (approximately 30% in 20 days) and poor long term outcomes (Herridge). It is also well recognised that patients being mechanically ventilated for longer period, on removal of ventilatory support struggle to increase their oral intake (Peterson 2010) and often need ongoing intensive nutrition support to meet their elevated requirements during recovery (Lambeth 2020, Ridley 2019).

What kind of nutritional support is preferred for critically ill COVID-19 patients?
General recommendations for critically ill patients, The majority of the guidelines from medical societies are recommending early commencement and buildup of enteral nutrition and that this is best practice for critically ill and acute respiratory distress syndrome (ARDS) patients. There are some concerns about early supplementary parenteral nutrition (PN) commencement and the use of supplementary PN with extracorporeal membrane oxygenation (ECMO) patients. However if nasogastric (NG) feeding causes persistent intolerance, and nasojejunal (NJ) feeding is not possible, it may be preferable to ensure these patients are fed with more specialised/hydrolysed feeds or PN.

What is the energy and protein requirement of critically ill COVID-19 patients?
Nutritional and Critical Care Societies do not give specific nutritional recommendations for COVID-19 patients. Therefore general recommendations for critically ill patients
- Energy requirement: the internationally widely used recommendation of 25-30 kcal per kg body weight of energy is recommended.
- Protein requirement: 1.2-2.0 g / kg of protein is recommended.
It is also generally recommended to administer enteral nutrition slowly to a uniform speed. For patients staying in ICU long term (>3 days) it is important to monitor nutritional status and if possible and required based on patients’ needs support with (enteral) nutrition.
