A written informed consent will be taken from the patients or their relatives. Patients will be randomly assigned to receive standard enteral nutrition plus 100 ml/day 0.9% normal saline at a rate 12.5 ml/h over 8 h for 5 days as the control group (Group C) or intravenous fish-oil-based lipid (SMOF lipid 20% which contains a unique 4-oil mix containing Soya bean, Medium-chain triglycerides, Olive oil and Fish oil) (Fresenius Kabi, Bad Homburg, Germany) emulsion supplementation to standard enteral nutrition (group L) in a dose of 100 ml/day at a rate of 12.5 ml/h over 8 h daily for 5 days.Finally, 20 mL of 0.9% normal saline was injected into the burette to flush the system. The entire apparatus was disposed of when each infusion was completed. The whole process was repeated for each infusion.
Investigators suggest that early administration of intravenous lipid emulsion (ILE) affect the inflammatory response and improve outcome in COVID-19. The aim of this trial is to study the effect of fish-oil-based intravenous lipid emulsion (FOBLE) supplementation added to enteral nutrition on shift to ICU for upgrading oxygenation &/or ventilation in moderate cases of Covid-19 diseased patients requiring only supplemental oxygen in form of simple nasal cannula or venturi mask oxygen (during 7 days admission).
