Olive oil based nutrition in multiple trauma patients: a pilot study

Area of Science:

• Intensive Care Medicine
• Clinical Nutrition
• Metabolic Research

Background:

• Hyperglycemia is linked to poor outcomes in intensive care.
• The safety and efficacy of fat-based nutrition, particularly olive oil emulsions, remain under-investigated in surgical intensive care units.

Purpose of the Study:

• To evaluate the safety and clinical effects of a parenteral lipid-based nutrition regimen compared to a standard glucose-based regimen in severe multiple trauma patients.

Main Methods:

• Prospective, randomized, pilot study in a surgical intensive care unit.
• Thirty-three severe multiple trauma patients were randomized to receive either lipid-based (L group, n=18) or glucose-based (G group, n=15) parenteral nutrition.
• Key outcomes included energy expenditure, triglycerides, nitrogen balance, blood glucose, and clinical parameters like mechanical ventilation duration and ICU length of stay.

Main Results:

• No significant differences in energy expenditure, triglycerides, or nitrogen balance between groups.
• The lipid-based group (L group) demonstrated significantly lower blood glucose levels (7.4 vs. 8.7 mmol/l).
• The L group experienced shorter durations of mechanical ventilation (13.0 vs. 20.4 days) and ICU stay (17.9 vs. 25.1 days) compared to the G group.

Conclusions:

• Parenteral nutrition using olive oil-based emulsions is well-tolerated in intensive care.
• This fat-based regimen effectively reduces blood glucose levels.
• Olive oil-based nutrition leads to clinically significant reductions in mechanical ventilation duration and intensive care unit length of stay.
