Influence of Nutrition on Lung Microbiota in Traumatic Brain Injury

Lung Microbiota in Traumatic Brain Injury

Role of immunonutrition in modulating the lung microbiota of intubated TBJ patients and how this interaction may affect the infections and outcomes.

For these reasons, the aims of our study are the evaluation of the impact of immunonutrition on the lung microbiota and the relationship between lung microbiota and infection in TBJ patients in ICU.

Traumatic brain injury patients, requiring mechanical ventilation admitted to ICU will be randomly divide in two groups receiving standard nutrition or specialized formula.

Lower lavage (Bronco Alveolar Lavage: BAL) samples will be collected at admission in ICU and at day 7 for the microbiota analysis. Clinical follow-up at day 28 will be obtained
