Gastric versus transpyloric feeding in severe traumatic brain injury: a prospective, randomized trial.

PURPOSE: To evaluate the efficacy of transpyloric feeding (TPF) compared with gastric feeding (GF) with regard to the incidence of ventilator-associated pneumonia in severe traumatic brain injury patients (TBI).

DESIGN AND

SETTING

Prospective, open-label, randomized study in an intensive care unit of a university hospital.

PATIENTS: One hundred and four CHI adult patients admitted for TBI between April 2007 and December 2008. Patients were included within the first 24 h after ICU admission and were followed until discharge or 30 days after admission.

INTERVENTION: Patients were randomized to TPF or GF groups. They received the same diet, with 25 kcal kg(-1) day(-1) of calculated energy requirements and a nitrogen intake of 0.2 g N kg(-1) day(-1). Primary outcome was the incidence of early and ventilatory-associated pneumonia. Secondary outcomes were enteral nutrition-related gastrointestinal complications (GIC), days on mechanical ventilation, length of ICU stay and hospital stay, and sequential organ failure assessment score (SOFA).

RESULTS

The TPF group had a lower incidence of pneumonia, OR 0.3 (95% CI 0.1-0.7, P = 0.01). There were no significant differences in other nosocomial infections. The TPF group received higher amounts of diet compared to the GF group (92 vs. 84%, P < 0.01) and had lesser incidence of increased gastric residuals, OR 0.2 (95% CI 0.04-0.6, P = 0.003).

CONCLUSIONS

Enteral nutrition delivered through the transpyloric route reduces the incidence of overall and late pneumonia and improves nutritional efficacy in severe TBI patients.
