Glutamine regulates many biological functions in preserving the cell, acts as a key respiratory fuel and nitrogen donor for rapidly dividing cells, and modulates the expression of many genes associated with metabolism, cell defences and repair, and cytokine production. In severe thoracic trauma, glutamine supplementation is essential because the body consumes more than it produces and glutamine effects become dependent on its route of delivery.
Fifty-two patients 19 to 78 years old with surgery for severe thoracic trauma were assessed in two groups: Group A received 0.3 to 0.5 g/kg/day i.v. glutamine + 20 g enteral glutamine for 7 days, supplementation to enteral nutrition; Group B receive only i.v. glutamine supplementation to enteral nutrition 0.3 to 0.5 g/kg/day for 7 days. Weaning time, the duration of p.o. ileus, incidence and time to resolution of VAP, glycemic level and the percentage decrease of CRP at 96 hours were assessed in both groups.
Glutamine becomes an essential amino acid in severe thoracic trauma and when the patients are fed other than TPN (enteral, oral); although hard evidence is lacking, both administration routes may be efficient as soon as possible.
