Following severe trauma and surgical injury, nutritional support via the enteral route has been shown to lead to increased survival and decreased complications when compared to the parenteral route. We hypothesized that the route of nutrient delivery may affect cutaneous wound healing following severe traumatic insult. Forty-six Sprague Dawley rats underwent bilateral closed femoral fractures, central venous catheterization, gastrostomy placement and dorsal skin incision with placement of polyvinyl alcohol sponges into subcutaneous pockets. Identical nutritional infusates of 25% dextrose, 4.25% amino acids, and vitamins were given, half the animals receiving the infusion via the gastrostomy (ENT) and the other half via the venous catheter (TPN). Animals were sacrificed on post-operative days 5, 7, or 10. Wound breaking strength (WBS, g) and sponge granuloma hydroxyproline content (OHP- a measure of wound collagen deposition, microg/ 100mg sponge) were measured. There were no significant nutritional differences between the two feeding groups. On days 5 and 7, WBS was significantly higher in the ENT group (58.0 +/- 3.1 g vs 48.9 +/- 2.6 g, p < 0.05, and 123 +/- 19 g vs 87.6 +/- 4.2 g, p < 0.05 vs TPN respectively). Sponge OHP content on day 5 was significantly higher in the ENT group (101 +/- 3 vs 86.7+/-5.8 microg/100 sponge, p < 0.05). These data demonstrate that the enteral feeding route imparts a benefit to early post-traumatic wound healing s compared to parenteral feeding.
