title: [Influence of resting the digestive duct in gastric emptying. Comparison of 2 nutritional modalities: glucidic enteral and total parenteral nutrition].
abstract: Gastrointestinal motility is altered in several clinical situations in which Total Parenteral Nutrition (TPN) is indicated. Nevertheless, the effects of TPN on motility are not well known. In this study, Wistar rats (250-280 g) were divided into two groups were defined according to the route of administration of the nutrients: Group A (with TPN: 100% of the total non-protein calories administered as glucose), and Group B (solid enteral nutrition, but with the infusion of normal saline under the same conditions as in the previous group). Each group was subjected to three different infusion times: 24 hours, 3 days, and 5 days post-intervention, after which the gastric emptying was measured by means of the phenol red test. TPN delayed emptying in all the times with respect to group B, although significant differences were only found after 3 days of infusion.
