Background and Goal of Study: The aim of this study is to compare gastric residuel volumes (GRV) and gastrointestinal complications in patients which enteral nutrition is started with formulas with and without fiber.
Materials and Methods: Sixty patients which were on mechanical ventilation, expected to stay more than 8 days in ICU and fed enterally with nasogastric tube were enrolled to the study. Patients with bowel obstruction, paralytic ileus, peritonitis, acute pancreatitis, inflammatory bowel diseases, bowel fistulas, gastrointestinal bleeding, short bowel syndrome, morbid obesity, gastrostomy or jejunostomy, nasogastric tube in ileum, patient-ventilator dyssyncrony, head trauma were excludued. Totally 60 patients were randomised into two study groups.
Without-fiber Group: was fed with standart isoosmolar formula (Osmolite, Abbott, Illinoisi USA), Fiber Group: was fed with standart isoosmolar fiber formula (Jevity, Zwolle, Holland)
Patients who reached targetted maximum calori value were monitored for 3 days. GRV‘s were measured 3 times a day. Gastrointestinal complications like abdominal distension, vomitting, regurgitation, aspiration, diarrhea episodes were registered.
Results and Discussion: For 3 day GRV‘s in Fiber Group were always larger than GRV‘s in Without-Fiber Group. But the difference was statistically insignificant. GRV‘s in none of the groups reached maximum acceptable level of 200 ml‘s.
Vomitting, regurgitation and distension were not different between groups. Diarrhea and aspiration were not observed in either groups. In twenty patients (66,66 %) in Fiber group and in seventeen patients (56,66 %) in WithoutFiber Group at least one complication was observed. The difference between groups was statistically insignificant.
Conclusion(s): As a conclusion, to start and continue the enteral nutrition with an enteral formula with fiber is as safe as to start and continue enteral nutrition with an enteral formula without fiber.
