Brief summary
The purpose of this study is to determine the efficacy and safety of a diabetes-specific tube feed in comparison to an isocaloric, isonitrogenous standard enteral formula in critically ill patients receiving insulin treatment for blood glucose management.
Interventions
Continuous (24h) application according to a standardized enteral feeding protocol via nasogastric tube or percutaneous endoscopic gastrostomy (PEG); pump-assisted application (Charriére (CH) \> 8), duration according to patient's tolerance and requirements for a maximum of 5 days. Dosage: 21 - 24 kcal/kg body weight/day (corresponding to 14 to 16 ml/kg body weight/day).
