Define Initial Phase for nutritional treatment of neuro trauma patients?

In this, the life threatening conditions need to be controlled first.  Soon the nutritional support must start because hyper metabolism contributes lo excess energy expenditure and hyper metabolism to increased protein demand.  This increased energy (1.75 x 2 x BEE) and protein demand (1.5-2.5 g/ kg IBW) must be met initially via nutritional support methods or enteral/parenteral, nutrition. If nutritional replacement is not provided, 10% decrease in lean body mass can occur within in a week, with up to 30% loss in two to three weeks. This is associated with increased mortality.
