[Urea production rate - a parameter of the catabolism in burns].

The Urea production (PU) of three severe burned patients is presented as an example for calculating protein loss. Burn injuries are accompanied by an extensive catabolism more then any other disease, operation or trauma. The operative stress caused a further increase of PU. The highest values are measured in electric burns. Alimentation is considered as an important therapeutic mean to diminish catabolism. Urea production rate is presented as a simple method to control protein loss and can be done in every hospital.
