A method of determining daily nitrogen requirements
  1. H. A. Lee,

    Abstract

    A simple formula for calculating daily nitrogen requirements and balance is presented. A close correlation was observed between calculated and actual nitrogen balance studies. For better precision a different correction factor is suggested for patients receiving protein hydrolysates and crystalline amino acid solutions. This formula will greatly aid those who have to devise complete intravenous nutrition regimes for patients whose condition varies daily. The biochemistry required for application of this formula is within the capacity of any small hospital laboratory.
