Accuracy of Urinary Urea Nitrogen for Predicting Total Urinary Nitrogen inThermally Injured Patients

摘要

Estimations of total urinary nitrogen from measured urinary urea nitrogen arecommonly used in calculating nitrogen balance. Recently published studies suggest the urinary urea nitrogen/total urinary nitrogen relationship is in constant and total urinary nitrogen must be directly measured in burned patients. This study addresses the relationship of urinary urea nitrogen to total urinary nitrogen after thermal injury. Two hundred random 24-hour urine collections obtained from
