A retrospective study of urinary urea excretion has been performed in 91 burned patients. Maximum mean excretion occurred between days 5 and 8 after injury. The rate of excretion during this peak period correlated significantly with the sex and age of the patient as well as the burn size. It is suggested that peak nitrogen excretion may be more accurately predicted if all three variables are considered. However, the wide variation seen in patient response and differences in clinical management mean that regular measurement of urinary urea excretion still provides the most reliable guide to dietary protein requirements after a burn.
对91例烧伤患者进行了尿尿素排泄的回顾性研究。最大平均排泄量出现在受伤后第5天至第8天之间。在此高峰期的排泄率与患者的性别、年龄以及烧伤面积显著相关。建议如果考虑所有这三个变量，可能会更准确地预测氮排泄峰值。然而，患者反应的广泛差异以及临床管理的不同意味着定期测量尿尿素排泄仍然是烧伤后饮食蛋白质需求最可靠的指导。
