严重烧伤患者核黄素营养状况的分析

Analysis of riboflavin status in severely burned patients

目的 了解严重烧伤患者核黄素的营养状况。 方法 用登记加询问核实法统计分析 32例严重烧伤患者 [烧伤面积 ( 30 .2± 10 .9) % ,平均烧伤指数 19.7]伤后 37d、814d平均每日核黄素、蛋白质和热能经不同途径摄入量 ,并用荧光法测定 32例严重烧伤患者伤后 37d、814d核黄素 4h尿负荷试验。 结果 32例严重烧伤患者伤后 37d、814d平均每日摄入蛋白质和热能基本达我国烧伤患者热卡估算公式量 ,蛋白质摄入量约占总热量的 17% 18% ,平均每日摄入核黄素约 35mg ,而 4h尿负荷试验核黄素平均排出量均小于 40 0 μg。 结论 严重烧伤患者伤后

Objective To investigate riboflavin status in severely burned patients. Methods Thirty-two severely burned patients, with TBSA of (30.2±10.9)% and average burn index of 19.7, were enrolled in the study .The everyday intake amounts of riboflavin, protein and calorie via different routes by each patient were recorded. Fluorescence method was employed to detect 4 hour urine load test in the patients after oral taking of riboflavin on 3~7 and 8~14 postburn days (PBDs). Results The averaged everyday intake amounts of protein and calorie by each patient in this study on 3~7 and 8~14 PBDs reached the requirement of Chinese burn patients' nutritional supplying formula. And protein administration occupied 17%~18% of total calorie. The averaged everyday intake of riboflavin by each patient was 3~5 mg. But it was exhibited in 4 hour urine load test that average urine discharging amount of riboflavin were all less than 400 μg. Conclusion There existed obvious systemic deficiency of riboflavin during 3~14 PBDs in severely burned patients.
