[Analysis of riboflavin status in severely burned patients]
1Department of Burns and Plastic Surgery, The First Central Hospital of Tianjin 300192, P.R. China.
Objective:
To investigate riboflavin status in severely burned patients.
Methods:
Thirty-two severely burned patients were enrolled in the study with TBSA of 30.2 plus minus 10.9% and average burn index of 19.7. 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 32 patients after oral taking of riboflavin on 3 similar 7 and 8 similar 14 postburn day (PBD).
Results:
The averaged everyday intake amounts of protein and calorie by each patient in this study on 3 similar 7 and 8 similar 14 PBDs reached the requirement of Chinese burn patients' nutritional supplying formula. And protein administration occupied 17% similar 18% of total calorie. The averaged everyday intake of riboflavin by each patient was 3 similar 5 mg. But 4 hour urine load test exhibited that average urine discharging amount of riboflavin was all less than 400 microgram.
Conclusion:
There existed obvious systemic deficiency of riboflavin on 3 similar 14 PBD in severely burned patients.
