Changing of serum metabolic hormone and liver size during acute phase of severe adult burn patients.

The aims of this study were to determine characteristics and factors influencing metabolic hormones including serum catecholamines, cortisol level and liver size in severe adult burn patients. A prospective study was conducted on 44 adult burn patients with burn extent from and over 20% TBSA admitted during 72 h after burn to burn intensive care unit, National Burn Hospital, Vietnam. Serum levels of epinephrine, norepinephrine and cortisol were measured on admission and 7th day after burn. Liver size was measured by ultrasound on admission and 21st day after burn. The results indicated that norepinephrine level did not significantly change along the time meanwhile epinephrine concentration significantly increased after 1 week (P < 0.01). Serum cortisol level was higher than normal physiological value and then significantly reduced at 7th day post burn (P < 0.05). Significantly increased liver size was seen at the 21st day postburn (P < 0.01). Age, gender, burn severity, inhalation injury and death did not affect concentration of catecholamines and liver size. Meanwhile, cortisol level was significantly higher in patients with deep burn area ≥ 20% TBSA at 7th day after burn and in non-survivors (P < 0.05). Further studies are necessary to understand clearly metabolic state in severe adult burn patients. IJBT
