OBJECTIVE： To discuss the effect of recombinant human growth hormone （HGH） on serum sndotoxin， inflammatory cytokines， wound healing time， hospitalization time and prognosis of elderly patients with severe burn. METHODS： 96 elderly patients with severe burn in our hospital were randomly divided into treatment group （48 cases） and control group （48 cases）. All patients received wound surface care， nutritional support， maintaining water and electrolyte and acid-base balance. Control group received 1 ml 0.9％ Sodium chloride solution， sc， qd. Treatment group received 0.3 IU/kg. Recombinant HGH for injection， sc，qd. All patients were treated for 21 d. Serum endotoxin content in 2 groups before and 14， 21 d after treatment was compared， inflammatory cytokines （TNF-α， IL-6，  IL-8） before and after treatment， wound healing time， hospitalization time and the incidence of multiple organ disorder syndrome （MODS）， death and systemic infection were observed. RESULTS： There was no significant difference in serum endotoxin content before and 14 d after treatment（P＞0.05）； after 21 d， serum endotoxin contents in 2 group obviously decreased， and treatment group was significantly lower than control group，with statistical significance （P＜0.05）. After treatment， IL-8 level in treatment group was significantly higher than control group， TNF-α and IL-6 were significantly lower than control group， with statistical significances （P＜0.05）. Wound healing time and hospitalization time in treatment group were significantly shorten than control group， with statistical significances （P＜0.05）. The incidence of MODS， death and systemic infection in treatment group were significantly lower than control group， with statistical significances （P＜0.05）. CONCLUSIONS： The application of recombinant HGH in elderly patients with severe burn can reduce toxins absorption of patients and decrease inflammatory cytokines to promote wound healing and improve prognosis.
