Abstract Background Burns are among the most devastating forms of injury. Nowadays the standard treatment for deep partial thickness and full-thickness burn is early excision and grafting, but this technique is not always feasible; and this leads to chronicity and microbial colonization of burn wounds. Interesting properties of human amniotic membrane made us use it in management of chronic infected burn wounds. Methods From January 2008 to September 2010, in a prospective clinical trail, 38 patients (76 limbs) with symmetric chronic burn wounds in both upper or lower limbs included in this study. Tissue cultures were taken from all the wounds. For the right, after debridement of granulation tissue and meshed split thickness skin grafting, the graft surfaces were covered with amniotic membrane dressing and in left limb wounds, after debridement, skin grafting was done in conventional method. 21 days later, the success rate of graft take was compared between two groups. Results The study group was composed of 76 limbs in 38 patients with mean age of 27.18 ± 6.38 and burn in 29.18 ± 7.23 TBSA%. The most common causes of the burn wounds chronicity in the selected patients was delayed admission due to poor compliance of the patients (44.8%). Staphylococcus was the most frequent isolate in wounds in our patients (62.85%). Mean graft take was observed in 90.13% of right upper limbs, and 67.36% of left upper limbs; which was significantly different ( P < 0.001). Conclusions Our study showed that human amniotic membrane dressing significantly increases the success rate of graft take in chronic wounds, and it can be recommended as an important dressing in chronic burn wounds management, due to interesting anti-microbial, and better graft take effects.
