The debridement was applied in the first 96 h post-injury following the protocol suggested for Nexobrid~?. In patients with burns of more than 15% TBSA a second application of Nexobrid~? was performed. After the removal of the product-4 h post application and after a 2 h period of wet dressing-we used several products to cover the wound like Suprathel~?, Biobrane~?, Mepitel~? with wet dressing, silver sulphadiazine 1% cream, and in some cases even autografts. We treated patients with inhalation injury as well. All the procedures were done under deep sedation, regional blocks in extremities or general anaesthesia in the intensive care unit room or in the operating theatre.RESULTS After these first 25 cases, we have observed that patients with partial thickness burns treated with Nexobrid~?, experienced great benefits in the reduction of the need for autografting compared with the standard of care. This isbecause after selective enzymatic debriding of the burn scar we can distinguish different wound beds, which can coexist in the same patient, and we also managed to associate each one to its ability to epithelize. In major burns, besides the improvement in wound healing, we observed an important improvement in their general state. This may be because SIRS significantly improved through a bloodless debridement of necrotic tissue, decreasing the requirements of vasoactive drugs and fluid resuscitation. Circumferential burns also benefited from enzymatic debridement, observing a decrease in the number of compartment syndromes and the need for escharotomies. At present, we have not observed a positive effect in the evolution and outcome of major burns with inhalation injury.CONCLUSION The introduction of Nexobrid~? shows significant improvement in burn treatment. Cumulative experiences are necessary to adapt its application in all Burns Centres.展开更多

Current medical management uses various acellular dermal matrices on wound sites. The challenge for scientists is to examine, then to question accepted conventional wisdom and to present new concepts. In this paper, Autologous Cell Therapy will be described by using cell culture of autologous dermal fibroblasts and their extracellular matrix as a foundation for rebuilding the dermis in conditioned wound beds. This proposal seems to create a conflict with the medical approach to keeping a wound bed “moist”.展开更多
