In spite of recent progress in burn treatment, the early surgical therapy of partial thickness scald burns in children is still controversial. Early tangential excisions is not easily applicable for these patients because of difficulties in determination of the burn depth and probable physiological derangement after surgery. Hypertrophic scar formation and wound contraction after meshed autografts are other limitations. For these reasons, conservative treatment, not early excision therapy, has been chosen initially for these injuries. We used cultured epidermal allografts for extensive, partial thickness scald burns, during the early post-burn period without escharectomy. Fifty to 100% of the engrafted superficial dermal burns were epithelialized within 7 days. In contrast, untreated identical wounds remained open. Repeated grafting of cultured allografts on unexcised wound granulations of dermal burns also enhanced epithelialization. Long term results showed that hypertrophic scar formation in the mixed superficial and deep dermal burns was reduced when cultured allografts were used. Allografting of the cultured epidermis without surgical excision apparently promoted the rapid regeneration of the partial thickness burns. Procedural complications did not occur. Cultured allografts should be used as an effective and safe biological dressing for partial thickness scald burns in children.
尽管近年来烧伤治疗取得了进展,但儿童浅度烫伤的早期手术治疗仍存在争议。由于难以确定烧伤深度以及术后可能出现的生理紊乱,早期削痂术不易应用于这些患儿。网状自体皮移植后的瘢痕增生和创面挛缩是其他局限性。基于这些原因,对于这些损伤最初选择的是保守治疗而非早期切除治疗。我们在烧伤后早期未行焦痂切除的情况下,将培养的同种异体表皮用于大面积浅度烫伤。50%至100%移植的浅度真皮烧伤创面在7天内实现上皮化。相比之下,未治疗的相同创面仍未愈合。在未切除的真皮烧伤创面肉芽组织上反复移植培养的同种异体皮也促进了上皮化。长期结果表明,使用培养的同种异体皮时,混合性浅度和深度真皮烧伤的瘢痕增生减少。未进行手术切除而移植培养的表皮显然促进了浅度烧伤的快速再生。未发生手术并发症。培养的同种异体皮应用于儿童浅度烫伤时应作为一种有效且安全的生物敷料。
