To assess the efficacy of cultured epidermal autografts (CEA) for closure of burn wounds in pediatric burn patients with full-thickness burns of more than 90% total body surface area.
Paucity of donor sites in massive burns makes the use of expanded skin of paramount importance. CEA techniques have been used in burned patients with differing and controversial results. The true impact and the efficacy of such techniques in massive burns remain uncertain.
Patients with full-thickness burns of more than 90% body surface area treated between May 1988 and May 1998 were studied. Patients grafted with CEA were compared with patients grafted with conventional meshed autografts. Rates of death and complications, length of hospital stay (LOS), hospital cost, acute readmissions for reconstruction, and quality of scars were studied as outcome measures.
Patients treated with CEA had a better quality of burn scars but incurred a longer LOS and higher hospital costs. Both groups had comparable readmissions for open wounds, but patients treated with CEA required more reconstructive procedures during the first 2 years after the injury. The incidence of sepsis and pneumonia in both groups was comparable.
Conventional meshed autografts are superior to CEA for containing hospital cost, diminishing LOS, and decreasing the number of readmissions for reconstruction of contractures. However, the use of CEA provides better scar quality such that perhaps future research should focus on bioengineered dermal templates to promote take and diminish long-term fragility.
评估培养的自体表皮移植片(CEA)对烧伤总面积超过90%的小儿深度烧伤患者烧伤创面闭合的疗效。
大面积烧伤时供皮区不足使得使用扩张皮肤至关重要。CEA技术已用于烧伤患者,但其结果各异且存在争议。此类技术在大面积烧伤中的真正影响和疗效仍不确定。
研究1988年5月至1998年5月间治疗的烧伤总面积超过90%的深度烧伤患者。将接受CEA移植的患者与接受传统网状自体皮移植的患者进行比较。将死亡率、并发症发生率、住院时间(LOS)、住院费用、重建的急性再入院率和瘢痕质量作为观察指标进行研究。
接受CEA治疗的患者烧伤瘢痕质量较好,但住院时间较长且住院费用较高。两组开放性伤口的再入院率相当,但接受CEA治疗的患者在受伤后的头2年内需要更多的重建手术。两组的败血症和肺炎发生率相当。
对于控制住院费用、缩短住院时间和减少挛缩重建的再入院次数,传统网状自体皮优于CEA。然而,CEA的使用可提供更好的瘢痕质量,因此未来的研究或许应聚焦于生物工程真皮模板,以促进移植成活并减少长期脆弱性。
