Granulation-embedded autologous skin grafting improves healing chronic wounds at high altitudes: a pilot study
1Senior Department of Burns and Plastic Surgery, Fourth Medical Center of PLA General Hospital, Beijing, China.
Background:
The management of chronic wounds presents a challenge for surgeons. In this pilot study, the authors established a novel auto-grafting approach for chronic wounds and evaluated its efficacy.
Purpose:
The objective of this pilot study was to observe the clinical efficacy of granulation-embedded skin grafting for the treatment of chronic wounds at high altitudes.
Methods:
The data of 45 patients with chronic wounds were obtained from the medical records of the Yushu People's Hospital. Patients were divided into stamp skin-grafting and granulation-embedded skin-grafting groups. Skin graft survival rate, wound coverage rate, and wound-healing time were observed and recorded. The length of hospital stay and 1% total body surface area (TBSA) treatment cost were compared.
Results:
Significant differences were noted in skin graft survival rate (94% ± 3% vs 86% ± 3%, P < .01), wound coverage rate on postoperative day 7 (61% ± 16% vs 54% ± 18%, P < .01), and wound-healing times (23 ± 2.52 days vs 31 ± 3.61 days, P < .05). The length of hospital stay and 1% TBSA treatment cost were significantly reduced in the granulation-embedded skin grafting group (P < .05).
Conclusions:
Granulation-embedded skin grafting can improve the healing of chronic wounds at high altitudes. These findings provide a new approach to the clinical treatment of chronic wounds.
