Abstract:
BACKGROUND:In recent years, tissue engineering has made great progress, and skin tissue engineering is especialy noteworthy. Artificial dermis (PELNAC) is relatively used widely, but there is a lack of relevant reports on wound repair in children. OBJECTIVE:To investigate the clinical efficacy of Pelnac? METHODS:In a retrospective study, 22 patients with the wound of severe trauma were treated with Pelnac as skin graft dressings on treatment of the wounds of severe trauma in children. ? graft, negative-pressure wound therapy and split-thickness skin graft as experimental group (Pelnac? group), and another 19 patients treated with granulation formation dressing and split-thickness skin graft as control group. We colected data including the graft livability, the required re-operative times and the epithelization time after the skin graft. During the folow-up, the skin color and texture of survival skin, subcutaneous fulness, scar hyperplasia and the joint function were also evaluated. RESULTS AND CONCLUSION: In the Pelnac ? group, the graft livability was up to 90% within 10-14 days after grafting. The secondary split-thickness skin graft was required in two cases in the Pelnac? group and in eight cases in the control group. There was a significant difference in the graft livability (P < 0.05). The average epithelization time after the skin graft was (13.86±3.09) days in the Pelnac? group, which was significant shorter than the control group, (19.10±4.62) days, after the first time operation (P< 0.05). During the 10 months folow-up, the survival skin color and skin elasticity in the Pelnac? group was significantly better than that in the control group (P< 0.05). Better subcutaneous fulness and milder scar hyperplasy in the injured sites were obtained in the Pelnac? group compared with the control gorup. Five cases had certain joint function limitation in the Pelnac? group, compared to 10 cases in the control group, with a significant difference (P < 0.05). Artificial dermis Pelnac? has a stronger anti-infectious ability and higher graft livability. Pelnac? graft combined with negative-pressure wound therapy, granulation culture and split-thickness skin graft can shorten the epithelization time, improve wound healing and aleviate harm to the joint function after the skin graft.
