| Objective：The aim of the present study was to compare the efficacyof Pelnac covered by split-thickness skin graft with own granulationformation dressing split-thickness skin graft for treatment of the wounds ofsevere trauma in children in a retrospective study.Methods：In a retrospective study,22patients with the wound ofsevere trauma were treated with Pelnac graft and split-thickness skin graftand19patients with own granulation formation dressing split-thickness skingraft as the control group. We collected data including the graft livability, therequired re-operative times and the epithelization time after the skin graft.Follow-up in ten months, the skin’s color and texture of survival skin,subcutaneous fullness, scar hyperplasy and the joint function limited extentof were evaluated.Results： Patients in the Pelnac group, grafts livability was up to90%in the10-14days. A second time for split-thickness skin graft wererequired in two cases at the Pelnac group and in eight cases at the controlgroup and showed statistical significant differences （X2=4.42υ=1×1 p<0.05). the average epithelization time after the skin graft (13.86±3.09days)significant shortened compared with the control group (19.10±4.62days)after the first time operation（t=-4.32，υ=39p<0.05). Follow-up in tenmonths, the survival skin’s color （Rn实=0.080±1.06）and texture in thetreatment group （Rn实=0.081±0.11）was significantly better than controlgroup (P<0.05),good subcutaneous fullness and scar hyperplasy in theinjured sites were obtained. Five cases had certain joint function limitation,compared to tent cases in the control group, statistical significant differenceswere examined, as well （X2=3.93υ=1×1p<0.05).Conclusion：Artificial dermis Pelnac dressing split-thickness skingraft has higher graft livability and shorter epithelization time after the skingraft. In the treatment of the wound of severe trauma, it improves the qualityof the wound alleviates joint function, as well. |
