Effect of precise partial scab removal on the repair of deep partial-thickness burn wounds in children: a retrospective study.

Abstract

BackgroundThe choice of treatment methods for children with deep partial-thickness burn wounds (DPBWs) is an issue that requires careful consideration from surgeons. The purpose of this study was to evaluate the efficacy of precise partial scab removal (PPSR) in the treatment of DPBWs in children.MethodsWe retrospectively analyzed the clinical data of 78 children with DPBWs. The children were divided into a PPSR group (n=37) and a routine dressing change (RDC) group (n=41). In the PPSR group, an electric dermatome was used to cut the scab in the early post-injury period. The thickness scale of the electric dermatome was set to 0.1 mm. The scab was removed to the base with scattered bleeding points. There was still a small amount of necrotic tissue in the base of the wound. For the acellular dermal matrix, the first dressing change was about 1 week after surgery. The RDC group was given conventional wound-dressing treatment. The wound dressing was changed with epidermal growth factor, silver-zinc antibacterial cream, and dressing change. The frequency of dressing change was adjusted once a day or once every other day depending on the condition of wound secretions. The hospitalization time, wound-healing time, fever duration, antibiotic use time, number of subsequent operations, and overall hospitalization expenses were compared between the two groups.ResultsThe wound-healing time of the PPSR group was 19.86±6.4 days, and the wound-healing time of the RDC group was 24.15±7.12 days (P=0.0068). The duration of fever in the PPSR group and RDC group was 2.62±1.99 and 4.44±3.10 days, respectively (P=0.0032). The antibiotic use time in the PPSR group and RDC group was 4.0±1.33 and 4.83±1.88 days, respectively (P=0.0292). The overall hospitalization cost of the PPSR group and RDC group was yuan renminbi ¥37,852.84±10,894.64 and ¥38,047.46±19,450.37, respectively (P=0.9573).ConclusionsPPSR can shorten wound-healing time, reduce the frequency of dressing changes, shorten the time of fever in children, lower the frequency of antibiotic use, and decrease number of dressing changes on the wound.
