Abstract：
Hypertrophic scarring is a significant complication post burn injury, especially for delayed healing after 3 weeks. Burn injuries healing prior to 3 weeks also have the potential to develop hypertrophic scarring, even when prescribed prophylactic conservative scar interventions. A retrospective chart audit reviewed 326 burn patients treated at a paediatric tertiary hospital from 2014 to 2019 who sustained a partial thickness burn, healed >14 days and did not receive skin grafting. A scar was deemed hypertrophic if >1 mm in height. Early hypertrophic scar prevalence was defined as 3-6 months post burn, while persistent hypertrophic scarring was defined as 12-18 months post burn. Median days to wound closure was 18. The prevalence of early and persistent hypertrophic scarring was 56.1% and 16.3%, respectively. Seventeen (5.2%) children underwent medical interventions for scar modulation. Early signs of hypertrophic scarring were seen in just over half the patients presenting to burn therapy and despite scar intervention, persistent hypertrophic scarring was seen in 16.3%. At both time points, just over half of the children presenting healed between 14 and 21 days. Therefore, children healing prior to 21 days have potential to develop hypertrophic scarring.
摘要：
增生性瘢痕是烧伤后的重要并发症，特别是3周后延迟愈合。烧伤前3周愈合也有可能形成肥厚性瘢痕，即使规定了预防性保守性瘢痕干预措施。回顾性图表审核回顾了2014年至2019年在儿科三级医院接受治疗的326例烧伤患者，这些患者持续了部分厚度烧伤，愈合>14天，没有接受植皮。如果高度>1mm,则认为疤痕是肥厚的。早期增生性瘢痕患病率定义为烧伤后3-6个月，而持续性肥厚性瘢痕形成定义为烧伤后12-18个月。伤口闭合的中位天数为18天。早期和持续性增生性瘢痕的患病率分别为56.1%和16.3%,分别。17名（5.2％）儿童接受了疤痕调制的医疗干预。尽管有疤痕干预，但在接受烧伤治疗的患者中，仅有一半以上的患者出现了肥厚性瘢痕形成的早期迹象。持续性肥厚性瘢痕的发生率为16.3%。在这两个时间点上,超过一半的儿童在14到21天之间痊愈。因此,21天之前愈合的儿童有可能形成肥厚性瘢痕。
