摘要

Background

Burn wounds are commonly encountered in clinical settings and the management aims at the prevention of mortality and morbidity due to disability. The platelet-rich plasma (PRP) is blood-derived biomaterial that is enriched with growth factors and cytokines that facilitate wound healing. The PRP has proven its efficacy in various other wounds, but its role in post-burn raw areas and graft take has not been validated. This proposed multicentre randomized controlled trial aims to evaluate the efficacy and safety of platelet-rich plasma as an adjunct therapy to split-thickness skin graft in burn patients with granulating raw wounds.

Method/design

This trial is an investigator-initiated, double-blind multicentre, randomized controlled parallel arm trial alongside trial cost-effectiveness analysis. Granulating deep second-degree and third-degree burns affecting 3–20% of total body surface area (TBSA) at 10–14th post-burn day will be included in the study. A total of 550 patients (275 in each group) will be randomized to receive either standard skin graft or allogenic PRP with skin graft treatment. The primary endpoint will be the mean percentage of graft-take on the 14th postoperative day. The result will be analyzed by two independent assessors who are blinded to the study. Secondary endpoints include (a) time taken for complete wound healing; (b) frequency of adverse events; (c) follow-up with scar index at 3 months, 6 months, and 1 year using the Patient and Observer Scar Assessment Scale (POSAS) score; (d) cost-effectiveness analysis of the intervention compared to the comparator; and (e) to estimate in a subset of participants the association between growth factor levels (PDGF BB and TGF ß-1) of activated PRP and clinical response.

Discussion

The proposed trial will be expected to verify the efficacy and safety of PRP for split-thickness skin graft (STSG) in deep second-degree or third-degree granulating wounds of burn patients based on the outcome of the study.
