A comparison of efficacy of autologous platelet-rich plasma and conventional sutures in anchoring split skin graft on wounds

Abstract

Context: Split thickness skin grafting (STSG) restores cutaneous cover over wounds thus protecting the underlying surface from contamination, fluid loss and stimulates healing. Autologous platelet rich plasma (PRP) provides a large number of platelets and high concentration of growth factors which promote overall uptake of STSG. Aims: The aim of this study was to assess the immediate, subsequent adhesion and final take of STSG with application of PRP over recipient site. Methods and Material: 1 year Randomised Control Trial where 80 wounds of various aetiologies were randomised into intervention group (n=40) which received PRP before placing STSG on recipient site and control group (n=40) in which the graft was fixed in place with sutures alone. Immediate graft adhesion and subsequent graft uptake were compared between the two groups and statistical analysis was done with: SPSS Version 20. Results: Irrespective of aetiology, and size, among a total of 80 wounds 87.5% grafts had adhered by 1st minute of application in the intervention group compared to nil in control group (p0.05) Conclusions: Application of topical PRP facilitates STSG uptake. It decreases operative time by decreasing mobility of graft over the wound bed. Thus, use of PRP improves outcome of split thickness skin graft in wounds of various aetiologies and we recommend use of the same at recipient site of STSG. CTRI/2021/06/034401
