An Outcome Analysis of Fibrin Sealant versus Staples for Fixation of Split-Thickness Skin Grafts

Background  Skin grafting plays a vital role in post-burn and post-traumatic wound management. Split-thickness skin grafts (STSG) are traditionally fixed using staples or sutures, which have tedious application and their removal necessitates painkillers, medical equipment, and human intervention. As an alternative, fibrin sealant is a biological tissue adhesive, composed of thrombin, calcium, and fibrinogen. Fibrin sealant promotes hemostasis and acts as a biological adherent. Objective  The aim of this study was to evaluate the outcomes (graft take, wound healing and complications) of fibrin sealant and staples for STSG fixation. Methods  It is a randomized controlled trial on 40 patients with wounds of minimum 400 cm ² . Wound area was divided into equal halves and randomly allocated to the study group or control group. In the study group, 4 mL per 200 cm ² of fibrin sealant was sprayed followed by STSG application. In the control group, STSG was fixed with only skin staples. Evaluation was done on postoperative days 3, 5, 15, and 30 for graft take, hematoma/seroma, infection, and complete wound healing. Results  The mean graft take was significantly higher ( p -value < 0.05) in the study group than in the control group (91 vs. 89%). No seroma or hematoma formation was seen in either group. Complete wound healing was seen in more patients in the study group, but the difference was statistically insignificant. Conclusion  Fibrin sealant is an excellent alternative to staples for skin grafting, with the advantage of better graft take and being free of pain that is incurred during staple removal.
