Introduction. Autologous skin transplantation is a common treatment for patients with full-thickness burns. Postoperative wound care is essential for skin graft donor and recipient sites, but traditional wound dressings such as cotton and gauze do not form an effective barrier to bacteria, and patients can feel uncomfortable when replacing dressings. Materials and Methods. The goal of this study was to evaluate the use of an antimicrobial spray dressing (JUC Spray Dressing, NMS Technologies Co Ltd, Nanjing, China), with respect to its antimicrobial efficiency and the degree of pain experienced by patients. Results. The authors found the antimicrobial spray can reduce pain during the recovery period, while providing equivalent antibacterial protection to the control treatment (AQUACEL Hydrofiber Wound Dressing, ConvaTec, Bridgewater, NJ) based on skin culture tests. The spray did not adversely affect the wound site recovery. No significant side effects were present during the treatment period. Conclusion. This antimicrobial spray could potentially be used in wound dressing applications.
