The goal of this clinical trial is to comparison of physical microstructure-modified transparent silicone films and current conventional trauma dressings for second-degree burn wounds and post-skin graft wounds.The main question it aims to answer is :
The development of a new type of wound dressing is urgently needed because existing wound dressings cannot be transparent, easy to change, easy to store and inexpensive at the same time.
Participants will receive routine wound treatment, after which they will be covered with a clear silicone membrane with physical microstructure modification.
Researchers will compare vaseline gauze group and decellularised pigskin group o see if transparent silicone film with physical microstructure modifications promotes wound healing, reduces the number of dressing changes, reduces the damage to the wound and painful irritation to the patient during dressing changes, thus improving the quality of wound repair and saving medical costs.
