The application of BC dressing and VG dressing in second-degree burn wounds. Bacterial cellulose (BC) dressing and Vaseline gauze (VG) dressing were used in second-degree burn wounds in the two-center randomized controlled clinical study. Their treatment efficacies were compared as well. (a) Deep second-degree burn wound on left forearm. (b) BC dressing was applied. BC dressing was translucent, which allowed the wound to be checked easily. (c) Without changing BC dressing, wound healed on day 12; BC dressing dried up and fell off. (d) Deep second-degree burn wound on right forearm. (e) VG dressing was less translucent than BC dressing, making checking less convenient. 12 days later, VG was stuck to the wound bed and was not able to be changed. Hemorrhage was observed when changing outer cover of VG. (f) Wound healed on day 21, but there were difficulties when removing VG.
