Abstract:

BACKGROUND: There are various methods for the treatment and repair of deep second-degree burn wounds, which have diverse effects and have no uniform standards. Therefore, new technologies need to be developed.

OBJECTIVE: To observe the therapeutic effect of controlled debridement and traditional treatment on deep second-degree burn wounds.

METHODS: A total of 80 patients with deep second-degree burns from June 2015 to June 2018 were enrolled and divided into a positive control group and a controlled debridement group, with 40 patients in each group. The positive control group was coated with Bangerkang burn bacteriostatic cream, and the oil gauze was pressure-wrapped. The dressing was changed at 3, 6, 9, and 12 days after the injury. In the controlled debridement group, epidermal cell suspension was prepared according to the requirements of wound preparation and was sprayed onto the wound surface. The wound was then covered with Recell Kit self-contained protective film. The film was removed to keep the wound dry on the 3rd day after operation, and then the wound was observed at 6, 9, and 12 days after operation. The study protocol was approved by the Ethics Committee of the Xijing Hospital of the Air Force Military Medical University. All patients volunteered to participate in the study and sign an informed consent. Patient information was registered online and appropriate treatment was performed according to a random (software online) assignment.

RESULTS AND CONCLUSION: At 3, 6, 9, and 12 days after operation, the bacterial content, wound pain score, wound infection score and pro-inflammatory factor level in the controlled debridement group were significantly lower than those in the positive control group (P < 0.05). Moreover, there was no complication in both groups. These findings reveal that epidermal cell implantation combined with controlled debridement for deep second-degree burn wounds can achieve remarkable outcomes, which can significantly accelerate wound healing, reduce infection and alleviate the suffering of patients.
