Usefulness of lyophilized pig skin dressings in wound healing as treatment for diabetic foot ulcer

Abstract

Aim: To demonstrate the usefulness of lyophilized pig skin dressings versus usual management with silver sulfadiazine in wound healing treatment for diabetic foot ulcers. Materials and Method: In this quasi-experimental study, we included patients diagnosed with diabetic foot. We established two groups with a distribution (2:1), the exposure group treated with lyophilized pig skin dressings (10 patients) and the control group (5 patients), the standard of care with silver sulfadiazine. Usefulness was measured with wound healing in treatment weeks. Statistical analysis included t-test, z-test, simple logistic regression, and calculation of probability of an event. Results: Wound healing time was shorter in the group treated with lyophilized pig skin dressing (10.20 weeks) than in the group treated with silver sulfadiazine (13.8 weeks). At 9 weeks after treatment started, 50% of patients treated with lyophilized pig skin dressings had complete wound healing compared with the patients in the group managed with silver sulfadiazine. (20%). The probability of wound healing been completed at 11 weeks in a patient managed with silver sulfadiazine is 20%, compared to lyophilized pig skin dressings is 80%. Conclusion: Lyophilized pig skin dressings had better outcomes than silver sulfadiazine in wound healing treatment for diabetic foot ulcers inside the study. Is mandatory develop another study with a randomized design to determinate the effectiveness as a therapeutic alternative.
