Abstract:
We investigated the effects of microamperage electrical stimulation (MES) on the healing of skin incision in rabbits. Thirty male adult rabbits were randomly divided into sham-treated and experimental groups. Each group was divided into three subgroups, based on the duration of experiment (4, 7, and 15 days). A full-thickness incision was made on the skin of each rabbit. The experimental group received an MES of 200 microamperes current intensity for 2 h/day. Morphometrical and biomechanical evaluations were carried out. The mean number of fibroblasts at day 7 and the mean of tensile strength at day 15 were found to be significantly higher for the experimental group than for those in the sham-treated group (p < 0.01 and p < 0.05, respectively). Daily application of MES significantly accelerated the wound-healing process of full-thickness incision in the rabbits' skin.
Insights
Microamperage electrical stimulation (MES) significantly enhances skin incision healing in rabbits. This electrical therapy boosts fibroblast numbers and tensile strength, accelerating the natural wound repair process.
Area of Science:
- Regenerative Medicine
- Biomedical Engineering
- Dermatology
Background:
- Skin incision healing is crucial for patient recovery.
- Optimizing wound healing can reduce complications and improve outcomes.
- Current therapies have limitations in accelerating the healing process.
Purpose of the Study:
- To investigate the efficacy of microamperage electrical stimulation (MES) on skin incision healing.
- To evaluate the impact of MES on key healing indicators in a rabbit model.
Main Methods:
- Thirty adult male rabbits underwent full-thickness skin incisions.
- Animals were divided into experimental (MES) and sham-treated groups.
- MES (200 microamperes) was applied daily for 2 hours over 4, 7, and 15 days.
Main Results:
- The MES group showed a significantly higher mean fibroblast count at day 7 (p < 0.01).
- Tensile strength was significantly greater in the MES group at day 15 (p < 0.05).
- Daily MES application demonstrated a clear acceleration of wound healing.
Conclusions:
- Microamperage electrical stimulation is an effective therapeutic modality for accelerating skin incision healing.
- MES promotes key cellular and biomechanical aspects of wound repair.
- This study supports MES as a promising non-invasive method for enhancing dermal wound healing.
