Burn Injuries

3.1K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Summary

Wireless Microcurrent Stimulation (WMCS) significantly improved blood flow and oxygen levels in burn wounds. This non-contact therapy enhances perfusion, potentially accelerating healing in partial thickness burns.

Area of Science:

  • Biomedical Engineering
  • Dermatology
  • Wound Healing Research

Background:

  • Skin breakdown, such as wounds, generates an electric potential known as the current of injury, crucial for wound closure.
  • Burn wounds exhibit varying perfusion zones that dictate treatment strategies, including conservative management or skin grafting.
  • Understanding the immediate effects of electrical stimulation on burn wound perfusion is vital for optimizing therapeutic outcomes.

Purpose of the Study:

  • To investigate the immediate, quantifiable effects of electrical stimulation on skin perfusion in burn wounds.
  • To assess the efficacy of Wireless Microcurrent Stimulation (WMCS) as an adjunct therapy for partial thickness burn wounds.
  • To compare the impact of WMCS on microcirculation in burn wounds versus healthy skin.

Main Methods:

  • Wireless Microcurrent Stimulation (WMCS) was applied as an adjunct therapy to 10 patients with partial thickness burn wounds.
  • Laser Doppler (LDI) was used to quantify microcirculation in the skin before and after WMCS treatment.
  • A control group of 10 healthy individuals was included for comparative analysis.

Main Results:

  • A single WMCS application significantly increased mean flow, velocity, hemoglobin, and oxygen saturation in partial thickness burn wounds.
  • While healthy skin also showed increased parameters post-WMCS, the effect was considerably less pronounced than in thermally injured skin.
  • WMCS demonstrated a significant enhancement of microcirculatory parameters specifically within the burn wounds.

Conclusions:

  • Non-contact WMCS non-invasively improves blood flow in critically perfused partial thickness burn wounds.
  • WMCS shows potential as a promising adjunct tool in burn treatment by enhancing perfusion and reducing the zone of stasis.
  • This therapy may lead to faster healing of burn wounds without systemic effects or disturbance to the wound site.
