Summary
Negative-pressure wound therapy (NPWT) and standard-of-care showed similar healing times for extremity burns. NPWT significantly reduced dressing changes, offering potential logistical benefits.
Area of Science:
- Burn treatment
- Wound healing
- Medical technology
Background:
- Negative-pressure wound therapy (NPWT) is a common treatment for complex wounds, including burns.
- This study evaluated NPWT's effectiveness in acute extremity burns compared to standard-of-care (SOC).
Purpose of the Study:
- To assess NPWT efficacy for acute upper and lower extremity burns.
- To compare NPWT outcomes against the established SOC at the institution.
Main Methods:
- Randomized controlled trial involving 65 patients with extremity burns (0.5%-10% TBSA).
- Patients were assigned to NPWT or SOC (polyhexanide gel, fatty gauze, cotton wool) until healing.
- Skin grafting patients received additional NPWT regardless of initial group allocation.
Main Results:
- No significant difference in healing time between NPWT and SOC groups (median 10 vs. 9 days, p=0.085).
- NPWT group had significantly fewer dressing changes (2.4 vs. 4.2, p<0.001).
- No differences observed in secondary surgical operations, pain, or functional outcomes.
Conclusions:
- NPWT and SOC demonstrate comparable wound healing times for extremity burns.
- NPWT offers a significant advantage by reducing the frequency of dressing changes.
- The study suggests NPWT may provide psychological and logistical benefits in burn management.
