Contrast Therapy Promoting Skin Scald Repair

Area of Science:

• Biomedical Engineering
• Wound Healing Research
• Dermatology

Background:

• Contrast therapy (CT) involves alternating cooling and heating.
• Its efficacy in soft tissue injury recovery is under investigation.
• Skin scalds present a significant clinical challenge.

Purpose of the Study:

• To evaluate the effectiveness of CT in promoting skin scald repair.
• To compare CT with cold therapy (COT) and a control group.
• To investigate the underlying mechanisms of CT on burn healing.

Main Methods:

• A standardized rat scald burn model was utilized.
• Subjects were randomized into CT, COT, and model control (MC) groups.
• Assessed cutaneous blood perfusion, oxygen saturation, healing rates, cytokine levels, and histological changes.

Main Results:

• CT significantly reduced TNF-α and IL-6 levels by day 3.
• Enhanced localized blood perfusion and oxygen saturation were observed with CT.
• CT group showed increased epithelial thickness, reduced cell death (TUNEL-positive cells), less ulceration/edema, and faster wound healing rates.

Conclusions:

• CT improves local blood microcirculation and reduces inflammatory factors in scalded skin.
• CT accelerates wound healing in acute scald injuries.
• CT demonstrates potential as an effective therapeutic option for burn treatment.
