Introduction

Chronic wounds are among the most difficult clinical conditions to treat. These wounds, resulting from various causes such as trauma, diabetes, and pressure ulcers, require long-term treatment and often significantly reduce patients’ quality of life. Traditional treatment methods may be ineffective in some cases. So, could high-intensity laser therapy (HILT) be a new hope for such wounds?

In this article, we will discuss the results of a randomized controlled study published in BMJ Open that examines the effects of high-intensity laser therapy (HILT) on chronic refractory wounds.

What Is High-Intensity Laser Therapy?

HILT, unlike traditional low-level laser therapies, has high power (above 500 mW) energy. This technology aims to accelerate wound healing by reaching deeper tissues, reducing inflammation, and promoting cellular regeneration.

In this study, energy was delivered to wounds using a laser with a wavelength of 1064 nm, and high amounts of multidirectional energy were transmitted to tissues in a short time. This characteristic is one of the key advantages that distinguishes HILT from other laser therapies.

Research Details

The research was conducted at a medical center in China between 2019-2020. Sixty patients were included in the study and divided into two groups:

Control Group: Only conventional wound care (debridement, saline irrigation, wound dressing).

Treatment Group: HILT was applied in addition to conventional wound care.

Both groups were treated for 3 weeks, and wound healing was measured using BWAT (Bates-Jensen Wound Assessment Tool) and PUSH (Pressure Ulcer Scale for Healing) scores.

What Do the Results Say?

The study results show that HILT is extremely effective in the treatment of chronic refractory wounds. In the treatment group:

  • A healing difference of -3.6 points was observed in BWAT scores.

  • A healing improvement of -5.3 points was achieved in PUSH scores.

These findings prove that HILT has significant advantages such as reducing wound size, increasing collagen production, and shortening wound healing time.

Advantages of HILT

1. Rapid Penetration and Effect: HILT’s high energy density reaches deeper tissues, initiating a rapid healing process.

2. Increasing Collagen Production: It accelerates wound healing by promoting collagen production in wound tissue.

3. Anti-Inflammatory Effect: By suppressing inflammation, it reduces symptoms such as pain and swelling.

The Future of HILT

The results of this study show that HILT is a promising method in the treatment of chronic wounds. However, more research is needed for different wound types (e.g., diabetic foot ulcers, pressure ulcers). Additionally, large-scale studies evaluating the long-term effects of HILT are also important.

Conclusion

High-intensity laser therapy offers significant advantages compared to traditional methods in the treatment of chronic refractory wounds. This innovative technology not only accelerates wound healing but also makes a positive contribution to the treatment process by improving patients’ quality of life.

In the future, more widespread use of HILT could be a revolutionary development for both patients and healthcare professionals. It is worth closely following this method that will revolutionize chronic wound treatment.
