1.Patient Background

Species: Feline (American Shorthair)   Sex: Male   Age: 1 Year   Weight: 5kg

Chief Complaint:

Burns causing extensive and deep damage to the head and back, underwent large-area excision of damaged skin via plastic surgery, various circular and rectangular skin defects were repaired using techniques such as skin flap transposition and V-Y plasties.

Preoperative

Postoperative

2. Laser therapy treatment plan

Protocol Setup：Preset Protocol

Laser treatment frequency: once daily for 7 consecutive days, followed by once every 2 days, for a total of 9 treatments.

Given the large wound area of the affected cat, to prevent a sting sensation from excessive heat during initial irradiation, a preset protocol was used for the initial treatment. In subsequent treatments, the duration was increased by 25% based on the preset protocol. For postoperative wounds, a non-contact 25mm open probe was used for irradiation, moving at a speed of 3cm/second. The temperature of the beam could be felt by hand to avoid excessive heat.

3. Discussion

In this case, the wound area was large, making infection control and accelerated healing the key to treatment. Therefore, the laser therapy was successfully used to accelerate the wound healing process. Laser therapy utilizes specific wavelengths of light (red and near-infrared) to stimulate the organism's natural healing ability. The effects of laser energy include accelerated healing time, reduced pain, increased blood microcirculation, and reduced swelling [1, 2]. The four wavelength combinations of this therapy device are as follows: accelerating healing of surface tissues, inhibiting bacteria and promoting cell growth, accelerating ATP production to increase oxygen transport capacity, and improving blood microcirculation.
