Defocused CO2 laser on equine skin
Defocused CO2 laser on equine skin
item no#BS-COL1
Summary
Reasons for performing study: No studies have been published on effects of treatment with a defocused beam carbon dioxide (CO2) laser on equine skin histology. A better understanding of this will help to define how lasers should be used, in order to reduce potential side effects.
Objective: To describe the acute effects of different doses of defocused CO2 laser, ranging from therapeutic to surgical levels, on equine skin.
Methods: Defocused CO2 laser was administered to the skin in the hamstrings (91 J/cm2), fetlock (137 J/cm2) and loin (450 J/cm2) areas of 13 Standardbred horses. The acute effects on skin histology were examined 90 min after the end of therapy.
Benefits of Veterinary Laser Surgery A Less Painful Alternative for Your Pet or Patient
Clinical Benefits
Veterinary laser surgery is recognized in human and veterinary medicine for the significant benefits it provides to both patients and surgeons. While several types of lasers are used for different applications, the primary device for soft tissue surgery in small and mixed animal practices is a carbon dioxide laser. The benefits of the carbon dioxide laser are many:
Reduced Pain – The CO2 laser beam seals nerve endings as it cuts through tissue. This reduces the amount of pain the patient feels during and after surgery.
Reduced Bleeding – The CO2 laser beam cauterizes and seals small blood vessels as it cuts. This laser energy achieves hemostasis and provides the surgeon with a bloodless surgical field in most procedures.
Reduced Swelling – There is no physical contact between the laser and the surgical region, eliminating the tearing and bruising of tissue associated with traditional surgical methods. Lymphatic vessels are also sealed.
Reduced Infection – Laser energy acts as an antibacterial agent by producing high temperatures, effectively eliminating microorganisms.
Quicker Recovery – As a result of all of the above, laser surgery provides the benefit your clients will appreciate the most: a quicker recovery for their pet.
What are the benefits of laser surgery for my pet?
There are three major advantages of laser surgery when compared to traditional stainless steel surgical scalpels, which are decreased pain, reduced bleeding and blood loss and reduced risk of infection.
Decreased Post-Operative Pain is accomplished when the laser seals the nerve endings as it cuts. This reduces pain impulses from the surgery site in the immediate post-operative period. Also, the decreased pain involved with laser surgery may allow the surgeon to remove small skin tumors using local anesthesia rather than having the pet undergo general anesthesia.
What surgeries can be performed with the laser?
Almost any soft-tissue surgery may be performed with the CO2 laser. Routine procedures such as ovariohysterectomy (spay) or castration (neutering) are commonly done with the laser. The CO2 laser is also used for skin tumor removal, eyelid surgery such as correction of entropion or ectropion, and some mouth and throat procedures. Your veterinarian will discuss whether CO2 laser is appropriate for use during your pet's surgery.
Results: Mild changes with focal spongiosis and subepidermal clefts were found after 91 J/cm2 irradiation and more severe changes with diffuse subepidermal clefts after the 137 J/cm2 dose. A homogeneous eosinophilic acellular zone of dermis and destruction of adnexal structures, and significant thinning of the epidermis was observed after the 450 J/cm2 dose.
Conclusions: The present study indicates acute dose-dependent changes in equine skin histology after laser treatment. Severe tissue damage was induced using a 450 J/cm2 dose.
Potential relevance: To reduce the potential side effects of defocused CO2 laser treatment, the laser parameters must be carefully evaluated. Caution should be taken if doses higher than 91 J/cm2 (16 W, 4 min, and 42 cm2) are used in irradiation of equine skin.
Benefits of CO2 Surgical Laser
Laser surgery has a number of advantages over traditional cutting and cauterizing surgical techniques in that there is few or no bleeding, virtually no swelling, minimal pain for patients post-surgically, and such precision that only diseased tissue is removed.
