Clinical Benefits of Laser Surgery
Laser surgery is recognized in human and veterinary medicine for its benefits to both patient and surgeon. 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.
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.
