Abstract

Digital nerve samples obtained from horses using a CO₂ laser for surgical excision at various power densities in both continuous wave (CW) and superpulse (SP) modes were examined histologically and using a scanning electron microscope. Preliminary data suggest that the lowest power density examined (637 W/cm²) in CW mode provided a wide zone of thermal change and the best tissue coagulation. Power densities of 15,924 and 31,847 W/cm² SP mode showed a narrower zone of thermal change, and a coagulated but much more disrupted excisional surface than that which was observed at lower power densities, or at the same power densities where CW mode was used. Clinical trials where equine palmer digital neurectomies have been done at 637 W/cm² (5 W, 1.0 mm spot size) CW and at 47,771 W/cm² (15 W, 0.2 mm spot size) SP have not been completed at this time. It has been observed that attempting the surgical procedure at 127,388 W/cm² (40 W, 0.2 mm spot size) CW was difficult for the surgeon to control and resulted in marked post surgical discomfort of the patient. For these reasons we eliminated power densities above 63,694 (20 W, 0.2 mm spot size) from our neurectomy studies.
