Abstract
Objective: To determine the impact on skin perfusion of ice pack application on healthy skin.
Methods: A region of skin on the ventral midline was clipped from 10 healthy dogs. Skin perfusion was assessed with laser speckle contrast imaging at baseline, immediately after 15 minutes of icing, and 15 minutes after removal of the ice pack. Mean speckle contrast was calculated from the laser speckle contrast imaging images at all time points. Mean speckle contrast is a unitless measurement that is inversely proportional to skin perfusion. Local skin temperature was also assessed.
Results: Skin temperature decreased from 92.2 ± 0.6 °F at baseline to 69.1 ± 1.1 °F immediately after icing and had increased to 87.5 ± 0.5 °F at 15 minutes after icing. Skin perfusion decreased (mean speckle contrast increased) by a mean of 10.0 ± 5.7% from baseline to immediately after icing and by a mean of 14.8 ± 7.5% from baseline to 15 minutes after icing.
Conclusions: Application of ice to the skin for 15 minutes decreases skin perfusion for at least 15 minutes after ice pack removal.
Clinical relevance: Veterinarians should consider that a decrease in skin perfusion is associated with the application of an ice pack when deciding whether to implement this therapy; however, additional research is warranted to determine whether there is an impact on healing.
期刊介绍:
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
