Continuous Glucose Monitoring for Diabetic Cats

Wiedmeyer, C. E. and A. E. Declue (2008). “Continuous glucose monitoring in dogs and cats.” J Vet Intern Med 22(1): 2-8.

Continuous glucose monitoring systems originally designed for human diabetic patients have been adapted for use in dogs and cats. Sensors continually measure glucose in subcutaneous interstitial fluid (ISF), rather than in blood. A small, flexible sensor is inserted through the skin into the subcutaneous space, secured to the skin, and attached to a recording device. The ISF glucose is recorded and stored every 5 minutes (288 readings per 24 hours). After the device is removed, the data are downloaded to a computer for analysis. The instrument can remain in place for several days, hospitalization of the patient is not necessary, and the normal daily routine of the animal can be maintained. This review from the University of Missouri-Columbia is designed to describe the technology behind the continuous glucose monitoring system, describe the clinical use of the instrument, provide clinical examples in which it may be useful, and discuss future directions for continuous glucose monitoring in dogs and cats.
