Both of these papers, one from England and one from the United States, evaluated a continuous glucose monitoring system (CGMS-Medtronic MiniMed, Northridge, CA) that has been approved by the Food and Drug Administration for use in human diabetic patients. The system includes a flexible electrode sensor that measures glucose concentrations in the interstitial fluid. The sensor is inserted into the subcutaneous tissue and attached by a cord to a recording device. The recording device is secured to the animal either by taping to a harness or halter or holding in place with a bandage. The group in the Untied States also used cyanoacrylate adhesive to secure the sensor and the cord in place. However, the group in England had an anecdotal report that glue interfered with the sensor, so they used an adhesive pad with extra tape to keep the sensor secure. The CGMS was well tolerated by the animals. Interstitial fluid glucose levels were measured and compared with the whole blood glucose concentrations, and there was a positive correlation between the samples.
