Suitability of Permanent Probe Implants For the Measurement of Intramedullary Perfusion and Temperature Near the Bone Cortex: A Pilot Study Using a Rabbit Model
This study was conducted to test the suitability of permanent probe implants for the measurement of intramedullary perfusion by laser Doppler flowmetry and for the measurement of temperature near the bone cortex. Measurements were carried out on the conscious animal in order to rule out the influence of anaesthesia on intramedullary perfusion and temperature. During the first experimental animal trials, some of the probes made of polysulphon broke and/or gave false temperature measurements, so the original probe design was modified. The probes were reinforced with metal, and the temperature sensors were made less permeable to moisture. These modified probes were found to be suitable for permanent measurement of intramedullary perfusion and of temperature near the cortex in the conscious rabbit.
