Abstract

To measure regional saturation of oxygen ( rSO 2 ) of hemoglobin and total hemoglobin index (HbI) in the brain (through the molera of the head) and skeletal muscle (musculus gracilis) of conscious Chihuahua dogs using an examiner’s finger-mounted near-infrared spectroscopy (NIRS) device, Toccare, we investigated brain and skeletal muscle NIRS in 48 Chihuahuas without severe disease. To measure rSO 2 and total HbI, a Toccare probe was placed on the molera of the head and musculus gracilis of each dog for real-time recording. Stable NIRS values were obtained within 10 s. We also examined the effect of anesthesia on rSO 2 and total HbI of a Chihuahua. Cerebral rSO 2 values ( 59 % ± 7 % ) were significantly lower than those obtained at femoral regions ( 67 % ± 6 % ), whereas total HbI values in the brain ( 0.38 ± 0.09 ) were significantly higher than those of the musculus gracilis ( 0.20 ± 0.05 ). Sedation with a combination of medetomidine and ketamine decreased cerebral rSO 2 along with a corresponding reduction in heart rate. Sevoflurane anesthesia with 100% O 2 maintained rSO 2 in the brain with a.
