BACKGROUND: Stellate ganglion block (SGB) is known to increase blood flow to the innervations area of the stellate ganglion. Near infrared spectroscopy reflects an increased blood volume and allows continuous, non-invasive, and bedside monitoring of regional cerebral oxygen saturation (rSO2). We investigated the influence of SGB on bilateral cerebral oxygenation using a near infrared spectroscopy. METHODS: SGB was performed on 30 patients with 1% lidocaine 10 ml using a paratracheal technique at the C6 level and confirmed by the presence of Horner's syndrome. The blood pressure (BP), heart rate (HR) and rSO2 were measured before SGB and 5, 10, 15 and 20 minutes after SGB. Tympanic temperature of each ear was measured prior to SGB and 20 minutes after SGB. RESULTS: The increments of the rSO2 on the block side from the baseline were statistically significant at 5, 10, 15 and 20 minutes. The rSO2 on the non-block side compared with the baseline, however, decreased at 15 and 20 minutes. The difference between the block and the non-block sides was significant at 15 and 20 minutes. The BP at 10, 15 and 20 minutes was increased and the HR was increased at 10 and 15 minutes. CONCLUSIONS: We observed an increment of the rSO2 on the block side from the baseline; however, the rSO2 on the non-block side decreased
