Clinical evaluation of image-guided nerve block in pain therapy. - clinical evaluation of nerve block

Evation in temperature: by over 1 (sympathetic block, n = 62) and by less than 1 (non-sympathetic block, n = 27). Finger blood flow decreased significantly just after a change in posture after SGB in both groups. In the sympathetic block group, the ratio of finger blood flow in the long sitting position / supine position with a change in posture significantly increased after SGB compared with before SGB (before SGB: range 0.09-0.94, median 0.53, after SGB: range 0.33-1.2, median 0.89, p < 0.0001).
