ABSTRACT
Objective To study clinical application value of sacral and epidural block in treating lumbar intervertehral disc protrusion (LIDP), and explore technical operation methods, indications and con-traindications of sacral block. Methods Sacral block was adopted in 120 patients with LIDP(sacral group), they were injected triamcinolone acetonide 40 mg, vitamin B1 100 mg, vitamin B12 1 mg, 2% lidocaine 100 mg, added physiological saline 20-30 ml, twice a week, three times as a period. Compared therapy effect with epidural block (120 cases, epidural group). Results The achievement ratio of once puncture was 93.3% (112/120) in sacral group and 82.5% (99/120) in epidural group, P < 0.05. After treatment, the excellent and good rate of sacral group and epidural group were 85.0%(102/120) and 93.3%(112/120), there was not obvious difference, P>0.05, but the fair and bad rate were 15.0%(18/120) and 6.7%(8/120), there was ob-vious difference, P<0.05. Conclusions Sacral block and epidural block are effective methods to treat LIDP. They can relieve the stress at nerve root, especially sacral block, which has the advantages of easily operation, less pain, less side effect and safety.
