Nerve blocks for the treatment of lumbar disc herniation have some positive effects, but the technique itself carries some risks. 1. Positive effect: The principle of nerve block treatment for lumbar disc herniation is similar to closure treatment, but it is more precise than closure treatment. Nerve block treatment is usually injected at the nerve root near the intervertebral foramen, and through the mixed effect of local anesthetic, nutritive nerve medicine or glucocorticoid and other drugs, it achieves the purpose of reducing the edema of the nerve root and long-lasting analgesia. 2. Therapeutic risk: most cases of nerve block treatment are blind puncture, so there is a risk of damage to subcutaneous nerves and blood vessels, usually recommended to have the conditions of the hospital can be in the CT-guided puncture treatment. The injection site is close to the subarachnoid space, so the drug may enter the subarachnoid space, causing a wider range of nerve block, affecting the normal nerve conduction; the patient may also experience anaphylaxis of the drug and have adverse reactions. The same disease, the patient’s physical condition is different, different stages of the disease, the treatment method is different, should be standardized treatment under the guidance of the doctor.
