选择性颈椎神经根阻滞（Selective Nerve Root Block,SNRB) 是用于确定颈部神经痛来源的一种注射技术，有时也可以长时间缓解疼痛。

警告：请在有WIFI的场所观看视频，土豪请随意。

Cervical selective nerve root block, or SNRB, is an injection used to identify the source of nerve pain in the neck and sometimes to also provide longer-term pain relief.

颈椎选择性神经根阻滞（Cervical selective nerve root block,SNRB)是用于确定颈部神经痛来源的一种注射技术，有时也可以长时间缓解疼痛。

Nerve pain in the neck that radiates down into the shoulders, arms, and hands can develop when a cervical nerve root is compressed or inflamed due to a degenerated or herniated disc, spinal stenosis, or other degenerative spinal changes.

颈部神经痛向下放射到肩部、胳膊和手，可因退变或疝出的椎间盘、椎管狭窄或其它退变性脊柱改变引起颈椎神经根受压或炎症导致。

As the procedure begins, the patient lies face-down and may receive a sedative.

手术开始，患者取俯卧体位，并予镇静剂。

The doctor injects a local anesthetic into the skin over the area that is suspected of being the source of nerve pain.

医生在预先设想神经痛起源部位表面的皮肤上注射局麻药。

Under X-ray guidance, the doctor injects a contrast dye to aid in correct placement of the needle at or near the suspected compressed or irritated nerves.

在X线引导下，医生注射显影剂以指导穿刺针正确插到预想神经受压或刺激部位或其周围。

Once the needle is safely positioned, there is a second injection into the nerve root where it exits the foramen, a side opening where two vertebrae meet.

当穿刺针安全插到位后，在神经根离开椎间孔的部位，即两个椎体相连接处侧面的开口处进行二次注射。

This injection contains both lidocaine, a type of anesthetic, and a steroid, such as cortisone.

这次注射的药物包括利多卡因（一种麻醉剂）和激素（比如考的松)。

If the patient's nerve pain disappears when the anesthetic is injected, then the correct nerve root has been identified.

当麻醉剂注射后，如果病人神经痛症状消失，那么就可判定这是目标神经根。

The steroid injection often works for a longer period of time than the anesthetic, helping to reduce inflammation and promote healing of irritated nerve roots.

激素注射后起效时间比麻醉剂长，有助于减轻炎症，促进受刺激神经根的愈合。

The injection site is bandaged. Patients can usually leave the hospital the same day.

注射部位贴创可贴。通常患者在当天可以离院。
