Lumbar Transforaminal Epidural
Steroid Injection
腰椎經椎間孔硬膜外類固醇注射
Overview(概述)
This outpatient procedure is an injection of a steroid-anesthetic medication. The medication can reduce swelling and inflammation of irritated spinal nerves. This procedure is performed to relieve pain in the lower back and pain that radiates from the back to the legs. The injection takes only a few minutes to complete.
本門診手術是注射類固醇-麻醉劑混合藥物。藥物可減輕受激惹的脊神經的腫脹和炎症。這個手術用於緩解腰痛及從腰到腿的放射痛。注射過程只需要幾分鐘時間。
Preparation(準備)
In preparation for the procedure, the patient lies face down. A cushion is placed under the abdomen, which causes the spine to bend in a way that opens the spaces on the sides of the spine. These spaces are called the foramina.
準備手術時,病人取俯臥位。肚子下墊軟墊,使脊柱彎腰,打開脊柱側方的開口,即椎間孔。
Anesthetic Injected(注射麻醉劑)
A local anesthetic is administered to numb the skin and the tissue that covers the spine.
用局部麻醉對脊柱表面的皮膚和組織進行麻醉。
Needle Inserted(穿刺)
When the area is numb, the physician carefully guides a needle into the foraminal space that surrounds the irritated nerve root.
當這個區域麻木後,術者小心地將針穿到受激惹神經根周圍的椎間孔區。
Contrast Solution Injected(注入對比造影劑)
A contrast solution is injected through the needle. The physician uses a fluoroscope (a type of x-ray device) to confirm that the tip of the needle is positioned correctly.
經皮穿刺針注入對比造影劑。術者用透視(一種X-線裝置)來確定針尖的位置正確。
Medication Injected(注入藥物)
After the needle's position has been confirmed, the physician injects a steroid-anesthetic medication. This medication bathes the irritated nerve roots. It will help alleviate the patient's pain.
當針的位置確認後,術者注入類固醇-麻醉劑混合藥物,浸潤受激惹的神經根。這將有助於緩解患者的疼痛。
End of Procedure(手術結束)
When the procedure is complete, the physician removes the needle and bandages the insertion site. The patient may feel significant relief after one injection. Some patients may need multiple injections before they feel the full benefit of the medication.
當手術結束後,術者將針拔出,注射部位包紮。一次注射後患者會感覺明顯緩解。有些病人需要進行多次注射才會感覺到藥物的好處。
