How Does An Elbow Injection Or Aspiration Work?
Using image-guidance from fluoroscopy (X-rays that show motion inside your body in real-time) or CT scans, your doctor will place a long needle into the elbow joint and inject steroid medication to help reduce swelling and alleviate pain. To aspirate the elbow joint a needle is placed in the joint and fluid is aspirated and a sample is sent to the lab for analysis.
What Can I Expect Before, During, And After An Elbow Injection Or Aspiration?
A clinical staff member or technologist will bring you into the pre-procedure area and ask you to change into a gown. Your doctor will greet you, review the procedure, and answer any questions you may have. You will be brought into the procedure room, and you will be positioned on the procedure table.
The technologist will sterilize, and cover the area of your body where the needle will be inserted with a surgical drape. A local anesthetic is administered to numb the area where the needle will be placed. Once the area is numb, your doctor will advance the needle into your joint using image guidance. A small amount of x-ray dye can be injected to confirm needle placement. Once the needle is in the joint the medication can be injected or fluid can be aspirated. You might feel some discomfort as the medication is being administered. This should only last a short moment and will most likely dissipate as soon as the injection is complete. Once the medicine has been administered you may feel some tingling. You should tell your doctor if you feel any sharp pain.
The procedure takes approximately 30 minutes.
How Should I Prepare For An Elbow Injection Or Aspiration?
There are things you can do to make your experience more comfortable, and many of these will depend on your individual preferences. You might like to keep a list of questions or – as you’re doing now- educate yourself about the procedure.
Another important part of your preparation will be guided by your doctor:
- Your doctor may ask you to stop taking aspirin, non-steroidal anti-inflammatory drugs (NSAIDS), or blood thinners (such as Coumadin, Warfarin, Plavix, Fragmin) for a time before the procedure.
Some of your preparation will need to be timed to the procedure:
- The day before the procedure (or the Friday before, if you’re scheduled for a Monday procedure), a clinical staff member from the Interventional Radiology Department will call you. The clinical staff member will give you any additional instructions, and will ask if you have any questions.
- Take your medications as instructed
- When you arrive, make sure the clinical staff member and radiologist know about any allergies you may have, especially allergies to local anesthetics (such as lidocaine), general anesthetics, or x-ray dye (contrast media). If there’s any chance you might be pregnant, tell your radiologist.
What Should I Bring To My Elbow Injection Or Aspiration Appointment?
- Wear comfortable, loose-fitting clothes
- Wear comfortable shoes
- Avoid bringing jewelry or valuables
