You may know that we use ultrasound to take images of the soft tissues in your body But ultrasound can also be used to guide treatments such as: taking a sample of the fluid from a joint or from a fluid collection, injecting local anaesthetic and steroid into soft tissue or a joint to provide pain relief and reduce swelling. Ultrasound uses high frequency sound waves to obtain pictures of the inside of your body which help us to carry out these procedures more precisely and effectively. It’s popular because it doesn't expose you to any radiation, is quick and non-invasive. It has been used without any side effects for over thirty years. There are some important things you need to address before you come for your treatment Ultrasound scans are performed in the radiology department and it’s best to arrive in plenty of time. We recommend that you bring a partner, friend or relative with you who can drive you home. However, they will not be allowed inside the examination room, but can be there to keep you company. Also, please don't bring young children as there are no facilities available to look after them. There are some instances when it is not safe for us to carry out your procedure. Please phone us in advance if you are on Zyban (anti smoking medication), any anticoagulant besides aspirin, or have any allergies. Our radiologist and sonographer will talk to you about these and agree on the best course of action. Please also let us know before you come if you have any mobility problems for which you may require assistance. When preparing for your visit, we recommend that you wear loose fitting clothes so that it is easier to expose and scan the area of your body that is being investigated. When you are called into the examination room you will be met by a radiologist or sonographer and an assistant. The room is quite dark so that it is easier to see the images of your body on the screen. You will be asked to sit down or lie flat on a couch. The radiologist or sonographer will put a small amount of gel on the area to be scanned. They will then use a probe to take images. The probe will be moved over your skin and images will appear on a screen. You may experience some pushing as the probe is positioned so that the area being investigated can be seen more clearly. This should not be painful, but may be a little uncomfortable. You may be asked to change position to help us get the images we need. Once the area of concern has been imaged with the ultrasound probe, the radiologist or sonographer will talk you through the procedure. They will ask if you are happy for them to proceed. Please feel free to ask any questions that you may have. The area will be thoroughly cleaned. If you are having a sample of fluid taken from your joint or from a fluid collection, the radiologist will hold the ultrasound probe against your skin with their other hand, they will insert a small needle into your joint or into the fluid collection and withdraw some fluid into a syringe. This can be uncomfortable, but will not last for very long. The fluid can help your doctor diagnose and manage the problem If you are having a local anaesthetic with steroid injected into your joint or into a soft tissue area, the radiologist and sonographer will follow a very similar procedure, but instead of withdrawing fluid, they will inject the medication into the correct area with a needle. Afterwards they will apply a small plaster over the injection site and you will be able to get dressed and go home. The procedure will take about 5 minutes. Many patients will gain a lot of relief from having these treatments, although there is always the risk of side effects with any procedure. These include infection, worsening symptoms, an allergic reaction, tendon damage and skin changes. If you feel unwell after your procedure, or develop new redness or swelling around the site of injection, please see your GP during working hours or attend A&E out of hours. You will need a follow up appointment with the doctor who requested the treatment. Depending on your referring clinician, details will be sent to you or you may need to arrange one.
