Suprascapular Nerve Block
WHAT IS A SUPRASCAPULAR NERVE BLOCK?
The suprascapular nerve, situated at the back of the shoulder blade (scapula), supplies the shoulder joint and two of the rotator cuff muscles. A suprascapular nerve block is a diagnostic procedure to identify the source of shoulder pain, involving the injection of local anaesthetic and/or steroid onto the nerve to reduce inflammation and swelling. Compressions of the suprascapular nerve can occur due to various reasons, including direct shoulder injury or wear and tear over time. If pain relief is achieved from the block, the next stage of treatment, such as radiofrequency ablation (RFA), may be discussed during your follow-up appointment with your doctor.
HOW IS THE PROCEDURE PERFORMED?
During your procedure, an anaesthetist will administer intravenous sedation to help you relax. This minimally invasive process takes place in a hospital theatre or day procedure centre, with specialised imaging guidance. Your doctor will use this imaging to accurately place a needle near the nerves supplying the suprascapular nerve in the shoulder. Then, they will administer local anaesthetic and/or steroids to numb the nerve for effective pain relief.
HOW LONG DOES THE EFFECT LAST?
This relief is only intended to last approximately 4 to 12 hours. This is meant to determine and confirm if these nerves are responsible for the pain.
WHAT SHOULD BE DONE BEFORE THE PROCEDURE?
Prior to the procedure, you may need to stop blood thinning products as directed by your doctor. Other regular medications can be taken with a sip of water on the morning of the procedure. Insulin-dependent diabetics will likely be prioritised on the list and should bring their insulin for potential administration after the procedure. Hospital staff will call you the day before the procedure to provide fasting and admission times. DO NOT eat, drink, smoke, or chew gum before the procedure. Arrange for someone to drive you home afterward, as you won’t be able to drive for 24 hours due to the received anaesthesia.
WHAT IS THE NEXT STEP AFTER THE PROCEDURE?
After a short time in the recovery ward, you will be discharged home. It is important that you perform your daily activities as normal to test the effectiveness of the procedure. You will be given a pain diary by staff to complete following your procedure for the first 48 hours to score your pain. Please bring this with you to your follow up appointment. You can remove the dressing after 24 hours.
WHAT ARE THE RISKS AND SIDE EFFECTS?
Serious side effects and complications are rare. The most common problem after the procedure is having pain in the area of the procedure for 1 to 3 weeks. Please contact your local GP or the rooms if you have any allergic reaction to the medication administered in hospital, signs of infection at your procedure site.
