Intended Benefits

A peripheral nerve block involves placing an injection near to one of the larger nerves in the body. The injection is not near the spine, hence its label “peripheral” The aim is to reduce pain that is thought to arise from some form of irritation of the nerve.

Risks of this treatment

There is a small risk that the nerve itself may be damaged in which case there may be an increase in pain rather than a reduction. As with any injection, there is a very slight chance of getting an infection where the needle is placed. Every effort is made to avoid this with use of skin-cleaning solution, sterile gloves and equipment. The procedure is made as safe as possible by being performed by an experienced pain doctor who constantly monitors you throughout the procedure. X-rays may also be used to help guide the needle into the correct position. You may discuss the risks further with your pain doctor

Pre-operative assessment & Care

If you become pregnant, have any major illnesses/hospital admissions or start taking anticoagulant drugs (for example warfarin or clopidogrel) discuss this with the pain doctor before the procedure. If you have diabetes, you may need to make some changes to your diabetes medicine or diet on the day of the procedure. You should discuss this with your pain doctor before your procedure.

On the day of the procedure:

Follow the instructions given to you by the Day Surgical Unit staff about when last to eat or drink.

  • Take all your usual medication including your painkillers
  • Bring all your usual medication, or a list of what you are taking with you.
  • Make sure that someone will collect you, take you home, and is available to stay with you overnight.

During the procedure

At the Day Surgical Unit your pain doctor will see you and explain the procedure fully. Before the procedure starts a small cannula (tube) will be placed in a vein in the back of your hand through which we can give you medicines and fluids if that becomes necessary. You will be given medication (sedation) to make you feel sleepy during the injection. An oxygen mask will be placed over your face. The procedure takes about 15 minutes. After the procedure your blood pressure, pulse and respiration rate may be checked. After the procedure – what to expect For some people, the nerve block may not reduce their pain at all. It may make the pain worse. You may feel weak or tired for a little while after the injection so we advise that you rest for 24 hours. During this time you should not: drive a car or operate equipment, sign any legal documents or drink alcohol. You should continue taking your usual medication and the next day you may take a bath, or shower, and remove any plasters. Please contact your GP (family doctor) if you have any other symptoms causing you concern and if:

  • There is unusual redness or swelling at the injection site ·
