What is a peripheral nerve block?
The nerve block can last from 2 to 36 hours depending on the injection site and type of local anaesthetic used. During this time, you may feel the following: numbness, tingling, weakness or inability to move your arm or leg. Usually, the weakness wears off first followed by return of sensation.
Until normal sensation has returned:
Protect your limb from excessive heat or cold and avoid placing it in abnormal positions.
Keep your leg or arm well supported, avoiding excessive pressure.
Do not mobilise without support if your nerve block involves the foot or leg.
Avoid doing things for example, using machinery which could injure you while you cannot feel your limb.
If your pain is not controlled by the pain relief given, please seek medical help or visit your nearest A&E.
If your nerve block injection was performed near your collar bone, neck or chest wall and you experience severe breathlessness, please contact emergency services, or visit your nearest Accident and Emergency (A&E) department.
You may be contacted by hospital staff after your discharge to check on your wellbeing. If you have not been contacted but you continue to have numbness or weakness in your limb after 36 hours, please contact the hospital switchboard on 01642 850850 and ask for the anaesthetics registrar on call.
