This page contains valuable information about a peripheral nerve block (lower limb). However if you still have questions after reading it, please ask your doctor or other health professional for more details.
A peripheral nerve block is an injection given to numb the nerves in the leg. It is a form of regional anaesthetic and is typically administered with other painkillers.
You can receive a nerve block while you are conscious, sedated, or alongside a spinal or general anaesthetic. For leg operations, it is likely you will receive either a spinal or general anaesthetic. In such cases, a nerve block may be given as an addition to the anaesthetic for pain relief following the operation.
There are five areas where the injection can be administered: behind the knee or thigh, in the foot or ankle, or near the groin.

The anaesthetist will need to locate where to place the injection. This is usually identified using a nerve stimulator and an ultrasound scanner.
The injection of anaesthetic will be made using the identified entry site. The anaesthetist may also insert a small tube with the needle which can remain in position for future anaesthetic applications.
A peripheral nerve block is a safe way of providing a patient with pain relief.
