Epidural anaesthetic at Shrewsbury Hospital

The anaesthetic numbs the nerves to give you pain relief in various areas of your body.

Epidurals can be used either on their own while you are awake, or together with sedation or general anaesthesia.

They can also be used after your operation to give effective pain relief. The epidural can be maintained by giving extra doses when needed or by giving a continuous low dose.

How is epidural anaesthesia administered?

You will meet with the anaesthetist prior to your procedure and he/she will be with you throughout your time in theatre. Staff will assist you getting into a curled up position on a bed. You might be asked to bend forward and hug a pillow or to lie on your side curled up with your knees drawn toward your chest. We understand this can be an anxious time so staff will be with you to reassure and support you during the injection.

Local anaesthetic will be injected into a small area of the skin on your back. The anaesthetist will use a needle to insert a thin plastic tube (epidural catheter) into your epidural space. The needle is then removed. A small amount of anaesthetic will be inserted through the catheter to check it is in the right position. Once this check is completed the anaesthetist will inject more of the drug until the epidural is working properly.

Will I feel anything?

The local anaesthetic might sting briefly. You might feel pressure or movement when the catheter is inserted. Occasionally patients feel an sensation described as an electric shock or pain. Tell the anaesthetist immediately if this happens.

As the epidural begins to work the lower part of your body will feel very heavy. You will not be able to move your legs.

Epidurals can be used both during and after a procedure for pain management. The epidural catheter will be removed once your pain is managed. The numbness and weakness in your legs will gradually decrease over the day following your procedure. For your safety please ask for help before getting out of bed or moving around.
