Nerve block This is an injection of local anaesthetic near the nerves which go to your leg . This will numb part of the leg and make it pain-free for several hours after surgery . You may also not be able to move it properly during this time .
Advantages You won ’ t need such strong pain relieving medication during and after your anaesthetic , and therefore won ’ t feel so sick .
You should be more comfortable for several hours after your operation .
Before coming to hospital
Risks The numbness and weakness may last up to 16-24 hours , delaying your ability to walk and do your exercises .
Rarely there is risk of damage to the nerves .
Blood products There is a small risk that you may need to have a blood transfusion . A transfusion of blood or blood products is only given when the benefits outweigh the risks .
You have the right to decide whether you want to have the treatment or not . You can ask as many questions as you need to ensure you are making the right choice .
You will be asked to sign a consent form to show that the benefits , risks and alternatives for your treatment , including transfusion of blood products , have been explained to you . The consent form will confirm that you have been able to ask any questions and you agree to receive the treatment .
If you refuse to have a transfusion when needed , the risks to your health are likely to increase .
