Anaesthetic choices for hip or knee replacement (RCoA)
On this page…
As part of your operation you have had an anaesthetic nerve block to help your pain control. This may result in your arm or leg feeling temporarily numb and heavy. Keep yourself safe by checking these four things while on the ward or at home.
Slings, pressure points and scalding
Make sure your numb limb does not contact anything that could scald, and that it is rested on a soft surface to avoid pressure points. If applicable, keep your weak arm supported in a sling so that it does not suddenly drop.
Analgesia (painkillers)
Nerve blocks only provide temporary pain relief and will wear off. Be ready for this increase in pain by taking your prescribed painkillers at regular intervals when you are discharged, even if you are pain free at that time.
Falls
Your arms and legs are very important for your balance. As your limb may be temporarily paralysed you are at higher risk of falling than usual. You may also feel lightheaded after your surgery, so be careful when getting up!
