My Spine - Lumbar
How does it work?
As soon as you feel pain, you press the button (or the lever) on the handset.
This is connected to the PCA machine (or PCA syringe) and you will hear a
bleep (with the electronic PCA) to confirm that the machine is working. It
will then deliver a small amount of painkiller into your drip. This acts quick-
ly and also avoids the need for painful injections.
Does the machine always give painkiller when I press the lever?
No. It only gives painkiller every few minutes (usually seven), however many
times you press the button. This is to ensure that one dose has had time to take
effect before another dose is given and to avoid complications such as sup-
pression of your breathing.
Can I have an overdose of the painkiller?
PCA is generally very safe and can provide good pain relief, which is bene-
ficial to your recovery. You will be regularly observed while you are on the
PCA. It is important that only you (not relatives or friends) press the button
(or lever) and only for pain from your operation site.
Will I get addicted?
No. Addiction does not happen when you are taking painkillers for a few days
to treat pain from an operation, no matter how much you need.
How often should I press the lever?
You need to press the lever as often as you require to keep yourself comfort-
able. You should use as much painkiller as necessary to allow you to move
around comfortably, take a deep breath and cough (this is important to clear
secretions from your lungs). There is no need to refrain from using the PCA
analgesia, as it is completely safe.
