Having a plaster put on and taken off
Most of the fear about plasters is not about wearing one — it is about the saw used to take it off. It is worth explaining how that saw works, because once you understand it the noise stops being frightening.
What people worry about
The saw will cut my skin.
It cannot cut the way you are imagining.
The blade does not spin. It vibrates rapidly from side to side, through a very small distance. It cuts hard plaster because plaster cannot move away from it. Skin is soft and flexible, so it moves with the blade instead of being cut.
Ask us to run it against our own palm in front of you before we start. We do this routinely, especially for children. It takes ten seconds and it changes the whole experience.
It is loud and it gets warm. Neither of those is dangerous, and we stop if it becomes uncomfortable.
The plaster is getting hot. Something is wrong.
Plaster warms as it sets. That is chemistry, not a problem.
It becomes noticeably warm for a few minutes while it hardens, then cools. We use cool water and we do not rest a setting plaster on a pillow, both of which keep the temperature down.
Tell us if it becomes genuinely hot rather than warm.
I should push something down inside to scratch the itch.
Please do not — this is how serious wounds happen under plaster.
A knitting needle, a pen or a stick can scrape the skin, and you will not see the wound for weeks. Under a plaster, that can become a deep ulcer or an infection.
Tap the outside of the plaster, or use a hairdryer on the cool setting blown into the end. If the itching is unbearable, come and see us.
A tight plaster just means it is doing its job.
No. Increasing tightness and pain is the one thing you must never ignore.
Pain under a plaster is never normal if it is getting worse. A limb swells after an injury, and a plaster that fitted at midnight can be dangerously tight by morning.
Elevate the limb and take a painkiller. If the pain is still increasing, come in — at any hour. Splitting a plaster takes thirty seconds and we would far rather do it for nothing.
What actually happens
A stockinette and padding go on first 3 minutes
A soft layer that protects the skin, with extra over the bony points.
The plaster is applied wet and moulded 5–8 minutes
We shape it with the palms of our hands. Holding still matters here — the shape is what holds the bone, not the strength of the material.
It sets and warms 5–10 minutes
It becomes warm, then cools and hardens.
We check the fingers or toes 1 minute
Colour, warmth, feeling and movement — and we write it down. You should be able to move them.
You are given the warning card 2 minutes
What to watch for and when to come back. Take a photograph of it with your phone.
Removal, weeks later 2 minutes
The saw, a spreader, then scissors through the padding. Noise and warmth, no cutting.
