Topic: NPWT, what happens at a dressing change and how family can help
If someone in your family is on a wound pump, the dressing changes happen every two to three days. Here is what to expect, and how you can make it easier.
What happens at a change
🔹 The pump is switched off and the canister and tubing are checked
🔹 The old drape and foam are removed slowly. If the foam has stuck, a little saline softens it first
🔹 The wound is cleaned and looked at properly: size, depth, the tissue in the base, the fluid and the skin around it
🔹 It is measured, and photographed with consent, so progress is recorded and not guessed
🔹 The surrounding skin is protected, a new piece of foam is cut to size, the drape is sealed and the pump goes back on
🔹 The seal is checked before the nurse leaves. The foam should shrink and go firm
It usually takes 30 to 60 minutes.
Is it painful? It can be uncomfortable, especially when the foam comes out. Pain relief about 30 to 60 minutes before the change, if the patient uses it, makes a big difference. Always tell the nurse if it hurts. There are ways to make it easier.
How family can help
🔹 Have a clean, clear surface ready near the bed, and good light
🔹 Keep pets and children out of the room for the change
🔹 Have the next canister and charger nearby
🔹 Write down anything you noticed since the last visit: alarms, leaks, pain, fluid changes, fever
🔹 Ask to be shown how to check the seal and what the alarms mean, if you have not been shown already
A good dressing change is a partnership between the nurse, the patient and the family. The family often notices things first.
