Quick Overview

Scope of Practice (ScOP) Designation

Aim of Dressing

Safely remove the vac dressing from the 5 day old split skin graft (SSG) that was placed in surgery. The ssg may stick to the interface dressing which is why time and patience is required when taking down this dressing.

Tips & Tricks

1) Turn the Vac off 30min before removing the vac to allow to vac foam to separate from the SSG as much as possible 2) Slow and steady wins this race 3) Using the BACK of the forceps you can push down the skin graft if it rises a small amount when removing the vac foam

Tutorial Steps

 Swipe 
Step 1: Remove the vac film from the patient's skin (DON'T touch the graft)

Turn the vac off 30min before attending to the dressing

Step 2: Slowly lift the foam and cut it in a line so that it can lift off the SSG

Slowly lift and cut the foam making sure the scissors are not near the SSG

Step 3: Slowly remove the foam from the interface dressing (the dressing between the SSG and the vac foam)

Slowly peel back the foam. This may mean using normal saline and the sue of sterile forceps (see step 4)

Step 4: Use the BACK of the forceps to aid you to keep the SSG stuck to the wound bed

Using the BACK of the sterile forceps push any SSG that rises off the wound bed back down carefully.  The technique is lift the foam slightly and then sneak the back of the forceps between the foam and the interface dressing and push the SSG down. DO NOT lift the foam a large amount and then reactively push the graft back down. This will only make the SSG bunch up.

Step 5: Clean the SSG

Using sterile MOUTH SWABS saturate them with normal saline and then roll (NOT scrub) over the SSG. This has a double action of cleaning the SSG as well and pushing it down onto the wound bed.

General Notes

What have we learnt:

1.Always have the patient laying in bed as it will take a while

2.Turn Vac off over 30min before attempting to take the dressing down

3.Due to the graft being circumferential I had to cut the initial part of the vac foam VERY carefully. If this was just a single area you could peel the vac foam off whilst watching out for any staples that maybe anchoring it

4.Make sure your patient has some pain relief. This particular patient has chronic pain

5.Leave excess blood or excess dried skin graft attached and allow it to fall off in time
