How to Use SertaSil

Watch our three videos, which describe in detail how to use Amicapsil and SertaSil. The principles are identical as they are both based on MPPT. The first video covers the first day of use and the subsequent two, how to continue the use of until wound closure. Activate subtitles by pressing on CC.

Debride the wound as much as possible and wash the wound thoroughly with water.

Most common error:

The wound is not washed thoroughly. It needs to be rinsed for several minutes with tap-water at a good pressure.

Dab the wound dry with a clean gauze swab.

Most common error:

The wound should not be completely dry. Apply SertaSil while the wound surface and the surrounding skin are still moist.

Sprinkle a 1-3 mm layer of SertaSil on to the entire wound surface including edges, sinuses, tunnels and beneath undermining.

Most common error:

The layer of SertaSil should be unbroken and must cover the wound edges. Use a finger to rub a thin layer into any affected skin around the wound.

Cover with a very light, fully permeable secondary dressing. In difficult to dress areas the secondary dressing can be omitted but this may require a few extra applications, as the SertaSil will be at risk of being worn off.

Most common error:

Air must be able to circulate across the wound surface. SertaSil uses the force of evaporation to function and, without this, it will not work. Do not use synthetic dressings – only woven 100% cotton gauze swabs.

Three videos showing how SertaSil can be applied to a dog paw and how the paw can be dressed when inside and outdoors.


Repeat this procedure daily until the wound shows no signs of infection or necrosis.
In non-chronic wounds this will on average will be 3 days.

Examples of the surface of a wound on which the use of SertaSil can be ceased:

Dressed wound: moist clean surface.
Dressed wound: moist clean surface:
Wound on which secondary dressing was omitted: dry flexible (scab free) clean surface: (or as a dressed wound)

After SertaSil

After ceasing the use of SertaSil the wound should be dressed as above and left completely undisturbed to heal.

The dressing can be changed weekly or biweekly – unless the wound gets wet as that would prompt a wash and dressing change.

  • SertaSil has not been associated with wound irritation or contact sensitisation (allergy).
  • The components of SertaSil have not been found to cause toxicity.
  • SertaSil is not absorbed by the body.
  • SertaSil can be removed by simple irrigation with water.

The longer version

1 Remove dirt, pus, dead tissue, slough, and very old scabs or other evidently inappropriate material from the wound.
2 Wash the wound with plenty of clean tap water. A wash-bottle, or alternatively a large syringe, will allow a good cleaning pressure. If you prefer, you can use saline. Do not use antimicrobials such as antiseptics or antibacterial rinsing solutions or soaps for rinsing.
3 Gently dab the wound dry with a gauze swab.
4 Sprinkle SertaSil in an even layer 1-2 mm thick, directly onto the entire wound surface. This includes the visible area, all crevices, beneath loose flaps of skin and any undermined areas, all sides of the wound and all surfaces lining any tunneling. Cover the wound edges well, extending to an area 5 mm from the wound edge, onto the unbroken skin surrounding the wound opening. If the area surrounding the wound area is red and inflamed, very gently rub SertaSil into the red area.
5 To keep the SertaSil in place on the wound, cover it with a lint-free woven 100% gauze swab and fasten it along the edges using sticking plaster tape. If the wound is covered with SertaSil all over the surface, the gauze will not stick to the surface.
6 Daily, remove any pus and dead tissue (yellow slough) with a moist gauze. Then wash with plenty of tap-water, preferably using water from the shower head to clean out all corners and crevices. Then apply SertaSil and a covering dressing as described above.
7 The day there is no more yellow slough on the wound surface and there is no exudate on the secondary dressing upon removal, discontinue the use of SertaSil. Just wash the wound in the shower without touching the wound surface. Dab it dry very gently. Apply a N-A dressing from Systagenix, not the N-A Ultra and not a different dressing with NA in its name. Repeat this daily until full closure.
8 As healing progresses, flakes or scales or wafer-thin crusts are likely to appear on top of the wound and in the area of unbroken skin surrounding the wound. This is a sign of healing and regeneration of tissue taking place in the skin as well as the layers underneath the skin. Don’t remove these. They will fall off in their own time. The area might appear dry, it may even seem too dry, but it isn’t. Don’t touch the flakes. They will fall off by themselves when the skin underneath is ready. Don’t apply and creams or ointments.
9 If you for some reason inhibit the access of air to the wound, for example by applying a different dressing on top of the healing wound after no longer needing the SertaSil every day, you may one day experience that there is a bit of exudate stuck to the dressing when you remove it – similar to what you experienced while first applying SertaSil. This is an indicator that the healing process, that had been initiated by SertaSil , has been impeded. Apply SertaSil as before, usually for 1 day, and continue as before. If your wound is very old, it is advised to avoid this situation and keep the healing process going without any interference until full closure, e.g. by providing the optimal healing conditions.
