HOW DO I PREPARE THE ULCER BEFORE APPLYING THE 3C PATCH®?
After debriding, rinse, and/or swab until any bleeding has stopped. On subsequent treatments, rinse with water and remove any loose residual 3C Patch®. If the 3C Patch® is integrated into the newly formed granulation tissue, do not remove it.
If the wound area has not changed over a few weeks, it may be necessary to perform another debridement before the 3C Patch® is placed on the wound.
WHAT SIZE OF ULCER CAN I TREAT?
There is no minimum size. Each device produces a 5cm² patch. The patch can be cut to size to treat smaller wounds.
HOW MANY 3C PATCH® TREATMENTS ARE NEEDED?
This varies from patient to patient and from wound to wound. In general, you can expect to see an effect after 2-3 applications.
Data from our Cohort study (Wagner Grade I and II DFU) gave a mean treatment time to healing of 11 weeks (11 weekly treatments) with a range of 3-20 weeks.
Data from the RCT study gave a mean treatment time of 10 weeks to healing, so 6-8 or more applications are not unusual to create new granulation tissue.
IS THERE A MAXIMUM NUMBER OF APPLICATIONS?
We recommend continuing the 3C Patch® treatment as long as you can see an effect from the 3C Patch® treatment every week.
CAN THE 3C PATCH® COME INTO CONTACT WITH INTACT SKIN?
WHAT DO I DO IF THE 3C PATCH® IS VERY MOIST?
WHAT DO I DO IF THE 3C PATCH® IS VERY THICK?
WHAT DO I DO IF THE 3C PATCH® IS VERY THIN?
CAN I TREAT DEEP ULCERS, INTERDIGITAL ULCERS OR ULCERS WITH EXPOSED TENDONS OR BONE CONTACT?
CAN I USE SEVERAL LAYERS OF 3C PATCH® ON TOP OF EACH OTHER IN DEEP ULCERS?
WHAT DO I DO IF THE ULCER IS UNDERMINED?
IF THE PERIWOUND SKIN IS MACERATED, WHAT DO I DO?
absorbent secondary dressing. The goal is to create a moist wound healing environment while avoiding too much moisture or even wetness.
HOW DO I PLACE 3C PATCH® INTO THE WOUND?
HOW MUCH OF THE WOUND AREA NEEDS TO BE COVERED BY 3C PATCH®?
CAN I CUT THE 3C PATCH® INTO SHAPE SO IT FITS TO THE ULCER?
HOW LONG WILL THE GROWTH FACTORS BE RELEASED IN THE ULCER
HOW IS THE PRIMARY BANDAGE APPLIED?
Make sure not to cover the entire primary dressing with tape as fluid needs to be able to pass.
Do not remove this primary dressing between the weekly treatments at the hospital/clinic.
It is acceptable to lift the dressing and observe for infection in the wound during the week and of course to replace the secondary dressing if needed.
CAN I USE SILVER AS PRIMARY DRESSING?
WHICH SECONDARY DRESSING CAN BE USED?
HOW OFTEN DO I HAVE TO CHANGE THE SECONDARY DRESSING?
CAN THE PATIENT TAKE A BATH BETWEEN TREATMENTS?
Yes; however, please use water-proof protection to avoid wetting the primary and secondary dressing.
If the 3C Patch® has been placed in the wound for 3-4 days before the primary and secondary dressing is compromised, growth factors have been released. In this case, remove both dressings and replace them with a fresh absorbent dressing until the next visit to the clinic.
Please instruct the patient to notify the clinic of this occurrence.
CAN I USE NWPT (NEGATIVE WOUND PRESSURE THERAPY) COMBINED WITH 3C PATCH®?
CAN I USE A COMPRESSION BANDAGE COMBINED WITH 3C PATCH®?
– and change the secondary dressing accordingly.
CAN THE 3C PATCH® BE STORED OR REFRIGERATED?
CAN I TREAT A PATIENT WITH AN INFECTED ULCER?
ARE THERE ANY CONDITIONS FOR WHICH TREATMENT WITH 3C PATCH® IS CONTRAINDICATED?
WHAT IS THE TREATMENT FREQUENCY WITH 3C PATCH®?
WHAT IS THE PATIENT SELECTION CRITERIA?
NO BLOOD IS DRAWN INTO THE 3C PATCH® DEVICE
THE DEVICE IS NOT COMPLETELY FILLED
In the 3CP® Centrifuge User manual section 5.3.4, underfilled device, you will see photos of devices, which show which fill level is acceptable and which is not.
HOW LONG AFTER DRAWING THE BLOOD SHOULD THE CENTRIFUGATION BEGIN?
DOES WARFARIN (OR MAREVAN) AFFECT THE COAGULATION TIME?
coagulation is prolonged.
WHAT DOES INR VALUE MEAN?
• If you have an INR of 1 the coagulation (gel-like layer) will normally form within a 10 min. coagulation phase.
• If you have an INR value of 2 it generally means that coagulation time is double.
• If you have an INR value of 3 it would generally triple the time of the coagulation phase.
DOES XARELTO (RIVAROXABAN) AFFECT THE PREPARATION OF THE 3C PATCH®?
If appropriate, investigate with the clinician if it is possible for the patient to delay the intake of Xarelto until after the blood sample for 3C Patch® preparation is taken.
Please note that the Xarelto treatment does not increase your INR value but coagulation could still be prolonged.
