Q

U.S. Guaze

A

• Tested and proven hypoallergenic – safe for patient use w/ any skin type
• USPVII (US Pharmacopeia’s Standard) – often “exceeds” the national standards set
o Testing includes: Chemical purity, thread count, absorbency, sterility, etc…
• Machine Folded vs. Hand Folded – Limited human hands leads to less risk of contamination
• US Cotton Crops Rotated – no slash/burn technique means no risk of p.domesticum
• Tested for endotoxin/pyrogen levels (dead cellular bugs) – less debris and risk of contamination provides cleaner, safer gauze
• Manufacturing is rotor spinning – less debris and higher levels of absorbency
• Air jet loomed – virtually no friction – less lint and better chance of blowing out debris

Q

Import Gauze

A
  • Usually “meets” USPVII standards.
  • Fields are slashed/burned – elevates risk of p.domesticum, a mold found in the burned residue in soil, can only be killed by steam sterilization
  • Questionable Agricultural Practices – fertilizing, harvesting, shipping/handling of crops
  • Higher levels of endotoxin/pyrogen levels (dead cellular bugs) – debris increase risk of contamination
  • Manufactured with Ring Spun Technique – potentially traps debris and offers less absorbency
  • Shuttle Loomed – Friction caused by Shuttle = increased lint

Q

U.S. vs Import Gauze: Talk Track

A
  1. Cotton is grown as a plant – talk about crop rotation vs. slash/burn, questionable fertilization techniques in china
  2. Harvested cotton is spun into thread – discuss F/B of rotor vs. ring spinning
  3. Thread is woven into a fabric – discuss F/B of air jet loomed vs. shuttle loom
  4. Fabric is folded and cut into dressings – discuss F/B of hand vs. machine folding
  5. At this point you check for customer buy-in/agreement that US dressings are clinically superior.
  6. Next you address financial implications that can occur from using sub-par dressings..specifically addressing the “silo” talk track
  7. And this gives you a lead in to explain our blended strategy approach.

Q

Dermacea

A

value brand gauze
• Cost savings alternative
• Made in China, using either Winner or Allmed (company that Medline uses) =if they use medline product, Dermacea will be clinically acceptable.
• Consistency – only using two mfgs in China
• Sterility – all Dermacea products are steam sterilized, steam is the only way to kill p.domesticum
• Absorbency – we are not as absorbent as our American line, but just as absorbent as all the other Chinese brands….at least we are up front about that and offer two options.
• Blended Strategy Approach

Q

Blended Strategy

A

Customer is adamant about saving money in TWC. You can use Curity for those codes being used in direct patient contact, and use Dermacea for the non-clinical codes… Promotes cost saving, but doesn’t sacrifice patient care.

Q

Two types of adhesive technology?

A
  1. Hotmelt (medline) - starts with a solid “block” of glue, adhesive is applied by direct coating at high temps, then cured by rapid cooling (hot glue gun).
  2. Solvent (3m, Kendall) - acrylic adhesive applied through polymer disbursement, substrate given a “bath” on one side, adhesive cured by heating at high temps.

What are the 4 stages of wound healing?
1. Debridement 2. Granulation 3. Epithelialization 4. Maturation
26
Debridement
The wound area is cleared of dead tissue and debris before healing commences.
27
Granulation
The volume is filled in by new dermal like tissue.
28
Epithelialization
New epidermis migrates across the wound
29
Maturation
New epidermis and new dermis mature in structure and become functional.
30
What are the four different types of Ulcers?
1. Diabetic- caused by trauma or pressure related to the neuropathy or vascular disease associated with diabetes. 2. Venous Statis- Occurs over or near ankle joint, cause by edema and impaired venous blood return. 3. Arterial- Caused by ischemia (deficient blood supply to tissue) 4. Pressure- Ischemia caused by pressure
31
Stages of Pressure Ulcers?
Stage I - intact skin, non-blanchable redness Stage II- partial thickness, shallow open ulcer or serum filled blister Stage III- full thickness, subcutaneous visible Stage IV- full thickness, exposed bone, tendon, or muscle. Unstagable- full thickness, base of ulcer is covered by slough or eschar so you can't gauge depth.
32
What are the 5 types of Debridement?
1. Autolytic- Body's self digestion by action of enzymes present in wound fluids 2. Biological- Sterile maggots 3. Enzymatic- Chemical debridement by use of enzymes. 4. Mechanical- Physical force such as wet to dry dressings, wound irrigation, or whirlpool. 5. Sharp- Scalpel, laser.
33
Moist Wound Healing (MWH)
- Conceptualized in 1960 - Epithelial cells need moisture to migrate and spread - MWH wounds heal quicker, scar less, have less pain. - MWH is a balance between giving moisture and absorbing excess to prevent maceration.
34
Kendall Foam: Softness
3x softer than market leading allevyn products. | -Provides maximum patient comfort
35
Kendall Foam: Absorption/Fluid Capacity
Most absorbent foam in market. - Leads to longer wear times - Less expense - As it absorbs fluid, foam is pulled down into wound bed to fill dead space and help promote healing.
36
Kendall Foam: Small Cell Size
Outer surface of foam is made up of small cells to reduce the chance of tissue migration into the dressing. -Causes trauma upon dressing removal
37
Kendall Foam: Application & Use
Partial thickness wounds, skin tears, abrasions, lacerations, ulcers, draining wounds.
38
Kendall Foam: Competition
Allevyn, Lyofoam, Ploymem, Mepilex, Optifoam.
39
Kendall Foam: Talk Track
-Positioned as the "Ultra-soft foam wound dressing with super absorption and superior feel". Kendall Hydrophilic foam dressings provide ideal moist environment for variety of wounds.This highly absorbent, non-linting dressing is designed to protect and cushion moderate to heavily exudating wounds. Kendall Foam Dressings are semi-occlusive allowing the exchange of gases such as oxygen and water vapor. Its soft, flexible nature allows the dressing to conform easily to all body contours. Kendall Foam Dressings are non-adherent, making dressing changes easy and comfortable. Kendall Foam Dressing with Top Sheet features polyurethane top sheet in yellow, pairing super absorbency with effective strike-through prevention. It is also available in Island, Fenestrated and various sizes and can be cut to accommodate hard to dress areas.

TWC Call Points
start with DON, find out if WOCN has a say in this decision, bring materials in for financial/logistical discussions for conversion
41
AWC Call Points
start with the WOCN, bring in materials for financial/logistical discussions on a conversion
42
AMD Call Points
start with the ICP, decide how dressings will be used you may need to bring in WOCN or Key Physicians, always bring in materials for financial/logistical conversations on a conversion • WOCN – main goal is healing/treating wounds • ICP – looking for products that lower infection rates, prevent infections
43
Gram Staining
turns bacteria color to help differentiate them into two large groups, gram-positive and gram-negative, generally gram-negative bacteria are more dangerous disease organisms
44
Log Counts
are used when counting bacteria because of the large number that can be in a specific small area, it’s on a base 10 scale
45
Log Reduction
10x reductions of bacteria
46
Infection
log count of 10^5 or higher
47
Colonization
Log count of 10^3 | -Organisms are present, but not at a high enough log count to begin causing disease or infection

5 AMD Claims
- Effective against gram + and gram - bacteria - Prevents bacterial growth and penetration through dressing - Does not negatively impact epithilization - Barrier function may help to reduce infections in partial and full thickness wounds - 510k clearance for sale of AMD as both primary and secondary dressing
62
AMD Contraindications
- AMD should NOT be used with Dakin's solution, or bleach solutions - Use of PHMB and Dakin's (or bleach solution) deactivates and neutralizes the polymer.
63
AMD Product line - 6 TWC - 2 AWC
1. Kerlix AMD Rolls 2. Kerlix AMD Super Sponges 3. Telfa AMD Dressings 4. Excilon AMD Drain Sponges 5. Curity AMD Packing Strips 6. Curity AMD Gauze Sponges 7. Kendall AMD Foam 8. Kendall AMD Foam Disc
64
AMD Foam Sheet
- Foam is impregnated (not coated) contains .5%PHMB - Mode of action=foam absorbs wound fluid, PHMB binds to foam material and kills bacteria. - Open cell microstructure has highly absorptive contact surface with dense core for fluid retention. - Effective for 3-7 days
65
AMD Foam Disc: 3 differences compared to competitors
- non-oriented, either side can be applied to wound. - hypoallergenic, not cytotoxic, and non-irritable. - Cost effective...$4/5 each on most contracts.
66
AMD vs. Silver
- Both have same FDA claim - Silver is priced at premium - AMD has no change in protocol. - Silver may elude and overwhelm the wound causing it to stain the wound bed - Silver is not effective in killing the multi-drug resistant bacteria (Acinetobacter Baumannii) - Silver dressings are commonly thought of as treatments, not prophylactics b/c they are expensive
67
AMD Proticol
o No additional training for any nurses to apply it correctly, so there’s no learning curve o It’s a great product for home health use, as it’s easy for patient’s to apply themselves o Can be used moist or dry and does not need to be activated o AMD can be used with virtually any dressings except Dakins.
68
Silver Proticol
o Moistened and kept moist in order for the silver to release/elude. o You cannot use saline to moisten a silver dressing….sterile water only. Salt in the saline neutralizes the silver. o Silver dressings have complicated instructions…usually are oriented (one side goes up or down), if you don’t use the correct side, the dressing is useless. The waste of these dressings is very costly. o Silver cannot be used with Santyl.
69
AWC Foams:
-moisture balance for wound healing, cushioned to protect against pressure. o Kendall Foam – plain, topsheet, drain sponge, gentle adhesion (silicone) o Copa Island – border o Softest, most absorbent on the market
70
AWC Transparents
-Typically used to secure IV sites, PICC lines, etc. o Kendall Transparent Dressing (polyskin) o Window transparent dressing (WTD) o Clinical performance of tegaderm with a potential cost savings
71
AWC Hydrogels
-donate moisture back to the wound o Kendall- amorphous gel, impregnated gauze, and disc o Unique glycerin formula means thicker gel, less chance for it to run out of wound….Aquaflo has unique disc shape for elbows & heels, etc…
72
AWC Hydrocolloid
-promotes autolytic debridement o Kendall – sheet, border, and sacral o 30% alginate gives dressing integrity to keep it from melting into wound
73
AWC Calcium Alginate
-Conforms easily and absorbs high amounts of fluid. o Kendall- rope, sheet, and ZN (zinc) o Made from the stem of seaweed, not leaf so it is stronger than competition, less chance of having it break apart or needed to be irrigated out of wound
