Flashcards in Wound Care (Lab Info--Teri) Deck (32):
1

Primary Dressing

-material used to cover wound
-often to control exudate, prevent environmental contamination

2

Secondary Dressing

-material used to cover/secure primary dressing
-may or may not be sterile

3

Requirements for Optimal Wound healing

-optimal moisture
-get necrotic tissue out
-fill dead space
-protect periwound skin
-manage wound bacteria (bioburden)
-protect and insulate

4

Purposes of Secondary Dressing

-protect injured area
-hold splint/primary dressing in place
-exert pressure to prevent/decrease edema/bleeding
-support (sling)
-limit motion
-maintain body heat
-decrease blood supply (tourniquet)

5

Purposes of Primary Dressing

-decrease contamination potential
-absorb fluid
-apply medication to wound
-keep area warm

6

6 Helpful Hints in Dressing Selection

1. identify purpose of proposed treatment
2. consider wound-related factors
3. consider product-related factors
4. consider patient-related factors
5. avoid complications

7

ID purpose of dressing (11)

1. produce rapid and cosmetically acceptable healing
2. remove/contain odor
3. reduce pain
4. prevent/combat infection
5. contain exudate/drainage
6. debridement
7. cost
8. minimum distress/disturbance to pt
9. compression
10. pressure distribution
11. safety

8

11

Wound Characteristics

-dry
-moist
-heavy drainage
-malodorous
-excessively painful

17

Debridement Types

-non-selective (mechanical)
-selective
-sharp

18

Non-Selective Debridement

-Mechanical
-whirlpool, wet-to-dry, pulsed lavage, ultrasound mist, scrubbing

19

Selective

-Autolytic
-Enzymatic
-BIosurgical

20

Sharp

-scalpel, scissors, forceps
-conservative: remove dead tissue
-surgical: into live tissues

21

Autolytic Debriedement

-uses own enzymes to break down nonviable tissue

22

Enzymatic Debridement

-topical ointments use enzymes to break down non-viable tissue while preserving healthy cells

23

Biosurgical debridement

-sterile maggots

24

Physical Agents, Mechanical Modalities and other Adjunctive Interventions

-compression wraps
-E-stim, US, UV agents

26

Secondary Dressings:
Cylindar

-neck, trunk, wrists, lower legs, fingers, toes

27

Secondary Dressings:

-recurrent
-figure 8

30

Indications for Ace Wraps

-edema
-varicose veins

31

Edema

-distal to proximal
-leave toes (ex.) visible to check circulation
-may leave heal open to wear shoe

32

Varicose Veins

-elevate to drain first
-equal pressures
-overlap exactly 1/2 with each turn
