1

What to debris?

slough and eschar to minimize growth of organism

2

What is non selective debridement

removes necrotic and living tissue
no way of telling what you are taking out wound, may be taking good and bad tissue

3

Examples of non selective debridement?

wet to dry dressings
chemical
water debridement

4

Indications of of non selective

-infected wounds
-wet slough
->70% nerotic tissue
-stop whirlpool when >30% granulating tissue

5

What is semi-selective debridement?

viable and non viable tissue removed

6

What does semi-selective debridement remove?

loose, mobile nonadherent slough

7

What do you use for semi-selective debridement?

sharps, stop if bleeding; contraindicated if arterial wound and anticoagulants

8

Four reasons why you should stop debridement?

Bleeding
patient requests
fatigue
inexperience

9

What kind of debridement is it if no viable tissue is distrubed?

selective

10

Two types of selective debridement:

enzymatic (chemical to break down specific components) and autolytic

11

What are 3 specific enzymes used in debridement?

Collagenase (digests collagen and is slow)
Papain and Urea (digest fibrin and is banned)

12

What is autolytic debridement?

natural enzymes in wound fluids are contained under synthetic dressings, allowing macrophages and engulf necrotic tissues (contraindicated with infection)

13

What are advantages of Calcium Alginates?

-with infection
-deep wounds
- light to mod exudate
- easily removed
Disadv: maceration

14

Semipermeable films

-transparent
-permeable to moisture vapor and oxygen
- impermeable to bacteria and water
-idea for minimul exudate
- covers stage I or II

15

Semipermeable Foam

- moderate to high exudate
- not transparent
- not for infected wounds

16

Impermeable Hydrocolloids

impermeable to water, bacteria, oxygen, other gases
anaerobic healing
-expands as it absorbs
-high levels of exudate

17

What compound is effective against SA, MRSA and Pseudomonas?

Silver

18

What is active against gram positive infections?

Mupirocin

19

How many mmHg of pressure would be on a venous ulcer compression?

at least 30

20

What is hemociderine

red color that forms on wounds

21

On arterial ulcers do not

elevate or sharp debride

22

What should you apple silver sulfadiazine to?

trunk burns

23

Facial burns apply:

neomycin, bacitracin

24

autograft

person

25

allograft

another person

26

xenograft

animal

27

Culture:

not good
