1
Q

When do we usually remove passive drains?

A

wound-dependent!

  • remove when amt of drainage steadily decreases or turns from
  • exudate—>transudate**

usu. 3-7 days

2
Q

How far from the incision should you plan the exit site in placing a passive (penrose) drain?

A

At least 1cm from incision
And slightly lateral

3
Q

T or F:
Precise quantification of drainage fluid is a major advantage of active drains.

A

TRUE

REMEMBER,
when removing a JP drain, consider:
_body produces 1-2mL per kg per DAY

remove drain when fluid production decreases to
less than 5mL per kg per DAY or =0.2mL per kg per HOUR_

4
Q

How should we treat highly contaminated wounds that cannot be treated via primary closure?

A

Open Wound Management (OWM)

5
Q

Which type of debridement is the most selective (only UNhealthy tissue removed)?

A

Autolytic:
performed by WBCs during the first 3-5 days after wound occurs

6
Q

How does bandage therapy promote an acid environment at the wound surface?

A

By preventing CO2 loss and absorbing ammonia produced by bacteria
(increases oxygen dissociation from hemoglobin and subsequently increases oxygen availability)

7
Q

What are some common intermediate (secondary) layer materials in a bandage?

A

Loose-weave, absorbent materials (cast padding, bulk roll cotton)

8
Q

What are some common outer (tertiary) layer materials in a bandage?

A

Porous surgical adhesive tape (Elastikon), elastic adherent or self-adherent material (vetwrap), and stockinette

9
Q

What type of bandage therapy is commonly used EARLY in the course of wound mgmt, but is NEVER indicated once granulation tissue develops?

A

Wet-to-dry;
goes on wet, wicks fluid (non-selectively) onto gauze

10
Q

What is the process of creating a wound env’t that optimizes the body’s inherent wound-healing abilities using specialized primary layers called moisture retentive dressings (MRD)?

A
  • *Moist Wound Healing (MWH)** -
  • wound fluid provides a physiologic ratio of proteases, protease inhibitors, GFs, cytokines at each stage of wound healing*
11
Q

What is currently considered the standard of care for wound management?

A

MRDs (Moisture retentive dressings)
as they are usually non-adherent and occlusive thereby protecting and retaining wound fluid

12
Q

____(quantity) Moisture vapor transmission rate (MVTR) strongly correlates w/ positive wound healing outcomes and is predictive of healing when all other variables are held constant.

A

LOW!
Dressings with an MVTR of =35 g/m2/hr are considered Moisture Retentive!!

13
Q

What are the Big 4/ Arsenal MRDs?

A

Calcium Alginate,
Polyurethane foam,
Hydrocolloid,
Hydrogel

14
Q

How frequently should you change MRDs during the inflammatory phase (most exudate)?

A

q2-3 days

15
Q

How frequently should you change an MRD once granulation tissue has formed?

A

q5-7 days

*change to a less absorptive dressing (i.e. hydrocolloid)*

16
Q

Studies conclude that, at _________ mmHg, NPWT increases blood flow to a wound, accelerates rate of granulation tissue formation, decreases bacterial counts, and improves flap survival

A

125 mmHg

_N_egative _P_ressure _W_ound _T_herapy
