Q

what are the primary functions of hydroactive dressings?

A

(1) highly absorbent
(2) provide moist environment
(3) semipermeable to water vapor (control moisture in wound bed)
(4) can expand and contract shape with motion

17
Q

what are the indications of hydroactive dressings?

A

(1) moderate to heavy exudate
(2) LE ulcers (venous ulcers)
(3) pressure injuries
(4) wounds around joints

18
Q

how do blood glucose levels affect wound healing?

A

elevated blood glucose levels stiffen arteries and cause narrowing of blood vessels (causes diabetic wounds and affect proper wound healing)

19
Q

how does diabetes affect wound healing?

A

(1) decreased blood flow causes reduced oxygen to the wound
(2) elevated blood glucose decreases the function of RBCs carrying nutrients; also reducing efficiency of WBCs that fight infections
(3) this reduced blood flow and nutrients causes a wound to heal slowly

20
Q

what is the number 1 reason for limb amputation in the US?

A

diabetes (secondary to gangrene)

21
Q

how does nutrition play a role in burn management and improve survival rates?

A

(1) enteral nutrition with glutamine preserves mucosal integrity
(2) parental nutrition via IV with 5% dextrose and 5% albumin

22
Q

what are two quick ways to estimate the extent of burns? (2)

A

(1) Palmar Method

(2) Rule of 9’s Method

23
Q

what is an accurate and quick method for estimating the extent of burns?

A

Lund-Browder

24
Q

what are the different grades of burns based on depth?

A

(1) superficial
(2) superficial partial thickness
(3) deep partial thickness
(4) full thickness

25
Q

when is a skin graft required for burns?

A

a full thickness burn >1 cm

26
Q

what is used when <30% of the total body surface area (TBSA) is burned?

A

split-thickness auto or allograft skin barriers

27
Q

what is used when >40% of the total body surface area (TBSA) is burned?

A

allograft, xenograft, or synthetic coverings (auto grafts can be used but require 1-2 weeks to heal at the donor site)

28
Q

what is used when >90% of the total body surface area (TBSA) is burned?

A

up to 10 cycles of auto-grafting may be required

29
Q

why and how are patients immobilized following a graft surgery?

A

(1) must be immobilized to limit shear forces

(2) patients are splinted so the affected joints are at a maximum stretch

30
Q

what do musculocutaneous flaps provide to a wound?

A

(1) physiological barrier to infection
(2) eliminate dead space in the wound
(3) improve vascularity

31
Q

what are the physiological effects of e-stim with negative polarity on wound healing? (3)

A

(1) attracts lymphocytes (reduces infection)
(2) simulates fibroblasts
(3) decreases edema

32
Q

what are the physiological effects of e-stim with positive polarity on wound healing? (2)

A

(1) macrophage activity (wound debridement)

2) decreased scar thickness (via decreased mast cells

33
Q

how does TENS affect wound healing?

A

can induce vasodilation thus increasing tissue oxygenation
