What are some drawbacks of foam dressing?

A

They may produce a malodorous discharge
Require more frequent dressing changes than other dressings

115
Q

What do polymeric membrane dressings do?

A

Used in mildly exudative balloons, and stimulate growth of new epithelium
Do not stick into the wound bed, resulting in less, to granulation tissue

116
Q

What kind of dressing or wound care can be used for debridement of necrotized tissue and eschar?

A

Hydrogels

Q

What is the main advantage of hydrogels?

A

They can provide moisture drama, sure way to the wound, depending on the needs of the wound
They have a soothing effect and cause a little trauma to the wound bed

118
Q

What is one disadvantage of hydrogels?

A

May require frequent dressing changes

119
Q

What is a key benefit of using staples over sutures?
