1
Q

turgor:

A

The degree of elasticity of skin, sometimes referred to as skin turgor. The assessment of skin turgor is used clinically to determine the extent of dehydration, or fluid loss, in the body.

Q

perfusion:

A

is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue, usually referring to the delivery of blood to a capillary bed in tissue. The word is derived from the French verb “perfuser” meaning to “pour over or through”.

A

Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. Granulation tissue typically grows from the base of a wound and is able to fill wounds of almost any size.

A

Wound dehiscence is a surgical complication in which a wound ruptures along a surgical incision. Risk factors include age, collagen disorder such as Ehlers–Danlos syndrome, diabetes, obesity, poor knotting or grabbing of stitches, and trauma to the wound after surgery.

Q

slough:

A

Slough is defined as yellow devitalized tissue, that can be stringy or thick and adherent on the tissue bed. This wound bed has both yellow stringy slough as well as thick adherent slough. Slough on a wound bed should be surgically debrided to allow for ingrowth of healthy granulation tissue.

Q

Infants skin:

A
  • Lanugo and vernix caseosa at birth(thin,smooth,elastic)
  • infants skin is inefficient at birth but improves with growth, since the skin is thin, and subcutaneous layer is thin,it is more permeable to heat and fluid loss.
  • infants pigment system is also immature.

Q

Older adults skin:

A
  • Loss of elasticity caused by loss of elastin, collagen, and subcutaneous fat.
  • Layers thin and flatten- it becomes wrinkly and tears more easily
  • decreased gland function causes dry skin
  • fragile, unsupported vessels
  • hair-melanocyte function decreases and leads to grey hair
  • these changes in the elderlys skin causes decreased protection, decreased temp regulation, decreased ability to repair, less ability to absorb and secrete, and decreased vitamin D production

BRADENS scale:

A

-you don’t just perform and record: this is a call to action!
facilities will have a policy of when to do a Bradens scale and what to do with the results
*it is an interactive tool: you need to interact with the person to collect the data
*when in doubt of rating, use lower score
* theres is a Braden Q-pediatric version, which has an added tissue perfusion and oxygenation category- which looks at blood pressure and O2 stats
Limitations of Bradens scale includes that it doesn’t count previous or present pressure ulcers, and doesn’t document cognition
Norton scale and Waterloo Scale are similar scales, less commonly used
