Q

DIMES- infection and topical interventions; ionic vs colloidal silver

A

ionic silver
-protects the wound from bacterial contamination

colloidal silver
-silver deposits into tissues; blue skin appearance

Silver as an element has proven to be antibacterial and protective against a lot of different kinds of germs and bacteria. Wound healing using silver ions works very efficiently even in low concentration and has been proven to cause faster healing than usual.

Q

What is a hemovac?

A

A Hemovac drain is placed under your skin during surgery. This drain removes any blood or other fluids that might build up in this area. You can go home with the drain still in place.

Q

What is a Jackson Pratt Drain?

A

-held into place with 1-2 stitches internally

-must be under suction

-must unplug, squeeze, replug

JP drains are often placed in wounds during surgery to prevent the collection of fluid underneath the incision site. This is a closed, air-tight drainage system which operates by self-suction. The drain(s) promote healing by keeping excess pressure off the incision and decreasing the risk of infection.

Q

Electrical stimulation-indications and CIs

A

Type used:
-high volt
-low intensity- direct current
-microcurrent
** evidence supporting pulsed current, TENS, and PEMI

INDICATIONS
-chronic or recalcitrant (not healing in typical timeline) wounds, clean or infected, granular or necrotic
-pressure, arterial, venous, or neuropathic
-better outcomes for pressure wounds than venous ulcers

CONTRAINDICATIONS
-wounds with osteomyelitis, in combination with topicals containing heavy metal ions, actively bleeding wounds; caution w/patients with sensory neuropathy
-caution with cancer, DVT, pregnancy

HOW IT WORKS
-necrotic tissue has disrupted polarity–> E stim helps to restore the current of injury (bioelectric field and polarity)
-enhanced epithelialization
-stimulates cells to move along an electrical gradient (galvanotaxis)
-stimulates cell proliferation
-Increases blood flow (augmented angiogenesis)
-increased oxygen at wound bed
-Increases bactericidal abilities (attraction of neutrophils and macrophages)
-reduces edema
-facilitates (autolytic) debridement

*electrodes can be placed within wound bed

(thrombo-embolytic deterring device) –> prevents DVT, NOT edema

  • TEDs provides10 mmHg at popliteal vein –> does not prevent DVT when working against gravity (better in supine)

SCDs- sequential compression devices
–> standard DVT prevention combined with anticoagulation

34
Q

What intervention should be avoided with venous wounds?

A

whirlpool

35
Q

Arterial wound intervention:

A

-with dry gangrene:
–> may auto amputate
–> offload wound
–> educate on auto-amputation, home care, signs/symptoms, emergent nature of conversion to wet gangrene
–> educate on feet protection, protect from extreme temps, protect open wounds, control medical cons, exercise regularly, quit smoking, eat balanced diet, keep nails trimmed straight, clean and smooth socks, avoid constrictive clothing, well-fitting shoes, protect and moisturize surrounding skin

  • a lower ABI can lead to decrease in global strength, decrease in global endurance, decrease in SL balance
36
Q
