Difference between Medical & Surgical Asepsis
|
Medical = "clean technique" (a decrease in microorganisms)
Surgical = "sterile technique (no microorganisms) |
|
What should you do with your gloves and alcohol wipes if the pt is under isolation precautions?
|
Take them out of your pocket if they are there and put them on bedside table.
|
|
Equipment - Sterile Wound Dressing Change
|
* Kit w/ 1 pr gloves, 4x4 gauze (1 2-pk), Q-tips, Tape (paper), Saline, 2 pr gloves, measuring device
- from kit, throw out: drape, curlix, gauze * Packing: - Kit - nacho plate, 4x4s, tapes, 1 pk Q-tips, ABD, 1 pk gloves - outside kit - 1st set gloves, measuring device, tape, 1 pk Q-tips, saline |
|
Maceration (w/ regard to condition of surrounding tissue)?
|
moisture (like prune fingers after a bath)
|
|
Excoriation (w/ regard to condition of surrounding tissue)?
|
scratches of the epidermis
|
|
Erythematous (w/ regard to condition of surrounding tissue)?
|
redness
|
|
3 ways to classify wounds?
|
1) intentional or unintentional
2) Open or Closed 3) Acute or Chronic |
|
Most common Chronic wound?
|
Pressure Ulcer
|
|
What's the defining characteristic of "un-approximated" wounds?
|
jagged edges
|
|
What to assess on a wound?
|
- approximation of edges
- integrity of sutures/staples - redness (erythema) - discoloration - warmth - swelling (edema) - unusual tenderness - drainage - surrounding tissues - maceration, excoriation, erythematous |
|
Primary Intention (in relation to wound healing)
|
Intentional closed wound (closed incision lines)
Intact incision line Dry, sterile dressing |
|
Secondary Intention (in wound healing)
|
Intentional or unintentional open wound
- Incision line re-opens - Inf. surgical wound/contaminated traumatic wound Sterile dressing change |
|
Tertiary Intention
|
Intentional or unintentional open wound (left open from the beginning - can see wound bed)
- Large surgical defect - Major trauma or burns - Sterile saline dressings - Possible skin grafting |
|
When & why would you leave a wound open?
|
In a secondary or tertiary intention.
Because it needs to heal from the inside out or it can increase r/o repeat infection. & prevents abscess. |

|
Difference between medical & surgical asepsis?
|
-Medical asepsis = clean technique (decreases micorganisms)
-surgical asepsis = sterile technique (NO microorganisms) |
|
Most solutions are considered sterile ______ hrs. after they are opened? (if closed for further use)
|
24 hrs
|
|
What are typical ways to classified wounds?
|
-intentional or unintentional
-open or closed -acute or chronic |
|
Most common wound?
|
pressure ulcer
|
|
What kind of wound is one with jagged edges? Example?
|
unapproximated (pressure wound)
|
|
Describe a “primary intention” wound.
|
-closed, incision lines intact
-dry, sterile dressing |
|
Describe a secondary intention wound.
|
-infected, incision reopens, etc (needs intervention)
-requires a sterile dressing change - usually moist→dry & leave it open |
|
Why would you leave the Secondary intention wound open after re-dressing?
|
needs to heal inside→out or can ↑ r/o infection
|
|
Describe a tertiary intention wound. Why would it be used?
|
-left open from the beginning (can see wound bed)
-Used for large surgical defect -major trauma or burns - sterile saline dressings - possible skin grafting - used to prevent an abscess |
|
Factors affecting wound healing?
|
-Age
-circulation & oxygenation -nutrition & hydration -health status |
|
Things used to drain a wound? Describe them.
|
-Open drain
- Penrose drain – acts as a sinus/pathway -Closed drain - Jackson-Pratt (JP) – pulls out drainage w/ negative pressure - Hemovac – Accordian style |
|
Why can let a Jackson-Pratt drain fill completely?
|
negative pressure will be gone
|
|
When would a Hemovac be used?
|
hip or mastectomy
|
|
What care should be taken when draining a ventricle, CSF, etc?
|
drain slowly
|
|
How are wounds describe by color?
|
- red: healing = protect
- yellow: infected or draining = cleanse - black: necrotic (aka. eschar) = debride - also “sloughing” wound = dying tissue falling off |
|
Examples of “mechanical” wound treatment?
|
-moist to dry dressings
-irrigation by whirlpool or syringe |
|
Example of “chemical” wound treatment?
|
Proteolytic enzymes – eat dead tissues
|
|
Pressure ulcer stages:
|
1) Red, non-blanching, skin in tact
2) Open blister – no epidermis, see dermis 3) Adipose tissue visible 4) underlying structures visible (muscle, bone, etc.) 5)unstageable – eschgar on wound |
|
What is granulation tissue & what is the best environment for it?
|
healthy tissue, moist environment
|
|
4 words for describing wound drainage?
|
1) Serous = clear, watery
2) Purulent (infected) = thick, yellow, green, tan (cloudy) 3) Serosanguineous = pale, red, and watery 4) Sanguineous (fresh) = bright red, active bleeding |
|
Why is a purulent drainage cloudy?
|
due to the presence of white blood cells/
What does “Dehiscence” refer to in wound complications? *opening of wound layers (muscle intact) |
|
What does “Evisceration” refer to in wound complications?
|
protrusion of internal organs (muscle separated)
|
|
What is a “Fistual formation”?
|
abnormal opening from organ→organ or organ→skin
|
|
What could cause a Fistula?
|
chemo Tx
|
|
What is the first nursing action with an Evisceration?
|
-Do NOT leave the pt., keep moist but don’t be concerned with sterile at that moment (organ already outside of body)
-position in low fowler’s -cover wound with sterile towels moistened w/ 0.9% NaCl solution |
|
Basic principals of Surgical Asepsis?
|
-open package away from you
-do NOT pour liquid onto cloth or paper field (unless plastic backed) -Keep sterile objects in sight & above waist & below shoulders -avoid creating air currents (stirs up fomites) - close door or curtains - limit talking, do not cough or sneeze |
|
What should be monitored?
|
- excessive drainage that may overwhelm dressing
- change soiled or loose dressing |
|
What considerations can be taken for older adults with ↓ skin elasticity & ↑ sensitivity?
|
-paper tape
-roller gauze on extremity dressings - skin protectant (hydrocolloid dressing) under tape -montgomery straps – for excessively changing dressings (heavily draining) |
|
What if the dressing is dry upon removal?
|
reduce the time between changes to prevent drying of the materials (may disrupt healing tissue)
|
|
When removing a pt’s dressing, the assessment reveals eschar in the wound?
|
notify PCP or specialist to consult about different Tx or possible debridement.
