Sterile technique (surgical asepsis)
|
Designed to keep areas completely free from microorganisms (sterilization)
|
|
Clean technique (medical asepsis)
|
Prevent the spread of microorganisms (hand hygience, barrier techniques PPE, routine cleaning
|
|
Sterile technique is routinely performed in
|
OR, Labor and deliverly, Cardiac Cath Labs, GI Labs, patients bedside
|
|
When is Sterile technique is used at the bedside
|
1. procedures that require perforation of pts skin (insertion of IV)
2. integrity of skin is broken (incision or burn) 3. procedures that involve inserting devices into sterile body cavities (insertion of urinary cathater) |
|
Before performing sterile technique
|
Assess patient
(comfort, oxygen requirements, elimination needs, pain, confusion (may need assistance), least amt of ppl in room) dont set sterile field until assessment is complete. check expiration dates |
|
Principles of surgical asepsis
|
All items on sterile field must be sterile
sterile barrier that is permeated by moisture is considered unsterile Drapes are only allowed 1 inch border to touch (unsterile) only sterile at table level do not flip or throw objects on sterile field only sterile persons can touch sterile items field must always be in view only set up sterile field immediately before procedure, perform assessment first |
|
Gowns are sterile
|
From waist to chest
anything held below waist is considered unsterile |
|
When using bottles during a sterile procedure
|
Check for tears moisture & expiration date
invert caps label bottles with date & time of opening (only able to be used for 24 hrs before considered contaminated) |
|
Strike through
|
Splashing liquids causes fluid permeation of the sterile field, resulting in contamination
|
|
Categories of wounds
|
Surgical, trauma, diabetic, venous, arterial, pressure
|
|
Surgical wound
|
From surgery, staples or sutures present, may become dehisced (seperated, not approximated)
|
|
Trauma wound
|
Caused from an outside force (laceration, puncture, abrasion)
|
|
Diabetic wound
|
Diabetics have decreased sensation in lower extremities and poor wound healing.
lower extremity ulcers are common (may not notice if a shoe doesnt fit and can develop an ulcer that doesnt heal) |
|
Venous wound
|
Faulty veins due to cardiovascular disease
superficial ulcer on skin, can get DVT treated with compression stockings after wound heals more red and edema than arterial wound |
|
Arterial wound
|
More yellowish than venous from arterial blockage
usually pale and cool, decreased pulse and lack of oxygen and circulation to extremity |
