Wound Classification Flashcards
What are 4 classifications of operative wounds?
- Clean
- Clean-contaminated
- Contaminated
- Dirty
What is an example of a clean wound?
Surgically created wound
With what type of wound has no infection been encountered, aspetic technique been maintained and no structure normally containing bacteria has been opened?
Clean wound
A surgically created wound where a hollow viscus or organ normally containing bacteria is opened but no contents are spilled is considered what?
Clean-contaminated
If a minor break in aseptic technique occurs this can create what type of wound?
Clean-contaminated
A surgical wound where a hollow viscus is opened with gross spillage is considered what?
Contaminated
A major break in technique can cause what type of wound?
Contaminated
A traumatic wound is considered to be what?
Contaminated
If a wound contains pus or contents of perforated hollow viscus, it is considered to be what?
Dirty
What is the goal of aseptic technique?
Minimize the incidence of surgical wound infection.
The risk of infection doubles with what duration of time with surgery?
Doubles every 70-90 minutes of surgery.
What is the rule of thumb for the risk of infection in reference to time?
Risk doubles every hour.
What is the incidence of surgical wound infections with clean procedures?
0 - 4.4%
What is the incidence of surgical wound infections with clean-contaminated procedures?
4.5 - 9.5%
What is the incidence of surgical wound infections with contaminated procedures?
5.8 - 28.6%
What is the incidence of surgical wound infections with dirty procedures?
Implies infection
What are 4 sources of operative wound infections?
- Operating room environment
- Operating team
- Surgical instruments and supplies
- Patient’s endogenous flora
What is the most common source of operative wound infection?
Patient’s endogenous flora
Surgical site infection can occur up to how many days post-surgery?
Up to how long with implants?
- Within 30 days
- Up to 1 year
What should the use of antibiotics and surgery be based on?
Based on sound principles and established benefit.
Antibiotics are often overused/misused, increasing the risk of what?
Risk of developing antibiotic resistant strains.
What is not a good substitute for good surgical technique?
Antibiotics
What are 2 ways to use antibiotics for surgery?
- Prophylactic
- Therapeutic
What can be used if the risk of infection is high or an infection would have catastrophic results?
Prophylactic antibiotics
When are prophylactic antibiotics administered?
Prior to induction for surgery
How soon before a skin incision is made for surgery are prophylactic antibiotics administered?
30-60 minutes prior to skin incision.
What are the 2 most commonly used antibiotics with surgery?
- Cefazolin
- Cefoxitin
How can post-operative infections be minimized?
Good nursing care practices.
