wound classification Flashcards
what is a clean wound?
surgically created wound where there is no infection encountered and aseptic technique has been maintained
what is a clean-contaminated wound?
surgically created wound in a hollow viscus organ or an organ that normally contains bacteria is opened but no contents are spilled
- or a minor break in asepsis may have occured (ex. hole in glove)
what is a contaminated wound?
- surgical wound that has gross spillage from a hollow viscus or a major break in asepsis occurs
- traumatic wound
what is a dirty wound?
contains pus or contains contents of a perforated hollow viscus
what is the goal os aseptic technique?
minimize the incidence of surgical wound infection
true or false.
The risk of infection doubles with every 70-90 minutes of surgery
true, rule of thumb is that risk doubles every hour.
what are the 3 things that differentiate infection from inflammation?
- present of purulent discharge
- abscess
- fistula
what are the 3 major risk factors for infection during surgery?
- duration of surgery
- increasing number of people in the OR
- dirty surgical site
what can we do to try to protect against infection from surgery?
antibiotic prophylaxis
what is classified as a surgical site infection ?
infection at surgical site occurring within 30 days of surgery or up to a year with implants
when do we use prophylactic antibiotics?
- when risk of infection is high or if infection would have catastrophic results
- administered 20-60 minutes prior to surgery or wound contamination
- can be continued intraoperatively
if using antibiotics intraoperatively, how often should they be given?
every 90-120 minutes
when should we use therapeutic antibiotics?
- when a systemic infection is present
- infection present at surgical site or in body cavity
- contaminated or dirty procedure
- should be based on culture and sensitivity
