Surgical and OR prep and conduct in VETC 247
Show Answers:

  1. sterile
    free from bacteria or living microorganisms
  2. aseptic technique
    • used to maintain absense of disease-causing organisms in surgical environment
    • used to maximize asepsis.  
    • protect from infection
  3. scrubbed in
    person who has gone through process of scrubbing hands and forearms and gowning and gloving in preparation for surgery
  4. contamination
    disruption of sterility in a field prepared aseptically.
  5. strikethrough
    contamination of sterile field via liquid soaking through barrier drapes
  6. bair hugger
    warming measure in surgery, runs warm air around patient
  7. sterile field
    • a specified area that is considered free of microorganisms
    • Prepared aseptically
    • encompasses drapes upward, outer inch is considered nonsterile
    • contaminated by reaching across or getting wet
  8. how long do packs remain sterile?
    • single-wrapped are sterile for up to a year in a  closed cabinet
    • double-wrapped can be stored for 2 years in a closed cabinet.
  9. Surgery prep of patient
    • clip hair/fur at surgical site with generous borders.  
    • +/- dirty scrub
    • transfer to OR
    • set up P in OR
    • aseptic scrub
  10. scrubbing
    • dirty and aseptic
    • dirty removes gross debris after clipping

  15. strategies for limb suspension/tieback in surgery/prep
    • 1. glove on tip of limb, wrap glove in tape, tape strip up one side, down the other, stirrup, tape around the ends, hang with stirrup so you can prep all around, then surgeon can grab with drape
    • 2. suture through toe webbing, cut off needle and tie a loop, suspend.  Good for distal surgery
    • 3. babcock forceps, grab webbing and lock closed.  Tape one side of forcep handles so you can open them
