Q

Principles of surgical asepsis

A
  • sterile with sterile
  • partially unwrapped packaging is considered unsterile
  • if you question if its sterile, consider it unsterile
  • longer the time = less sterile
  • expiration dates
  • once an item is open its only a matter of time before it is contaminated
  • if item gets wet its contaminated
  • coughing,sneezing, or excessive talking over a sterile field contaminates it
  • dont reach over a sterile field
  • below waist level is considered contaminated
