Which procedure or practice requires surgical asepsis?

I.v. cannula insertion-caregivers must use surgical asepsis when performing wound care or any procedure in which a sterile body cavity is entered or skin integrity is broken. to achieve surgical asepsis, objects must be rendered or kept free of all pathogens. inserting an i.v. cannula requires surgical asepsis because it disrupts skin integrity and involves entry into a sterile cavity (a vein). the other options are used to ensure medical asepsis or clean technique to prevent the spread of infection. the gi tract isnt sterile; therefore, irrigating a nasogastric tube or a colostomy requires only clean technique.
