sterile package with the top flap set to open toward the person opening the pack.All drape items must be clean and dry.When opening and pouring sterile solutions: a. remove the cap and place it on a corner of the sterile field with the lid down. b. wipe up any spills of solution using a sterile towel. c. hold the bottle approximately 36 inches above the basin when pouring, to form a steady stream
