無菌技術（Sterile technique）旨在防止微生物污染。無菌區（Sterile field）必須始終保持在護理師的視線範圍內，若物品離開視線，即視為已被污染。此外，無菌包裝的邊緣（通常為 1 英吋內）被視為不潔區，跨越無菌區上方會因空氣流動或皮屑掉落導致污染，因此所有動作必須在無菌區上方進行且保持警覺。
Maintaining sterile technique requires keeping all sterile items within the nurse's direct line of vision at all times to ensure they have not been contaminated. Items that leave the visual field are considered unsterile, just as touching the one-inch border of a sterile field or reaching over it with non-sterile attire would violate aseptic principles.
