無菌技術（Surgical Asepsis）的核心是確保無菌物品僅接觸無菌區域。越過無菌區（Reaching over the sterile field）會造成潛在汙染，因為護理人員的衣服、手臂或皮膚上的微生物可能掉落至無菌區，造成破壞無菌屏障（Break in sterile technique）。
The core principle of surgical asepsis is ensuring that sterile items contact only sterile areas. Reaching over the sterile field creates potential contamination because microorganisms from the nurse's clothing, arms, or skin may fall onto the sterile field, resulting in a break in sterile technique.
