外科無菌技術（Surgical asepsis）要求嚴格的無菌區域管理。無菌區域的邊緣（通常定義為邊緣 1 英吋或 2.5 公分）被視為污染區，因為它們靠近非無菌的桌緣。此外，任何低於腰部或低於無菌檯面的物品均被視為受污染，且無菌野必須全程有人看管。護理師在操作時必須時刻保持警覺，避免任何無意間的污染動作。
In surgical asepsis, the outer 1-inch border of a sterile field is considered contaminated because it is close to non-sterile surfaces. Additionally, any item below waist level is treated as contaminated, and sterile fields must remain under direct observation at all times to maintain sterility.
