外科無菌技術（Surgical Asepsis）的核心在於維持無菌區域的絕對無菌狀態。護理師必須確保所有無菌物品皆在視線範圍內，且低於腰部高度的物品被視為受污染，因為護理師的視線可能無法全程監控。此外，開啟無菌包裹時，應背對無菌區以避免身體接觸或飛沫污染。這些原則是為了防止病原體進入病人的手術部位或無菌組織，從而降低手術部位感染（SSI）的風險。
Correct surgical asepsis requires keeping sterile items within the nurse's line of sight and above waist level, as anything below the waist is considered contaminated. Additionally, opening sterile packages away from the body minimizes the risk of contaminating the inner contents with clothing or respiratory droplets.
