無菌技術（Sterile Technique）要求護理師對無菌區域保持 360 度的監控。無菌區域一旦超出護理師的視線範圍，或護理師轉身背對它，該區域即被視為可能遭受污染，因為無法確保無菌狀態未被破壞。臨床實務中，護理師應始終面向無菌區，確保所有無菌物品在視線範圍內，並嚴格遵守無菌邊緣（1-inch border）的非無菌區定義。
Sterile technique requires the nurse to maintain 360-degree visual supervision of the sterile field. Once the sterile field is out of the nurse's line of sight, or once the nurse turns away from it, the field is considered potentially contaminated because its sterile status can no longer be assured. In clinical practice, the nurse should always face the sterile field, keep all sterile items within sight, and strictly observe the 1-inch border as non-sterile.
