無菌技術（Sterile technique）的目的在於預防醫源性感染。無菌區（Sterile field）要求所有進入該區域的物品必須無菌，且不可有非無菌物越過。手或非無菌物品越過無菌區會產生落塵或接觸污染。正確操作包括：包裝開啟時邊緣不可觸碰無菌面，保持無菌區在視線範圍內以防無意間接觸，以及嚴格遵守 1 吋（2.5 公分）邊界非無菌的概念。一旦無菌區被污染，必須視為無菌技術破壞。
Reaching over a sterile field breaks sterile technique because airborne particles may contaminate the area, and accidental contact can transfer microorganisms. Maintaining the field within sight, keeping a 1-inch non-sterile border, and opening packages away from the body are correct practices to preserve sterility.
