無菌技術（Sterile technique）的原則在於維持物品與操作區域的絕對無菌。無菌布的邊緣（約 2.5 公分）被視為「無菌邊界（Sterile border）」，一旦被非無菌物體碰觸，即視為污染。新進護理師若未戴無菌手套直接碰觸該區域，則無菌包裝已受污染，必須重新執行程序，這是保護病人免受醫源性感染的基本要求。
Touching the edge of a sterile drape with non-sterile gloves constitutes a break in sterile technique because the one-inch border is considered contaminated. Proper practices include opening packages away from the body, keeping the sterile field above waist level, and maintaining constant visual contact with the area.
