無菌技術（Sterile Technique）的核心在於維持無菌區的完整性。無菌區的邊緣一英吋（約 2.5 公分）被界定為「污染邊界（Contamination Border）」，因為此區域可能已與非無菌表面接觸，或在打開包裝時被污染。將非無菌物品放置於此邊界內，不會影響中心區域的無菌狀態。其他操作均會導致無菌區失效，進而增加手術部位感染的風險。
The outer one-inch border of a sterile field is considered a contaminated zone because it may have contacted non-sterile surfaces or been compromised during package opening. Placing non-sterile items on this border preserves the sterility of the central field, whereas touching inner drapes, opening packages toward oneself, or keeping fields below waist level violates sterile technique.
