無菌技術的核心在於維持區域清潔並避免污染。由遠處開啟無菌包可防止身體接觸污染；手部維持腰部以上高度是確保視野清晰與避免誤觸的原則；將物品丟擲至無菌區中央則可保持邊緣無菌。跨越無菌區會導致無菌物品被污染。
Proper sterile technique involves opening packages away from the body to prevent contamination, keeping sterile items above waist level as anything below is considered unsterile, and dropping sterile items gently into the center of the field. Reaching over the sterile field or touching edges with non-sterile gloves compromises sterility.
