無菌技術（Sterile technique）旨在消除微生物，防止醫源性感染。根據無菌原則，無菌區上方空間視為無菌範圍，任何跨越（Reaching over）該區的動作，皆可能導致衣物上的皮屑、細菌或空氣中的微粒落下污染無菌區。護理師必須確保無菌操作過程中，所有動作均位於腰部以上且在視線範圍內，避免背對無菌區或跨越之風險。
Reaching over a sterile field contaminates the area because pathogens from the nurse's clothing or skin can fall onto the sterile surface. Sterile items should be added from above without crossing the field, and packages should be opened away from the body to maintain sterility. Keeping the field within eyesight ensures that accidental contamination is avoided during the procedure.
