無菌操作（Sterile Technique）要求嚴格遵守污染邊緣（Sterile Field Border）原則。無菌桌面的邊緣 1 英寸（約 2.5 公分）區域被視為受污染區域，因為該區域常被視為無菌與非無菌區域的交界。將無菌包放置於此，極易因觸碰或氣流導致無菌物品受污染。護理師需隨時監控學生的操作，確保無菌屏障完整，一旦發生污染，需立即重新執行程序。
Sterile technique requires strict observance of the sterile field boundary. The outer 1 inch (about 2.5 cm) of the sterile field is considered contaminated because it sits at the boundary with non-sterile surfaces. Placing a sterile package on the edge of the table contaminates it. Checking expiration dates, cleaning from center outward, and performing hand hygiene before the procedure are all correct.
