無菌技術（Sterile technique）的目的在於建立並維持無菌區。無菌區的邊緣一英寸（約 2.5 公分）被視為「污染邊界」，因為該區域可能接觸到非無菌面或在設置過程中受污染。護理人員在操作時，必須嚴格維持此邊界並僅觸碰無菌手套的內側，確保無菌用品不被污染。此外，無菌區必須在視線範圍內，一旦背對或離開視線，即失去無菌狀態。
Proper sterile technique requires maintaining the integrity of the sterile field, where the outer one-inch border is considered contaminated. Nurses should only touch the inner aspects of sterile items or the non-contaminated surfaces, ensuring the field remains within their direct line of sight to prevent accidental contamination.
