無菌原則（Principle of asepsis）的核心在於維持無菌區域（Sterile field）的完整性，防止微生物污染。無菌區域必須全程在護理師的視線範圍內，一旦離開視線，即無法確認是否被污染，必須視為受污染。此外，無菌區應保持在腰部以上、清潔乾燥，且避免呼吸道飛沫污染。臨床上，安全優先原則要求若無法確認無菌狀態，則應視同污染並重新準備，以確保病人安全。
The principle of asepsis requires maintaining the integrity of the sterile field by keeping it within the nurse's direct line of vision at all times. If a sterile field leaves the line of sight, it cannot be confirmed as uncontaminated and must be treated as such to ensure patient safety.
