無菌技術（Aseptic technique）的目的是在進行侵入性操作時，徹底消除微生物進入體內的風險。在進行導尿管置入時，從準備階段開始，任何環節若違反無菌原則，都可能導致尿路感染（CAUTI）。打開無菌包（Sterile kit）是建立無菌區域的起點，若此步驟受污染，後續的操作將全部失效，因此該步驟必須嚴格執行無菌操作。
Strict aseptic technique is mandatory when opening the sterile kit because it establishes the sterile field for the invasive procedure. Any contamination during this initial step compromises all subsequent supplies and significantly increases the risk of catheter-associated urinary tract infection (CAUTI).
