預防手術部位感染（SSI）的核心是無菌技術（Sterile Technique）。在更換大型腹部滲液傷口敷料時，若操作不符合無菌原則，極易將環境中的細菌帶入傷口，導致嚴重的深層感染。因此，即使是更換敷料，也必須嚴格執行無菌操作（如正確洗手、使用無菌紗布、不接觸傷口處）。這比定期換藥、預防性抗生素更具根本性的預防意義。
Strict sterile technique is paramount when changing dressings for large, draining wounds to prevent introducing microorganisms into the surgical site. While antibiotic administration and dressing coverage are important, maintaining asepsis during the procedure is the most critical intervention for preventing surgical site infections.
