What does the term "strike-through" refer to in a sterile environment?

The term "strike-through" in a sterile environment specifically refers to the transfer of moisture from unsterile to sterile layers. This phenomenon occurs when a liquid, often blood or other bodily fluids, seeps through a sterile barrier, such as drapes or wrappers, and compromises the integrity of the sterile field. It is crucial in surgical settings to maintain strict sterility to prevent infections; if strike-through occurs, the affected area is considered contaminated and may increase the risk of surgical site infections.

Understanding this term is pivotal for surgical assistants and team members as it highlights the importance of assessing the conditions and integrity of sterile barriers during procedures. Maintaining a clear, dry sterile field is fundamental for achieving optimal patient outcomes.
