How often should surgical masks be changed?

1. Every hour

2. After each case

3. Every two hours

4. At the end of the day

The correct answer is: After each case

Surgical masks are vital for maintaining a sterile environment during surgical procedures, as they help to prevent the transmission of infectious agents between the surgical team and the patient. It is crucial to change surgical masks after each case because they can become saturated with moisture from breathing and can collect contaminants. A mask that has been worn for a prolonged period or has been used in a procedure may not provide adequate protection due to its compromised integrity or potential contamination. Changing the mask after each case ensures that the surgical team is using a clean, effective barrier for the next procedure. This practice is part of strict infection control protocols in the operating room, as it minimizes the risk of post-operative infections and protects both the patient and healthcare staff. While frequent changes may seem cumbersome, they are a standard practice to maintain optimal safety and sterility throughout the surgical process.
