When should an endoscope be sent for terminal sterilization?

An endoscope should be sent for terminal sterilization when it has been used in sterile environments or for invasive procedures. This is crucial because these settings require a higher level of microbial kill to ensure patient safety and prevent infections. Invasive procedures expose tissues directly to instruments, necessitating that any residual bacteria or pathogens are completely eradicated to avoid complications.

While routine disinfection processes are vital after every use, they may not suffice for an endoscope that has been involved in procedures where sterility is paramount. Terminal sterilization ensures that any potential pathogens are eliminated, thus upholding the strict standards of care in clinical settings. The need for sterilization is particularly critical in situations where endoscopes are used on compromised patients or during surgeries that breach the body's barriers.
