When should sterile technique be used?

The use of sterile technique is essential in situations where there is a risk of introducing pathogens into the body, particularly during invasive procedures. Placing sutures is a procedure that requires the skin to be incised, which creates an entry point for bacteria and other microorganisms. To prevent infection, a sterile technique must be employed, ensuring that all instruments and materials used are free from microorganisms and contaminants.

In contrast, administering medication orally, taking a patient’s temperature, and conducting a physical examination do not involve invasive procedures. These activities typically do not compromise skin integrity or internal tissues, so they do not require the same level of sterility as suturing does. Instead, they may require cleanliness or general hygiene practices rather than a sterile field. This distinction is crucial in medical settings to ensure patient safety and the effectiveness of the procedure.
