A Surgical Site Infection (SSI) is defined as an infection that occurs postoperatively at the site of a surgical operation. This type of infection can develop in the skin, tissues, or organs involved in the surgical procedure and may manifest within days to weeks after the surgery.

Understanding the nature of SSIs is crucial for patient care, as they can lead to extended hospital stays, increased healthcare costs, and even more serious complications if not addressed promptly. The risk factors for SSIs include a patient's overall health, the type of surgery, and adherence to sterilization protocols during the procedure.

The other options do not accurately describe SSIs. While infections can occur during surgical procedures, they are not universally commonplace, and their occurrence is not simply an expected part of surgery. Additionally, SSIs are not always easily treated with antibiotics—treatment may require more than just medication, including wound care or additional surgical procedures. Lastly, while complications can arise due to anesthesia, an SSI is specifically related to infections at the surgical site, not anesthesia administration.
