Surgical Site Infections (SSIs) are infections that occur at or near the surgical incision site within 30 days of an operation. They can happen after any type of surgery, including orthopedic, cardiac, or abdominal procedures. SSIs can be caused by bacteria entering the body during surgery, leading to symptoms like redness, swelling, and pain at the incision site. Preventing SSIs involves proper hygiene practices, such as cleaning the skin before surgery and using sterile instruments. Additionally, healthcare providers may prescribe antibiotics to reduce the risk of infection. Timely identification and treatment of SSIs are crucial to ensure patient recovery and prevent complications.
