The primary purpose of surgical asepsis is to maintain a sterile field during invasive procedures. This practice eliminates all microorganisms to prevent contamination of the surgical site, thereby reducing the risk of postoperative infections. Maintaining sterility is critical because any breach can introduce pathogens directly into sterile tissues. Ensuring a sterile environment protects patient safety and promotes optimal surgical outcomes. Therefore, strict adherence to surgical asepsis principles is essential during all invasive procedures to prevent infection and complications.
