A sterile field is a designated area that is free from all microorganisms, including bacteria and viruses. It is essential in medical settings, particularly during surgical procedures, to prevent infections. The sterile field is created using sterile drapes, instruments, and supplies, ensuring that anything that comes into contact with the surgical site is clean. Maintaining a sterile field requires strict protocols. Healthcare professionals, such as surgeons and nurses, must wear sterile gloves, gowns, and masks. They must also avoid touching non-sterile items and follow specific techniques to preserve the sterility of the area throughout the procedure.
