Communicable infection Only the top of the table with the … Sepsis  5,6 Additionally, surgical personnel should work together as a team to problem solve the break in technique and arrive at the optimal decision applying the principles of asepsis. Conversely all materials and equipment used during a surgical procedure are terminally decontaminated and sterilized after use with the assumption that every patient is a potential source of infection for other persons. The circulator is responsible for opening a sterile package using aseptic technique to prevent contamination of the enclosed sterile item(s). In sterile technique, all microorganisms must be maintained at an irreducible number, meaning as low as absolutely possible.
