Surgical technologists are the first people to enter the operating room before a surgery. They prepare and sterilize the location and layout all needed equipment, taking a careful count of everything being used. Once everything is sterile and prepared, the surgical tech acts as an aid for the surgeon and surgical assistant. While continuing to maintain the sterility of the room, they may also be asked to help prep and give medications, assist with retraction of tissues from the patient, and pass instruments to the surgeon as needed. Postoperatively, surgical techs count every tool and device used once again, to ensure nothing was left inside the patient. They may also help with sutures and to disinfect the incision site. Finally, they help with the proper disposal of all gauzes, drapes, and syringes.
