As a Surgical Technologist, you perform essential tasks before, during and after operations. You work closely with surgeons, anesthesiologists, registered nurses and other key surgical personnel in hospital operating rooms and outpatient surgery centers. Surgical Technologists play a critical role in patient care. (From reference #1)

The role of the Certified Surgical Technologist.

Before the operation, the CST prepares the OR by supplying it with the appropriate supplies and instruments. Other preoperative duties include adjusting and testing equipment, preparing the patient for surgery, and helping to connect surgical equipment and monitoring devices. The CST, usually the first member of the OR team to "scrub" and put on gown and gloves, prepares the sterile setup for the appropriate procedure and assists other members of the team with gowning and gloving.

During the operation, CSTs have primary responsibility for maintaining the sterile field. In order that surgery may proceed smoothly, CSTs anticipate the needs of surgeons, passing instruments and providing sterile items in an efficient manner. As directed by the surgeon, CSTs may sponge or suction the operative site, prepare suture material, dispense appropriate fluids and drugs, and prepare specimens for subsequent pathologic analysis.

After the operation, CSTs are responsible for applying dressings and preparing the OR for the next case.

CSTs may also function in the nonsterile role of circulator. This can involve keeping a written account of the surgical procedure, assisting the anesthesiologist, and helping account for sponges, needles, and instruments before, during, and after surgery. With additional specialized education and training, the CST may function as the surgical first assistant. (From Reference #2)
