| used to puncture tissue | teeth |
| instruments used for cutting and dissecting | curettes, scalpels, scissors |
| instruments used for grasping and clamping | forceps, hemostats, needle holders, towel clamps |
| instruments to improve visualization | dilators, probes, retractors, scopes, specula |
| used to stop bleeding | hemostat |
| used to grasp and hold tissue | forceps |
| used to scrape or remove tissue from body cavities | curettes |
| used to make incisions | scalpel |
| used to make the opening of a constricted structure larger | dilator |
| used to pull aside tissue to improve visualization | retractor |
| used to hold sterile towels in place | towel clamps |
| most common solutions used in a procedure | sterile saline and sterile iodine |
| type of surgical drape with a hole in the middle used to expose the surgical area | fenestrated drape |
| reversible loss of consciousness used during major surgery | general anesthesia |
| administered by injection at the site of procedure numbing the point of injection and surrounding tissue | local anesthesia |
| used when a large area of tissue needs to be numb ie:epidural | regional anesthesia |
| numbing agent applied directly to the area of skin that needs to be numb | topical anesthetic |
| most common local anesthetics | lidocaine or xylocaine |
| type of cutting instrument that uses electricity and controls bleeding | cautery or electrocautery |
| holds the edges of a wound together to promote faster healing and reduce scarring | suture |
| type of suture material used internally or in difficult to reach areas, does not need to be removed | absorbable |
| most common suture material used, designed for external structures | nonabsorbable |
| suture sizes range from | 1.0-6.0 |
| smallest suture available is | 6.0 |
| applied to a wound with a stapler | skin staples |
| type of closure indicated for shallow wounds, also helps reinforce sutures | sterile skin closure, steri strips |
| used in place of sutures and staples especially in pediatrics | surgical skin adhesive |
| closing of a wound | laceration repair |
| procedure to remove unwanted tissue like a wart using liquid nitrogen | cryosurgery |
| removal of buildup of sebum which can be complicated by infection | sebaceous cyst removal |
| done on an abscess or localized infection | incision and drainage, I |
| solution that disinfects the skin | isopropyl alcohol |
| common skin prep used during surgery | iodine |
| used to flush and clean open wounds | sterile saline |
| type of soap given to patients to use pre operatively | hibiclens |
| solution that helps enhance adhesive material | tincture of benzoin |
| what part of the instrument will determine the use | the tip |

| device that cleans instruments by transmitting sound waves through a cleaning fluid | ultrasonic cleaner |
| this process helps prevent rust, corrosion and keeps box locks moving freely on surgical instruments | lubricating solution |
| instruments should be inspected for the following | discoloration, defects, and maneuverability |
| the use of a chemical agent to destroy pathogenic organisms | disinfection |
| disinfection is performed on | fomites(inanimate objects) |
| instruments or devices that will penetrate or enter sterile tissue and require sterilization | critical items |
| instruments or devices that may come in contact with non intact skin or mucous membranes | semi critical items |
| examples of semi critical items | scopes: laryngoscopes ;cystoscopies ; sigmoidoscopes |
| instruments that only come in contact with intact skin | non critical items |
| examples of non critical items | blood pressure cuffs; stethoscopes; wheelchairs |
| three levels of disinfecting solutions | low; intermediate, high |
| examples of disinfectants | 10% household bleach; isopropyl alcohol; cidex |
| the complete destruction of all microorganisms including endospores | sterilization |
| sterilization achieved by using steam under pressure | autoclaving |
| autoclaves must reach a temperature of | 250-254 degress F |
| prior to autoclaving instruments should have been | sanitized, inspected, and lubricated |
| materials used to wrap instruments for autoclaving | sterilization paper, sterilization cloth wraps; sterilization pouches |
| devices that help determine whether or not a package has been exposed to high heat and steam and can be considered sterile | sterilization indicators |
| sterilized packs should be labeled with | name of item; date of sterilization, initials of preparer |
