Sterilization and Handling of Instruments
Maintaining sterility of surgical instruments is paramount to prevent surgical site infections and ensure patient safety; Surgical technologists are responsible for adhering to strict protocols for cleaning, decontamination, and sterilization of all instruments used in the operating room. The process begins immediately after a surgical procedure with point-of-use cleaning, which involves removing gross debris from the instruments using enzymatic detergents and water.
Following point-of-use cleaning, instruments are transported to the central sterile supply department (CSSD) for further processing. Here, instruments undergo a thorough cleaning and decontamination process using automated washers and ultrasonic cleaners. These machines remove organic material and reduce the bioburden on the instruments.
After cleaning, instruments are inspected for damage and proper function. Those that pass inspection are then assembled into sets and packaged for sterilization. Common sterilization methods include steam sterilization (autoclaving), which uses high-pressure steam to kill microorganisms, and chemical sterilization, which utilizes sterilizing agents like ethylene oxide or hydrogen peroxide gas plasma. The choice of sterilization method depends on the type of instrument and its compatibility with the sterilizing agent.
Proper handling of sterile instruments is crucial to maintain their sterility. Surgical technologists must use aseptic techniques when handling instruments, including wearing sterile gloves and gowns and using sterile transfer methods. Instruments should be stored in a designated sterile area and protected from contamination. Any instrument that becomes contaminated must be removed from the sterile field immediately.
Instrument Identification and Terminology
A foundational skill for surgical technologists is the ability to quickly and accurately identify surgical instruments by name and function. This knowledge is critical for anticipating the surgeon’s needs and ensuring a smooth and efficient surgical procedure. Mastery of instrument terminology enhances communication within the surgical team and minimizes the risk of errors.
Surgical instruments are broadly classified based on their primary function, such as cutting, grasping, clamping, retracting, or suturing. Within each category, there are numerous variations of instruments, each designed for specific tasks or tissue types. For example, within the cutting category, scalpels are used for making incisions, while scissors are used for dissecting tissue.
Many instruments are named after the surgeons who originally designed or popularized them, such as the Kocher clamp or the DeBakey forceps. Understanding the etymology of instrument names can aid in memorization and comprehension of their intended use. Instrument names often reflect their shape, size, or specific features. For example, curved hemostats are used to clamp blood vessels, while right-angle clamps are designed for accessing hard-to-reach areas.
