Investing in surgical instruments is a substantial commitment for any hospital, emphasizing the vital role played by their proper care and maintenance in both surgical procedures and patient well-being.
Within the hospital infrastructure, the Sterile Processing Department, also known as Central Supply or Sterile Processing Service, takes charge of cleaning, preparing, processing, storing, and issuing medical/surgical supplies and equipment, whether sterile or non-sterile.
The Sterile Processing Departments typically encompass four main areas to fulfill their functions: decontamination, assembly and sterile processing, sterile storage, and distribution. In the decontamination area, reusable equipment undergoes cleaning and decontamination through manual or mechanical processes and chemical disinfection. Following this crucial step, a meticulous microscopic inspection of the instruments becomes paramount.
Visual Inspection for Quality Control
Post-cleaning, all instruments must undergo a thorough inspection before being packaged for reuse or storage. The significance of inspecting each instrument cannot be overstated. A visual assessment for cleanliness and dryness is imperative for all items after the decontamination process.
The condition of an instrument significantly influences its cleaning efficacy. Instruments subjected to rough handling may develop scratches and rough surfaces over time, providing hiding places for dirt. Damaged surfaces not only become havens for dirt and bacteria but also pose potential risks to both medical staff and patients.
Critical areas such as box locks, serrations, and crevices demand meticulous inspection for cleanliness. Instruments with cutting edges, including scissors, rongeurs, chisels, and curettes, should undergo checks for sharpness, ensuring the absence of dull spots, chips, or dents. Hinged instruments like clamps and forceps require scrutiny for stiffness, alignment of jaws, and teeth. Properly aligned tips, perfectly meeting jaws, and easily movable joints are prerequisites.
Ratchets should close seamlessly and hold firmly, and instruments featuring pins or screws must be inspected for integrity. Plated instruments need examination to ensure no chips, worn spots, or sharp edges are present. Worn spots can rust during autoclaving, and chipped plating can trap dirt, potentially causing harm to tissue and rubber gloves if not adequately cleaned.
Any identified issues during the inspection process necessitate either a thorough cleaning or, depending on the observed problem, referral for repair.
Utilizing Advanced Visualization Tools
While various visualization tools are available for instrument inspection, stereo inspection microscopes stand out by providing technicians with a 3D view of instruments, enabling them to assess all sides simultaneously. This approach is particularly beneficial for visualizing challenging areas like box locks and jaws, known to harbor residual bioburden effectively.
General Guidelines for Instrument Inspection
Forceps and Hemostats: A visual test involves lightly closing the jaws. If they overlap, realignment is needed. Serrated jaws should mesh fully, and there should be no play in the box joint.
Scissors: Blades require scrutiny for burrs and should maintain good approximation throughout their length. Excessive fretting around the pivot pin, indicating possible corrosion and breakage, should be avoided.
Needle Holders: Clamping a needle in the jaw and closing the instrument should ensure the needle remains secure without easy movement or turning.
