Spaulding Classification

CST SURGICAL TECH

Definition

Processing framework: critical (sterilize), semi-critical (high-level disinfect), non-critical (low-level disinfect).

Calculation Methods

Relevant parameters for spaulding classification in the surgical setting:

Cidex OPA: High-level disinfection (not sterilization). 0.55% OPA, 12 minutes soak at 20 C. For semi-critical items (endoscopes). Rinse thoroughly
Sterrad (H2O2 plasma): Low-temperature hydrogen peroxide gas plasma. 104-131 F, 28-75 min cycle. For heat-sensitive electronics, scopes. No cellulose/linen

Professional Standards

Professional standards for spaulding classification include adherence to AST (Association of Surgical Technologists) guidelines:

ETO (ethylene oxide): Chemical gas sterilization. Parameters: 600mg/L concentration, 130 F, 2-5 hours exposure, 8-12 hours aeration. For heat/moisture-sensitive items
Sterrad (H2O2 plasma): Low-temperature hydrogen peroxide gas plasma. Parameters: 104-131 F, 28-75 min cycle. For heat-sensitive electronics, scopes. No cellulose/linen

Workplace Applications

In daily practice, spaulding classification is applied consistently according to facility protocols and current evidence-based guidelines. Competency is maintained through annual skills validation, continuing education, and quality improvement participation.

Documentation

Surgical documentation for spaulding classification includes: operative consent verification, time-out confirmation (correct patient, correct site, correct procedure), specimen labeling and pathology requisition, instrument and sponge count results, and any implant records with lot numbers and serial numbers. All counts must be documented as correct or incorrect with follow-up actions.

Why It Matters

Frequently Asked Questions

What instruments are used for spaulding classification?▼

For spaulding classification: Metzenbaum scissors (Cutting/dissecting): Delicate tissue dissection, curved blades for undermining. Balfour retractor (Retraction): Self-retaining abdominal retractor with lateral and bladder blades. Needle holder (Suturing): Holds suture needles, tungsten carbide inserts for grip, box lock mechanism.

What sterile technique rules apply to spaulding classification?▼

For spaulding classification: Edges of anything that encloses sterile contents are considered unsterile (1-inch border). If the sterility of an item is in doubt, consider it contaminated. Sterile drapes are placed from the operative site outward (near to far).

What sterilization method is used for equipment related to spaulding classification?▼

For spaulding classification: Cidex OPA: High-level disinfection (not sterilization). Parameters: 0.55% OPA, 12 minutes soak at 20 C. For semi-critical items (endoscopes). Rinse thoroughly.
