• Return electrodes
• Procedure-specific accessories

Proper operation requires trained personnel and adherence to equipment instructions and clinical safety protocols.

10. Surgical Suction Equipment

Suction systems help remove unwanted fluids or materials from the operative field.

A typical system can include:

Suction Source → Tubing → Collection Container → Suction Instrument

Applications can include removal of:

• Blood
• Irrigation fluids
• Secretions
• Other fluids encountered during procedures

11. Surgical Consumables

Consumables are supplies used during procedures that may be discarded after use or processed according to their intended design.

Examples include:

• Surgical gloves
• Masks
• Sterile gowns
• Drapes
• Gauze
• Surgical sponges
• Sutures
• Needles
• Syringes

• Vacuum
• Other gases required for specific clinical applications

Gas systems require appropriate installation, monitoring and safety procedures.

20. Sterilization and Instrument Processing

Reusable surgical instruments require appropriate cleaning and sterilization before reuse.

A simplified workflow is:

Collection → Cleaning → Inspection → Packaging → Sterilization → Storage → Distribution

The CDC identifies cleaning as an essential step before sterilization and recommends appropriate sterilization methods based on the type of instrument and its resistance to heat, moisture and other conditions.

21. Cleaning Before Sterilization

Sterilization is not a substitute for cleaning.

Organic and inorganic material should be appropriately removed before sterilization because contamination can interfere with effective processing.

The CDC's infection-control guidance emphasises cleaning as an essential component of successful disinfection and sterilization.

22. Steam Sterilization

Steam sterilization is commonly used for critical instruments that can tolerate heat, pressure and moisture.

The CDC describes steam as the preferred method for sterilizing heat- and moisture-stable critical medical and surgical instruments.

Heat- or moisture-sensitive devices may require other validated sterilization technologies.

23. Reusable vs Single-Use Items

Operating rooms use both reusable and single-use products.

Reusable Items

Examples can include:

• Many stainless-steel instruments
• Retractors
• Clamps
• Certain surgical equipment

These require validated reprocessing.

Single-Use Items
