Suture Materials

CST SURGICAL TECH

Definition

Classification by absorbability, structure, material, and USP size system.

Regulatory Context

Regulatory context for suture materials includes federal and state requirements. Healthcare facilities must comply with CMS Conditions of Participation, state licensure requirements, and accreditation standards (Joint Commission or AAAHC). Non-compliance can result in citations, fines, or loss of Medicare/Medicaid reimbursement.

Exam Focus Areas

On the Cst Surgical Tech exam(s), questions about suture materials typically test:

  1. Instrument identification, function, and proper passing technique
  2. Sterile technique maintenance and contamination recognition
  3. Sterilization parameters and monitoring methods

Step-by-Step Procedure

Procedural steps relevant to suture materials in the surgical setting:

  1. Initial count performed before incision: sponges, sharps, instruments, miscellaneous
  2. Closing counts: first closing count (deep layers), second closing count (skin closure)
  3. All counts are audible, visual, and concurrent (scrub tech and circulator together)
  4. Sponges counted in groups of 5, radiopaque sponges only used on the field
  5. Incorrect count protocol: notify surgeon then recount then wound search then X-ray if unresolved
  6. Sharps counted on a needle counter/magnet, broken needles: account for all pieces
  7. Add-on items must be counted when added and at subsequent count times

Assessment Techniques

Classification by absorbability, structure, material, and USP size system. Suture properties tested on CST exam.

Related instrumentation: Balfour retractor (Retraction) for Self-retaining abdominal retractor with lateral and bladder blades.

Workplace Applications

In daily practice, suture materials 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.

Why It Matters

Frequently Asked Questions

What sterilization method is used for equipment related to suture materials?
For suture materials: Steam (autoclave): Saturated steam under pressure. Parameters: Gravity: 250 F (121 C) x 30 min. Prevacuum: 270 F (132 C) x 4 min. Flash: 270 F x 3 min (unwrapped).
What is the counting procedure for suture materials?
For suture materials: Initial count performed before incision: sponges, sharps, instruments, miscellaneous. Closing counts: first closing count (deep layers), second closing count (skin closure). Sponges counted in groups of 5, radiopaque sponges only used on the field.
What sterile technique rules apply to suture materials?
For suture materials: Movement around the sterile field must not cause air currents, no reaching over the field, no turning back to the field. Edges of anything that encloses sterile contents are considered unsterile (1-inch border). Sterile field is created as close to the time of use as possible and never left unattended.
