Surgical Skin Preparation

CST SURGICAL TECH

Definition

Antiseptic preparation of surgical site to reduce microbial count and SSI risk.

Equipment & Tools

Instruments and tools relevant to surgical skin preparation:

InstrumentCategoryUse
Bovie (ESU)ElectrosurgeryCut (continuous waveform) and coag (interrupted waveform) modes for hemostasis
Metzenbaum scissorsCutting/dissectingDelicate tissue dissection, curved blades for undermining
Needle holderSuturingHolds suture needles, tungsten carbide inserts for grip, box lock mechanism
Kelly clampClampingHemostasis on medium vessels, half-serrated jaws

Step-by-Step Procedure

Procedural steps relevant to surgical skin preparation 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

Common Errors

Surgical technology errors related to surgical skin preparation include:

Safety Considerations

Maintaining safety during procedures involving surgical skin preparation requires adherence to sterile technique:

Patient Communication

Clear communication about surgical skin preparation with patients, families, and the healthcare team is essential. Use standardized handoff tools (SBAR) for shift changes and transfers. Verify understanding by asking the patient to repeat key information back to you.

Practical Example

In the OR: During a procedure involving surgical skin preparation, the surgical technologist may handle:

  • Richardson retractor (Retraction): Deep abdominal retraction, handheld, curved blade
  • Allis clamp (Grasping): Grasping tissue without crushing (bowel, fascia), traumatic teeth
  • Kocher clamp (Clamping): Grasping heavy tissue (fascia), has teeth, NOT for vessels

Why It Matters

Technique, agent selection, and fire safety tested on CST exam.

Frequently Asked Questions

What instruments are used for surgical skin preparation?
For surgical skin preparation: Bovie (ESU) (Electrosurgery): Cut (continuous waveform) and coag (interrupted waveform) modes for hemostasis. Senn retractor (Retraction): Superficial retraction, double-ended: sharp prongs and flat blade. Deaver retractor (Retraction): Deep retraction in abdominal/pelvic surgery, C-shaped blade.
What sterilization method is used for equipment related to surgical skin preparation?
For surgical skin preparation: 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.
What sterile technique rules apply to surgical skin preparation?
For surgical skin preparation: Moisture strikes through: wet drapes are contaminated, use impervious drapes and keep the field dry. 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.
