Laser Safety in Surgery

CST SURGICAL TECH

Definition

Operating room laser precautions: eye protection, fire prevention, smoke evacuation, and controlled access per ANSI standards.

Exam Focus Areas

On the Cst Surgical Tech exam(s), questions about laser safety in surgery typically test:

Counting procedures and protocols for discrepancies
Sterile technique maintenance and contamination recognition
Sterilization parameters and monitoring methods

Overview

Operating room laser precautions: eye protection, fire prevention, smoke evacuation, and controlled access per ANSI standards. Laser safety requirements tested on CST exam.

Related instrumentation: Mayo scissors (Cutting) for Heavy tissue and suture cutting, straight (suture) or curved (tissue).

Calculation Methods

Relevant parameters for laser safety in surgery in the surgical setting:

Steam (autoclave): Saturated steam under pressure. Gravity: 250 F (121 C) x 30 min. Prevacuum: 270 F (132 C) x 4 min. Flash: 270 F x 3 min (unwrapped)
Cidex OPA: High-level disinfection (not sterilization). 0.55% OPA, 12 minutes soak at 20 C. For semi-critical items (endoscopes). Rinse thoroughly

Key Values & Ranges

Operating room laser precautions: eye protection, fire prevention, smoke evacuation, and controlled access per ANSI standards. Laser safety requirements tested on CST exam.

Related instrumentation: Mosquito clamp (Clamping) for Hemostasis on small vessels, fully serrated, delicate.

Frequently Asked Questions

What sterile technique rules apply to laser safety in surgery?▼

For laser safety in surgery: Moisture strikes through: wet drapes are contaminated, use impervious drapes and keep the field dry. Movement around the sterile field must not cause air currents, no reaching over the field, no turning back to the field. Gowns are considered sterile from chest to waist level, sleeves from 2 inches above the elbow to the cuff.

What is the counting procedure for laser safety in surgery?▼

For laser safety in surgery: Sharps counted on a needle counter/magnet, broken needles: account for all pieces. Incorrect count protocol: notify surgeon then recount then wound search then X-ray if unresolved. Sponges counted in groups of 5, radiopaque sponges only used on the field.

What instruments are used for laser safety in surgery?▼

For laser safety in surgery: Kelly clamp (Clamping): Hemostasis on medium vessels, half-serrated jaws. Balfour retractor (Retraction): Self-retaining abdominal retractor with lateral and bladder blades. Deaver retractor (Retraction): Deep retraction in abdominal/pelvic surgery, C-shaped blade.
