Sterile Technique and Aseptic Practice
Explain your process for maintaining the sterile field during surgery.
Rigorous protocol prevents contamination. Pre-operative preparation includes surgical scrub using antimicrobial soap scrubbing hands and arms for the recommended duration per facility protocol with attention to nails, gowning and gloving donning sterile gown and gloves using proper technique maintaining hands above waist, and establishing sterile field arranging drapes and instruments without contamination. Sterile boundaries define the outer edge of drapes as non-sterile, the front of the gown from waist to shoulder level as the sterile zone (with hands kept in sight), and the back as non-sterile (never turning it toward the field).
Continuous monitoring watches for breaches observing all team members’ movements, addresses contamination immediately replacing contaminated items without hesitation, and maintains awareness tracking who and what enters sterile field. Common contamination risks include reaching over sterile field from non-sterile position, splashing from non-sterile surfaces onto field, and hair or jewelry touching sterile areas. Traffic control limits personnel in OR reducing unnecessary movement, restricts talking near field minimizing airborne particles, and closes doors maintaining positive pressure ventilation. Documentation importance records any breaches in OR log for quality assurance, reports to charge nurse for review, and participates in debriefing discussing improvements preventing future occurrences demonstrating professional accountability for patient safety.
How do you handle a sterile field breach during a procedure?
Immediate action protects patients. Recognition identifies breach immediately noticing unsterile item touching field, questioning doubtful situations using “when in doubt, throw it out” principle, and trusting instincts not ignoring concerns even under pressure. Communication announces breach clearly stating “contamination” to alert team, specifies location pointing to affected area, and maintains calm avoiding panic that disrupts procedure. Remediation removes contaminated items replacing with sterile equivalents, re-drapes if necessary covering compromised area, and rescrubs/regloves for personnel who broke sterile technique.
Team response shows circulator retrieves replacement items opening packages using sterile technique, surgeon pauses if needed waiting for field restoration, and documentation records incident for quality review. Prevention strategies include pre-procedure timeout confirming everyone understands sterile boundaries, environmental control maintaining appropriate temperature and humidity, and fatigue management taking breaks during long cases reducing errors from exhaustion. Learning culture participates in debriefing discussing what happened and why without blame, suggests improvements proposing system changes preventing recurrence, and shares lessons teaching others from experiences creating safer environment for all patients demonstrating mature professional commitment to continuous improvement.

Basic categories include cutting instruments like scalpels with common blade options appropriate to the case and scissors (Mayo for heavy tissue, Metzenbaum for delicate dissection), grasping instruments including forceps (Adson with teeth for skin, DeBakey for vascular tissue) and clamps (hemostats, Kelly clamps, Kocher for heavy tissue), and retraction instruments such as Army-Navy retractors for superficial work and self-retaining Bookwalter or Balfour for deep cavities. Specialty instruments vary by procedure like orthopedic using drills, saws, and plates, cardiovascular requiring vascular clamps and cannulas, and laparoscopic needing trocars, insufflators, and specialized long instruments.
Anticipation skills predict needs passing instruments before requested by following procedure flow, observe surgeon preference noting individual technique variations, and maintain rhythm establishing smooth handoff patterns. Handling technique includes passing safely placing handle in surgeon’s palm without slapping, orienting correctly positioning instrument ready to use, and protecting points keeping sharp instruments visible and controlled. Troubleshooting addresses malfunctions checking instrument function before surgery, recognizes damage spotting broken tips or loose joints, and requests replacements quickly communicating needs to circulator ensuring uninterrupted procedure flow demonstrating technical proficiency essential for surgical tech competency.
Q: Walk through instrument sterilization procedures.
Multi-step process ensures safety. Decontamination phase includes pre-cleaning rinsing instruments immediately after use preventing blood and tissue from drying, transporting safely using closed containers to decontamination area, and personal protective equipment wearing utility gloves, mask, and eye protection during cleaning. Manual cleaning uses enzymatic detergent breaking down protein and organic matter, brushing thoroughly cleaning serrations, box locks, and crevices, and ultrasonic cleaner using sound waves reaching difficult areas removing debris effectively.
Sterilization methods employ steam autoclave most common method using pressurized steam on a validated cycle per the instrument IFU and facility policy, ethylene oxide gas for heat-sensitive items like plastics and electronics with an extended aeration/processing cycle, and hydrogen peroxide plasma low-temperature alternative for delicate instruments. Quality assurance includes biological indicators using routine biological indicator (spore) testing verifying sterilization effectiveness, chemical indicators changing color confirming exposure to sterilization conditions, and mechanical monitors checking cycle parameters and printouts/indicators. Documentation maintains load records tracking each sterilization cycle, instrument tracking logging individual instruments through process, and recall procedures enabling retrieval if sterilization failure detected ensuring patient safety through rigorous processing standards demonstrating professional responsibility for infection prevention.
Surgical Counts and Documentation
Q: Explain the surgical count procedure.
Critical safety protocol prevents retained foreign objects. Count timing includes initial count before procedure begins counting all items on sterile field with circulating nurse, closing count before closing any cavity or deep layer, and final count before skin closure ensuring everything accounted for. Items counted encompass sharps including needles, scalpel blades, and any sharp instruments, soft goods such as sponges, towels, and lap pads, and instruments all items in set including added instruments during procedure.
Count procedure methodology performs aloud both scrub tech and circulator calling out numbers simultaneously, counts twice confirming initial count before opening additional packages, and documents immediately recording on count sheet preventing memory errors. Discrepancy management initiates search thoroughly checking trash, floor, drapes, and Mayo stand, notifies surgeon halting closure until located, and obtains x-ray if not found before closing with radiograph confirming absence from patient. High-risk scenarios include emergency surgery when counts may be abbreviated documenting deviation, patient instability when count performed as situation allows prioritizing life-threatening issues, and obese patients where items more easily lost in folds requiring extra diligence. Documentation requirements include count sheet signed by both scrub and circulator verifying accuracy, incident report for incorrect counts describing circumstances and resolution, and permanent record attaching to patient chart creating legal documentation showing adherence to safety protocols.
OR Setup and Case Preparation
Q: How do you prepare an operating room for surgery?
Systematic approach ensures readiness. Pre-case review checks surgery schedule confirming procedure details, surgeon preferences noting specific equipment or instrument requests, and patient information reviewing allergies, medical history, and positioning requirements. Room setup includes furniture arrangement positioning OR table, Mayo stand, back table, and equipment appropriately, equipment check testing suction, electrocautery, lights, and specialty equipment, and supplies gathering ensuring adequate quantities of sutures, sponges, and other consumables.
Instrument preparation opens sets maintaining sterility using proper opening technique, arranges instruments organizing logically by procedure phase, and adds specialty items including procedure-specific instruments or implants. Draping preparation prepares patient drapes organizing in order of use, sets up Mayo stand covering with sterile drape and arranging instruments, and establishes back table for additional instruments and supplies. Final verification conducts timeout confirming patient identity, procedure, site, and allergies before incision, reviews count completing initial count with circulator, and confirms readiness communicating with team that all preparations complete ensuring coordinated start.
Q: Describe handling equipment malfunctions during surgery.
Quick response maintains safety. Immediate assessment determines severity evaluating if alternative exists or procedure must pause, identifies problem checking obvious issues like unplugged cords or empty tanks, and communicates clearly alerting surgeon and circulator to situation. Troubleshooting basics includes checking connections ensuring cables plugged in securely, replacing disposables swapping out defective handpieces or tips, and testing backup using redundant equipment if available.
✓ Best practice: Always test critical equipment before procedure begins – run suction, test cautery, check light functionality. Prevention better than crisis management mid-surgery.
Escalation procedure requests biomedical engineering calling for technical support, documents malfunction recording for equipment tracking and maintenance, and considers alternatives suggesting different approach if equipment unavailable. Common malfunctions include electrocautery failure often from poor grounding or dead battery, suction issues frequently from clogs or loose connections, and light problems typically requiring bulb replacement. Prevention strategies involve pre-procedure testing verifying all equipment functional, regular maintenance following manufacturer service schedules, and backup planning identifying alternatives before starting preventing delays when malfunctions occur demonstrating proactive approach to patient safety and surgical efficiency.
