In surgical environments, even minor lapses can have serious consequences. Operating room (OR) cleanliness is essential—not just for aesthetics, but for preventing surgical site infections (SSIs) and protecting patient outcomes. At Ziva Cleaning, we take this responsibility seriously. High standards, rigorous protocols, and meticulous attention to detail in OR cleaning translate directly into surgical safety and success.
According to the Centers for Disease Control and Prevention (CDC), SSIs affect up to 5% of surgical patients, underlining why OR hygiene must adhere to exceptional standards. Environmental and human factors alike demand a multi-layered approach to cleaning and sterilization.
Common Sources of OR Contamination
Even sterile spaces aren’t immune to contamination. The following areas are critical control points.
Airborne Pathogens
Airborne particles carrying bacteria, fungi, and viruses can pose a significant threat. Personnel movement, HVAC systems without HEPA filters, and nearby renovation can all introduce microbial contamination. We follow AORN-recommended air exchange rates and filtration protocols, and maintain positive pressure to prevent airborne microbes from entering the OR. These techniques align with what we’ve outlined in our post, 5 Essential Cleaning Techniques for High-Traffic Medical Clinics.
Instruments & Equipment
Even properly sterilized tools can fail if there's residual bioburden before sterilization. Ziva Cleaning implements strict surface decontamination before sterilization and supports periodic audits to ensure best practices are followed. Our adherence to high-touch sterilization protocols helps reduce the risk of contamination between procedures.
Human Factors
Studies confirm that human traffic increases microbial load in ORs (Whyte et al., 2002). That’s why we limit door openings, enforce strict gowning procedures, and conduct ongoing compliance training to minimize human-sourced contamination. These behaviors help maintain sterility at every stage of the procedure.
Environmental Surfaces
Counters, doorknobs, lighting controls—these are high-touch areas prone to pathogen accumulation. We use hospital-grade disinfectants and follow CDC terminal cleaning checklists, ensuring every surface meets sterilization benchmarks. Our post, What is Terminal Cleaning?, walks through the layered cleaning systems that are critical in surgical environments.
The Three Phases of OR Cleaning
Effective OR cleaning happens in three critical stages:
1. Pre-Operative Cleaning
Disinfect all surfaces—including lighting arms, equipment consoles, ceilings, and floors
Prepare air systems with HEPA filter checks
Stage sterilized instrument trays in controlled zones
These preparations align with our internal protocols and AORN guidelines, guaranteeing surgical readiness.
2. Intra-Operative Maintenance
In longer surgeries, we mop floors, manage spills, and replace soiled drapes—all performed without interfering with the sterile field. This helps maintain surgical sterility throughout the procedure.
3. Terminal/Post-Operative Cleaning
Once surgery ends, we execute terminal cleaning:
Dispose of biohazardous waste, including sharps and linens
Deep-clean and disinfect all horizontal and vertical surfaces
Re-sterilize instruments and ensure proper handling of textiles following AORN’s terminal cleaning standards
For a deeper look at these protocols, read our blog: How Postoperative Cleaning Protocols Prevent Hospital-Acquired Infections.
