Surgical plume – the vapour produced during energy-based procedures – has long been overlooked as a potentially dangerous by-product of modern surgery. Plume reduction devices have emerged as vital tools in maintaining operating room and treatment room safety. These devices are engineered to control and remove airborne contaminants generated by lasers, electrosurgery units, and other heat-producing instruments.
As surgical technologies advance, so too does our awareness of occupational and patient safety.
Plume reduction represents a convergence of infection control, air quality management, and surgical innovation. It complements enhanced filtration systems, robotic surgical tools, and real-time monitoring devices – all aimed at safer, more efficient procedures.

Understanding Plume Reduction Devices
Plume reduction devices are mechanical filtration systems designed to capture and filter surgical smoke and vapours generated during procedures. Their purpose is to protect surgical staff and patients from inhaling potentially hazardous airborne particles.
These devices operate by:
- Suctioning plume from the surgical field via a vacuum hose.
- Passing it through a multi-stage filtration system (typically including HEPA or ULPA filters and activated carbon).
- Releasing filtered air back into the environment or directed to external exhaust systems.
They are often built into surgical energy devices or used as standalone evacuation units that integrate with operating theatre ventilation.
Applications of Plume Reduction Devices in Medical Practice
âś“Â Surgical Use
Plume reduction devices are essential in procedures using:
- Electrosurgery
- Laser surgery
- Radiofrequency ablation
- COâ‚‚ laser dermatological treatments
- Laparoscopic and robotic surgeries (especially where insufflation is involved)
âś“Â Non-Surgical Use
They are also used in:
- Cosmetic and dermatological treatments (laser hair removal, tattoo removal)
- Outpatient procedures in dermatology, podiatry, and gynaecology
âś“Â Use-Case Examples
- Laser resurfacing: Effective plume control ensures visibility for precision treatment and reduces staff exposure to viral particles.
- Wart removal with electrocautery: Prevents inhalation of potentially infectious smoke plumes, such as HPV particles.
- Laparoscopic hysterectomy: Utilising a filtered insufflation system reduces intraperitoneal smoke build-up.
Advantages and Limitations of Plume Reduction
Key Benefits
For clinicians and patients, plume reduction devices offer:
- Improved air quality in theatres
- Reduced occupational exposure to harmful particles and toxic chemicals
- Protection from bioaerosols, including bacteria and viruses
- Enhanced surgical field visibility, leading to improved precision
Limitations and Considerations
- Cost and maintenance: Systems require ongoing filter replacements and servicing.
- Noise levels: High-suction systems may introduce auditory distraction.
- User training: Effective use requires staff to understand proper placement and maintenance protocols.
- Compliance: Institutions must ensure systems meet regulatory standards, such as TGA-approved filtration levels.

Plume evacuators are the only option capable of removing biological particulates directly at the point of origin, making them essential for procedures involving tissue vaporisation.
Latest Innovations in Plume Reduction
Emerging developments in plume control include:
- Smart evacuation systems: Integrated with surgical devices, adjusting suction based on device use.
- Wireless foot controls for better ergonomics.
- Wearable air monitors for real-time assessment of airborne contaminant exposure.
- Built-in filtration in robotic arms, especially in minimally invasive surgeries.
Research is also exploring the viability of inactivating viral particles within evacuation filters, particularly in the context of SARS-CoV-2 and HPV.
Kleer Aid Laser Patch for Laser Hair Removal
At the 2024 Hot Topics Session at ASPS USA Plastic Surgery The Meeting, Plastic Surgeon Barry DiBernardo spoke about Plume Research for Laser Hair Removal and the Kleer Aid Laser Patch.
Use of the patch resulted in 99% Plume Reduction, 33% decreased pain, 7% better hair clearance and reduced buildup on the lens.
Education and Ethical Considerations
âś“Â Informed Consent
While surgical plume is primarily a workplace safety issue, patients benefit from understanding:
- The presence and nature of surgical smoke
- That plume control measures are in place to support a safe surgical environment
âś“Â Clinician Responsibility
Healthcare providers play a vital role in:
- Educating staff on plume management protocols
- Explaining to patients what to expect
- Ensuring ethical communication about surgical environments
In Summary
Plume reduction devices are an indispensable part of today’s surgical safety infrastructure. By capturing airborne contaminants at their source, they protect both clinicians and patients while supporting high-quality surgical outcomes.
Understanding the role, functionality, and limitations of these systems helps practitioners make informed choices and ensures that patient care remains at the heart of innovation. As technologies evolve, plume control will continue to improve – but ethical, transparent communication will always remain essential.
