Why is surgical smoke becoming a legislative issue in the United States?
Surgical smoke has long been a familiar byproduct of electrosurgery in the operating room. But in the United States, the way it is being addressed is changing.
By 2025, 20 U.S. states had enacted laws addressing surgical smoke evacuation. In 2026, legislation concerning surgical smoke evacuation was under consideration in 11 additional states: Florida, Hawaii, Iowa, Kansas, Maryland, Massachusetts, Michigan, Oklahoma, Pennsylvania, South Carolina, and Wisconsin. [1,2]
That raises a more fundamental question:
What has changed to turn surgical smoke from a routine operating-room issue into a legislative and occupational-safety concern?
The answer is not a single study or a recent regulatory decision.
It is the result of years of research gradually changing the question from:
“Is surgical smoke harmful?”
to:
“How effectively can it be controlled under real surgical conditions?”
From Recognizing the Problem to Measuring the Exposure
Research has increasingly moved beyond simply identifying the substances present in surgical smoke.
A randomized controlled trial conducted at The University of Tokyo Hospital evaluated whether a dedicated smoke evacuator could reduce exposure during laparotomy. Among 42 patients, the use of a smoke evacuator significantly reduced acetaldehyde and formaldehyde levels, while particle counts were reduced by approximately 80–95% across the particle sizes evaluated. [3]
This provided clinical evidence that smoke evacuation can reduce measurable exposure.
But it also led to a more specific engineering question:
Does it matter where the smoke is captured?
Where Smoke Is Captured Matters
A subsequent randomized, double-blind clinical trial at The University of Tokyo Hospital examined different smoke evacuation configurations in 64 patients undergoing laparotomy.
The study compared electrocautery-incorporated smoke evacuation at an 8 mm or 18 mm tip distance with conventional hose-type evacuation.
Under the study conditions, the 8 mm configuration reduced particle counts by approximately 96–97% across particle sizes from 0.3 to 5.0 μm compared with hose-type evacuation. Acetaldehyde and formaldehyde levels were also significantly lower. [4]
The finding is important because it shifts the discussion away from a simple question of whether suction is present.
The location and method of capture can influence the amount of smoke that reaches the surrounding operating environment.
In other words, smoke evacuation is not only a question of how much air a system can move.
It is also a question of where that air is being drawn from.
Surgical Smoke Is Dynamic
More recent research has added another dimension to the problem: time.
A 2026 study published in the Journal of Surgical Research evaluated 60 laparoscopic cholecystectomy procedures using real-time measurements of PM1, PM2.5, PM10, and total particulate matter.
When the researchers compared only the overall average particulate concentrations, continuous vacuum-assisted evacuation showed only a nonsignificant trend toward lower values.
However, when the temporal variation of particulate exposure was analyzed, continuous evacuation was associated with significant reductions across all measured particle sizes. The reductions were also greater in more complex procedures. [5]
This finding highlights an important characteristic of surgical smoke:
It is not a static exposure.
Smoke generation changes with the use of electrosurgical energy, tissue characteristics, surgical technique, instrument movement, and the stage of the procedure.
Therefore, evaluating smoke evacuation through a single parameter or a single overall average may not fully describe how a system performs throughout an actual operation.
So, Is Suction Power the Real Question?
This is where the discussion becomes particularly interesting.
A smoke evacuation system is, fundamentally, a suction system. Flow rate and negative pressure are measurable engineering parameters. It is therefore natural to assume that stronger suction should mean better smoke evacuation.
But the evidence above points to a broader question.
Consider the complete pathway:
Smoke Generation → Source Capture → Transport → Filtration → Exhaust
Suction is involved throughout this pathway, but suction power alone does not describe the performance of the entire system.
If smoke is captured close to its source, less smoke has the opportunity to disperse into the surrounding environment.
If the transport pathway introduces excessive resistance or leakage, performance at the capture point may not translate into effective removal.
If filtration is inadequate, removing air does not necessarily mean adequately controlling the contaminants carried in that air.
And if a system is difficult to integrate into the surgical workflow, theoretical performance may not translate into consistent use.
This leads to a different way of thinking about smoke evacuation:
The question is not simply, “How powerful is the suction?”
It is:
“How effectively does the system capture and remove surgical smoke where and when it is generated?”
From Legislative Momentum to a System-Level Question
The growing number of state laws does not, by itself, define what constitutes the best smoke evacuation technology.
But it does signal a broader change in expectations.
Surgical smoke is increasingly being addressed as an exposure that should be controlled, rather than simply accepted as an unavoidable consequence of electrosurgery. [1,2]
At the same time, research is moving toward increasingly detailed questions about capture location, exposure dynamics, particulate behavior, and real-world evacuation performance. [3–5]
The regulatory question and the engineering question are therefore beginning to converge.
Once smoke must be controlled, the next question is:
What does effective control actually mean?
TAKTVOLL Insight
At TAKVOLL, we view electrosurgical energy delivery and smoke management as connected parts of the same clinical workflow.
Energy is delivered to tissue.
Smoke is generated.
That smoke must then be captured, transported, filtered, and removed from the operating environment.
From this perspective, smoke management cannot be reduced to a single suction specification.
Capture distance, airflow, transport efficiency, filtration, system integration, and the interaction between the energy device and the evacuation system all contribute to the final result.
This is why we believe the next step in surgical smoke evacuation is not simply more suction power.
It is better system-level control.
As clinical evidence continues to evolve and smoke evacuation becomes increasingly embedded in workplace-safety requirements, the industry may need to look beyond isolated specifications and toward how the entire smoke-management pathway performs in real surgery.
The future of surgical smoke evacuation is not simply about how much a system can suction.
It is about how effectively it manages smoke at the point, time, and conditions where it is generated.
