Prioritizing Surgical Plume

Evacuation of Surgical Plume needs to be a Priority in All Surgical Facilities

Managers in U.S. operating rooms must comply with mandates such as those imposed by OSHA through the Blood Bourne Pathogen Rule¹. The cost of such regulation is reflected in the purchases of fluid management devices, safety scalpels and syringes, face shields, other related consumables and nursing time needed to implement the requirements.

Certainly, managers must prioritize these mandates…but should they do so while disregarding related rules issued by OSHA², guidelines of JCAHO³, a NIOSH safety alert⁴ and the best practices recommendations of AORN⁵? All of these entities, as well as others ^{6 7 8 9 10}, advocate for evacuation of surgical plume from the operating room because of the potentially infectious elements¹¹ and mutagenic/carcinogenic chemicals identified as present in the plume¹². It needs to be remembered that smoke is composed of vapor (liquid) and particulates released when cells are ruptured by the heated instruments used for incision and coagulation of human tissue. That body fluid (intra‐ and intercellular water as well as blood) contains the same potential pathogens found in blood^{13 14} and other fluids who’s management has been carefully regulated by OSHA’s Blood Bourne Pathogen Rule. What this mandate implies is that healthcare workers need to be protected from pathogens found in blood, ascites and saline irrigation but not protected from fluids from the same body that are also present in surgical smoke which also contains carcinogenic chemicals not found in the other bodily fluids.

While the threat of splash‐back of bodily fluids onto the mucus membranes of nurses is minimal with current precautions, the threat to the worker from inhaled surgical plume is definite and continuous because surgical masks offer little if any protection to the worker from inhalation of contaminated smoke¹⁵.

It is not surprising, therefore, that reports of HPV (human papilloma virus) infection in the respiratory tract of doctors involved in the fulguration of venereal warts have been reported^{16 17}. Nor is it surprising to note that the incidence of respiratory illnesses in perioperative nurses is twice that found in the general U.S. population¹⁸.

Studies indicate that poor air quality results in increased absenteeism and decreased productivity. Alternatively, efforts to improve air quality can decrease absenteeism by as much as 60%¹⁹ and productivity by 17%²⁰. In a 2010 report, absenteeism in Canadian nurses which was due to illness, often respiratory (25%), was as high as 9% among public sector nurses. This resulted in an overtime rate of 17.3% at a total annual cost of $660,300,000²¹.

Perhaps a fractional decrease will be found in the operating room when surgical plume, bone dust, chemical vapors from glues and other air contaminants are removed through effective smoke capture resulting in enormous savings in manpower costs for the surgical facility. Devices capable of achieving such capture in O.R.’s have not yet been available so that no comparable studies regarding absenteeism have yet been reported although such a device with such a capability has been described²².

Certainly, the entire principle of laminar air flow dictates that infection rates are decreased by performing surgery in a clean air environment²³. Consider the “sick building syndrome”²⁴, the deaths caused by primary²⁵ and secondary²⁶ cigarette smoke inhalation and studies linking inhalation of asbestos to mesothelioma²⁷ decades after the exposure and COPD caused by, “…exposure to air pollutants in the ambient air and workplace environment…”²⁸ for one to appreciate both the benefits and the liabilities of clean air or the lack thereof.

The risk of litigation to hospitals by their employees based upon a disregard by the administration of the tenets of the Clean Air Act and the General Duty Clause of the OSHA Act must be considered by the Compliance Officer of the healthcare facility who’s concern it is to limit such liability. These federal regulations require that the employer (hospital) provide a safe working environment for their employees which includes non‐contaminated air to breathe. Clearly, a smoke‐filled operating room which harbors irritants and potential pathogens does not qualify as a “safe working environment.” Litigation related to the absence of clean air has already been ruled on by the courts in the plaintiff’s favor^{29 30}. Minimizing such exposure is critical and possible to achieve if such a solution is currently available and hospitals fail to act on such information.

While one can readily see the need to provide unadulterated air for the O.R. team to breathe during their working hours, how can it be done in a practical way? Past and current attempts have involved trying to have a team member corral smoke, which is hot and wants to rise quickly and disperse widely, toward a 3/8” I.D. or a 7/8” I.D. tube which is connected to a suction source. Unfortunately, these devices can be tiring to hold, interfere with the surgeon’s vision, require team involvement and most significantly, are often less than effective. Smoke is still inhaled and the smell is unpleasant for the team. They, in turn, have largely given up the effort, especially when the suction source is noisy or simply ineffective. Despite these impediments to use, some hospitals, recognizing the beneficial effects of clean air for their staff, have invested in central vacuum or individual units which unfortunately often go unused except if hospital policy mandates their use by the O.R. staff.

Why the indifference of staff to the health hazards of smoke in the O.R. but not when it invades their non‐professional activities? Perhaps when they say, “Smoke is not a problem in my O.R.,” what they mean is…”There are no effective smoke capture devices so why should I bother?” This is akin to the coal miner that tolerates inhalation of coal dust because there are no alternatives to his making a living. After a number of years of exposure, he goes on to develop Black Lung Disease³¹. Allowing smoke‐filled O.R.’s is that much more inane when one recognizes that smoking is not allowed either in or outside of the hospital.

Perhaps what is needed to get the O,.R. nurse to use, if not become a champion of smoke evacuation, is a device that works; that is, a product that consistently provides clean air for the operating room. By definition, such a device must be capable of at least 95% smoke capture for prolonged periods of time without interfering with the surgeon’s protocols. Further, it should be simple for the nurse or surgical tech to use or apply to the patient, frees the team from involvement during the case and doesn’t obstruct the surgeon’s vision. To date, the methods available, notably the “wand” and the “ESU pencil” both have drawbacks. The wand requires a team member to chase the plume and commonly obstructs the surgeon’s vision although it collects smoke well if kept within 1” of the smoke source³². The ESU pencil, while convenient, causes hand fatigue, can interfere with vision and over time, has limited smoke capture ability³³.

The better solution may be a new device which has been introduced at trade shows four years ago³⁴ and which has none of the problems cited above. Independent testing at a leading air quality laboratory has confirmed that the product captures 99.5% of plume versus 51.4% by the ESU pencil³⁵. The product called, “miniSQUAIR®,” is applied to the skin, or covering drape, on one side the wound and is connected via tubing to a suction source capable of generating a minimum of 25‐35 cubic feet/minute (cfm) of air flow.

It is barely visible if placed beneath the surgical drape. Because of the flexibility of its cell foam core through which the smoke exits the wound, retractors can be used. It is disposed of as contaminated waste. It is made of fire retardant materials and its cost is modest. It is manufactured by Nascent Surgical, LLC of Eden Prairie, Minnesota and its expanded use is to be anticipated now that the device is readily available.

It promises to improve compliance by clinical staff to federal rules and guidelines which require a safe working space for employees. The improved air quality should, as shown in other environments, result in a lower rate of absenteeism with a subsequent reduction in manpower costs. Finally, the miniSQUAIR should limit the potential for worker’s compensation claims for respiratory and other illnesses related to exposure to contaminated air in the O.R. For example, the worker presents to the doctor for a respiratory illness. The doctor asks if there was any exposure to irritants such as smoke, chemicals, etc. The worker say, ‘Yes. I work in the operating room.” That claim could potentially cost three times the customary insurance premium over three years because of the impact on the “experience modification factor.”
