“…12 The bimodal distribution of particles produced by surgical instruments has been described previously. 3 The smaller spherical particles result from vaporization followed by nucleation, a process by which vapors are converted to tiny particles (droplets) of fluid. These particles contain sodium, chloride, potassium, magnesium, calcium, and iron and are produced by uniform drying of liquid dropplets in a gas flow.…”

“…Energy-dispersive spectrometry shows these particles to contain carbon and oxygen. 3 We calculated laparoscopic visibility in the presence of smoke produced by various surgical instruments using the measured size-distribution data and the Rayleigh and Mie light-scattering theories. 5 Rayleigh scattering of light by particles smaller than the wavelength of the light and occurs when light travels in transparent gases.…”

“…At present, there is a paucity of data regarding the morphology, size, and composition of surgical smoke. [1][2][3] Also, the effects of smoke on laparoscopic visibility have not been quantified. The objective of this study was to characterize the smoke produced by four commonly used energy-based laparoscopic instruments.…”

(2007 ABSTRACT Purpose:We analyzed the smoke plume produced by various energy-based laparoscopic instruments and determined its effect on laparoscopic visibility. Materials and Methods:The Bipolar Macroforceps, Harmonic Scalpel, Floating Ball, and Monopolar Shears were applied in vitro to porcine psoas muscle. An Aerodynamic Particle Sizer and Electrostatic Classifier provided a size distribution of the plume for particles Ͼ500 nm and Ͻ500 nm, and a geometric mean particle size was calculated. A Condensation Particle Counter provided the total particle-number concentration. Electron microscopy was used to characterize particle size and shape further. Visibility was calculated using the measured-size distribution data and the Rayleigh and Mie light-scattering theories.Results: The real-time instruments were successful in measuring aerosolized particle size distributions in two size ranges. Electron microscopy revealed smaller, homogeneous, spherical particles and larger, irregular particles consistent with cellular components Conclusions: Surgical smoke is composed of two distinct particle populations caused by the nucleation of vapors as they cool (the small particles) and the entrainment of tissue secondary to mechanical aspects (the large particles). High concentrations of small particles are most responsible for the deterioration in laparoscopic vision. Bipolar and ultrasonic instruments generate a surgical plume that causes the least deterioration of visibility among the instruments tested.

“…However, the smaller the particles, the deeper inhaled into the respiratory tract. For example, particles 7 µm or smaller can be deposited in the alveoli and include viruses and bacteria (Altree-Williams, Altree-Williams, & Marsh, 1998;DesCoteaux, Picard, Poulin, & Baril, 1996). Concern about respiratory exposure is warranted.…”

“…Many previous studies have focused on particle characterization in surgical smoke and its infection risks. Mowbray et al (2013) systematically reviewed 20 full-text articles addressing surgical smoke and found that common end points were particle size (DesCoteaux et al, 1996;Bruske-Hohfeld et al, 2008;Andreasson et al, 2009) and infection risk (Kunachak et al, 1996;Capizzi et al, 1998;Hughes and Hughes, 1998). It is in relatively recent years that the chemical composition in surgical smoke such as volatile organic compounds (VOCs) has been investigated.…”

The objective of this study is to analyze the volatile organic compounds (VOCs) in the surgical smoke generated during laparoscopic surgery, and determine their influence on the indoor air quality in hospital operating rooms (ORs). Field measurements were carried out during eight surgeries in conventional and robotic ORs in which an electrosurgery system was being used, thus continuously generating surgical smoke. The VOCs were measured at three different locations, in the patients' abdominal cavities, beside the surgical table, and at the exhaust vent. Other indoor pollutants including carbon monoxide (CO), carbon dioxide (CO 2 ), and total airborne bacteria (TAB) in the indoor air were measured at the exhaust to assess the general indoor air quality in the ORs. The results from the patients' abdominal cavities confirmed that the surgical smoke contained abundant VOCs, with the levels of benzene and toluene exceeding the health guidelines. Compared to the results obtained in the abdominal cavity, the measurements obtained at the surgical table and exhaust vent exhibited low levels of VOCs, indicating that the actual exposure to these compounds was minimized in a highlyventilated operating room. However, the benzene concentration in the operating room approached a level that threatens the health of the occupants. Therefore, the results of this study suggest that there is a potential health risk to the surgeon who is closest to the point of origin of the surgical gas, as well as a need for further attention to identify the local pollutant dispersion near the surgical table while the ventilation system is operating.

Preliminary study of electrocautery smoke particles produced in vitro and during laparoscopic procedures

Abstract: This study demonstrates the presence of breathable aerosols and cell-size fragments in the cautery smoke produced during laparoscopic procedures. Their exact chemical composition and potential adverse effects for patients and personnel are not known.
