Electrosurgery produces surgical smoke. Different tissues produce different
quantities and types of smoke, so we studied the particle characteristics of this
surgical smoke in order to analyze the implications for the occupational health
of the operation room personnel. We estimated the deposition of particulate
matter (PM) from surgical smoke on the respiratory tract of operation room
personnel using clinically relevant tissues from Finnish landrace porcine tissues
including skeletal muscle, liver, subcutaneous fat, renal pelvis, renal cortex,
lung, bronchus, cerebral gray and white matter, and skin. In order to standardize
the electrosurgical cuts and smoke concentrations, we built a customized
computer-controlled platform. The smoke particles were analyzed with an
electrical low pressure impactor (ELPI), which measures the concentration and
aerodynamic size distribution of particles with a diameter between 7 nm and 10
?m. There were significant differences in the mass concentration and size
distribution of the surgical smoke particles depending on the electrocauterized
tissue. Of the various tissues tested, liver yielded the highest number of
particles. In order to better estimate the health hazard, we propose that the
tissues can be divided into three distinct classes according to their surgical
smoke production: 1) high-PM tissue for liver; 2) medium-PM tissues for renal
cortex, renal pelvis, and skeletal muscle; and 3) low-PM tissues for skin, gray
matter, white matter, bronchus, and subcutaneous fat.
