The types and quantities of aerosols produced during surgical procedures to which surgical personnel would be exposed were studied as part of investigations to determine whether operating room personnel can be infected by an aerosol containing a pathogen such as the human immunodeficiency virus. Aerosol samples were collected during a simulated hip replacement procedure in dogs in the laboratory, and during human total hip replacement in an operating room. Preliminary findings showed that relatively low concentrations of aerosol were produced and that a large fraction of the aerosol was in the respirable size range. There was a high degree of variability in exposure among the personnel present. The aerosol had a multimodal size distribution with each mode attributable to the use of a given surgical tool. Electrocautery produced an aerosol with a relatively small particle size. Measurement of hemoglobin with the CHEMSTRIP 9 was a sensitive means of determining the amount of blood in the aerosol.
