Area of Science:

  • Dermatology
  • Infectious Disease
  • Occupational Health

Background:

  • Laser resurfacing procedures generate smoke plumes.
  • Concerns exist regarding biological hazards for operating room personnel.
  • The specific risks of bacterial and viral exposure from CO2 laser smoke plumes are not fully understood.

Purpose of the Study:

  • To analyze potential bacterial and viral exposure to operating room personnel.
  • To assess the biological hazards associated with CO2 laser resurfacing smoke plumes.

Main Methods:

  • Thirteen patients undergoing CO2 laser resurfacing were studied.
  • Laser plume smoke was collected using a HEPA filter in a smoke evacuator.
  • Control specimens were obtained from filters exposed to room air.

Main Results:

  • No viral growth was detected in any specimens.
  • Bacterial growth was identified in 5 out of 13 bacterial cultures.
  • Specific bacteria identified included coagulase-negative Staphylococcus, Corynebacterium, and Neisseria.

Conclusions:

  • Operating room personnel may be exposed to viable bacteria during laser resurfacing.
  • Laser smoke plumes pose a potential infectious risk.
  • Further precautions may be necessary to mitigate bacterial exposure.
