In experimental settings, electrodesiccation has been associated with transmission of human papillomavirus (HPV), hepatitis B virus, and Staphylococcus aureus. Some people erroneously think that the heat induced by electrocoagulation sterilizes the electrode tip. This is true in electrocautery where heat is generated in the tip but not in electrocoagulation where heat is only produced in the tissue. Special precautions in the form of facial masks, protective eye wear, and a smoke evacuator should be used when treating HPV-related lesions, since HPV can become aerosolized in blood microdroplets and in electrosurgical smoke posing a risk to the patient, physician, and surgical staff (Fig. 16-5).29โ31
