Abstract
This study developed a nano-filter to reduce the concentration of hazardous substances in surgical smoke. The nano-filter consists of nanomaterials and hydrophilic materials. Smoke was collected before and after using the new nano-filter during the surgery. The concentration of PM2.5 and PAHs produced by the monopolar device was the highest (P < .05). The concentration of PM2.5 and PAHs after using a nano-filter was less than the non-filter group (P < .05). Surgical smoke generated by monopolar and bipolar devices pose a potential cancer risk to health staff in the operational room. The concentration of PM and PAHs were reduced and the cancer risk was not obvious by using the nano-filter.
