Esposizione a gas anestetici: Risultati di 13 anni di monitoraggio ambientale e biologico in un azienda ospedaliera

The evolution of the modern anaesthesiologic technique aimed to detect more manageable and less toxic aesthetic gas, but adequately efficacy. This study considered the environmental and biological evaluation of the Careggi Hospital in Florence between 1991 and 2005. The pollution threshold of each aesthetic gas used (Nitrous oxide, Isoflurane and Sevoflurane) is reduced as time passed. The higher values about the pollution threshold have been found in the ophthalmology and in the othorinolaryngology operating room. We observed clinical and biological data of 74 health care workers (HCW). The anaesthetists and assistants were the more exposition. We didn't found any correlation between the exposure at gas and the clinical, and biological data. Some neurological and nonspecific symptoms (like head-ache and reduction of attention threshold) appear from the clinical informations; these symptoms suggest a possible effects on the HCW' health also for low pollution threshold.
