Contamination of the operating room by waste anesthetic gases

Cytogenetic Damage in Operating Room Nurses Exposed to Anesthetic Gases

Background: Although eliminated rapidly from the body due to low solubility in blood and tissues, anesthetic gases have been reported to be neurotoxic, teratogenic and carcinogenic. Genetic material has been shown to be a sensitive target of numerous harmful agents. Aim of the Work: To evaluate genotoxic risk of occupational exposure to anesthetic gases in a group of operating room nurses. Subj...

Assessment of adaptive response of gamma radiation in the operating room personnel exposed to anesthetic gases by measuring the expression of Ku 80, Ligase1 and P53 genes

Introduction: Staffs of operating room are continuously exposed to anesthetic gases and                                                       ionizing radiation. Adaptive response, as a defense mechanism, will occur when cells become exposed to a low dose of factors harming DNA that causes in the next exposures to higher doses o...

Assessment of Adaptive Response of Gamma Radiation in the Operating Room Personnel Exposed to Anesthetic Gases by Measuring the Relative Gene Expression Changes Ku80, Ligase1 and P53

Background: Some operating room personnel are occupationally exposed to genotoxic agents such as anesthetic gases and ionizing radiation. Adaptive response, as a defense mechanism, will occur when cells become exposed to a low dose of factors harming DNA (priming dose), which in the subsequent exposure to higher dose of those factors (challenging dose), show more resistance and sensibility.. <b...

St1b Waste Anesthetic Gases: the Invisible Threat

Waste anesthetic gases (WAGs) can be defined as all halogenated organic compounds (including methoxyflurane, halothane, isoflurane, sevoflurane, desflurane, and enflurane) and nitrous oxide that escape from the anesthetic circuit, or are exhaled by the patient. Management of WAGs intuitively seems prudent, but because excessive exposure is often difficult to detect without special monitoring de...
