BACKGROUND The aim of this study was assessment the risk management status of waste anesthetic gases in academicals hospitals in Iran to prevent from harmful effects of these gases on employees' health. METHODS A descriptive-analytic study was designed in 2011. Standard structured checklist developed by ECRI institute (Emergency Care Research Institute) was applied. Checklists were filled ons...

Acute brain injury is a critical and emergent condition in clinical settings, which needs to be addressed urgently. Commonly acute brain injuries include traumatic brain injury, ischemic and hemorrhagic strokes. Oxidative stress is a key contributor to the subsequent injuries and impedes the reparative process after acute brain injury; therefore, facilitating an anti-oxidative approach is impor...

The typical setup for administering volatile anesthetics to laboratory rats does not provide for humidification of the inspired gases, although it is known that failing to provide humidification can lead to airway inflammation and impaired pulmonary function during prolonged experimental protocols. We developed a simple humidification system in which a nebulizer was inserted into the nonrebreat...

The relationship between exposure to trace concentrations of waste anesthetic gases in the operating room and the possible development of adverse health effects has concerned health care professionals for numerous years. Results of studies have been conflicting. In the late 1960s and early 1970s, some US and European epidemiological studies of operating room personnel showed an increase in the ...

Patients with malignant hyperthermia experience an exaggerated metabolic response when exposed to volatile anesthetic gases and succinylcholine. The minimum concentration of anesthetic gas needed to trigger a malignant hyperthermia crisis in humans is unknown and may remain so because of the inherent risks associated with studying the complex nature of this rare and lethal genetic disorder. The...

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...

BACKGROUND Potent inhaled anesthetics degrade in the presence of the strong bases (sodium hydroxide or potassium hydroxide) in carbon dioxide (CO2) absorbents. A new absorbent, Amsorb (Armstrong Medical Ltd., Coleraine, Northern Ireland), does not employ these strong bases. This study compared the scavenging efficacy and compound A production of two commercially available absorbents (soda lime ...
