Anaesthetic gas Scavenging
نویسنده
چکیده
ThEATRE Possible adverse health effects are an increased risk of spontaneous abortion in females, the increased likelihood of male anaesthetists to father daughters, decreased fertility, a potential increase in haematological malignancy, renal and liver dysfunction and decreased mental performance. One explanation for these effects is inhibition of methionine synthase by nitrous oxide, causing impairment of deoxyribonucleic acid (DNA) synthesis. However the evidence for these effects is not robust, with studies giving conflicting results.

Hydrodynamic evaluation of a new anaesthetic gas scavenging system.
A new anaesthetic gas scavenging system is described. The resistance of the system appears to be low. When input gas flow rate in the system was zero or 150 litre min-1, misuse of the system produced pressure changes at its collecting points of 26 Pa subatmospheric and 630 Pa above atmospheric pressure, respectively. Suggestions to develop the system and increase its safety are presented.
متن کاملOperating room air pollution: influence of anaesthetic circuit, vapour concentration, gas flow and ventilation.
Atmospheric halothane was sampled from three selected operating theatres and anaesthetic rooms during the middle of operating sessions. Two of the operating theatres studied were ventilated with total air exchange once every six minutes; the third operating theatre had no ventilation. End-tidal samples were obtained from anaesthetists. Halothane vapour concentrations were analysed by gas-liquid...

Adjustable pressure limiting (APL) valve Allows fo...
متن کاملP110: Nitrous Oxide and Neuroinflammation
Nitrous oxide was an anaesthetic gas that was used for many years. There were many anaesthetic drugs in operations with many side effects. Nitrous oxide had some side effects too. But it was a safe gas in many times. In hospital personnel who worked in operating rooms exposure to this gas was important. The objective of this study was the introduction of nitrous oxide and neurologic side ...
متن کاملThe Leiden scavenging system: A simple and versatile apparatus to control air pollution in operating rooms.
A scavenging system which can be attached to a variety of anaesthetic machines and ventilators is described. Gas venting can occur via a central vacuum system, a suitable injector, fan or pump, through the exhaust duct of an air-conditioning system, or by a passive system. The resistance and back pressures applied to the anaesthetic apparatus are negligible. Leakage tests showed that the collec...
متن کاملThe wide-range ejector flowmeter: calibrated gas evacuation comprising both high and low gas flows.
The wide-range ejector flowmeter is an active scavenging system applying calibrated gas removal directly to the anaesthetic circuit. The evacuation rate can be adjusted on the flowmeter under visual control using the calibration scale ranging from 200 ml X min-1 to 151 X min-1. The accuracy of the calibration was tested on three ejector flowmeters at 12 different presettings. The percentage dev...
