Research of medical gases is well established in Poland and has been marked with the foundation of several professional societies. Numerous academic centers including those dealing with hyperbaric and diving medicine conduct studies of medical gases, in vast majority supported with intramural funds. In general, Polish research of medical gases is very much clinical in nature, covering new appli...

AANA Journal ß October 2010 ß Vol. 78, No. 5 387 Discovered in 1898 by British chemists, xenon is a rare gas belonging to the noble gases of the periodic table. Xenon is used in many different ways, from high-intensity lamps to jet propellant, and in 1939, its anesthetic properties were discovered. Xenon exerts its anesthetic properties, in part, through the noncompetitive inhibition of N-methy...

statistics have shown that the incidence of miscarriage among nurse anesthetists and anesthesiologists who were pregnant before being em­ployed was 10% while those who were pregnant during their employment were 20%. this was attributed to the teratogenic effect of anesthetics agents used in the operating room on the fetus. today with the use of special askrog valve, 90% of the anesthetic gases ...

Through the use of an automatic photo tube dew-point hygrometer, the author succeeded in measuring dew point of gas flows continuously in anesthetic circuits. Simultaneous thermometries were done on the nasal or oral mucosa, on the respiratory gas flows in the anesthetic mask or the endotracheal tube, and on the gas in the inhaling conduit. Experiments were performed on ten adults patients unde...

AN electrochemical sensor has previously been reported to provide useful detection of carbon monoxide while exposed to one minimum alveolar concentration of volatile anesthetics. My independent laboratory study yields further evidence supporting the possible utility of electrochemical carbon monoxide sensor measurements in anesthetic gas mixtures. Several scientific investigations have elucidat...

BACKGROUND Nonimmobilizers are structurally similar to anesthetics, but do not produce anesthesia at clinically relevant concentrations. Xenon, krypton, and argon are anesthetics, whereas neon and helium are nonimmobilizers. The structures of noble gases with anesthetics or nonimmobilizers are similar and their interactions are simple. Whether the binding site of anesthetics differs from that o...
