Abstract: The invention relates to a xenon-based anesthetic gas composition to be used, via inhalation, to maintain or preserve cerebral perfusion during an endarterectomy involving the clamping of the carotid artery in a mammal under general anesthesia. The xenon is preferably used in combination with at least one injectable anesthetic morphine agent such as remifentanil, sulfentanil, fentanyl, and alfentanil. Advantageously, the xenon is mixed with an oxygen-containing gas and administered to the patient after the patient has been anesthetized, put to sleep, and intubated. The use of xenon makes it possible to achieve a reduction in the pressure gradient during the clamping of the internal carotid artery relative to the usual anesthetic agents, and to achieve stable hemodynamics.
Abstract: The invention relates to an installation for filling gas containers (5) comprising at least one gas-container (5) filling system (2) comprising at least one gas-distribution device and connection means allowing the said device (1) to be connected fluidically to several containers (5) so as to fill the said containers (5) simultaneously with gas, for example a mixture of NO and of nitrogen. The gas-distribution device comprises a main body (1) with an internal gas-distribution chamber (3), a gas inlet orifice (11) fluidically communicating with the internal chamber (3) so as to allow gas to enter the said internal chamber (3) via the said inlet orifice (11), and several outlet orifices (12) fluidically communicating with the internal chamber (3) so as to allow gas to be discharged from the said internal chamber (3) via the said outlet orifices (12). The outlet orifices (12) are angularly distributed in the internal chamber (3).

Abstract: Methods for preserving technical products such as fuels and lubricants with a microbicidal composition. The composition is made up of at least one formaldehyde donor compound and at least one antioxidant. The antioxidant is either a gallic ester, a phenol derivative, a L-ascorbic acid, including salts and derivatives thereof, a tocopherol or one of its associated derivatives.
Abstract: A description is given according to the invention of a composition on an aqueous basis which comprises a) 0.001 to 10% by weight bispyridinium alkane, b) 0.1 to 30% by weight nonionic surfactant, c) 0 to 40% by weight aromatic alcohol and d) 0.01 to 10% by weight polyol selected from alkanediols and alkanetriols. The compositions, as mouthwash solutions, are more active than current commercial products and are distinguished by a pleasant taste and low tendency to foaming.

Abstract: The invention pertains to a method for packaging a gaseous NO/N2 mixture into a container comprising the steps of introducing into a container a gaseous premix formed of NO and of N2 containing an NO content of less than 10% by volume so as to reach a first pressure P1 with P1>1 bar, then introducing into the container containing the NO/N2 premix at the first pressure P1, gaseous nitrogen so as to obtain a final gaseous NO/N2 mix containing an NO content of less than or equal to 1200 ppm by volume and a second pressure P2 lying between P1 and 800 bar. The final NO/N2 gaseous mixture contains an NO content of less than or equal to 1000 ppm by volume.

Abstract: The method for packaging a gaseous NO/N2 mixture into at least one container, characterized in that, prior to admitting the said NO/N2 mixture, said at least one container is subjected to at least a purging step during which the internal volume of the container is placed in fluidic communication with the ambient atmosphere, an evacuating step during which the internal volume of the container is placed under depression, and a gas rinsing step during which an inert gas is admitted to said at least one container. For preference, the final gaseous NO/N2 mixture contains an NO content less than or equal to 1200 ppm by volume for a pressure of between P1 and 800 bar.
