NITROGEN ZAKIS (Nitrogenium oxydulatum).

     Synonyms : Dinitrogen guard ide, Nitrous on xyde ON xydum nitrosum, R r t of ohu de d 'A z on t e Stickoxydal.

     Colorless gas is heavier than air (relative density of 1,527), a characteristic smell. Mg in water (1:2). When 0 C and a pressure of 30 atm, and the normal temperature and pressure of 40 atm learn in a colorless liquid. From 1 kg of liquid nitrogen oxide formed 500 litres of gas. Do not ignite, but supports combustion. Mixtures with ether, tsiklopropanom, hloretilom in certain concentrations of exploding.

     Small concentrations of nitrous oxide is a sense of intoxication (thus the name <laughing gas>), and lighter mood. Inhalation clean gas are rapidly growing drug status and asphyxia. In mixed with oxygen at the correct dosing is anaesthesia without anxiety and side effects. Nitrous oxide is a weak drug activity, and therefore it should be applied in high concentrations. In most cases, using combined anaesthesia with nitrous oxide, which combines with other, more powerful means to narcosis and muscle.

     Nitrous oxide does not cause respiratory tract irritation. In the body it is not modified, not associated with hemoglobin; Is dissolved in the plasma. After the end of inhaling available (through the full 10 - 15 minutes) through the respiratory tract unchanged.

     General anaesthesia with nitrous oxide used in surgical practice, the operational gynecology, dental surgery, and anesthesia delivery. <Clinical analgetichesky anaesthesia> (B. V. Petrovsky, S. N. Efuni) with a mixture of nitrous oxide and oxygen is sometimes used in the aftercare period for the prevention of traumatic shock, as well as edema in severe pain attacks coronary insufficiency, heart attack, acute pancreatitis and other pathological conditions involving pain, not kupiruyuschimisya conventional means.

     Applied nitrous oxide mixed with oxygen through special machines for gas narcosis. Usually beginning with a mixture containing 70-80% nitrous oxide and oxygen 30-20%, then the number of oxygen increases to 40-50%. If you are unable to obtain the necessary depth of narcosis, and the concentration of nitrous oxide in 1970-75%, add more powerful drugs : Halothane, broadcast, barbiturates.

     To better use muscle relaxation muscles, not only increasing the muscle, but also improved during narcosis.

     Following the filing of nitrous oxide should avoid hypoxia continue to provide oxygen for 4-5 minutes.

     Apply nitrous oxide should be cautious when expressed events hypoxia and violation of diffusion of gases in the lungs.

     For anesthesia delivery methodology broken autoanalgezii with through special anaesthetic machines mixture of nitrous oxide (40-75%) and oxygen. Pregnant begins to inhale a mixture of skin foreshadowing battle and ends at the height of battle, inhalation or its end.

     To reduce the emotional state, preventing nausea and vomiting and potentiation of nitrous oxide sedation can intramuscular a 0.5% solution of diazepam (seduksena, sibazona) in the number of 1-2 ml (5-10 mg), 2-3 ml of 0.25% droperidola solution (5.0-7.5 mg).

     Clinical anaesthesia nitrous oxide (with strokes and heart attacks) is not suitable for serious diseases, nervous system, chronic alcoholism, drunk (possible excitation, hallucinations).

     Product : in metal containers with a capacity of 10 litres at a pressure of 50 atm of curdled (liquid) state. Cylinders grey and have marked <For medical applications>.

     Storage : Keep at room temperature in a closed room, away from the fire.
