Nitrous oxide is a colorless and sweet gas, also called nitrous oxide, which is an oxidant with the chemical formula N2O. Nitrous oxide can support combustion under certain conditions (like oxygen, because nitrous oxide can be decomposed into nitrogen and oxygen at high temperature), but it is stable at room temperature and has a slight anesthetic effect, which can make people laugh. It can be dissolved in water, ethanol, ether and concentrated sulfuric acid. Its anesthetic effect was discovered by British chemist humphry davy in 1799. This gas was used for anesthesia in dental surgery at an early stage. Laughter is one of the earliest anesthetics used in medical treatment. This is a colorless gas. People can't help laughing after inhaling, which has anesthetic effect. It can be produced by decomposition of NH4NO3 under slight heat, and there is another product besides N2O. The chemical equation of this reaction is) NH4NO3->; N2O ↑+ 2H2O; According to related theories, N2O and CO2 molecules have similar structures (including electrons), so their spatial configurations are linear and N2O is polar.
Alias laughing gas; Nitrous oxide
English name nitrous oxide
Medical indications are often used in combination with halothane, methoxyhalothane, ether or intravenous general anesthesia because of poor general anesthesia effect. It is used less now.
Dosage and usage of drug inhalation: The dosage depends on the needs of surgery and the patient's condition.
Medical precautions 1. Major surgery needs to be combined with thiopental sodium and muscle relaxants; The oxygen concentration in the inhaled gas should not be less than 20%; After anesthesia is terminated, pure oxygen 10 minute should be inhaled to prevent hypoxia. 2. When the patient has hypovolemia, shock or obvious heart disease, it can cause severe hypotension. Nitrous oxide may also be harmful to patients with pulmonary embolism.
Specification gas for medical drugs: packed in pressure-resistant iron cylinders.
Can't be used as fuel
