nitrous oxide (N₂O, NOx)

[nī′trəs]

a colorless, odorless, sweet-tasting, weak anesthetic gas used in dentistry, surgery, and childbirth. It must be delivered with oxygen to prevent anoxia. Nitrous oxide alone does not provide enough anesthesia for surgery, for which it is supplemented with other anesthetic agents. It is often given during induction of anesthesia, preceded by the administration of a barbiturate or narcotic. Nitrous oxide is neither explosive nor flammable, and recovery is rapid. Nitrous oxide is not considered suitable for prolonged surgery or for surgery requiring deep muscle relaxation and is not administered to patients with hypoxemia, respiratory disease, or intestinal occlusion.

nitrous oxide a colorless, odorless gas that is a weak inhalational anesthetic, usually used in combination with a potent halogenated inhalational anesthetic to produce general anesthesia or briefly for dental surgery. Its use as a sole agent requires high concentrations that may cause hypoxia. abuse poses the risk of anoxic death from asphyxia. Popularly known as laughing gas.
