Overview Nitrous oxide is a colorless and odorless substance that's also known as "laughing gas." When inhaled, the gas slows down the body's reaction time. We describe two cases of accidental deaths related to voluntary inhalation of nitrous oxide, both found dead with a gas mask covering the face. Expert Opin Drug Saf. Thus, reactions of a patient must be carefully observed to titrate the concentration of N2O. As a result, nitrous oxide is most commonly used in combination with other more potent inhalational anesthetics for general anesthesia. Releasing the nitrous oxide into a balloon helps to warm the gas and normalise the pressure before inhaling. Inhaled substances are rapidly absorbed into the brain to produce a quick high. Influence of methylenetetrahydrofolate reductase gene polymorphisms on homocysteine concentrations after nitrous oxide anesthesia. In other words, patients who are sedated by the inhalation of N2O through a mask are not only very receptive to being injected by a needle owing to the anxiolytic and analgesic effects of N2O (often being completely unaware of needling itself), but they may also not remember the injection. [1, 4], Nitrous oxide may also be useful for prolonged or more involved dental procedures as well as in patients with hyperresponsive gag reflexes. Nitrous Oxide | NIOSH | CDC Rosen MA. Whilst the risk of overdose from nitrous oxide is low people with heart conditions or abnormal blood pressure may be at higher risk as the drop in oxygen levels caused by inhaling the gas raises the heart rate, which could cause problems. Inhaled nitrous oxide versus placebo as an analgesic and anxiolytic adjunct to peripheral intravenous cannulation.

One newspaper claimed schoolies have been spending thousands of dollars on nitrous oxide. He described voices compelling him to keep consuming the drug. Moreover, the N2O inhalation sedation unit most widely used today (MDM, Matrx, NY, USA) has a minimum O2 concentration setting of 25%30% and has an O2 fail-safe system, in which the unit automatically shuts off the supply of N2O when the oxygen pressure drops below a certain preset level [22].

Neuropathy following abuse of nitrous oxide. [24] reported that three out of six atypical AEs were associated with apnea/O2 desaturation after recovery under room air when patients were supplied with 100% O2 for 23 minutes after cessation of N2O. N2O, an odorless and colorless gas, is very appealing as a sedative owing to its anxiolytic, analgesic, and amnestic properties, rapid onset and recovery, and, in particular, needle-free application. Symptoms appeared from after 2 days to even after 2 months, with the initial symptoms including symmetric paresthesia or numbness in the limbs, which gradually spread to the trunk to cause gait unsteadiness.
