Recreational use or ‘nanging’ can lead to permanent neurological sequelae. Derangements in glutamate neurotransmission have been implicated in several neurodegenerative disorders including, stroke, epilepsy, Huntington's disease, Alzheimer's disease, and amyotrophic lateral sclerosis (ALS). In most cases of nitrous oxide Nitrous oxide SDS No. N 2 O prolonged and recurrent administration is known to affect vitamin B12 metabolism with subsequent clinical consequences. Methemoglobinemia is a condition where hemoglobin is unable to release oxygen effectively to body tissues, leading to hypoxia and cyanosis. That Nitrous oxide (N 2 O) toxicity has serious medical sequelae affecting both the CNS and the bone marrow. Instead, issues with toxicity are most often due to long-term exposure to the gas and decreased oxygen consumption. Bottom line => Have nitrous oxide toxicity on your differential in patients with Nitrous oxide, commonly known as "laughing gas", is increasingly being misused for recreational purposes. These intermediate products, formed prior to complete nitrate reduction and assimilation via the GS/GOGAT cycle, may play a role in nitrate-dependent toxicity mitigation. Medically reviewed by.
