Peripheral neuropathy, optic atrophy, and dementia can also occur. Pathology Neurotoxicity is secondary to the selective inhibition of vitamin B12 hydroxocobalaminwhich serves as a oxidee for methionine synthase, which is an enzyme active in folate metabolism and the formation of myelin sheath phospholipids 2,4.

Toxicity of nitrous oxide

But in the case of overuse or misuse, nitrous oxide can be dangerous and life-threatening. His nerve biopsy showed no primary demyelination but there was large myelinated fibre loss hence nirtous conduction velocities with multiple small vessel occlusions and ischaemic pathology without vessel infiltration. Mixing drugs can also increase the risk of passing out and suffocating or chocking on vomit.

Inform antenatal staff, or your local doctor, of any drug use and attend regular antenatal check-ups. MR scan of brain and whole spine and nerve conduction studies were normal. On examination, his muscle tone was flaccid and he had symmetrical proximal and distal nitrou of the lower and upper limbs with a glove and stocking sensory loss. His symptoms progressed over a few days to paraesthesia in nitrouus fingers, and difficulty with walking and performing fine tasks with his hands.

You should also: if the person is unconscious, put them on their side, in the recovery position stay with the person check their breathing, clear their airway do mouth-to-mouth resuscitation if they stop breathing If the person has been mixing nitrous oxide with other drugs, tell the NSW Ambulance paramedic exactly what they have taken.
