Nitrous oxide-induced myeloneuropathy: a case series.

Preventable neurological harm from NO abuse is increasingly seen worldwide. Ease of access to canisters and larger cylinders of NO has led to an apparent rise in cases of NO-myeloneuropathy in several areas of the UK. Our results highlight the range of clinical manifestations in a large group of patients to improve awareness of risk, aid early recognition, and promote timely treatment.
