What is one potential side effect of prolonged use of nitrous oxide?

Prolonged use of nitrous oxide can lead to a vitamin B12 deficiency. This occurs because nitrous oxide has the ability to oxidize vitamin B12, disrupting its function in the body. Vitamin B12 is essential for brain function and the production of red blood cells, and its deficiency can lead to neurological impairment and anemia.

While hypoxia, increased blood pressure, and tachycardia can result from various factors associated with anesthesia, they are not specifically attributed to the prolonged use of nitrous oxide in the same way that vitamin B12 deficiency is. Therefore, understanding the impact of nitrous oxide on vitamin B12 metabolism is crucial for managing patients receiving sedation and ensuring their overall health.
