Wound infection The administration of nitrous oxide reduces oxygen concentrations, which may increase wound infection rates.

WebbThe toxic effects of nitric oxide are mediated through oxidation of cobalt ions in vitamin B 12 and hence cause its inactivation. This leads to reduced recycling of homocysteine to methionine. This prevents methylation of myelin proteins, thus causing demyelination within the central and peripheral nervous systems.
