It seems likely that in man, in contrast to the rat, exposure
of less than 30 minutes will not cause any measurable change in
methionine synthase activity. In combination with a wealth of
clinical experience, this suggests that there is no special
hazard for short exposures to nitrous oxide. There is a variable
response to exposures lasting between 30 minutes and 2 h. However,
it now seems likely that exposures of more than 2 h are likely
to cause intereference with hepatic methionine synthase
activity. The paucity of human data makes it more difficult to
say how long an exposure is required to cause significant
intereference with DNA synthesis. It is likely that there will
be considerable individual variation and results obtained in
healthy patients cannot be extrapolated to the patient
who is seriously ill. Nevertheless, it seems likely that,
once methionine synthase activity is inhibited, it will remain
so for days.
