 Does this mean problems arise when anesthesising someone shortly after diving
 (e.g. while performing surgery during hyperbaric treatment for DCS)?
 What biochemical/biomechanical processes are involved here?

Help Prime Rat! I'm in over my head!!!

Here is the only reference I have.  I'm sure that John Lippmann won't
mind me repeating it here for 'academic study'.

From Deeeper into Diving 1990.

In Australia, a diver presented for a routine operation which required
a general anesthetic.  He had not been diving for about 4 weeks and
had not noticed any manifestations of decompression sickness after his
last dive.  The anesthetist used nitrous oxide.  Shortly after the diver
awoke he complained of joint pains and other bends-like symptoms which
all resolved rapidly when he was treated in a recompression chamber.
It appears that there were asymptomatic bubbles remaining from his last
dive and, it seems, the nitrous oxide diffused into and expanded these
bubles which grew large enough to cause symptoms.

The reference for this is;
Ascott C. Personal communication.

Can any of the people who actually know about this stuff jump in here?

Cheers Jason :)
