Official Luthiers Forum!

The local allows for a more shallow general. If they didn't give you the local, they would have to put you further under.

John is basically correct. I sent you a PM for details.
In the US it is a confidentiality issue.

The internet is great and awful at the same time. A little knowledge is
dangerous thing.
Totally unrelated to lutherie, but here we go for clarification purposes.
Recall or awareness can occur during an anesthetic but is VERY
uncommon. It is more common in heart surgery because of the
anesthetics we use. The best drugs to prevent recall are a type of
anesthetic that some patients with heart disease don't tolerate very well
even though they are used on almost 100% of all cases. (Inhaled
anesthetics such as isoflurane) Since these drugs can effect the function
of the heart, they are used in a limited basis in patients having heart
surgery. Other anesthetic agents that are well tolerated by the heart are
used in higher doses instead. These agents, (narcotics specifically) are
awesome for pain relief but are weak in amnestic properties. (recall is
more likely) Hopefully this makes sense. Anesthesia is very safe, but not
without some risk. This should be well describe to you BEFORE surgery. I
specialize in children with congenital heart disease, so this is what I do
everyday....unless I have a guitar to build.

Andy, at the risk of completely hijacking this thread (which I've already done) can you explain the dangers of "recall". thanks P

Recall in of itself is not physically dangerous. It strictly mean that you
have awareness during surgery. Usually when it happens, you are not in
pain. As mentioned above it is more common in heart surgery patients
and in trauma patients where the "better" anesthetics to prevent recall are
not tolerated. (But still rare) In this situation the analgesic type
anesthetics are usually tolerated. So...you may remember something but
you probably didn't hurt. In this situation, you may not even be able to
move or do something to give the anesthesiologist a clue to the fact that
it is happening. This is because other anesthetic agents that prevent
movement are also being used. For some this can be a psychologically
difficult to handle and may require therapy to deal with it. We obviously
try to prevent this but it is sometime difficult. There is no magical
monitor that we can use to monitor patient awareness. There are some
brain activity monitors that we use that are pretty good but they are not
foolproof.
I know that this next quote may be a bit hard to handle but it is really
true. "better off with a chance of recall than no chance at life" This hits
to the heart of the matter. I will ALWAYS use safer drugs to keep a
patient alive and take the risk of recall than put a patient as risk of death
to try to prevent recall. Each anesthetic is not just giving one drug to a
patient. I may use as many as a dozen different drugs depending on the
patient and the surgery. It is a matter of tailoring it to the specific
situation and balancing relative risks and benefits.
Don't let this discussion freighten you about anesthesia. 99.99% of the
time it is very straight forward and very safe.
