I want a source for a comprehensive list of American manufacturers of
anesthetic gases, either a free online database or one which will
deliver this company information for a reasonable price. There is no
specific SIC or NAICS number; Thomas Register is unreliable, and other
databases I have access to, such as CorpTech, do not pinpoint this.

This site appears to have a complete list of US manufactures
www.iomaweb.org/lin.html#Sec2. I found that some of links would not
work, but the companies listed are those manufacturing anaethetic
gases.

The answer supplies manufacturers of oxygen, not anaesthetic gases.
The comment from seedy provides a better answer, although not a
comprehensive one. I don't believe I should be charged for this
answer.

Additional information about anesthetic gases as follows:

   Inhaled Anesthetics
"Many adults may remember having ether for their anesthetic when they
were young. Ether is a flammable anesthetic that is no longer used in
the United States. Today, the commonly used inhaled anesthetics are
nitrous oxide (also known as laughing gas), sevoflurane, desflurane,
isoflurane and halothane.

Why do we have so many different kinds of gases? Because each gas has
its own special properties. For example, sevoflurane and halothane are
easy to inhale while desflurane is very irritating to inhale and has a
shorter duration of action. If you need to breathe yourself to sleep,
halothane or sevoflurane would be easiest to inhale. If a very
short-acting anesthetic is needed, the anesthesiologist can switch to
desflurane after you fall asleep. Nitrous oxide is easy to inhale, but
when used alone is not potent enough to be a complete general
anesthetic. However, it can be used alone for sedation, or combined
with one of the other inhaled anesthetics or injected liquid
anesthetics for general anesthesia.

These gases have different effects on other organs as well. For
example, halothane may cause the heart rate to slow down and the blood
pressure to decrease while desflurane may cause the heart rate to
speed up and the blood pressure to increase. How do these inhaled
anesthetics reach the brain? When an anesthetic gas is inhaled into
the lungs, the blood that travels through the lungs carries the
anesthetic gas to central nervous system cells. The rate at which the
bloodstream takes up the anesthetic is dependent on many factors
including the concentration of the inspired gas, the rate of flow of
the gas from the anesthesia machine, the solubility of the gas in
blood, the rate and depth of breathing, and the amount of blood the
heart pumps each minute in the person breathing the gas.

An important property of anesthetics is reversibility. When the
surgery is over, the anesthesiologist wants to shut off the anesthetic
and have the patient wake up from the anesthetic-induced sleep. Once
the anesthetic gas is turned off, the blood stream brings the gas back
to the lungs where it is eliminated. The more soluble the gas is in
blood, the longer it takes to eliminate. Nitrous oxide and desflurane
are the shortest-acting anesthetic gases because they are the least
soluble in blood."

The website that was most helpful in identifying the suppliers of
these gaseous anesthetics was as follows:

    http://www.pain.com/painexpo/px_genericname.cfm

I know I found the quote that starts the comment and which identified
the commonly used anesthetics but I have lost the link to
it....Sorry..

Hi dgc,

Here are some more resources for helping you find suppliers of
anesthetic gases. As you noted, this is a very fragmented market. I
tried to find portals where someone might have collected resources,
including vendor/supplier lists, for anesthesiologists. I hope some of
these will meet your needs.
