- nitrous oxide/wisdom tooth report
- It started with the foul-tasting anesthetic spray. (Well, it really started
- with the panoramic x-ray, but that's boring. "Bite down on this, hold onto
- these, breathe in, and swallow...") By the time they asked me if I wanted
- nitrous oxide, it was already difficult to speak due to rubbery lips and
- tongue. I was reluctant, but decided to give it a try.
-
- Lying down on the operating table. They strapped a tube over my nose, and I
- felt panic as I came close to fainting, and breathed through my mouth for a
- while until the world was visible again. Fading vision was replaced by a
- feeling of detachment, tingling and slight numbness in my arms and legs, and a
- loud buzzing-humming-rushing noise which soon either faded away or I learned to
- ignore it. I then spent almost the entire time of surgery planning how I would
- describe what nitrous consciousness is like.
-
- It felt a lot like lucid dreaming, or like the half-dreaming state on lazy
- weekend mornings. There was a similar sense of distance from my perceptions.
- I could feel, hear, see everything, but it just wasn't my main concern. After
- I had been breathing NO2 for a few minutes, the dentist came in to inject the
- deep anesthetics. He warned me that it would hurt (I could barely hear him
- through the haze) and it did, and I thought yup, that hurts.
-
- My top stream-of-consciousness -- the talking-to-myself kind of consciousness
- -- was much more lucid than in a dream, pretty close to wakefulness... but not
- quite there. I felt that I could think almost as clearly as ever, though I was
- aware of being easily distracted (like when half asleep), and obviously the
- most important effect was the lack of interest in the physical world. Every
- once in a while I checked the clock (over the foot of the bed), partly to check
- my perception of time (usually about the same as normal consciousness, except
- when I got distracted) and partly just to make sure I could still focus my
- eyes. I couldn't converge the double image, though. I also wiggled my feet
- and fingers whenever they started to feel like they weren't attached any more.
-
- At some point the surgeon removed my two upper wisdom teeth. I never
- noticed... it must have been easy, so I may have missed it in the much more
- complex process of smashing the two lower teeth to bits with hammers, drills,
- and levers. Whenever I smelled burning enamel or heard the sharp CRACK of
- another chunk being pried off, I thought "I sure am glad I opted for nitrous.
- This wouldn't have hurt much, but it would have scared the heck out of me. As
- it is, I just don't care." The surgeon frequently made requests... open
- wider... turn your head this way... that way... they seemed to drift into my
- consciousness from a distance, and though I was intellectually aware that he
- was right there, it didn't feel that way. I wondered what would happen if I
- refused to obey-- would he think I had fallen asleep?-- but I never refused. I
- wondered what would happen if I bit down on the drill-- but I never did. I
- wondered if people under nitrous would be more susceptible to suggestion--like
- hypnosis--because I had heard that people following hypnotic suggestions had
- similar thoughts: "I could refuse to obey... but I don't feel like it." I had
- all these thoughts and metathoughts--including this one--while under the gas,
- which is why I say I was nearly lucid the whole time. I was always aware that
- I was drugged, and that I felt lucid, and that it was possible that what I
- thought was lucidity at the time really wasn't. But on reflection, breathing
- plain old oxygen and nitrogen now, I don't think I was deceiving myself.
-
- When I thought of it, I tried little tests of my consciousness. Could I
- recite pi to 16 digits? I could. Could I sing my favorite rounds to myself?
- I could and did, but one round got fixed in my mind and didn't go away until
- I'd been breathing atmosphere for fifteen minutes. I was also aware that I was
- having difficulty thinking of tests, and wondered if that itself was a symptom.
- I wish now that I had thought of testing my visual and aural imagination,
- which is always much more powerful in a half-dream state. I thought, if they
- put this stuff in the air in long plane trips, they would seem to go by a lot
- faster! I wondered if I would seek out illicit nitrous trips in the future,
- and eventually decided that I probably wouldn't, because the chief attraction
- was in avoiding confronting a very unpleasant situation (oral surgery). It
- wouldn't be good for parties, and I couldn't imagine bringing it with me to
- wait in line at the bank or some such.
-
- I was hoping to write more about that particular feeling- which is what makes
- it such a good surgery drug- but I'm having trouble figuring out how to
- describe it. Although I've said I was almost fully aware of everything that
- happened, that's obviously not really true. After all, I missed two
- extractions entirely. I felt very sleepy the whole time (a rather different
- feeling from the near-fainting when I first started the gas), and several times
- realized that the reason I was having trouble seeing was that my eyes were
- nearly closed. I fought against sleep; I didn't want to be unable to respond
- to the surgeon's instructions. I may have missed a lot during these episodes.
- I know from my clock-watching that I never lost self-awareness for more than 3
- or 4 minutes at a time. I think the most useful thing I can say about nitrous
- consciousness is that my internal mental life became much more important than
- my physical state, like reading an absorbing book while the radio is chattering
- away in the background.
-
- It took at least 20 minutes after being disconnected from the gas (and I felt
- a definite pang of regret when they took the tube off my nose... is it over
- ALREADY? Total gas time about 25 minutes) before I felt like I was mostly free
- of nitrous consciousness. Some of that may have been the influence of the
- anesthetics, though, which took over three hours to wear off completely. As I
- mentioned before, I tried to keep careful track of time, mostly to prove that I
- could. To my great regret, I forgot to ask in advance if I could keep the
- extracted teeth, and they were medical waste by the time I got around to it.
- Maybe they'll wash up on the Monterey coast sometime soon.
-
- Later I took a codeine pill and spent the next few hours fainting and
- vomiting, but that's another story. No more codeine for me.
