Can you be anesthesized for an MRI?

Yes. But it’s like getting geared up for a space flight.

Per some of the “answers” downstream of the first in your link…who says you can’t?

I too get plagued by random Straw Man-type questions on my feed. I wish someone would ask Quora “Why?”

For the heck of it, I just checked on what inanity Quora has conjured up to grab my attention today. Two so far and, before deleting them, I read…

"Does having a heart attack or stroke mean …?

“Why do the English …?”

Hmm…how on Earth does it know? :thinking::wink:

I almost find myself wondering what the end of the questions might be more than the alleged answers.

The hive mind doesn’t know everything. A year or more ago, I posted a question about the velocity of a particular generation of British Navy cordite, which I needed for some recoil calculations. No answer yet. I put the question on another forum and only one person even knew that velocity is a property of high energy materials, but he didn’t know the velocity of cordite.



I see your problem. The question looks as if it might be a serious one (from the perspective of knowing nothing about the topic, that is) I doubt anyone reading it thinks you’re a real person.

Well, let’s see.

Sitting in the navy warehouse, its velocity is zero.

On a ship enroute to the battle, it’s about 10 knots.

On the truck from the dock to the front lines, it probably averages something between 20 and 30 MPH.

It’s also moving with the earth around the sun at about 18.5 miles per second.

So sometimes you might need to be a bit more specific about your question.



I should add that asking a site like Quora for some bit of factual information like this is generally a waste of time. Answers are rarely backed with references, so you don’t really know if the answer is right or not.

Sometimes it takes a bunch of searching. And sometimes you can’t home in on the specific answer and instead have to rely on other answers from a similar time frame.

Here’s one of the first things that popped up on a Google search. It’s from 1894 about naval guns.

I think that article is talking about muzzle velocity.

Velocity of explosives is the rate of propagation of combustion. What separates “high” explosives from “low” explosives is the velocity. Cordite has a lower velocity than black powder. Touch off a pile of black powder and it goes poof. Touch off a piece of cordite, in open air, and it burns for several seconds. iirc, Tim talked about his ground pounder days, cooking supper over a piece of burning cordite. Containing the combustion speeds the reaction. Black powder naval guns tended to have short barrels, because the powder gave it’s kick very quickly, and a longer barrel would reduce range, due to friction of the projectile going down the barrel. With cordite, or USN smokeless, the combustion is slower, so a longer barrel becomes preferable, not only for better accuracy, but also to contain the combustion longer, so the cordite has time to burn completely.

From the Wiki article on velocity:

Typical for organic dust mixtures range from 1400 to 1650 m/s. Gas explosions can either deflagrate detonate based on confinement; detonation velocities are generally around 1700 m/s but can be as high as 3000 m/s. Solid explosives often have detonation velocities ranging beyond 4000 m/s to 10300 m/s.


Not really.

In my former practice we anesthetized pediatric cases for MRIs at least 3 days a week. The biggest thing for me to remember was to leave my watch, cellphone, and beeper (when I used to carry one) in the tech control room. We had a dedicated anesthesia machine and equipment cart that only had non-ferrous items. Outside of that, it was fairly business as usual but then again we did it all the time. Nothing too unusual that you don’t face in a regular OR setting.



I love your minutia.
