When you're dealing with major surgeries—the kind where they really need to knock someone out so there's zero movement—you're looking at full general anesthesia. It’s basically a cocktail of sedatives mixed with muscle relaxants, like those old movies where the warriors use blowguns to paralyze their targets, plus heavy-duty painkillers. If an anesthesiologist slips up, things get terrifyingly real; there's that nightmare scenario where a patient can actually feel everything happening but is completely paralyzed and unable to scream or even twitch. Plus, with total anesthesia, you have to rely on a ventilator to do all the breathing for you, which means sliding a tube down the throat—and honestly, there's always that nagging worry about accidental dental damage during the process.
So, you’ve got local anesthesia, which can be paired up with some light "twilight" sedation—basically using different sedatives to knock a patient out for a bit. We only ever go that route if there's zero risk of them vomiting, because if they do, all that stomach acid ending up in the lungs is a total nightmare and can actually be fatal. You can mix this kind of sedation with things like spinal anesthesia, which is honestly a whole story on its own, but we don't really consider it for major surgeries; it's mostly just something used for procedures on the lower extremities.
So, you’ve got spinal anesthesia, which basically means we're doing a block in the lower part of the spine. It’s a pretty straightforward procedure that knocks out all sensation from, say, the belly button down. The patient stays wide awake through the whole thing, so if they're feeling a bit jittery, I usually toss in some sedative to help them chill out.
So, think of an epidural as being pretty much the same technique as a spinal, just with a smaller dose involved. It’s not really full-blown anesthesia so much as it is analgesia—basically, it just takes the edge off the pain instead of knocking you out completely. If you crank up the concentration, though, you're essentially turning it into a spinal. You see it used all the time for labor and delivery, or just to help people manage pain after surgery.
I honestly think you might be getting a few of these terms mixed up...
Honestly, epidurals and spinals aren't even in the same league when it comes to technique—I'm not sure where you even got that idea from. They're only similar because they both work by blocking those pain signals before they ever reach the brain, but beyond that, they're totally different beasts.
Look, let's be clear about this: just because you crank up the concentration of the anesthetic doesn't mean an epidural suddenly transforms into a spinal. It just becomes a really solid epidural that lets you comfortably handle surgical procedures without any issues. Plus, you can't forget that the actual epidural catheter used during those procedures isn't even part of the setup for spinal anesthesia, so they're fundamentally different animals.
And, most importantly, the whole "target point" we're aiming for is that epidural space where the catheter needs to be perfectly seated....
Honestly, you couldn't even dream of administering spinal anesthesia into the "lower part of the spinal cord"—that’s just not how it works. The spinal cord actually wraps up much higher up than people realize. You just take the Chirocaine and inject it through a single puncture to get the job done.
So, you're talking about injecting directly into the spinal space—right into the CSF. Honestly, we're talking about a much lower level here where there’s really zero chance of accidentally hitting a nerve or anything like that. It’s all totally separate from the epidural space where you’d be working with an epidural catheter anyway...
What exactly does anyone mean when they say "minor surgery" anyway? I mean, if you’re talking about orthopedic procedures like hip or knee replacements—where they’re basically sawing, cutting, and hammering away at your bones—and almost everyone is under spinal anesthesia, those definitely aren't "minor" in my book.
Honestly, I feel like terms like "general anesthesia" and "total anesthesia" are super vague, and if you ask me, we should probably just stop using them altogether.
When you're doing general anesthesia with muscle relaxants, you’re actually setting an endotracheal tube rather than just a "tube" or "probe." I'm pretty sure that's what you meant, but I figured I should clear that up because in our world, calling it a probe makes people think of a nasogastric tube going straight into the stomach! And yeah, you're totally right about one thing—once those relaxants are in play, you absolutely have to be hooked up to the anesthesia machine.
You know, you can actually pull off real general anesthesia without even touching muscle relaxants, let alone an ET tube... I’ve seen it done just using IV anesthetics, maybe a laryngeal mask, or even the old-school way with a little oxygen through a mask. You don't even strictly need a full anesthesia machine right there, though honestly, it's always a relief to have one within arm's reach just in case things get hairy.
But hey, we've got urbanscout50 hanging out here, so I'm sure he'll weigh in with his take on this too...
