Anesthesia...How does it put you to sleep?
General anesthesia have different components that all work together to maintain people risk-free and comfortable for surgery.
The first part is "induction", which is the going sour to sleep part. We use a fast-acting i.v. drug to do that. (Usually propofol or pentothal) This drug works on the brain to do unconsciousness, and it also take away your ability ot breathe.
Most of the time, we later give a paralytic agent that blocks the nouns of signals between the nerve and muscles. This let us get a breathing tube surrounded by, so that we can put the patient on a ventilator and deliver anesthetic gas.
The gases we use (desflurane, sevoflurane, isoflurane - relatives of ether) also work on the brain. They preserve people asleep, and provide a small amount of muscle relaxation and discomfort relief. We might mix contained by nitrous oxide to make the gas we use "stir farther". (It's a weak anesthetic, but let us use less of the other stuff)
During the procedure, we usually bestow a sedative call midazolam (Versed) to aid in amnesia, and narcotic discomfort medicines (we enjoy a bunch to choose from, but it's usually fentanyl, morphine, and/or dilaudid). Sometimes we use a short acting narcotic and a long acting narcotic, so there's some pain medication on board when the long-suffering wakes up.
We may or may not verbs the paralytic, depending on the case.
Medicine to prevent an upset stomach is also frequently administered.
At the expire, we may need to reverse the paralysis. We turn sour the gas and give pure oxygen to back get rid of the residual anesthetic gas. We carry him/her breathing again, and take out the breathing tube. Then it's bad to recovery.
There are abundantly of "sometimes" and "usually"'s in this explanation, because anesthesiology is more complex than most nation realize (that's why we spend years learning how to do it), and every casing is different.
Hope that helps.
"The aim of anesthesia is to produce a state whereby patients surface no pain, own no recall, are comatose and do not move while surgery is occurring," says U of T anesthesia professor Dr. Isabella Devito. "To create these effects, anesthesiologists administer a broad array of narcotics, inhaled or injected agents and muscle relaxants, normally in combination."
General anesthesia, within very simplistic expressions, implies that medication are used that affect the brain in a means of access that causes blackout. As a result, the patient become unaware of stimulation and headache and does not remember anything (amnesia). Some of the medication used are the same or similar to medication that are used in sedation, but recurrently at a higher dose.
And, if administered correctly, you can wake up within the middle of surgery... with tubes contained by your throat and nose resembling I did - not pleasant at all.
Anesthesia make the control system of your brain inactive
Usually a drug name Pavulon. It blocks nerve impulse to muscles thereby causing short-term paralysis. Morphine or Dilaudid given on top of that to block cramp signals from the brain by attaching to opiate receptors. Then Versed to keep you from remembering what you hear during surgery. That's what we other used in the OR!
works on the parts of the brain that put you to sleep!!
General anesthesia (the one that puts you to sleep) affects the brain cell, which causes you to lose consciousness.

a chemical...called anesthesia,puts you to sleep by running through your blood stream and right into your brain wich consequently triggers the part of the brain that say go to sleep.
One entity that makes medication interesting and stimulating is that it's very much more complicated than most folks think. Different drugs achievement in different ways on different parts of the brain/body to induce anesthesia. There only isn't a simple explanation, but if you're being put beneath soon your anesthesthiologist will plan what he feels is best for you and can bestow you a "Sleep for Dummies" version of his plan.
