Is general anesthesia caused by a gas or an injection?

Is general anesthesia caused by a gas or an injection?

Either or both: General anesthesia is a state of unconsciousness and lack of reaction to painful stimuli. It can be brought on by intravenous medications such as propofol, sodium pentothal, and ketamine. Anesthesia gases (desflurane, sevoflurane) will also produce general anesthesia. Often you will receive a combination of both during surgery. ...Read more

Is using laughing gas considered general anesthesia?

Is using laughing gas considered general anesthesia?

Usually, yes: "laughing gas" is the slang term used sometimes for a gas called nitrous oxide. It is a weak anesthetic gas that is not usually enough to produce general anesthesia by itself. For surgery, it is used in combination with other gases such as sevoflurane or desflurane. In the dentist's office, it is sometimes given to supplement the local anesthesia that the dentist will use to numb the tooth. ...Read more

What do patients remember if under general anesthesia or laughing gas?

Sister is 15. She got general anesthesia instead of local anesthetic during an upper GI endoscopy. It was 9 am and she got it through gas and iv. Why?

Sister is 15. She got general anesthesia instead of local anesthetic during an upper GI endoscopy. It was 9 am and she got it through gas and iv. Why?

Sedation: Most if not all patients require some sedation for endoscopies. Usually this is accomplished by medication through an iv. Some patients, usually children, do not want an IV while they are awake, so an anesthesiologist can use gas to sedate the patient and then place an iv. The rest of the sedation will be done via the iv. Local anesthetic alone is not usually effective. ...Read more

Do you know if there are similarities between unconsciousness caused by trauma, and unconsciousness by general anesthesia?

Do you know if there are similarities between unconsciousness caused by trauma, and unconsciousness by general anesthesia?

Not likely: General anesthesia is a reversible condition. Unconsciousness from trauma often is temporary, but the duration is unknown because the mechanism is different. Trauma causes damage to nerve transmission from sweeping and direct cell damage. Anesthetic drug effects dissipate over time. ...Read more

I was on shoulder stabilisation 2 months ago. Since i itch all over body+rash on both shoulders. Is it possible that its caused by general anesthesia?

Doubt it: I assume you had general anesthesia 2 months ago for the surgical procedure. I can't imagine how general anesthesia could cause a rash that persists for 2 months. (some medications given during anesthesia may cause a rash that lasts for a few minutes. These are similar to a mild allergic reaction confined to the skin and resolve quickly.). ...Read more

Can eye floaters be caused by general anesthesia or swimming goggles?

Can eye floaters be caused by general anesthesia or swimming goggles?

No: Your floaters are inside your eyes' vitreous cavity and occur as a result of aging of the eye. Normally these gradually develop, but occasionally they can increase suddenly, usually associated with light flashes & a noticeable change in the quality of your vision. If this occurs, a dilated eye examination is important to rule out other problems causing the floaters, such as a tear in the retina. ...Read more
