Answer:
Propofol is one of the most commonly used intravenous drugs employed to induce and maintain general anesthesia. It can also be used for sedation during procedures or in the ICU. Like the other agents mentioned above, it renders patients unconscious without producing pain relief.
Answer:
Local anesthesia refers to using a drug called an anesthetic to temporarily numb a small area of your body. Your doctor might use a local anesthetic before doing a minor procedure, such as a skin biopsy. You might also receive local anesthesia before a dental procedure, such as a tooth extraction. Unlike general anesthesia, local anesthesia doesn’t make you fall asleep.
Explanation:
Local anesthetics are generally safe and usually don’t cause any side effects, aside from some tingling as it wears off. However, if you’re given too much, or the injection goes into a vein instead of tissue, you might have more side effects, such as:
ringing in your ears
dizziness
numbness
twitching
a metallic taste in your mouth
In extremely rare cases involving very high doses, anesthesia may cause:
seizures
low blood pressure
slowed heart rate
breathing problems
It’s also possible to have an allergic reaction to an anesthetic, but this is rare. A 2011 studyTrusted Source estimates that only about 1 percent of people are allergic to local anesthetics. In addition, most allergic reactions to local anesthetics are due to a preservative in the anesthetic, rather than the drug itself
