How does anaesthetic work?

Answer 1

Before surgery, an anesthesiologist will meet with you and evaluate your medical condition and formulate an anesthetic plan that is right for you.

During surgery, advanced technology is used to monitor your body's functions, and your anesthesiologist must interpret these sophisticated monitors in order to appropriately diagnose, regulate and treat your body while a personalized, delicate balance of anesthetic medications are administered. In some hospitals, nurse anesthetists may assist the anesthesiologists with the monitoring responsibilities. However, it is the anesthesiologist who is responsible for the interpretation of the monitoring, who make educated medical judgments concerning your responses, and when it is and when it is not appropriate to treat you.

After surgery, your anesthesiologist will reverse the effects of the anesthetic medications you receive, and return you to consciousness once again.

Answer 2

Local anesthesia usually involves the injection of local anesthetic drug with a needle. There are some other ways of delivering local anesthetic drugs - but currently injection is still the most commonly method of delivery.

Local anesthetics work by blocking nerve impulses. At a cellular level this occurs by blocking sodium channels in the nerve membranes. When sodium is blocked in this way, the nerve cannot conduct an impulse and therefore no sensation can be transmitted. Different local anesthetic drugs differ in their side effects, dosages and duration of action.
