Understanding anesthetics

Anesthesia is an induced, temporary state usually used to prevent pain

Anesthetics are used by dentists and hospitals to prevent patients from feeling pain. It is most commonly used in hospitals for surgery and in dentists for different operations. Dentists may use laughing gas as an anesthetic which has a few side effects including laughing.

Types of anesthetics

There are two types of anesthetics, general and local. Local are used by dentists and for small procedures and are usually just applied to one part of the body and the patient usually is kept awake. General anesthetics are used in bigger operations and put the patient to sleep completely.

How it works

Anesthetics work by preventing nerves from carrying pain signals to the brain. They prevent sodium ions from going from one nerve cell to the other. The complete science of anesthetics is not entirely understood at this point.

Nitrous Oxide

One of the best general anesthetics is nitrous oxide which was used back in the 18th century and still today. English Clergyman Joseph Priestly discovered this anesthetic in 1793. Nitrous oxide is a colorless and almost odor less gas. People now refer to nitrous oxide as laughing gas which is used mainly in dentistrys.

How to make a % solution

We had the 60% solution so we put in 60 ml of the green liquid and 40 ml of water. If you had say 30% you would put in 30 ml of green liquid and 70 ml of water.

Lab observations

We noticed throughout the lab that the more green liquid in the % solution the more absorbance. This was true throughout the entire lab.


Aunt Elda's anesthesia was too strong so she would have died.

This caused her death because the percent composition was too high.

Beer's law let us know that the anesthesia was too high and that she would die.
