Anesthesia Lab (Beer's Law)

by Gerald Maxwell


The materials necessary are as follows: Computer, so that the information and data can be logged to be used for later: Colorimeter, so that the solutes can be tested for the amount of light that passes through them: Cuvettes, so that you have something to put the solute in and measure it in the colorimeter.


Set up logger pro on your computer and set up the colorimeter.

Then fill the cuvettes with the solute so that they can be measured.

Background Information

Attempts at producing a state of general anesthesia can be traced throughout recorded history in the writings of the ancient Sumerians, Babylonians, Assyrians, Egyptians, Greeks, Romans, Indians, and Chinese. During theMiddle Ages, which correspond roughly to what is sometimes referred to as the Islamic Golden Age, scientists and other scholars made significant advances in science and medicine in the Muslim world and Eastern world, while their European counterparts also made important advances.

The Renaissance saw significant advances in anatomy and surgical technique. However, despite all this progress, surgery remained a treatment of last resort. Largely because of the associated pain, many patients with surgical disorders chose certain death rather than undergo surgery. Although there has been a great deal of debate as to who deserves the most credit for the discovery of general anesthesia, it is generally agreed that certain scientific discoveries in the late 18th and early 19th centuries were critical to the eventual introduction and development of modern anesthetic techniques.

Two "quantum leaps" occurred in the late 19th century, which together allowed the transition to modern surgery. An appreciation of the germ theory of disease led rapidly to the development and application of antiseptictechniques in surgery. Antisepsis, which soon gave way to asepsis, reduced the overall morbidity and mortality of surgery to a far more acceptable rate than in previous eras. Concurrent with these developments were the significant advances in pharmacology and physiology which led to the development of general anesthesia and the control of pain.

In the 20th century, the safety and efficacy of general anesthesia was improved by the routine use of tracheal intubation and other advanced airway management techniques. Significant advances in monitoring and newanesthetic agents with improved pharmacokinetic and pharmacodynamic characteristics also contributed to this trend. Finally, standardized training programs for anesthesiologists and nurse anesthetists emerged during this period. And, of course, the increased application of economic and business administration principles to health care in the late 20th and early 21st centuries inevitably led to the introduction of management practices such as transfer pricing to improve the efficiency of anesthetists.[1]


We found that in the experiment Aunt Elda had been given too much anesthesia and went into a coma because the does that she was given was over 40%, which is a lethal amount. She also unfortunately passed away because of that event. This was discovered by comparing the amount of light that went through Aunt Elda's mystery solute and the rest of the solutes.

Creating a 20% solution (in case you need an anesthetic for something)

step 1. have 10 mL of water handy

step 2. measure 2 mL of anesthesia

step 3. combine the anesthesia and water

step 4. use 20% anesthetic as you please
