SIGNIFICANT PEOPLE

Charles F. Kettering

Charles F. Kettering invented the battery powered starting engine.  It was first installed in the 1912 Cadillac, and helped win the future for the gasoline engine.  When automobile drivers noticed “knocking” he suspected that the source of the knock was not in the engine, but it was in the fuel.  He was determined to find an additive to gasoline that could lessen knocking.  However, he moved from his Dayton Engineering Laboratory to General Motors, and turned the research over to Tom Midgley. 

 Thomas Midgley

Thomas Midgley invented the bouncing pin test engine so that the knock within the engine could be determined by ear.   He also invented an optical gas engine indicator to look at and record the shape of the pressure wave inside the engine’s cylinder which is a result from the combustion of fuel and air.  Anti-knock fuel for airplanes which all had internal combustion engines, became important for the United States during World War I.

Russell Marker 

Russell Marker created the octane rating system that is used to pump gas.  He discovered the difference between heptane and isooctane and how heptane causes a lot of knocking and isooctane prevents knocking.  He concluded that the fact that isooctane has eight carbons and heptane has seven is the difference in the characteristics of the molecules, and just had to do with odd versus even numbers of carbon atoms.

Eugene Houdry

Eugene Houdry invented a catalytic “reforming”” of gasoline to produce a higher octane gasoline which was used in aviation fuel.   It blended refined gasoline, which had an octane number around 70, with pure isooctane and isopentane to increase the octane number.  The reformed gasoline enabled aviation fuel to reach 100 octane with half the additives needed for other gasolines, and enabled military aircraft in World War II to be supplied with high octane gas.

Allergic reactions to Novocaine happen by a case to case basis, and depend on where the drug is injected. Due to the sensitivity of the location, Novocaine injected in the spinal region can respond more adversely then oral injections for dental procedures.

The FDA cautions patients with other allergies or sensitivities to drugs to be careful when being prescribed Novocaine injections. Patients with heart problems or conditions need to use the most caution when receiving Novocaine. Also, any patient already taking a sulfonamide drug should notify the physician because the aminobenzoic acid in the Novocaine molecule stops the action of the sulfonamide.

Possible Side Effects: Spinal Injection

• systemic toxicity– symptoms include: dizziness, tremors, blurred vision, convulsions and nervousness
• hypotension
• post-spinal headache
• spinal nerve paralysis
• palsies
• respiratory problems
• nausea and vomiting

There is no specific treatment for systemic toxicity.

The modernization of anesthesia, specifically lidocaine, has become more hypoallergenic and eliminates some of the possible reactions presented by Novocaine.

As history repeats itself and scientists continuously attempt to find and create new and more effective molecules, Novocaine took the backseat in the anesthetic world when lidocaine entered the scene in the mid-1940s. Just as Novocaine’s structure mimicked the cocaine, lidocaine’s structure relates to the Novocaine.

Pop Culture makes references to Novocaine all the time, especially musicians in songs lamenting heartache and wanting to numb the pain.

Green Day perfected making Novocaine a synonymous for numbing the pain in their song Give Me Novocaine:

Drain the pressure from the swelling,
The sensations overwhelming,
Give me a long kiss goodnight and everything will be alright
Tell me that I won’t feel a thing
So give me Novacaine

Cocaine may not had been the safest anesthetic choice, but it did however make for a fabulous numbing device. When chemist set out to discover better choices, they sought synthesize a mimic of cocaine with lower toxicity and less dangerous side effects. The result…Procaine!

In 1905, German chemist Alfred Einhorn synthesized the exact combination of eliminating the bad and mimicking the good from cocaine into his new compound Procaine (Novocaine). Einhorn’s revolutionary discovery, however, sat in his lab in Germany, leaving many bewildered dentist without the new Novocaine to ease the pain.

Luckily, a curious dentist, Dr. Mendel Nevin was traveling through Europe giving lectures in his field. After a visit to Dr. Einhorn’s lab, Dr. Nevin retrieved some of Einhorn’s procaine. Dr. Nevin then began to make his own procaine back in New York. By 1911, the popularity of the drug became big enough that Nevin had serendipitously started the Novocal Chemical Manufacturing Inc.

The progression of history and discovery led to Novocaine’s birth which only further propelled the anesthetic market.

The medical practice of anesthesia and the quest to alleviate a patient’s pain transcends back centuries with different civilizations developing their own unique ways to dull the pain. In modern society, however, the greatest advancement in anesthetics was the discovery of cocaine. Using cocaine as local anesthesia paved the way for the development of Novocaine, which was a safer alternative to cocaine.

Although cocaine was used among the Incas and other societies with a strong cocoa leaf population, it was not until the invention of the hypodermic syringe that cocaine infiltrated mainstream medical society. Cocaine proved to be a solid numbing local anesthetic that was used in mostly oral and eye surgeries.

 Eventually, however, the strong toxicity and addictive nature of cocaine proved dangerous in the field and chemists looked towards making a new and better compound.
