Inhalational Anesthetics: Overview

Inhalational Anesthetics: Overview

Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

2° Amines to N-Nitrosamines: Reaction with NaNO2

2° Amines to N-Nitrosamines: Reaction with NaNO₂

Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO₂ Overview

Nitrous acid and nitric acids are two types of acids containing nitrogen, among which nitrous acid is weaker than nitric acid. Nitrous acid with a pKa value of 3.37 ionizes in water to give a nitrite ion and the hydronium ion.
The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...

Drug Delivery: Enteral Route

Drug Delivery: Enteral Route

The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.
Drugs in...

Hyperpnea and Hyperventilation

Hyperpnea and Hyperventilation

Hyperventilation refers to a higher-than-normal rate and depth of breathing, often associated with anxiety attacks. This excessive breathing surpasses the body's need to expel CO2, leading to a condition known as hypocapnia - an unusually low level of carbon dioxide in the blood. Hypocapnia can constrict cerebral blood vessels, reducing blood flow to the brain, which may result in dizziness or fainting. Early signs include tingling and muscle spasms in the hands and face, caused by falling...

Stimulants

Stimulants

Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Area of Science:

Anesthesiology
Physiology
History of Medicine

Background:

Historical beliefs regarding nitrous oxide (N2O) suggested it could sustain life similarly to oxygen.
Prominent historical figures, including Humphry Davy, Gardner Q. Colton, and George W. Crile, contributed to this life-threatening misapprehension.
Simultaneously, the deprivation of oxygen was erroneously considered a necessary condition for effective nitrous oxide anesthesia.

Discussion:

The persistent misconception of nitrous oxide as an oxygen substitute highlights a critical gap in early physiological understanding.
The influence of respected authorities propagated dangerous, albeit unintentional, misinformation regarding anesthetic gases.
The dual misconception—N2O as life-supporting and oxygen deprivation as requisite—created a hazardous environment for patients undergoing anesthesia.

Key Insights:

Nitrous oxide's physiological role was fundamentally misunderstood for a significant period.
Historical authorities played a crucial role in disseminating inaccurate information about anesthetic gases.
The practice of oxygen deprivation during N2O anesthesia posed direct risks to patient safety.

Outlook:

Revisiting historical misconceptions of anesthetic gases is vital for appreciating advancements in modern anesthesiology.
Understanding past errors informs current safety protocols and research directions in respiratory physiology.
Further historical analysis can illuminate the evolution of scientific understanding and its impact on medical practice.
