The First Scientists to Develop Anaesthesia

The history of anaesthesiology is filled with amazing breakthroughs and incredible discoveries. Since its discovery in the early 1800s, anaesthesia has gone through numerous transformations and changes, slowly but surely becoming the life-saving medical practice, it is today.

The first scientists to develop anaesthesia were a group of dedicated and pioneering individuals who forever changed the course of medical history. Their use of anaesthetics has revolutionized the practice of medicine, allowing doctors and surgeons to carry out their work with less pain and more precision than ever before.

The story of the first scientists to develop anaesthesia begins in 1842, with the work of two Scottish scientists, Dr James Young Simpson and Dr John Snow. Simpson was the first to use ether as an anaesthetic, and it quickly became the standard anaesthetic used in surgery and childbirth. But he was soon joined by Snow, who developed a more effective anaesthetic solution: chloroform.

Before anaesthesia, medical procedures were often extremely painful and lengthy. With the introduction of ether and chloroform, however, doctors were able to perform complicated surgeries and other medical treatments with much less pain and with greater accuracy. It took some time for anaesthesia to be accepted in the medical community. Many doctors were initially sceptical of the use of anaesthesia and argued that it could be dangerous and even deadly. But as the success of Simpson’s and Snow’s methods became more widely known, doctors began to see the potential of anaesthesia, and they began to use it more and more.

Also, among the first scientists to develop anaesthesia were a trio of British physicians – Henry Hill Hickman, Robert Liston, and James Robinson – in the 1820s. All three were highly respected surgeons and pioneers in their fields. Hickman was among the first to develop anaesthesia in its modern form. He was a medical student at the time and had been experimenting with the use of nitrous oxide (laughing gas) to reduce pain during operations. In 1823, Hickman successfully managed to administer the gas to a patient undergoing an amputation, making it the first recorded use of anaesthesia in a medical setting.

Joseph Liston was the first to use ether as an anaesthetic, which he did in 1846 at the University College Hospital in London. He was also the first to perform a limb amputation in under 30 seconds, thanks to his use of ether. Robinson was the last of the trio and the first to discover chloroform as an anaesthetic in 1847. He believed that the gas was superior to ether and proved it by administering it to a patient during a major operation. The trio's work revolutionized the medical field and paved the way for future anesthesiologists. Their discoveries allowed medical practitioners to perform major operations with minimal pain and saved countless lives in the process.

Also ranking among the first scientists to develop anaesthesia were two British scientists, Sir Humphry Davy and James Simpson. They worked separately, but together, they revolutionized the practice of surgery, making it a much less painful experience. Sir Humphry Davy was a renowned chemist who was largely responsible for developing the first anaesthetic, nitrous oxide. This gas has been known to alleviate pain since the early 1800s when it was used in laughing gas parties. Davy went a step further, experimenting on himself with nitrous oxide and concluding that it was effective when inhaled in large amounts. He published his findings in a paper, "On the Inhalation of the Nitrous Oxide", which was the first scientific work on the subject.

James Simpson was a Scottish obstetrician and gynaecologist who was instrumental in the development of chloroform as an anaesthetic. He had received a chemical sample of chloroform from a manufacturer and, after experimenting with it, concluded that it was a safe and effective anaesthetic. He presented his discovery to the Edinburgh Obstetrical Society in 1847, where it was met with great enthusiasm. Together, Davy and Simpson had unlocked a new realm of possibilities in the medical field, allowing for painless surgery and treatments to become a reality. In the years that followed, anaesthetics have become even more advanced, and today, anaesthesia is a common and widely accepted practice in the medical field.

The scholars' achievements made painless surgery a reality, and for that, we owe them both a great debt of gratitude. They also paved the way for modern medicine. By the early 1900s, anaesthesia had become an accepted medical practice, and its use had spread throughout the world. Today, anaesthesia is an important part of medical care -it has saved countless lives. We owe gratitude to the first scientists to develop anaesthesia, who made it possible for us to enjoy a more comfortable and safer medical experience.

University Research Cells Visualized in Real Time

University Research Cells Visualized in Real Time

In a study recently published in the Journal of Extracellular Vesicles, researchers from Kanazawa University use high-speed microscopy to capture the dynamics of nanosized sacs released from cells. Small extracellular vesicles (sEVs) are tiny sacs released by cells to deliver chemical messengers to other cells. Since sEVs are compatible with biological tissue they are being investigated as carriers for nanodrugs. However, the impact of physiological stress—such as changes in temperature—on the structure of sEVs is obscure. A research team led by Richard Wong and Keesiang Lim at Kanazawa University has now used an advanced form of microscopy to elucidate these changes in real time.

The temperature, acid, and salt levels in our bodies can fluctuate with factors such as disease. Thus, research on sEVs for drug development requires a deeper understanding of how stressful environments affect the vesicles' structure. For their study, the team first isolated sEVs from cells. Next, using a technique known as high-speed atomic force microscopy (HS-AFM) the structure of sEVs was revealed to be either spherical or ellipsoidal in shape. HS-AFM also enabled the researchers to accurately measure the sizes of sEVs without rupturing or damaging the vesicular membranes.

The effect of varying temperatures on sEVs was the first parameter assessed. At temperatures higher than normal (37°C) body temperature the vesicles showed deformations in shape coupled with a loss of elasticity of their membranes. On the other hand, sEVs in cold conditions (4°C) had a reduced ability to release any internal material effectively.

The researchers then studied the effects of pH (acid levels) on sEVs. The physiological pH of the bloodstream is 7.4. A pH less than 7 indicates acidic conditions and anything more than that is termed alkaline. The sEVs seemed to maintain their shape in acidic conditions (pH 4) but in alkaline conditions (pH 10) they were deformed. However, at a pH of 4 the sEVs were smaller in size suggesting their internal contents had been lost.

Now, salt levels (known as osmotic pressure) at a concentration of 0.15 M are healthy. However, changes in osmotic pressure can have detrimental effects on cells. As conditions were gradually changed it was found that the spherical nature of sEVs decreased at high salt concentrations (1.8 M) but seemed to remain intact at low concentrations (0 M). After a while, vesicles in high osmotic conditions showed ruptured membranes.

An understanding of these dynamics is imperative to formulating sEVs as pharmaceutical aids in different disease conditions. This study established HS-AFM as a useful tool to depict changes in sEVs under various physiological conditions in real time. "In summary, our study demonstrates the feasibility of HS-AFM for structural characterization and assessment of nanoparticles," concludes the team.

Small extracellular vesicles (sEVs): sEVs are sacs containing chemicals such as proteins, DNA, or metabolites released by cells. Usually playing the role of messengers, sEVs then deliver these chemicals to neighboring or distant cells. Hence, their shape, size, and elasticity are important for sEVs to function properly. For example, sEVs with reduced membrane elasticity might not be able to release their contents effectively.

sEVs are typically less than 200 nm in size and ferry around very small molecules. They are, therefore, under investigation for their potential role in delivering nanosized drugs/vaccines or chemicals used for diagnosis. The physical properties of sEVs in under varying physiological stress are, thus, important for understanding their behavior in different tissues and disease conditions.

High-speed atomic force microscopy (HS-AFM): Traditional AFM is a form of microscopy that utilizes a pointed lever grazing on the surface of molecules to depict their topography. As the lever moves about, it transmits signals that help create an image of the molecule's structure. However, the rate at which signals are emitted in AFM are too low to capture any dynamic changes. HS-AFM, on the other hand, enables a faster scanning of molecules such that images can be acquired in real-time. Even minor changes to a molecule's structure can be accurately captured.
