Study Notes

Introduction of Anesthesia

The term "anesthesia" was first defined in 1721 as "defect of sensation."
Oliver Wendell Holmes coined the term "anesthesia" in 1846 to describe the sleeplike state induced during surgery.
The history of anesthesia dates back to ancient civilizations where substances like opium poppy, coca leaves, mandrake root, and alcohol were used for pain relief during surgery.
Ancient Egyptians used a combination of opium poppy (containing morphine) and hyoscyamus (containing scopolamine) for anesthesia.

Inhalation Anesthesia

Ether, prepared in 1540 by Valerius Cordus, was used for anesthesia in 1842 by Crawford W. Long and William Clark but not publicized.
William Morton successfully demonstrated the use of ether for surgical anesthesia in Boston on October 16, 1846.
Chloroform, independently prepared in 1831 by Von Leibig, Guthrie, and Souberian, was first used for anesthesia in 1847 by Holmes Coote.
Professor James Simpson introduced chloroform for pain relief during childbirth in 1847.
Nitrous oxide (N2O), produced by Joseph Priestly in 1772, was first recognized for its analgesic properties by Humphrey Davy in 1800.
Horace Wells first demonstrated the use of nitrous oxide for anesthesia in humans in 1844.

Intravenous Anesthesia (IVA)

The invention of the hypodermic syringe and needle by Alexander Wood in 1855 paved the way for intravenous anesthesia.
Pierre Cyprien Ore, a pioneer of IVA, introduced chloral hydrate as an anesthetic in 1872.
Barbiturates were synthesized in 1903 and used for inducing anesthesia.
Ketamine was synthesized in 1965 by Stevens and first used clinically in 1970.
Propofol, first released in 1986, has become the most popular agent for intravenous induction worldwide.

Evolution of the Specialty

The independent medical specialty of anesthesiology emerged in the early 20th century.

British Origins

Ether anesthesia was quickly adopted in England.
John Snow is considered the father of the anesthesia specialty.
In 1893, the first organization for physician specialists in anesthesia, "The Society of Anesthetists," was established in England.

American Origins

Few physicians specialized in anesthesia in the United States by 1900.
The first organization of physician anesthetists, "The Long Island Society of Anesthetists," was formed in 1905.

History of Anesthesia in Saudi Arabia

Dr. Mohamed Ishaq Al Khawashki addressed the shortage of anesthetists in Saudi Arabia by advocating for the establishment of technical institutes to train anesthesia technicians.
Professor Mohammed Abdullah Seraj, known as the "father of anesthesia in the Kingdom of Saudi Arabia," established the first anesthesia department at King Abdul-Aziz University Hospital, King Saud University.

What is Anesthesiology?

Anesthesiology is the practice of medicine focused on pain relief and the total care of surgical patients before, during, and after surgery.
Anesthesiologists are physicians who complete six years of medical school followed by a four-year anesthesiology residency training program.
Anesthesia technologists work under the direction of anesthesia care providers as essential members of the anesthesia care team.

Role of an Anesthesiologist

Anesthesiologists are perioperative physicians who provide medical care to patients before, during, and after surgery.
This includes evaluating the patient preoperatively, consulting with the surgical team, providing pain control, supporting life functions intraoperatively, and supervising postoperative care.

Anesthesiologist in the Operating Room

Anesthesiologists continuously monitor and control the patient's vital functions such as heart rate, rhythm, breathing, blood pressure, body temperature, and fluid balance during surgery.
They diagnose and treat any medical problems that may arise during surgery or recovery.

Post Anesthesia Care Unit (PACU)

Patients are transferred to the PACU after surgery to allow them to fully recover from anesthesia.
Skilled nursing personnel observe and stabilize the patient, transferring them to a regular room or home once suitable.

Anesthesiologists Outside the Operating Room

Provide sedation and anesthesia outside the operating room for procedures such as magnetic resonance imaging and cardiac catheterization.
Share in cardiopulmonary resuscitation efforts.
Manage the care of both mother and baby during childbirth.
Anesthesiologists are also involved in pain management, diagnosing and treating acute and chronic pain issues.

Definition and History of Anesthesia

The term "anesthesia" was defined as "defect of sensation" in Bailey's Universal Etymological English Dictionary in 1721.
Oliver Wendell Holmes used the current meaning of "anesthesia" in 1846, referring to a sleeplike state that allows for painless surgery.
Ancient civilizations used opium poppy, coca leaves, mandrake root, and alcohol to allow surgeons to operate.
Ancient Egyptians used a combination of opium poppy (containing morphine) and hyoscyamus (containing scopolamine).

Anesthesiologists participate in cardiopulmonary resuscitation (CPR).
Anesthesiologists manage the care of both the mother and the baby during childbirth.
Anesthesiologists are also involved in pain management, diagnosing and treating acute and chronic pain problems.

Anesthesia Definition & History

The term "anesthesia" was defined in 1721 as "defect of sensation" by Bailey's Universal Etymological English Dictionary.
Oliver Wendell Holmes used the current meaning of "anesthesia" in 1846, referring to a sleeplike state that allows for painless surgery.

Early Anesthesia Techniques

Ancient civilizations used opium poppy, coca leaves, mandrake root, and alcohol for surgical procedures.
Ancient Egyptians combined opium poppy (containing morphine) and hyoscyamus (containing scopolamine).

Ether

Ether was first prepared in 1540 by Valerius Cordus.
Crawford W. Long and William Clark used ether on patients in 1842 but did not publicize their discovery.
The first successful surgical anesthesia using ether was performed in Boston on October 16, 1846.

Chloroform

Chloroform was independently prepared in 1831 by Von Leibig, Guthrie, and Souberian.
It was first used in 1847 by Holmes Coots.
Professor James Simpson introduced chloroform to clinical practice for relieving labor pain.

Nitrous Oxide (N2O)

Nitrous oxide was produced by Joseph Priestly in 1772.
Humphrey Davy first noted its analgesic properties in 1800.
Horace Wells was the first to use nitrous oxide for human anesthesia in 1844.

Intravenous Anesthesia

The invention of the hypodermic syringe and needle in 1855 allowed for intravenous anesthesia.
Pierre Cyprien Ore pioneered Intravenous Anesthesia (IVA) in 1872 using chloral hydrate.
Barbiturates, synthesized in 1903, were used for anesthesia induction.

Role of the Anesthesiologist

Anesthesiologists are perioperative physicians responsible for providing comprehensive patient care before, during, and after surgery.
This includes evaluating patients preoperatively, consulting with the surgical team, providing pain control, supporting life functions during surgery, and supervising postoperative care.

Anesthesia Care Responsibilities

Anesthesiologists continually assess patients and monitor vital functions (heart rate, rhythm, breathing, blood pressure, body temperature, fluid balance).
They diagnose and treat medical problems that may arise during surgery or recovery.
They control pain and levels of unconsciousness.

Postoperative Care

After surgery, patients are transferred to a recovery room under the care of skilled nursing personnel.
Once they recover from anesthesia, they are discharged to a regular room or home.

Other Anesthesiologist Roles

Anesthesiologists provide sedation and anesthesia outside the operating room, for procedures like magnetic resonance imaging, cardiac catheterization, etc.
