Study Notes
Introduction to Anesthesia
- Anesthetists protect patients from pain and stress during surgery and maintain physiological homeostasis in the perioperative period.
- Their skills are essential in extending practice into intensive care, resuscitation, and non-surgical pain management.
Meaning of Anesthesia
- The term "anesthesia" is derived from Greek, meaning "insensible" or "without feeling."
- Popularized by Oliver Wendell Holmes after the first successful surgical anesthesia demonstration in 1846.
Definition and Effects of General Anesthesia
- General anesthesia results in:
- Loss of awareness.
- No conscious recall of events.
- Lack of muscular response to surgical stimuli, except for respiratory muscles which may respond with increased pulmonary volume.
- Minimal autonomic response to surgical stimulus, though not completely abolished.
- Reversibility of the entire process.
Regional Anesthesia
- Regional or conduction block offers significant safety for patients and minimal effects on cardiovascular and respiratory systems when dosed correctly.
- Applicable for nearly any surgery, especially effective in limb, urologic, and obstetric procedures.
Evolution of Anesthesia
- Over the last five decades, advances in anesthesia have significantly increased patient safety, reducing mortality rates despite more complex surgeries and higher risk patients.
- Early anesthesia practice was dominated by diethyl ether and did not evolve much during its first hundred years.
- Post-World War II, acknowledgment of the anesthetist's crucial role in caring for severely injured patients, along with advances in clinical pharmacology, transformed the field.
- Developments included neuromuscular junction blocking drugs that enhanced anesthetic practice.
Key Historical Figure
- William Thomas Green Morton (1819-1868) was the first to publicly demonstrate inhaled ether as a surgical anesthetic in 1846, marking a pivotal moment in anesthesia history.
