Intro to Anesthesia - Pharm

Anesthesia

Loss of sensation; derived from Greek meaning "without feeling" or "insensibility."

General Anesthesia

Reversible state of unconsciousness, immobility, muscle relaxation, and loss of sensation throughout the entire body.

Surgical Anesthesia

Specific stage of general anesthesia allowing surgery without patient pain or movement.

Analgesia

Loss of sensation of pain.

Sedation

Drug-induced CNS depression and drowsiness, with varying levels of awareness.

Tranquilization

Drug-induced calm state with reduced anxiety, but no analgesic effects.

Hypnosis

Drug-induced sleeplike state where the patient can be roused with sufficient stimuli.

Narcosis

Drug-induced sleep from which the patient is not easily aroused, often associated with narcotics.

Local Anesthesia

Loss of sensation in a small area of the body via local anesthetic agent.

Topical Anesthesia

Loss of sensation in a localized area through direct application of local anesthetics.

Regional Anesthesia

Loss of sensation in a limited area by administering local anesthetic near sensory nerves.

Balanced Anesthesia

Technique using multiple drugs in smaller quantities to maximize benefits and minimize adverse effects.

Veterinary Technician/Nurse

Responsible for preparation, operation, maintenance of equipment, administration of anesthetics, intubation, and patient monitoring.

Therapeutic Index

Range between the effective dose and toxic dose of anesthetic agents; narrow in most anesthetics.

Monitoring Vital Signs

Critical for detecting changes in cardiovascular and pulmonary function during anesthesia.

Anesthetist's Role

Requires rapid interpretation of visual, tactile, and auditory information to manage patient care effectively.

Legal Implications

Serious accidents during anesthesia can lead to legal action from clients against veterinary staff.

Importance of Standards

Maintaining high standards and accurate medical records is crucial in anesthetic practice.
