Chapter 12 SLO 4.1 Flashcards
Adjunct anaesthetics
Drugs used in combination with anaesthetic drugs to control the adverse effects of anaesthetics or to help maintain the anaesthetic state in the patient (See balanced anaesthesia). (p. 196)
Anaesthesia
The loss of the ability to feel pain, resulting from the administration of an anaesthetic drug. (p. 196)
Anaesthetics
Drugs that depress the central nervous system (CNS) or peripheral nerves to produce decreased sensation, loss of sensation, or muscle relaxation. (p. 196)
Balanced anaesthesia
The practice of using combinations of different classes of drugs rather than a single drug to produce anaesthesia. (p. 196)
General anaesthesia
A drug-induced state in which CNS nerve impulses are altered to reduce pain and other sensations throughout the entire body. It normally involves complete loss of consciousness and depression of normal respiratory drive. (p. 196)
Local anaesthesia
A drug-induced state in which peripheral or spinal nerve impulses are altered to reduce or eliminate pain and other sensations in tissues innervated by these
nerves. (p. 196)
Malignant hyperthermia
A genetically linked, major adverse reaction to general anaesthesia characterized by a rapid rise in body temperature as well as tachycardia, tachypnea, and sweating. (p. 198)
Overton–Meyer theory
A theory that describes the relationship between the lipid solubility of anaesthetic drugs and their potency. (p. 197)
Procedural sedation
A milder form of general anaesthesia that causes partial or complete loss of consciousness but does not generally reduce normal respiratory drive (formerly referred to as conscious sedation or moderate sedation). (p. 200)
Spinal anaesthesia
Local anaesthesia induced by injection of an anaesthetic drug near the spinal cord to anaesthetize nerves that are distal to the site of injection (also called intraspinal anaesthesia). (p. 201)
