DAANCE- Module 3-
Anesthetic Drugs &
Techniques
Brevital (Sodium Methohexital) - ANSWER Primary anesthetic agent introduced in the
1960's.
Balanced
... [Show More] Anesthesia - ANSWER Use of several agents together
Basic Requisites of an Anesthetic - ANSWER Lack of toxicity, non-flammable, nonaddictive, minimal allergenicity.
Analgesia - ANSWER Given to feel no pain (ex: Fentanyl and Local)
Amnesia - ANSWER Benzodiazepines (ex: Versed)
Relaxation & Immobility - ANSWER Versed, Propofol (Diprivan), Brevital
(Methohexital), Ketamine
Loss of Consciousness (Hypnosis) - ANSWER Propofol & Brevital
Wakefulness System - ANSWER Core of brainstem, neurons to cerebrum. When a
sleep inducing drug is introduced it interrupts transmission.
Anxiolytic (Anxiety Reducing) Meds - ANSWER Diazepam or Midazolam
Relay Center - ANSWER Sensory neurons that sense pain pass through this.
Homeostasis (Homeostatic State) - ANSWER Normal state in which there is minimal
variation in respiration and circulation.
Pharmacokinetics - ANSWER The effects that the body has on drugs.
Pharmacodynamics - ANSWER The effects that the drug has on various body systems.
Rapid Redistribution - ANSWER Short acting drug only remain attached to the receptor
sites for a short time and then move to the other tissues.
PO (per os) - ANSWER Through the mouth.
(Delayed onset, unpredictable effects, patient compliance, not good when pt in
nauseated)
Subcutaneous (SQ) - ANSWER Beneath the Skin
(Absorption is somewhat delayed compared to IM or IV)
Intramuscular (IM) - ANSWER In the muscle
(Unpredictable onset of drug effect, cannot titrate the dose)
Intravenous (IV) - ANSWER In the vein
Inhalation Route - ANSWER Inhaled
(Very rapid absorption and titration)
4 Levels of Continuum - ANSWER Minimal Sedation, Moderate Sedation, Deep
Sedation (Analgesia), and General Anesthesia
Minimal Sedation (Anxiolysis) - ANSWER Normal response to verbal stimulation,
cardiovascular function unaffected.
Moderate Sedation (Conscious Sedation) - ANSWER Normal response to verbal or
light tactile stimulation with cardiovascular function usually maintained.
Deep Sedation (Analgesia) - ANSWER Not easily aroused but has purposeful response
after repeated or painful stimulation.
General Anesthesia - ANSWER Not a rousable even with painful stimulation.
Diffusion hypoxia - ANSWER Nitrous Oxide rapidly moves from the blood to the alveoli
of the lungs and displaces other gases, including oxygen.
Hypoxia - ANSWER Low levels of oxygen in the bodies tissues.
Hypercarbia - ANSWER An increased level of carbon dioxide.
Anxiolytic - ANSWER Triazolam, Diazepam, Modazolam [Show Less]
