DAANCE Module 3: Anesthetic Drugs and Techniques
Brevital (Sodium Methohexital) - ✔✔ultra short acting barbiturate.
cardio effects : decrease in BP with a compensatory increase in HR.
side effects: injection pain, phlebitis, coughing, hiccups, laryngospasm, twitching and tremors.
Balanced Anesthesia - ✔✔several different drugs are combined that have effects that complement each
other.
Basic Requisites of an Anesthetic - ✔✔Lack of toxicity, non-flammable, non-addictive, minimal
allergenicity.
Analgesia - ✔✔Given to feel no pain (ex: Fentanyl and Local); be pain free throughout the procedure
Amnesia - ✔✔patients do not want to have any memory of what occurred.
Benzodiazepines (ex: Versed) or valium
Relaxation & Immobility - ✔✔unwanted movement to be minimized.
Versed, Propofol (Diprivan), Brevital (Methohexital), Ketamine
Loss of Consciousness (Hypnosis) - ✔✔Propofol & Brevital
Wakefulness System - ✔✔Core of brainstem, neurons to cerebrum. When a sleep inducing drug is
introduced it interrupts transmission.
- propofol & brevital.
, Produced by a complex interaction between multiple neurotransmitter systems arising in the brainstem
and ascending through the midbrain, hypothalamus, thalamus and basal forebrain. The posterior
hypothalamus plays a key role in the maintenance of the cortical activation that underlies wakefulness.
Anxiolytic (Anxiety Reducing) Meds - ✔✔Diazepam or Midazolam
Relay Center - ✔✔Sensory neurons that sense pain pass through this.
- ketamine
The thalamus is the relay center of the brain. It receives afferent impulses from sensory receptors
located throughout the body and processes the information for distribution to the appropriate cortical
area. It is also responsible for regulating consciousness and sleep.
Homeostasis (Homeostatic State) - ✔✔Normal state in which there is minimal variation in respiration
and circulation.
Pharmacokinetics - ✔✔The effects that the body has on drugs or what the body does to the drug
Pharmacodynamics - ✔✔The effects that the drug has on various body systems.
primary and secondary effects.
Rapid Redistribution - ✔✔Short acting drug only remain attached to the receptor sites for a short time
and then move to the other tissues.
PO (per os) - ✔✔Through the mouth.
(Delayed onset, unpredictable effects, patient compliance, not good when patient is nauseated)
Subcutaneous (SQ) - ✔✔Beneath the Skin
