DAANCE Module 3- Anesthetic Drugs & Techniques with Absolute Solution

DAANCE Module 3- Anesthetic Drugs & Techniques with Absolute Solution Brevital (Sodium Methohexital) - Primary anesthetic agent introduced in the 1960's. Balanced Anesthesia - Use of several agents together Basic Requisites of an Anesthetic - Lack of toxicity, non-flammable, non-addictive, minimal allergenicity. Analgesia - Given to feel no pain (ex: Fentanyl and Local) Amnesia - Benzodiazepines (ex: Versed) Relaxation & Immobility - 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. Anxiolytic (Anxiety Reducing) Meds - Diazepam or Midazolam Relay Center - Sensory neurons that sense pain pass through this. Homeostasis (Homeostatic State) - Normal state in which there is minimal variation in respiration and circulation. Pharmacokinetics - The effects that the body has on drugs. Pharmacodynamics - The effects that the drug has on various body systems. 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 pt in nauseated) Subcutaneous (SQ) - Beneath the Skin (Absorption is somewhat delayed compared to IM or IV) Intramuscular (IM) - In the muscle (Unpredictable onset of drug effect, cannot titrate the dose) Intravenous (IV) - In the vein Inhalation Route - Inhaled (Very rapid absorption and titration) 4 Levels of Continuum - Minimal Sedation, Moderate Sedation, Deep Sedation (Analgesia), and General Anesthesia Minimal Sedation (Anxiolysis) - Normal response to verbal stimulation, cardiovascular function unaffected.
