  1. Gate Control Theory
    theory that states that the transmission of a nerve impulse can be modulated at various points along its path by descending fibers from the brain that close the "gate" and block transmission of pain information and by A fibers that are able to block transmission in the dorsal horn by closing the gate for transmission for the A-delta and C fibers
  2. Narcotics
    drugs, originally derived from opium, that react with specific opoid receptors throughout the body
  3. Narcotic Agents
    drugs that react at opoid receptor sites to stimulate the effects of the receptors
  4. Narcotic agonists-antagonists
    drugs that react at some opoid receptor sites to stimulate their activity and at orther opoid receptor sites the block activity
  5. Narcotic antagonists
    drugs that block the opoid receptor sites; used to counteract the effects of narcotics or to treat an overdose of narcotics
  6. Narcotic Agonist
    Prototype: Morphine (Roxanol)
    • *Metabolize in liver. Excrete in urine and bile
    • *Schedule 2 - risk for dependency
    • *(IV-push, PCA pump) patient-controlled. continuous low dose. IM, SubQ, IV-short term relief (2 hours), Oral-long term relief (2-4 hours)
    • Actions: Produce analgesia, sedation, sense of well-being
    • Indications: severe, acute, chronic pain, preop medication with anesthesia
    • Contraindications: recent GI or GU (slows motility) surgery; head & CVA (mask symptoms) injuries, respiratory dysfunction, liver or renal dysfunction, pregnancy, lactation
    • Adverse effects: respiratory, CV, CNS (sweat, hallucinations, pupils constrict, impaired mental process, anxiety), GU, GI (constipation)
    • Drug-drug interactions: CNS and CV effects increased. phenothiazines, MAOIs, barbituates
    • Nursing considerations: Monitor vitals, CNS assessment with pupil response, palpate abdomen and bladder, pain assessment, monitor timing of dosage, additional measures to relieve pain, monitor respiratory status, comfort and safety measures, monitor response to drug, monitor for adverse effects
  7. Narcotic Agonists-Antagonists
    Prototype: Pentazocine (Talwin)
    • Less potential for substance abuse, but more psychotic
    • IV and Oral
    • Metabolize in liver. Excrete in Kidneys.
    • Actions: Sedation and analgesia (dysphoria and hallucintations)
    • Indications: Moderate to severe pain, adjunct to anesthesia, labor and delivery
    • Contraindications: more psychotic-like reaction, COPD (respiratory depression), Acute MI (stimulate cardiac arrhythmias), allergies, renal and hepatic dysfunction
    • Adverse effects: respiratory depression, GI (decrease motility), GU (urinary spasm), dizziness, tachycardia, palpations
    • Drug-drug interactions: barbituates (increase respiratory depression, hypotension, sedation or coma)
    • Nursing Considerations: Monitor vitals, CNS assessment with pupil response, palpate abdomen and bladder, pain assessment, monitor timing of dosage, additional measures to relieve pain, monitor respiratory status, comfort and safety measures, monitor response to drug, monitor for adverse effects
  8. Narcotic Antagonist
    Prototype: Naloxone (Narcan)
    • Metabolize in liver. Excrete in kidneys.
    • IV push (< 1 min.)
    • IV***, SubQ, IM
    • Actions: reversal of narcotic agent
    • Indications: reversal of narcotic depression, diagnosis of suspected overdose
    • Contraindications: pregnancy, narcotic addiction, CV (chest pain, SOB-Increase BP and pulse) disease
    • Adverse effects: Acute narcotic abstinence syndrome (nausea, vomiting, sweating, tachycardia, fall in BP, hypotension, hypertension, pulmonary edema)
    • Nursing Considerations: Maintain open airway, Order pain meds or sedation, Monitor vitals, CNS assessment with pupil response, palpate abdomen and bladder, pain assessment, monitor timing of dosage, additional measures to relieve pain, monitor respiratory status, comfort and safety measures, monitor response to drug, monitor for adverse effects
