Presentation Transcript

  1. Medication Use in the Trauma Bay Nicole Acquisto, Pharm.D., BCPS Emergency Medicine Clinical Pharmacy Specialist, Department of Pharmacy Senior Instructor, Department of Emergency Medicine

  2. Overview • RSI (Pre-induction, Sedation, Paralysis) • Procedural Sedation • Post-intubation sedation • Analgesia • Code Tray Medications • Cardiac Medications • Vasopressors • Antibiotics • Stroke • Miscellaneous

  3. Rapid Sequence Intubation Pretreatment Time zero minus 3 minutes Sedation Time zero Paralytic Time zero Intubation Time zero plus 45 seconds

  4. Pharmacologic Agents used for RSI

  5. Airway Cart Med-Box • Etomidate – 40mg/20mL • Succinylcholine – 200mg/10mL • Rocuronium– 50mg/5mL • Lidocaine – 100mg/10mL • Epinephrine 1:10,000 – 1mg/10mL • Atropine – 1mg/10mL

  6. Pharmacologic Agents used for RSI

  7. Atropine Anti-cholinergic agent Used to prevent bradycardia associated with intubation (succinylcholine)

  8. Lidocaine • Class Ib anti-arrhythmic • Head injury • May blunt increase in ICP due to intubation • May decrease pressor response

  9. Pharmacologic Agents used for RSI

  10. Etomidate • Carboxylatedimidazole derivative, non-barbiturate sedative hypnotic • No analgesic activity • Advantages • Minimal cardiovascular effects • Cerebral protective effects  reduces cerebral blood flow and cerebral oxygen uptake  decreasing ICP

  11. Etomidate • Adverse effects • Myoclonus (up to 30%) • Adrenocortical suppression

  12. Ketamine • Dissociative anesthetic • Sedative and analgesic properties • Little or no respiratory or cardiovascular depression • Available in 200 mg/20 mL vials (in the Pyxis)

  13. Ketamine

  14. Ketamine • Adverse effects • Emergence phenomenon (12%) • Hallucination and emotional distress • May last a few hours • Can prevent with benzodiazepines • Increase in salivation and bronchial secretions • Glycopyrrolate or atropine • Sympathomimetic effects • Can produce cardiac ischemia by increasing CO and BP • Nausea/Vomiting • Cerebral vasodilator – increase ICP

  15. Midazolam • Benzodiazepine, Sedative hypnotic agent • Anticonvulsant effects • No analgesic activity • Large doses needed and variable effectiveness for RSI

  16. Propofol Propofol(Procedural or Continuous) • Sedative hypnotic agent • Advantage • Very rapid onset of effect • Rapid offset • Antiemetic and anticonvulsant properties • Decreases ICP • Adverse Effects/Disadvantages • Hypotension (pulmonary vasodilator) • Can decrease cerebral blood flow and perfusion • Bradycardia and  CO • Contraindicated in egg/soy allergy • Short-acting sedative hypnotic • NO analgesia • May have anticonvulsant properties (at high doses) • Pharmacokinetics • Onset: 10-50 seconds • Duration: 3-10 minutes (quick onset/offset) • Dose • 0.5-1 mg/kg IV x1, then 0.5 mg/kg q2-3minutes to desired effect • 0.5-1 mg/kg load, then 10-20 mcg/kg/min  titrate (usual: 20-80 mcg/kg/min) • Pregnancy Category B • Adverse Effects • Hypotension (3-26%), respiratory depression • Pain at the injection site • Hypersensitivity reactions (avoid in patients with egg/soy allergies)

  17. PropofolDon’t stop ‘til you get enough…

  18. Pharmacologic Agents used for RSI

  19. Neuromuscular Junction • Major Components • Motor nerve terminal • Neurotransmitter • Acetylcholine • Postsynaptic muscle endplate

  20.
