Strategic National Stockpile • 1999: Charge to establish a national stockpile • Congressional charge to: • Department of Health and Human Services (DHHS) and • Centers for Disease Control and Prevention (CDC) • Called: • The National Pharmaceutical Stockpile (NPS) • 2003: The NPS becomes the Strategic National Stockpile (SNS). • Large quantities of essential medical materiel • For states and local public health agencies • During an emergency
A single “push package” weighs 94,424 pounds and fills either one wide-body aircraft or seven tractor trailers.
SNS Deployment • Maine CDC asks governor to request SNS deployment. • Partial or complete Push Packages arrive within twelve (12) hours of the federal decision to deploy. • Push Package contents are constantly updated but contain in general: • Antibiotics - IV administration supplies • Nerve agent antidotes - Airway maintenance supplies • Antitoxins - Medical/surge items. • Life-support medications • Technical Advisory Response Unit (TARU) is sent. • TARU staff coordinate with state and local officials. • SNS assets are efficiently received and distributed.
Vendor Managed Inventory • Additional supplies • Pharmaceuticals and/or medical • After 12-hour push packages (if needed) • Within 24 to 36 hours • First option • If 12-hour turnaround not needed • If need is specific to certain known items OR
Other Supplies • US Postal service: • Ciprofloxacin and doxycycline • At MMC and EMMC • Maine EMS: • Atropine/2-PAM autoinjectors • In ambulances • Training requirements
Antidotes • CHEMPACK • Nerve agent antidotes • Maine Pharmaceutical Cache • Nerve agent antidotes • Chelating agents (heavy metals/radiation) • Antibiotics • Toxic alcohol antidote • Cyanide antidote • Radiation (power plant-related)
Nerve Agents Antidotes in: CHEMPACK Maine Pharmaceutical Cache Strategic National Stockpile
Effects of Nerve Agents • Muscarinic (Atropine works) • Smooth muscles • Exocrine glands • Nicotinic (Atropine ineffective, 2-PAM works) • Skeletal muscles • Ganglia (Sympathetic/Parasympathetic) • Central Nervous System (Diazepam works)
Muscarinic Effects Increased secretions • Saliva • Tears • Runny nose • Secretions in airways • Secretions in gastrointestinal tract • Sweating Smooth muscle contraction • Eyes: miosis (Can use Lidocaine 2%) • Airways: bronchoconstriction (shortness of breath) • Gastrointestinal: hyperactivity (nausea, vomiting, and diarrhea)
Nicotinic Effects • Skeletal muscles • Fasciculations • Twitching • Weakness • Flaccid paralysis • Other (ganglionic) • Tachycardia • Hypertension
Other Signs & Symptoms • Cardiovascular • Bradycardia (muscarinic, late nicotinic) • Tachycardia (nicotinic) • Heart block, ventricular arrhythmias • Central Nervous System • Loss of consciousness • Seizures • Apnea
ATROPINE Antagonize muscarinic effects Dry secretions Relax smooth muscles Give IV,IM,ET Starting dose 2mg, cumulative dose 20mg (insecticides may require much larger doses – grams or more in severe cases) PRALIDOXIME Cl (2PAM-Cl) Remove nerve agent from AChE in absence of aging 1-2 g IV over 15-30min 5 minutes is possible/not ideal Rapid IV = hypertension Helps at nicotinic sites Nerve Agents Treatment • DIAZEPAM • Treats seizures (Other less-understood beneficial effects)
Nerve Agent Treatment-EMS State of Maine (Mark 1 kits = NAAK): EMTs can only administer to EMTs (self or other EMTs) Treat yourself first and then others Escape the Area/ Notify Dispatch Decontaminate (strip down / H2O) DO NOT ENTER ONCE SUSPICION EXISTS IF Symptomatic use the NAAK Kits: Atropine 2-PAMCl NAAK = Nerve Agent Antidote Kit Mark I = a brand name for NAAK
Chelating Agents Antidotes in: Maine Pharmaceutical Cache
Chelation & Heavy Metal Poisoning • BAL (British anti-Lewisite, dimercaprol): • Lewisite gas (systemic toxicity) • DMPS (Unithiol): • Arsenic, bismuth?, lead, mercury • EDTA, calcium disodium & Succimer: • Lead (Zinc) • Prussian Blue: • Poisoning: thallium
Dimercaprol & DMPS (Unithiol) BAL (British anti-Lewisite) or Dimercaprol: Developed to treat Lewisite An arsenic based poison gas Injection in peanut oil given IM every 4 hours initially Maine has supply in largest hospitals DMPS (Unithiol): Water soluble analog of BAL Injection initially, then orally Maine has supply in largest hospitals
EDTA, calcium disodium • Lead: • Mostly replaced by DMPS, except in severe cases • Important not to give BAL 1st in severe overdoses • Then should be given together (BAL and EDTA) for early doses • Confusion with sodium EDTA can lead to life-threatening hypocalcemia • Maine has supply in largest hospitals • Other possible uses: • Zinc • Manganese • Certain types of radiation exposure
Action: Block GI absorption, enterohepatic recirculation Dose: Up to 10 g daily for acute thallium poisoning 1 gm with 4oz water p.o. t.i.d. Duration: Possibly several days or more Maine has supply of powder to be used until commercial supplies obtained Prussian Blue (Ferric hexacyanoferrate)
