Title: PDLS: Children as Victims of Terrorism: Risk Assessment


1
PDLS Children as Victims of Terrorism Risk
Assessment Response
  • Jim Courtney, DO

2
Objectives
  • Identify why children can be specific targets of
    terrorism
  • Discuss the differences that may make children
    more susceptible to certain acts of terrorism
  • Discuss specific treatment modalities and/or
    dosing that are unique to children

3
Guiding Principles
  • The best approach to disaster preparedness is to
    plan for all pertinent hazards.

4
Guiding Principles
  • Dont need separate disaster plans for kids
  • Do need to focus on their unique needs and the
    critical differences between children and adults

5
Pediatric Issues in Terrorism
  • Children at risk
  • Assessing your communitys risks
  • Community preparation issues
  • Family preparation issues
  • Psychological issues with children
  • Resources

6
Collateral damage?
FEMA Photo Library
7
Or intentional targets?
  • When Lee Malvo asked why he planned to attack
    children in schools and on buses, convicted
    sniper John Mohammed allegedly replied
  • For the sheer terror of it the worst thing you
    can do to people is aim at their children.


    (From AP story 5/30/06)

8
Children at Risk Targets
  • Innocent, vulnerable population
  • Tend to gather in large groups, including daycare
    centers at places of business
  • Natural curiosity
  • May not be able to rescue themselves
  • Extreme emotional reaction by rescuers and public

9
Children at Risk Vulnerabilities
  • Low to ground
  • Faster respiratory rates
  • Larger skin surface area to mass ratio
  • Vulnerable to fluid loss

10
Children at Risk Vulnerabilities
  • More permeable blood-brain barrier
  • Many rapidly reproducing cells
  • Unable to escape (longer exposure)
  • Found in large groups (contagion)

11
Community Preparation
  • EMS/Fire
  • Incorporate children in all MCI drills and
    exercises
  • Knowledge of at-risk groups in the area
  • Knowledge of local hospital pediatric
    capabilities
  • Have appropriate protocols/aids for pediatric
    WMD/WME care

12
Community Preparation
  • Hospitals
  • Incorporate the needs of children and families
    into all aspects of disaster planning and
    preparedness
  • Acknowledge the likelihood of an unusual
    pediatric patient load in the disaster setting
  • Be aware of available pediatric resources

13
Community Preparation
  • All medical responders/receivers must be prepared
    to deal with
  • Lack of familiarity with pediatric antidotes and
    treatments and lack of pediatric drug
    formulations
  • Unusual pediatric patient loads and acuities
  • Relative lack of local pediatric specialty
    resources due to overwhelming patient volume
  • Ethical dilemmas in resource-constrained
    environments

14
There may be proportionally
  • MORE KIDS THAN ADULTS THAT ARE SICK

15
And children may be
  • SICKER
  • THAN THE ADULTS

March 20, 1995
  • 815 AM Terrorists placed and released
    multiple containers of the nerve gas sarin in 5
    trains on three of Tokyo's ten underground rail
    lines
  • The sarin was concealed in lunch boxes
    plastic/paper bags.
  • The terrorists punctured the bags with umbrellas
    and ran out of the subway tunnel.

19
Tokyo Sarin Attack
  • 5500 injured and 12 dead
  • The same cult had released sarin in an apartment
    complex in Matsumoto in 1994, killing 7 and
    injuring more than 600

  • 845AM first aid stations were set up on the
    streets outside many of the subway entrances
  • 550 patients transported to the ED by ambulance
  • 3227 people evaluated in an ED

27
G Agents
  • Named such because they were 1st synthesized by
    German scientists
  • Chief scientist was Gerhard Schrader
  • Was looking for a more potent insecticide
  • GA (Tabun) discovered in 1936
  • GB (Sarin) discovered in 1938
  • GD (Soman) discovered in 1944
  • GF (Cyclosarin) discovered in 1949

Nerve Gas Furby
  • This cute and cuddly little Furby contains
    enough nerve gas to take down a shopping mall.
    Easy to operate just set the timer and leave it
    behind.
  • 1,750.00
  • From Butlers Military Hardware Salvage Shop

35
V Agents
  • V stands for Venomous
  • As a group approximately 10 times more potent
    than Sarin
  • Persistent agents with an oil consistency
  • Does not wash away easily, can remain on clothes
    for long periods
  • Contact hazard is primarily but not exclusively
    dermal

36
VX
  • High viscosity and low volatility
  • Texture feel of high grade motor oil
  • Odorless and tasteless
  • Can be distributed as a liquid or vaporized
  • Deadliest nerve agent produced to date
  • Possessed only by US and Russia

37
VX Lethal Dose 50
38
Prehospital Decontamination
  • First responders Respirators, goggles,
    protective clothing
  • Self-contained breathing apparatus (SCBA) is
    recommended in response to any nerve agent vapor
    or liquid
  • Butyl rubber gloves
  • 20 of healthcare workers in Tokyo had mild
    symptoms after taking care of patients. These
    symptoms included nausea, eye pain, and headache

39
Atropine
  • Anticholinergic agent
  • Blocks effects of excess acetylcholine
  • Treats muscarinic effects
  • Secretions
  • Gastrointestinal hypermotility

  • Respiratory status is endpoint of treatment

40
Atropine
  • Dosage
  • 2-10 mg IV
  • Repeat as necessary
  • Endpoint of treatment is reduction of
    bronchorrhea and decreased shortness of breath
  • May require large doses (?15-20 mg/hr)

41
Pralidoxime (2-PAM)
  • Regenerates cholinesterase bound by nerve agent
  • Breaks nerve agent-acetylcholinesterase bond
  • Ineffective after aging
  • Treats nicotinic effects
  • Muscular weakness/paralysis

42
Pralidoxime
  • Dosage 15 25mg/kg IV or IM

POSSIBLE INJECTION SITES

Strategic National Stockpile
  • SNS is a national repository
  • Antibiotics, chemical antidotes, antitoxins,
    life-support medications, IV administration,
    airway maintenance supplies, and medical/surgical
    items.
  • Supplement and re-supply state and local public
    health agencies in the event of a national
    emergency

52
Strategic National Stockpile
  • SNS organized for flexible response
  • Push Packs Goal delivery in 12 h
  • Caches of pharmaceuticals, antidotes, and medical
    supplies designed to provide rapid delivery of a
    broad spectrum of assets for an ill defined
    threat in the early hours of an event.
  • Vendor Managed Inventory Goal
    delivery in 24-36 hours
  • VMI can be tailored to provide pharmaceuticals,
    supplies and/or products specific to the
    suspected or confirmed agent(s).

  • Questions regarding
  • Indications
  • Role
  • Should one use Pediatric AtroPen or the Mark I
    Kit?
  • Indications
  • Protocols
  • Stockpile

57
Benzodiazepines
  • Most reliable agents for seizures from nerve
    agent toxicity
  • Prevention and treatment
  • Diazepam autoinjector

59
Biological Agents
  • Typically the treatments are not something
    usually recommended for children
  • Ciprofloxacin or doxycycline for Anthrax
  • Smallpox vaccine for Smallpox
  • Alternatives are not included in the SNS Push
    Pack
  • Contraindications become very relative in
    situations like that

65
Chernobyl Experience
  • 134 workers were treated for radiation sickness
  • 22 had gt 400 rad exposure 32 of those died
  • 21 had gt 600 rad exposure 95 of those died
  • The larger problem is the risk of cancers,
    especially thyroid, leukemia and lung cancer

Your Friends During A Radiation Exposure
  • Time, Distance Shielding
  • The most important things you can do to protect
    yourself
  • Potassium Iodide (KI)
  • Fill your thyroid with iodine so that I131 wont
    deposit there
  • Potassium helps to rid the body of Cesium137
    faster
  • Goal is to have this in the hands of everyone
    within 2 hours of exposure

EMS Protocols
  • How many systems have Chemical, Biological
    Radiological, Nuclear and Explosive (CBRNE)
    protocols?
  • Do they address children?
  • Do they allow for the treatment of children?
