 Emergency Support Function
     (ESF) 8 OVERVIEW
 DHH has the role of providing leadership for planning,
 directing and coordinating the overall State efforts to
 provide public health and medical assistance.
 The Secretary of Health and Human Services through
 the Office of Public Health Emergency Preparedness is
 responsible for the federal coordination.
 The command and control of operations are consistent
 with the National Response Framework and compliant
 with National Incident Management System
 requirements.

         Unified Command
 Enables all agencies with
  responsibility to manage an
  incident together by
  establishing a common set
  of incident objectives and
  strategies.

 Allows Incident Commanders
  to make joint decisions by
  establishing a single
  command structure.

 Maintains unity of command.

                If signs/symptoms
                progressing continue antidote
                administration.

                If breathing has stopped or is
                difficult use artificial

HOSPITAL MANAGEMENT
           Hospital’s Role
 Ventilatory support: patients with respiratory failure
  and compromised airways will require immediate
  endotracheal intubation and positive pressure
  ventilation.
 Oxygen supplement
 Decontamination before entering the emergency
  department
 Suctioning for removal of bronchial secretions
 Gastric decontamination-activated charcoal
           Hospital’s Role
 Observation
 Treatment-Atropine and Pralidoxime
 Monitoring for seizure activity (administering
  anticonvulsants for prevention)
 Recovery may take several months
 Risk of permanent damage to the Central Nervous
  System (high dose exposure)
 Consult with the Louisiana Poison Center

1.   Mild/Moderate effects of nerve agents include localized sweating, muscle fasciculations, nausea, vomiting, weakness, dyspnea.
2.   Severe effects of nerve agents include unconsciousness, seizures, apnea, flaccid paralysis.
3.   Dose selection of 2-PAM chloride for elderly patients should be cautious (usually starting at 600 mg IM, or 25 mg/kg IV slowly) to account for the
     generally decreased organ functions in this population.
NOTE: 2-PAM chloride (2-PAM) is pralidoxime chloride, trade name Protopam®.
CHEMPACK: CHEMPACK is a federal program to provide nerve agent antidotes (Atropine, 2-PAM, Diazepam) to during an emergency.

      CHEMPACK Response
      Operation Overview
 Step 1: Event- a suspected chemical or biological
  incident occurs. 911 is notified of the situation and the
  need for security considerations or medical attention
  for/by the public. At this time, 911 operators also
  notify the parish Office of Homeland Security and
  Emergency Preparedness of the event.
 Step 2: Isolation- security and medical responders
  will follow local parish protocol for isolation and triage
  for treatment.
     CHEMPACK Response
     Operation Overview
 Step 3: CHEMPACK Standby/Alert- the Louisiana Poison
 Center will be notified by either the field Incident
 Commander or the 911 Operations Center that there is a
 suspected nerve or organophosphate incident. Triaging
 assistance is provided to the Incident Commander an on-
 scene first responders. Since positive identification of the
 substance involved is nearly impossible in the initial
 response, symptoms consistent with a nerve agent or
 organophosphate exposure will be sufficient for
 recommending appropriate treatment and release of the
 assets.
         Louisiana Poison Center: 1-800-222-1222
     CHEMPACK Response
     Operation Overview
 Step 4: CHEMPACK Activation- If the Tier I assets
 are insufficient to meet the need, then the Louisiana
 Poison Center activates this CHEMPACK plan. The
 Louisiana Poison Center will notify appropriate Host
 Sites with a request for Tier II countermeasures via the
 CHEMPACK assets. The Louisiana Poison Center
 considers such factors as wind trajectory, volume of
 patients, and treatment needs when selecting Host
 Site(s) and Receiving Site (s) for CHEMPACK supplies.
 Louisiana Poison Center will notify Host Sites to open
 containers and prepare appropriate “allocations” for
      CHEMPACK Response

distribution. Further, Louisiana Poison Center
  coordinates transportation with Louisiana State Police.
 Step 5: Countermeasures- Tier II CHEMPACK assets
  will be dispensed as per the plan and appropriate
  Regional plan(s).
 Step 6: Collection/Transportation of a Specimen-
  A request may be made to transport a sample of the
  substance/agent to the State Lab for analysis.
