Detailed Notions on Trauma, Crisis, and Disaster in Health Care

Impact of Trauma, Crisis, Disaster on Health

  • Objectives:
    • Describe the impact of trauma, crisis, and disaster on health.
    • Explore risk factors contributing to clients experiencing trauma, crisis, or disaster.
    • Differentiate clinical presentations of trauma, crisis, or disaster-related disorders.
    • Explore the role of the nurse caring for clients experiencing trauma.
    • Develop a plan of care for those experiencing trauma, crisis, or disaster.

Understanding Trauma

  • Prevalence:
    • Approximately 70% of adults have experienced trauma.
    • Types of trauma include:
    • Physical assaults
    • Sexual assaults
    • Accidents
    • Natural disasters
    • Combat
    • Witnessing violence
    • Hospitalization or severe illness
  • Varied Responses to Trauma:
    • Influence of age: Children are at increased risk due to neuroplasticity.
    • Attachment theory: Quality of early attachments can affect responses.
    • Developmental level: Dependency and vulnerability play roles.
    • Coping skills: Resilience and prior experiences shape responses.
    • Support: Health disparities and family support can mitigate risks.
    • Cognitive deficits: Can complicate responses to trauma.
    • Neural physiology: Conditions like TBI affect trauma responses.
    • Genetics: Biological predispositions may influence reactions.

Neurophysiology of Trauma

  • Information Processing:
    • Environmental information is matched with prior experiences to determine responses.
  • Key Brain Regions:
    • Amygdala: Involved in fear and aggression, stores traumatic memories.
    • Prefrontal Cortex: Responsible for decision-making, modulates amygdala responses.
    • HPA Axis: Activated under stress, leading to cortisol release, influencing immune function.
  • Polyvagal Theory: Describes how the brain communicates with the body during traumatic responses (fight/flight/freeze/fawn).
  • Dissociation: A parasympathetic response aimed at reducing emotional arousal.

Fear Learning and Memory

  • Fear Conditioning:
    • Biological memory formation around traumatic events triggers fight/flight responses.
  • Memory Consolidation:
    • The hippocampus stores memories, helping to protect against future threats.
  • Hypervigilance:
    • Increased alertness due to a perceived threat.
  • Fear Extinction:
    • The process of reducing autonomic responses, restoring safety and equilibrium.

Types of Trauma

  • Acute: Examples include a car accident or assault.
  • Chronic: Long-term effects of abuse, poverty, or neglect.
  • Complex: Includes social inequity and discrimination.
  • System-Induced: Experiences from detention systems or foster care.
  • Vicarious Trauma: Experienced by healthcare providers or first responders.
  • Generational/Historical Trauma: Passed down through generations, influenced by community adverse experiences.
  • Epigenetics: Trauma's effects can be genetically influenced.

Trauma-Related Disorders

Attachment Disorders
  • Reactive Attachment Disorder: Characterized by withdrawal in children.
  • Disinhibited Social Engagement Disorder: Children are overly friendly with strangers, stemming from inadequate caregiving.
Post-Traumatic Stress Disorder (PTSD)
  • Criteria: Requires exposure to a traumatic event, symptoms may arise months/years later.
  • Symptoms:
    • Intrusive memories, flashbacks, and avoidance of trauma-related stimuli.
    • Hypervigilance, irritability, sleep disturbances, and negative cognition.
  • Diagnosis: At least one month of symptoms, evaluated using screening tools like PC-PTSD-5 and PCL-5.
PTSD in Children
  • Manifestation: Symptoms may present through play, behavior problems, and academic difficulties.
  • Somatic Complaints: Common issues include stomach aches and headaches.
Acute Stress Disorder (ASD)
  • Symptoms: Similar to PTSD but occurs 3 days to one month after the trauma.
  • Treatments: Similar screening and treatment approaches as PTSD.
Adjustment Disorder
  • Characteristics: Milder symptoms in response to stressors, resolved in less than six months.
  • Common Symptoms: Guilt, anxiety, depression, somatic complaints, social withdrawal.
  • Treatment: Psychotherapy and medications may be utilized.

Traumatic Brain Injury (TBI) and PTSD Overview

  • Symptoms of TBI:
    • Headaches, dizziness, nausea, sensitivity to light/sound, impulsivity.
  • Overlap with PTSD Symptoms: Fatigue, sleep problems, memory issues, anxiety, and irritability.

Treatment for PTSD

  • Therapeutic Approaches:
    • Cognitive Behavioral Therapy (CBT), EMDR, Expose therapy, Group therapy.
  • Medications:
    • SSRIs (sertraline, paroxetine) approved for PTSD; benzodiazepines (risk dependence), Propranolol/Metoprolol for physical symptoms, and Prazosin for nightmares.

Staged Model of Treatment for Trauma

  1. Stage 1:
    • Focus on safety and stabilization; educate about trauma.
  2. Stage 2:
    • Teach relaxation techniques; regulate emotions; manage memories.
  3. Stage 3:
    • Develop problem-solving skills, foster social support, establish client goals.

Nursing Care in Trauma

  • Trauma-Informed Care Principles:
    • Safety, transparency, and trustworthiness.
    • Importance of collaboration, empowerment, and addressing cultural issues.
  • Nursing Interventions:
    • Safety assessments, teaching coping strategies, medication administration, and team collaboration.

Crisis Intervention Overview

  • Definition: Time-limited, directive strategies for individuals in grave stress.
  • Crisis Types:
    • Maturational, Situational, Adventitious.
    • Individuals may face multiple crisis types simultaneously, complicating recovery.
  • Impacts: Perceptions of stressors, available situational supports, and coping mechanisms address equilibrium vs. disequilibrium.

Disaster Management for Nurses

  • Phases:
    • Pre-Disaster: Prevention and preparedness.
    • Disaster: Immediate response to the impact.
    • Post-Disaster: Recovery efforts.
  • Prioritizing Client Needs in Disaster:
    • Assess problems and challenges, evaluate coping skills and resources to assist in planning personalized care strategies.
