UNIT 9 Nursing management of patient in Emergency and Disaster situations Disaster Nursing
Disaster Nursing is the systematic application of nursing knowledge and skills to address and meet the physical, emotional, social, and spiritual needs of individuals, families, and communities affected by disasters โ whether natural or man-made.
๐ As per WHO:
โDisaster Nursing is the adaptation of professional nursing knowledge, skills, and attitude in recognizing and meeting the nursing, health, and emotional needs of disaster victims.โ
A disaster is a sudden, calamitous event causing great damage, loss of life, and disruption of normal life, requiring immediate response from local, national, and international aid.
๐ Types of Disasters:
Nurses are frontline responders who:
โ
Save lives and minimize health hazards
โ
Provide timely and efficient care
โ
Prevent complications and infections
โ
Promote psychological well-being
โ
Coordinate with multi-disciplinary teams
โ
Support recovery and rehabilitation of victims
Letโs explore the academic principles with symbols and clarity:
๐ง Assessment is the cornerstone of disaster nursing.
๐ Goal: Do the most good for the most people.
๐ฌ Information saves lives.
๐ฉโโ๏ธ Nurses heal wounds โ both visible and invisible.
๐จ Be ready before disaster strikes.
๐ง Efficiency ensures continuity of care.
๐ฆบ The nurse must stay safe to help others.
๐งพ Documentation is a legal, ethical, and medical necessity.
๐ Ethics never stop, even in emergencies.

Disaster policies are the backbone of organized disaster response. With proper frameworks in place, governments and healthcare systems can save lives, reduce suffering, and rebuild faster. For nurses and healthcare professionals, understanding these policies is crucial to contribute effectively during crises and ensure ethical, coordinated, and safe disaster care.
A natural disaster is a catastrophic event resulting from natural processes of the Earth, which causes significant damage to life, property, infrastructure, and the environment.

โ Nurses and healthcare professionals must be trained in:
Man-made disasters pose serious, often preventable risks to health and safety. They highlight the importance of safety protocols, laws, emergency services, and trained nursing professionals. Prevention, mitigation, and rapid coordinated response are essential to minimize damage.
๐ฌ โWhere human errors create crises, trained professionals bring safety, healing, and hope.โ
๐ Disastersโwhether natural or man-madeโcan occur suddenly, leaving behind devastation and requiring an organized, rapid, and skilled response.

(Meaning, Definition, and Etiology)
The term Polytrauma refers to a clinical condition in which a person sustains multiple traumatic injuries simultaneously โ affecting more than one body region, organ system, or function โ often with life-threatening implications.
๐ง The severity is such that the combined effect of all injuries is greater than the sum of each individually, making diagnosis, treatment, and recovery more complex.

Organophosphorus poisoning is a toxic condition caused by the exposure to or ingestion of organophosphate compounds, which are cholinesterase inhibitors commonly found in insecticides, pesticides, and chemical warfare agents.
These compounds inhibit the enzyme acetylcholinesterase, leading to accumulation of acetylcholine at synapses, resulting in overstimulation of cholinergic receptors.
| ๐ Cause | ๐งพ Examples |
|---|---|
| ๐งด Accidental exposure | Farmers spraying pesticides, poor handling/storage |
| ๐ Intentional ingestion | Common in rural suicide attempts |
| ๐ซ Terrorist/warfare exposure | Sarin, soman (nerve agents) |
| ๐จ Inhalation of vapors | Indoor fumigation, contaminated clothing |

| โ ๏ธ Industrial OPs | Trichlorfon, Fenitrothion |
| ๐ฃ Warfare/Nerve Agents | Sarin, Tabun, VX, Soman |
Organophosphates bind to and irreversibly inhibit acetylcholinesterase (AChE) enzyme, preventing the breakdown of acetylcholine (ACh).
1๏ธโฃ ACh accumulates at muscarinic and nicotinic receptors
2๏ธโฃ Causes overstimulation of parasympathetic & somatic nervous system

Thermal emergencies refer to life-threatening conditions caused by abnormal exposure to extreme heat or cold, resulting in impaired thermoregulation and organ dysfunction.
These conditions arise when the body is unable to maintain its core temperature within a safe physiological range (approximately 36.5ยฐCโ37.5ยฐC or 97.7ยฐFโ99.5ยฐF).
“Thermal emergencies are acute medical conditions caused by exposure to excessively high or low environmental temperatures, leading to disruption of body temperature homeostasis, tissue damage, or multi-organ failure.”
They include both heat-related and cold-related emergencies, such as:
Thermal emergencies occur due to failure of the bodyโs thermoregulatory mechanisms, which can be triggered by:

Emergency management involves a systematic, organized approach to prevent, prepare for, respond to, and recover from emergency situations, ensuring protection of life, property, and environment.
Emergencies can be natural, man-made, medical, or technological. Whether it is trauma, burns, cardiac arrest, or natural disasters, certain universal principles guide the response and management.
โEmergency management is the discipline of dealing with and avoiding risks, especially those that have catastrophic consequences, through an organized and coordinated response system.โ
Letโs understand the key principles that guide effective emergency response:
Be ready before an emergency occurs.
โ Example: Hospitals maintain disaster kits, triage tags, and emergency plans.
Identify the situation and needs as quickly as possible.
โ Example: In a road traffic accident, first responders assess airway, bleeding, and consciousness.
Sort patients based on the urgency of their condition.
โ Goal: Treat those who have the highest chance of survival with timely intervention.
Follow the basic resuscitation protocol.
โ Nurses should initiate first aid, CPR, bleeding control, and shock prevention.
Provide treatment based on assessment and protocols.
โ Ensure stabilization before transfer to tertiary care.
Accurate recording and relaying of information.
โ In medicolegal cases (e.g., poisoning), precise documentation is essential.
Work as a multidisciplinary team.
โ Smooth teamwork reduces chaos and increases patient survival.
After the emergency, focus shifts to restoration.
โ Recovery phase is crucial to prevent long-term complications.
Ensure decisions uphold ethics and law.
โ Respect dignity, rights, and autonomy of all patients.
| ๐ Principle | ๐ Key Focus |
|---|---|
| Preparedness | Training, planning, drills, supplies |
| Rapid Assessment | Scene safety, casualty evaluation |
| Triage | Prioritization by urgency |
| Immediate Interventions (ABCD) | Life-saving first aid and stabilization |
| Definitive Care | Treatment, procedures, referrals |
| Documentation & Communication | Records, reports, handovers |
| Teamwork | Multidisciplinary, role-based collaboration |
| Recovery | Rehabilitation, monitoring, mental health care |
| Ethics & Law | Consent, confidentiality, patient rights |
Medico-legal cases (MLCs) are situations where medical care has legal implications and may involve injury, violence, or criminal elements.
| โ ๏ธ Scenario | ๐ก Examples |
|---|---|
| ๐ Road Traffic Accidents | Fractures, head injury |
| ๐ช Assaults / Stab wounds | Domestic violence, fights |
| ๐งช Poisoning / Drug overdose | Suicidal or homicidal intent |
| ๐ฅ Burns | Accidental, suicidal, or dowry-related |
| โฐ๏ธ Unnatural deaths | Sudden, unexplained, suspicious death |
| ๐ง Sexual assault | Rape, molestation |
| ๐ท Occupational injuries | Factory explosions, construction site falls |
โ Every emergency nurse must understand MLC protocols and cooperate with legal teams.
| Step | Action |
|---|---|
| ๐ ฐ๏ธ Airway | Open airway, suction, intubation if needed |
| ๐ ฑ๏ธ Breathing | Give oxygen, assess chest movement |
| ๐ ฒ Circulation | Control bleeding, start IV fluids |
| ๐ ณ Disability | Check consciousness (AVPU or GCS), manage seizures |
โDisaster Nursing is the adaptation of professional nursing knowledge, skills, and attitude in recognizing and meeting the physical and emotional needs of disaster-affected people.โ
