Emergency Medical Services

On this page

  • Goal: Rapid, coordinated medical care to reduce mortality & morbidity in emergencies.
  • Core Components:
    • Detection & Access: Public alert (e.g., 108 helpline).
    • Dispatch: Prioritization & resource allocation.
    • Pre-hospital Care: First Aid, Basic Life Support (BLS), Advanced Life Support (ALS).
    • Transport: Ground/air ambulances (Types B, C, D based on care level).
    • Definitive Care: Hospital stabilization & treatment.
  • Golden Hour: Critical period post-trauma (ideally <1 hour) for intervention to improve outcomes.
  • Chain of Survival: Early Access → Early CPR → Early Defibrillation → Early Advanced Care → Post-Cardiac Arrest Care.

⭐ The "Golden Hour" in trauma emphasizes that definitive surgical care within the first 60 minutes of injury significantly improves survival rates.

Triage Systems - Sorting the Chaos

  • Prioritizes casualties by severity & prognosis; "Do most good for most people."
  • Common Systems:
    • START (Simple Triage And Rapid Treatment): Adults. Uses 📌 RPM (Respirations, Perfusion, Mental Status).
      • Respirations: >30/min or <10/min → Red. Absent (after airway opening) → Black.
      • Perfusion: Capillary Refill >2s / No radial pulse → Red.
      • Mental Status: Cannot obey commands → Red.
    • SALT (Sort, Assess, Lifesaving Interventions, Treatment/Transport): More comprehensive.
  • Color Codes (WHO):
    • 🔴 Red (Priority I): Immediate.
    • 🟡 Yellow (Priority II): Delayed.
    • 🟢 Green (Priority III): Minor/Ambulatory.
    • Black (Priority 0): Expectant/Deceased.

⭐ START Triage: Remember 📌 RPM (Respirations >30/min, Perfusion cap refill >2s, Mental status altered). One positive finding often categorizes patient as RED (Immediate).

On-Site & Transit Care - Mobile Medics

  • Mobile Medical Teams (MMTs): Rapidly deployed for field medical care & stabilization before/during evacuation.
    • Aim: "Scoop and Run" vs "Stay and Play" depends on context & available resources.
    • Equipped for advanced first aid, Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS).
  • On-Site Priorities:
    • Primary survey: ABCDE (Airway, Breathing, Circulation, Disability, Exposure).
    • Control major hemorrhage (e.g., direct pressure, tourniquet if needed).
    • Immobilize fractures (splinting).
    • Administer analgesia (pain relief).
    • Initiate fluid resuscitation if indicated.
  • Transit Care: Continuous patient monitoring & necessary interventions during transport.
    • Ambulances: Categorized (e.g., Type A, B, C, D in India); ALS (Advanced Life Support) units are mobile ICUs.
    • Air Ambulances (Helicopters/Fixed-wing): For rapid evacuation, difficult terrain, or long distances.
    • Maintain communication with the receiving hospital. Ambulance at hospital entrance

⭐ The "Golden Hour" refers to the critical first 60 minutes following trauma, during which prompt and adequate medical intervention significantly increases the chances of survival and reduces morbidity.

Hospital Response - Surge & Support

  • Hospital Disaster Plan (HDP) Activation:
    • Triggered by events; Incident Command System (ICS) initiated.
  • Surge Capacity: Managing ↑ patient volume.
    • 📌 4 S's:
      • Staff: Mobilize personnel, call-back rosters.
      • Stuff: Medical supplies, equipment.
      • Structure: Convert non-clinical areas to care zones.
      • Systems: Communication, patient tracking.
  • Communication:
    • Internal (departments) & External (EMS, authorities).
  • Patient Management:
    • Secondary Triage: At hospital entry, re-prioritize.
    • Definitive Care Zones: For Red, Yellow, Green tags.
    • Reverse Triage: Expedited discharge of stable inpatients.
  • Support Services:
    • Logistics, Psychosocial support (patients, staff), Security.

⭐ Hospital Incident Command System (HICS) is key for organized response, mirroring on-site ICS.

High‑Yield Points - ⚡ Biggest Takeaways

  • Golden Hour is crucial for trauma survival, dictating immediate intervention needs.
  • Triage (e.g., START/SAVE) rapidly categorizes casualties by severity for prioritized treatment.
  • Key EMS components include access (e.g., 108), communication, pre-hospital care, transport, and definitive care.
  • The Chain of Survival (early access, CPR, defibrillation, advanced care) maximizes cardiac arrest outcomes.
  • Basic Life Support (BLS) and Advanced Life Support (ALS) are foundational emergency response skills.
  • Disaster Medical Assistance Teams (DMATs) are deployed to provide surge medical capacity during mass casualty incidents.
  • Ambulance network (102, 108) forms the backbone of emergency transport in India, crucial in disasters.
