Prolonged Field Care (PFC) represents one of the most demanding challenges in military medicine. When evacuation is delayed — sometimes by hours or even days — the combat medic must transition from the rapid, algorithmic interventions of Tactical Combat Casualty Care (TCCC) into the role of a sustained care provider.
This guide covers the core principles of PFC, the clinical priorities that shift when the "golden hour" has passed, and how simulation-based training prepares medics for the cognitive and procedural demands of extended casualty management.
What Is Prolonged Field Care?
Prolonged Field Care is defined as field medical care applied beyond the typical one-hour evacuation window, performed by military medical personnel to prevent death or further injury until the casualty can be evacuated to a higher level of care.
PFC is not a new concept — it has been practiced in remote and austere environments for decades. What is new is the formal recognition by the Committee on Tactical Combat Casualty Care (CoTCCC) that medics need dedicated training for this phase of care.
The Shift from TCCC to PFC
TCCC: Rapid, Algorithmic, Life-Saving
TCCC focuses on the three leading causes of preventable battlefield death:
Extremity and junctional hemorrhage — tourniquets, wound packing, and junctional devices
Tension pneumothorax — needle decompression of the chest
These interventions are fast, protocol-driven, and designed for the chaos of direct fire.
PFC: Sustained, Adaptive, Comprehensive
Once the casualty is stabilized and evacuation is delayed, the medic must shift to:
Reassessment of all TCCC interventions (tourniquet conversion, wound re-packing)
IV/IO access and fluid resuscitation
Pain management and sedation
Monitoring of vital signs, urine output, and mental status
Documentation for continuity of care at the next echelon
Core PFC Clinical Priorities
1. Hemorrhage Control Reassessment
Tourniquets placed under fire must be reassessed. Check for:
Proper placement (2–3 inches above the wound)
Adequate tightness (no distal pulse)
Time of application (document clearly)
Conversion to wound packing if anatomically appropriate
2. Airway Management
In PFC, airway management becomes more complex:
Reassess the nasopharyngeal airway for position and patency
Consider supraglottic airway (King LT, i-gel) for unconscious casualties
Surgical cricothyrotomy remains the definitive field airway for failed airways
3. Fluid Resuscitation
The PFC approach to fluids follows damage control resuscitation principles:
Permissive hypotension: titrate to a palpable radial pulse, improved mental status, or SBP of about 100 mmHg (100–110 if BP monitoring is available); suspected moderate/severe TBI requires SBP above 100 mmHg
Whole blood or 1:1:1 ratio (packed red cells : plasma : platelets) when available
Limit crystalloids — normal saline and lactated Ringer's worsen coagulopathy
Use ketamine (0.3 mg/kg — about 20–30 mg — slow IV/IO, repeated as needed) or oral transmucosal fentanyl
Missed secondary injuries
Blast injuries are often multi-system
Perform a systematic head-to-toe secondary survey
Training for PFC: Why Simulation Matters
PFC scenarios are cognitively demanding in a way that classroom instruction cannot replicate. The medic must:
Maintain situational awareness across multiple casualties
Make treatment priority decisions with incomplete information
Perform procedures under fatigue and stress
Communicate effectively with higher echelons via radio
MilMedSim's PFC simulation scenarios place the learner in exactly these conditions — delayed evacuation, deteriorating vitals, and competing priorities — building the decision-making muscle memory that saves lives.
Key Takeaways
PFC begins when TCCC stabilization is complete and evacuation is delayed
Reassessment, monitoring, and documentation are the pillars of PFC
Damage control resuscitation principles apply: permissive hypotension, limit crystalloids
Simulation training is the most effective preparation for the cognitive demands of PFC
Mastering TCCC tourniquet application is vital for combat medics. Learn when, where, and how to apply, avoiding common errors to maximize effectiveness and save lives on the battlefield.
