Royal Army College

Lesson Overview

Every earlier lesson assumed help was close. You stopped the bleeding, managed the airway, treated for shock, and handed the casualty on within minutes, into the chain of care described in Lesson 07. But the Royal Kaharagian Army's likeliest work, remote search-and-rescue and disaster relief, will not always be so kind. A casualty may lie on a mountainside above a washed-out track, or in a flooded valley a day from the nearest hospital, with the weather closing in and no aircraft able to fly. The wounds are the same. What changes is time. You are no longer keeping a casualty alive for minutes; you are keeping them alive for hours.

The Army calls this prolonged or austere casualty care: sustaining a casualty over a long wait when evacuation is delayed by distance, weather, or a cut road. The skills do not change, but the mindset shifts from "treat and evacuate fast" to "sustain over time". You go round the casualty again and again, protect them from an environment that can kill as surely as the wound, and keep a clear record so your handover is clean whenever help comes. The 10-1-2 timeline of Lesson 07, life-saving aid in ten minutes, advanced care in an hour, surgery in two, is what the chain of care reaches for; this lesson is what you do when it cannot be met and the gap must be held by you. None of it is more advanced than basic first aid, but it asks something harder than cleverness: endurance, patience, and a refusal to let a casualty drift while you wait. The limit of Lesson 08 still holds: you are a first-aider who sustains and summons, and all clinical treatment beyond basic first aid belongs to qualified medical staff and is certified in person.

This is the knowledge layer; the practical detail is confirmed by the College's medical staff and follows current internationally recognised practice. By the end you will be able to explain how the carer's mindset shifts when evacuation is delayed, reassess a casualty continuously over hours, protect them from the environment and above all from cold, manage hydration and comfort safely, keep records on a casualty card, contribute to the evacuation plan, sustain your own endurance, and state the firm limits of buddy-level care.

Key Terms

Prolonged casualty care: sustaining a casualty over hours rather than minutes when evacuation is delayed, while keeping medical help on the way.
Continuous reassessment: repeatedly going round the casualty in the same order, airway, breathing, circulation, warmth, comfort, because their state changes over time.
Lethal triad: the way cold, poor clotting, and acid build-up feed one another in a badly hurt casualty, each making the others worse; in plain terms, a cold casualty bleeds more, and a bleeding casualty grows colder and sicker.
Nothing by mouth: the rule that a casualty who is drowsy, may need surgery, or could deteriorate is given nothing to eat or drink, because it is unsafe.
Pressure care: turning and supporting a casualty who must lie still for a long time, to protect the skin and ease discomfort.
Casualty card: a simple written record of the time, what was found, what was done, and regular observations, used for the handover.
Carer's endurance: the deliberate care of the first-aider's own food, water, warmth, and relief, so the carer does not become a second casualty.

The shift in mindset: from treating fast to sustaining over time

When help is minutes away, speed is everything: control the immediate threat to life and hand over. When help is hours away, speed alone is not enough, because there is no one to hand over to yet. The task becomes endurance. You hold the casualty in the best state you can, steady and protected, for as long as it takes, while you work to bring help nearer.

This is a change of posture, not of technique. The MARCH sequence and the ABCDE assessment still come first and still in the same order. What is added is the discipline of doing them over and over, and of guarding everything a long wait threatens: warmth, fluid, the skin, the spirit. Everything that was a single action in a fast evacuation becomes a sustained task in a slow one. One MARCH becomes MARCH again and again. Warmth becomes constant labour. Success is no longer "handed over alive" but "held steady until help reaches you". The casualty who would have done well with a fast evacuation can still do well with a slow one, if the person beside them refuses to let their condition drift.

Continuous reassessment: going round the casualty again and again

A casualty's state is not fixed. Over hours a quiet airway can obstruct, breathing can tire, a dressing can soak through, shock can deepen, and a warm casualty can grow dangerously cold. The single most important habit in prolonged care is therefore continuous reassessment: going round the casualty in the same order, again and again, on a regular rhythm. Each round, check that the airway is clear, that breathing is present and not labouring, that bleeding is still controlled and the casualty not slipping into shock, that they are warm and dry, and that they are as comfortable and reassured as you can make them. Trends matter more than single readings: a casualty slowly becoming drowsier, paler, or faster of breath is telling you something a single check would miss.

Make the round a fixed drill, in the MARCH and ABCDE order, so a tired mind does not skip a step, and ask each check as a question against the last round's answer. That is what turns a glance into a true reassessment. Read a stable casualty about every fifteen minutes, and one who is changing far more often, every few minutes if you must. Steadiness earns the right to lengthen the interval; any change is a duty to shorten it. The signs are the AVPU scale and the simple ones of Lesson 05, only now tracked across hours rather than minutes, with the card holding the line. Write down what you find each round, and never assume that because all was well an hour ago all is well now.

Protecting the casualty from the environment

Over a long wait, the environment becomes a first priority, ranking alongside the wound itself. Of all the environmental dangers, cold is the greatest, and it is treacherous because it works slowly. A casualty lies still, often wet, frequently losing blood, and the ground draws the heat out of them. Cold is not merely uncomfortable: it worsens bleeding, because cold blood clots poorly, and it deepens shock. A casualty allowed to get cold can deteriorate badly even when the original wound is under control.

So keep the casualty warm and dry and off the cold ground. Heat is lost faster from below than people expect, so insulate from beneath first, with whatever you have, a roll-mat, a poncho, dry vegetation, packs; then cover and wrap above, shelter from wind and rain, and protect the head, which loses heat fast. The insulation beneath comes before the wrapping above, the covered head, and the windbreak. In a hot or exposed setting the same principle of protection applies the other way: shade, loosen, cool, and prevent overheating. The Cold-Weather Operations and Survival course treats this danger and the building of shelter in full; here the lesson is simply that letting a casualty get cold is one of the commonest and most avoidable ways a long wait turns fatal.

Name the danger plainly so you respect it: the lethal triad. In a badly hurt casualty three things feed one another in a vicious circle. Cold makes the blood clot poorly, so bleeding worsens; the bleeding loses warmth and the means to carry oxygen, so the casualty grows colder and the body's chemistry turns sour; and that, in turn, makes the blood clot worse still. A casualty can slide round it even with the wound under a dressing. You cannot treat the chemistry, which is hospital work, but you can break into the circle at the one point a first-aider owns: warmth. Keeping a casualty warm over a long wait is not comfort care; it is bleeding care and shock care, and may be the most useful thing you do all day.

Two cautions go with the warming. Warm gently; do not drive heat into a cold casualty with a fierce fire or scalding bottles against the skin, which can burn and do harm, exactly as the cold-injury teaching in Lesson 06 set out. And warmth is a task you never finish: insulation works loose and the casualty's own heat-making fails as they tire, so warmth, like the round itself, is something you keep returning to until help arrives.

Positioning, dressings, hydration, and comfort over time

Several practical tasks recur through a long wait. None is advanced; all matter.

Positioning and pressure care. A casualty held in one position for hours grows stiff and sore, and the skin over pressure points can break down. Where their injuries allow, ease and re-settle them gently, support the limbs, pad bony points, and turn them a little from time to time, keeping any injured part supported and still. Where there is a risk of spinal injury, keep the body in line and do not turn the casualty except as a trained team, exactly as Lesson 07 set out.
Wound and dressing care. Check dressings on each round to confirm bleeding is still controlled and nothing has soaked through. The guiding rule is do not disturb what has clotted: a dressing that is holding is left alone; reinforce over the top rather than peel back a dressing and restart a bleed. Keep wounds covered and as clean as the conditions allow.
Hydration and comfort. A long wait brings thirst, but fluids by mouth can be dangerous. Give small sips of water only if the casualty is fully awake, able to swallow, and has no serious abdominal wound. The overriding rule is nothing by mouth if the casualty is drowsy, may need surgery, or could deteriorate, because fluid given to such a casualty can be inhaled or can complicate an operation. When in doubt, give nothing and keep asking for medical advice. Hygiene matters too, of the casualty and of your own hands; the Field Health, Hygiene and Sanitation course covers the hydration and hygiene of a casualty held for hours.

Each repays a closer look, because over hours the detail is where harm is done or avoided. On positioning and pressure care, two clocks run at once: the comfort clock, easing the casualty out of needless pain, and the skin clock, by which an unmoving body silently presses the life out of the skin over heel, hip, shoulder, and the base of the spine. Shift the weight a little every half-hour or so, and keep the skin off folds, buckles, and stones. A conscious casualty with no spinal concern and easy breathing is often most comfortable on their side, which also keeps the airway clear if they tire or are sick. Where there is any spinal risk, the rule from Lesson 07 overrides comfort.

On wounds and dressings, the long wait adds infection to bleeding, but the answer is patience, not interference. A clot is the casualty's own fragile repair; every time a dressing is peeled back to "have a look", a healing wound is reopened and a stopped bleed can restart. So a holding dressing is left alone, only watched and reinforced. A tourniquet, once on, stays on; you do not loosen it in the field, and you write its time on the card and on the casualty where it can be seen.

On hydration, understand the safe rule, do not just memorise it. The danger is twofold. A drowsy casualty cannot protect their own airway, so water given to them can go into the lungs instead of the stomach. And a casualty who may need surgery is safer with an empty stomach, because stomach contents can come back up and be inhaled while they are put to sleep for an operation. The gate is narrow, and the instant any part of it fails the answer is nothing by mouth: moisten dry lips with a damp cloth instead, note it on the card, and keep asking for advice. Here doing less is doing better.

   FLUIDS BY MOUTH: THE GATE
   GIVE small sips of plain water ONLY when ALL THREE are true:
       [ ] Fully awake and staying awake
       [ ] Able to swallow safely on their own
       [ ] No serious wound to the abdomen, and unlikely to need surgery
   NOTHING BY MOUTH if ANY is true:
       drowsy or fading  /  may need an operation  /  could deteriorate
   When in doubt: give NOTHING, wet the lips only, and ask for medical advice.

Pain, reassurance, and dignity over a long wait

Buddy-level care offers little for pain beyond comfort, and over hours that comfort does a great deal. A frightened casualty held far from help is fighting fear as much as injury, and fear of its own makes the body worse. Your calm presence is a real treatment. Tell the casualty plainly and honestly what is happening and that help is coming; keep talking to them, use their name, and stay where they can see you. Position them as comfortably as their wounds allow, keep them warm, loosen what constricts, and protect their dignity and privacy throughout. This is the psychological first aid of Lesson 09 stretched across hours: steady, patient, present. Never make a promise you cannot keep, but never leave a casualty to lie alone and afraid when a quiet voice beside them costs nothing and steadies them greatly.

The Look, Listen, Link pattern of Lesson 09 becomes something you do again and again. Answer questions truthfully, including "how long?", even when the honest answer is "I do not know exactly, but help is coming and I am staying with you." Mark the small good signs aloud: "the cloud is lifting", "your breathing is steady". Guard dignity as fiercely as warmth: cover and screen the casualty, and manage the indignities of a long wait, soiling, sickness, exposure, without fuss or comment, as you would wish done for you. Hold one line for yourself: this care is owed by need alone, the same to a stranger as to one of your own, and the long watch is where that promise is tested, and kept.

Keeping records: the casualty card

Memory fails over hours, especially a tired memory under stress, and the medical staff who eventually receive the casualty will need to know not just the present state but how it changed. So keep a casualty card: a simple written record of the time, what you found, what you did, and your regular observations. Record the level of response, the breathing, the colour, and the pulse if you can take one, at each round, with the time beside it. This card is the backbone of a clean handover; it turns a long, lonely watch into a clear picture the medical chain can act on at once. It feeds straight into the MIST handover and, where evacuation is requested, the casualty report and nine-line request taught in the Signals and Field Communication course. A clean, simple monitoring card is enough:

CASUALTY CARD
"Name / unit":        ...........................
"Time found":         ....:....   "Mechanism": .................
"Injuries found":     ...........................................
"Treatment given":    .................  "Tourniquet time": ....:....
"Allergies / meds / known history": .............................

OBSERVATIONS (repeat each round)
"Time"  "Response (A/V/P/U)"  "Breathing"  "Colour"  "Pulse"  "Warm/dry?"  "Notes"
....:.. .................... ........... ........ ....... ........... ......
....:.. .................... ........... ........ ....... ........... ......
....:.. .................... ........... ........ ....... ........... ......

Three habits make the card do its work. First, write at the time, not from memory afterwards; a line entered the moment you read it is worth more than a page reconstructed an hour later, and a column of times reveals a trend at a glance. Second, write the bad news as plainly as the good; a card recording a casualty growing drowsier tells the receiving staff exactly where to look, while a tidy card that hides the slide helps no one. Third, keep it with the casualty up the chain of care; when the lift comes you read it across as the spine of your MIST handover, then hand the card itself over so nothing is lost in the noise of an arrival. The card and the casualty report are two faces of one discipline: the card is the record at the casualty's side, the casualty report the structured request sent on the net, both so that someone who cannot see what you see can act on it without delay.

Planning the evacuation and sustaining your own endurance

While you sustain the casualty, the evacuation must also be worked, and worked as a running problem, not a single message, because over hours the answer changes. Get medical help on the way: send the casualty report early, give the location and the casualty's state, and keep the receiving end updated as things change, using the means and formats of the Signals and Field Communication course. Keep the net warm, and ask, as conditions shift, whether a different way out has opened, a track cleared, a cloud lifted, a tide turned.

Think the route through: the ground, the weather window, the safest way out, drawing on the Navigation and Fieldcraft course, which also covers reaching and signalling for a casualty in remote country. A way fit for a walker may be impossible for a stretcher. Pass the location to the precision that course teaches, an eight-figure grid for a found casualty, and where a helicopter or boat may come, think how it will find you and where it can safely close. Then ready the casualty so that when transport arrives there is no fumbling: warm, dressed, recorded, the route to the pick-up reconnoitred, and the carrying party briefed on one voice and a counted lift. Minutes spent readying casualty and route while you wait, the extraction does not spend later, and on hard ground those minutes are the casualty's.

You must also look after yourself. Sustaining a casualty for hours, in cold or heat, alone or in a small team, is exhausting, and a carer who collapses helps no one and becomes a second casualty for others to manage. Tend your own basics as Lesson 09 taught: eat, drink, stay warm and dry, and rest when you can. Above all, be relieved: where there is more than one of you, take turns at the casualty's side so that no one is worn down to the point of error. A carer who is cold, starved, and exhausted makes poor decisions, misses the trend on the card, and is the likeliest person on the hillside to become the next casualty. So watch your team-mates for the quiet signs of cold and exhaustion as you watch the casualty for shock, and say so when you reach your own limit; admitting it early is the disciplined act. The long watch is endured, not sprinted, and the carer who paces it is the one still clear-headed when the casualty needs them most.

The firm limits of buddy-level care

A long wait can tempt a first-aider to attempt more than they should, simply because no one with greater skill has arrived. Resist it. The limits of Lesson 08 do not loosen because help is far away; if anything they matter more, because there is no one beside you to correct a mistake. The soldier in prolonged care sustains and summons. You keep the casualty alive, warm, hydrated within the safe rule, comfortable, and recorded, and you keep medical help coming as fast as the ground and weather permit. You do not undertake clinical procedures beyond basic first aid: these are taught and certified in person, under qualified medical supervision, and they are beyond the scope of buddy aid. The measure of excellent prolonged care is not how much you did to the casualty, but how well you held them, unharmed by your own hand, until those who can do more arrive.

The skills beyond basic first aid you may be tempted by, advancing an airway by instrument, putting fluids into a vein, giving medicines, releasing a tourniquet, are not withheld to keep you in your place. They are withheld because, done by an untrained hand without the means to judge what follows, they harm more casualties than they help, and on a long wait there is no one beside you to catch the error before it kills. The right response is the one this course teaches throughout: do the simple things superbly and without ceasing. A casualty so held for many hours has been served as well as buddy aid can serve them, and far better than by a well-meant procedure beyond skill. Sustain, and summon: on the long watch that is the whole of the duty, and it is enough.

In Practice: A Delayed Lift Above the Valley

A relief party reaches a fallen herder on high ground above a flooded valley track. He has a broken leg and is cold, soaked, and frightened. Low cloud has grounded the helicopter and the road below is washed out, so the lift will be hours, not minutes. You splint and support the leg, check it is not bleeding heavily, and leave the holding dressing undisturbed. Then protection from the cold becomes your first long task: you get him off the wet ground onto packs and a roll-mat, wrap and shelter him, and cover his head. You go round him on a regular rhythm, response, breathing, colour, pulse, warmth, writing each round on the casualty card. He is fully awake and has no belly wound, so you allow small sips of water; later, as he tires and grows drowsy, you stop all fluids and keep asking for advice over the radio. You sit with him, use his name, and tell him honestly that the cloud is lifting and help is coming. Your partner shares the watch so neither of you is worn out. When the lift arrives, you hand over a warm, steady, fully documented casualty and a clear MIST report. He lives because, for six cold hours, someone refused to let his condition drift while help fought its way to him.

Notice where the lesson lives. The leg was the obvious injury, but the cold was the real enemy, and breaking the lethal triad at its one reachable point kept a broken leg from becoming a dying man. The round never lapsed, the fluids were withdrawn the instant he tired, the watch was shared so neither carer became the second casualty, and nothing was attempted beyond buddy aid. The simple things, done superbly and without ceasing, held the long watch.

Check Your Understanding

How does the carer's mindset change when evacuation is delayed from minutes to hours, and why does continuous reassessment become the most important habit? Give two things you would check on each round.
Why is keeping a casualty warm and dry treated as a first priority over a long wait? What does cold do to bleeding and to shock, and what is the "lethal triad" in plain terms?
State the rule for giving fluids by mouth over a long wait, and the rule for when a casualty must have nothing by mouth. Why is the second rule so important?

Reflection (write a short paragraph): Prolonged care asks little cleverness and much patience: hours of going round a casualty, keeping them warm, writing down numbers, and sitting with a frightened person while you wait. Why might this quiet endurance be harder than the dramatic first minutes, and what does it ask of your character and of the Army's promise that care is owed to everyone by need alone? What will you hold to, in yourself, on the long watch?

Summary

When evacuation is delayed by distance, weather, or a cut road, the mindset shifts from "treat and evacuate fast" to "sustain over time", while keeping medical help on the way; the MARCH and ABCDE drills are unchanged but repeated.
Reassess continuously, going round the casualty again and again, airway, breathing, circulation, warmth, comfort, on a fixed rhythm, about every fifteen minutes when steady and far more often when changing, because their state shifts over hours and trends matter more than single readings.
Protecting the casualty from the environment, above all keeping them warm, dry, and off the cold ground, is a first priority, because cold worsens bleeding and deepens shock; warmth is the one point at which a first-aider can break the lethal triad. Manage positioning, pressure care, and dressings gently, and never disturb what has clotted.
Give small sips of plain water only to a casualty who is fully awake, able to swallow, and without a serious abdominal wound; give nothing by mouth if they are drowsy, may need surgery, or could deteriorate. Keep a casualty card written at the time, work the evacuation as a running problem, and sustain your own food, water, warmth, and relief so you do not become a second casualty.
The soldier sustains and summons: you do the simple things superbly, and all clinical treatment beyond basic first aid is given by qualified medical staff and certified in person.

Prolonged and Austere Casualty Care
