Prolonged Field Care Decisions

Almost all emergency training assumes an arrival. Resuscitate, package, hand over — and the timeline is measured in tens of minutes. On a vessel mid-ocean, on an offshore installation in bad weather, on an expedition, or in a humanitarian setting where the referral hospital is a day's drive away, that assumption fails, and it fails in a way that reorders your priorities rather than simply making them harder.

The shift is from stabilise-and-transfer to sustain. Different problems dominate, different skills matter, and several things that are correct in a resus bay become wrong over twelve hours.

If you want to rehearse a long hold, run an extended-care case in the app.

What reorders when the clock gets longer

Six shifts, roughly in order of how much trouble they cause when missed.

Consumables become clocks. Oxygen, batteries, fluids, drugs, dressings, and your own team's alertness. Each one has a rate of consumption and a remaining quantity, and the ratio is a number of hours. Calculating those hours early is not administration — it is the constraint that determines what management is even possible. A treatment plan that outlasts your oxygen is not a plan.

The basics start determining outcome. Position, pressure areas, temperature, eyes, mouth, bladder, bowels, skin. Over twenty minutes these are irrelevant. Over twenty hours they are the difference between a patient who arrives in reasonable condition and one who arrives with complications you caused. This is nursing care, it is the highest-yield activity available to you over a long hold, and it is what an emergency-trained clinician is least accustomed to prioritising.

Documentation becomes the clinical record of a trend. With a long hold, the trajectory over hours is the most important clinical information in existence, and it exists only if it was written down. Timed observations, timed interventions, timed responses. Nobody's memory produces a usable twelve-hour trend.

Reversibility becomes a criterion. In a hospital you can escalate an intervention because someone will manage the consequences shortly. Over a long hold, every intervention you start you also have to maintain, monitor and eventually discontinue. Before starting something, ask what maintaining it for eight hours requires and whether you have that.

Your own team becomes a limited resource. Two people cannot provide continuous care indefinitely. Fatigue management is a clinical plan: who rests when, and who is genuinely capable of taking over. A rota written at hour one is far better than a collapse at hour nine.

The patient becomes a person with hours of consciousness to fill. Explanation, reassurance, pain and nausea control, and being told what is happening. Over a long hold this is not soft care; a frightened patient in pain is harder to assess, harder to manage and physiologically worse off.

Decisions to make in the first hour

Early decisions constrain everything afterwards, and several of them are much easier to make at hour one than at hour six.

1. Establish the real evacuation timeline, with a range. Not "they are coming" — earliest and latest plausible arrival, and what would change it. Ask the operational people directly, and ask what the deadline is on each option. Weather windows and daylight limits are clinical constraints.
2. Calculate your consumable hours. Oxygen especially. Do the arithmetic, write the number on the wall, and recalculate it when the rate changes.
3. Make the remote advice call early. Before you need a decision, while the picture is still incomplete. Establishing the clinical relationship and getting agreement on a plan and its triggers is much easier at hour one than mid-crisis, and it gives the person advising you a baseline to compare against later.
4. Choose your monitoring interval and your triggers, and write them down. Both the interval and the specific findings that would change your management. Then set an actual alarm, because over hours, intervals drift.
5. Set up the space. Where the patient will be for the whole hold, not where they happen to be now. Access to the head and both sides, equipment within reach, lighting, temperature, and somewhere for a second person to work.
6. Write the fatigue rota. Including you. The clinician who works nine hours straight and then makes the transfer decision is the risk in the system.
7. Decide what you will not do. Interventions that are beyond your competence, unmaintainable with your resources, or irreversible. Naming them in advance, in writing, prevents them being reached for at hour seven by a tired version of you.

Managing the middle hours

The dangerous part of a long hold is not the beginning or the end. It is the plateau, where nothing much is changing, vigilance decays, and the trend that matters develops slowly enough to be invisible from one check to the next.

Structure defeats drift. Run a fixed cycle: full observations, structured reassessment of the primary survey, the basic care items, consumable check, documentation. Same order every time. A written cycle sheet is worth more at hour eight than any amount of good intention.

Compare against the record, not against your impression. At each cycle, read the observations from four hours ago rather than the last set. Slow deterioration is invisible from adjacent readings and obvious across a four-hour gap.

Re-examine from the beginning periodically. Not a check of the problem you know about — a full reassessment. New problems appear over long holds, and they appear in places you have stopped looking.

Keep the remote clinician updated on the trend, not just on events. A short scheduled update, even one saying nothing has changed, maintains a shared picture and makes the eventual decision faster.

Reassess the plan against the clock. Every few hours, ask whether the plan still fits the remaining time and remaining resources. Plans made at hour one against an eight-hour estimate need revisiting when the estimate becomes eighteen.

The conversation about limits

Extended care in a remote setting sometimes reaches a point where the available treatment cannot achieve what the patient needs. That is a genuinely difficult situation, made worse by being unexpected, and it is worth having thought about beforehand.

Three principles that hold up. Involve remote medical direction in the reasoning rather than presenting a conclusion — a decision reached jointly with a senior clinician is both better and more defensible. Document the clinical reasoning contemporaneously, including what was available, what was tried and what was discussed. And be honest with the patient and, where appropriate, with their family, within what you know.

The team also needs attention here. People who have provided intensive care to one patient for many hours, in a place with no relief and no separation between the clinical space and the living space, are affected by the outcome in a way that hospital staff usually are not. Planning a debrief and knowing what support exists is part of the clinical plan, not an afterthought.

Preparing before it happens

Almost all of this is preparable, and none of it is preparable during the event.

Know your consumable numbers now. How many hours of oxygen you hold at various delivery rates. How long your monitor runs on battery. How much of each fluid and drug you have. Work these out on a calm day and write them somewhere findable.

Rehearse the long hold, not just the resuscitation. Run a scenario that starts at hour four. Skip the drama entirely and practise the cycle, the recalculation, the update call and the fatigue handover. It is an unglamorous rehearsal and it is the one that matches what you will actually do.

Write the cycle sheet in advance. A single page listing the reassessment cycle, the basic care items and the consumable check. Under fatigue, a page beats recall every time.

Set up your offline references before you deploy or sail. Installation, downloads and account setup need internet access; the situation where you need the reference will not have it. Core training and reference tools are designed to work offline after setup, and setup is a pre-departure task.

Know your remote medical direction pathway cold. Who, how, what number, what the fallback is if the primary route fails, and what information they will ask for. Practise the call once when nothing is happening.
