Steam-line failure: 27% scald with nine hours to hospital

The 12-man crew of a 4,500 GT offshore supply vessel is on passage 90 nautical miles off Bonny when a steam-line flange fails in the engine room at 0310. An oiler, 38 years old and about 80 kg, takes the full blast across the front of his chest and abdomen and down his right arm before the isolation valve is shut. He is conscious and in severe pain. The skin over his anterior chest and abdomen and the whole of his right arm is red and blistered, with patchy white, leathery, painless areas near the shoulder. The engine room is hot and humid. The nearest suitable hospital is about nine hours away at 12 knots, there is no doctor on board, and you are the designated first aider with the ship's medical chest. The master is waiting for your assessment so he can decide whether to divert. A steward has already brought a bucket of iced water from the galley.

1. Estimate the extent and depth of the burn, and explain why that estimate changes what you do and what you advise the master.

Extent. Use the rule of nines: anterior trunk (chest plus abdomen) is 18% and a whole arm is 9%, giving roughly 27% total body surface area. Count only skin that is actually burned; do not double-count the white patches.

Depth. Red, blistered, painful skin is superficial partial thickness. The white, leathery, painless areas near the shoulder suggest deep partial or full-thickness injury, which is consistent with a high-pressure steam blast.

Why it matters. In an adult, burns above roughly 15-20% TBSA are major injuries: capillary leak causes hypovolaemic shock over the first hours and fluid resuscitation is needed. For an 80 kg man at 27%, the Parkland estimate is 4 x 80 x 27 = about 8,600 mL in 24 hours, half of it in the first 8 hours. That cannot be given orally and cannot wait nine hours, so this is a strong argument to divert or request a MEDEVAC rather than press on. The size also governs your cooling decision: flooding 27% of a hot body with cold water will cause shivering and hypothermia, which deepens shock. Cool only what is practical, for up to 20 minutes, and keep the rest of him covered and warm toward the end.

2. Set out your first aid for the burn itself, including what you must not do and why the bucket of iced water is refused.

Sequence first: confirm the steam line is isolated, then check response, airway and breathing. Give 100% oxygen if he tolerates it. Do not let him walk to the cabin; treat him where he is once the space is safe.

Cooling. Copious cool running water is the best first aid, ideally within the first three hours. With 27% TBSA and a hot environment, limit it to about 10 minutes and stop if he starts to shiver. No ice and no iced water: ice causes intense vasoconstriction, deepens the tissue damage and drops core temperature, and it does not sterilise anything.

Do not: burst blisters, apply butter, oil, toothpaste or antiseptic creams, or peel away clothing stuck to the burn. Cut around stuck fabric. Remove rings and a watch from the burned arm before swelling begins.

Cover. Lay cling film in sheets along the limb rather than wrapping it circumferentially, or use a clean non-fluffy dressing. Circumferential wrapping can act as a tourniquet as the limb swells.

Then: elevate the burned arm, keep him warm with blankets, keep him nil by mouth because vomiting and later surgery are likely, treat pain under radio medical advice, and record the time of injury and every intervention.

3. What would you monitor, how would you position him, and what findings would push you to demand immediate evacuation?

Monitor every 15 minutes: consciousness (AVPU), respiratory rate and effort, pulse rate and volume, blood pressure if a cuff is available, capillary refill, and urine output if he can be catheterised or at least asked to pass urine into a bottle. Look for the classic shock picture: restlessness, thirst, pallor, cold clammy skin, a rising thready pulse and falling blood pressure. He is already pale and clammy with a pulse of 100, which is early compensation, not reassurance.

Position him lying flat with the legs elevated if his breathing allows; if the chest burn makes breathing easier sitting up, let him sit and accept the compromise. Reassess constantly.

Red flags demanding immediate radio medical advice and evacuation: laboured or noisy breathing, a rising respiratory rate, falling oxygen saturation, a circumferential or near-circumferential burn of the chest limiting expansion, hoarseness or soot suggesting inhalation, falling level of consciousness, urine output dropping below about 0.5 mL/kg/hour, or a pulse that climbs while blood pressure falls. Convey to the doctor the age, weight, TBSA, depth, time of burn, pulse, respiratory rate, oxygen saturation and urine output, and record everything with times for the handover.
