Pressure cooker scald on a rainy night
At 7 p.m. in a home in Darbhanga, 11-year-old Rahul lifts the lid of a pressure cooker that has not cooled; steam and hot dal spill over his right forearm and the front of his shirt. His forearm is red within minutes and two blisters the size of a rupee coin appear over an area about the size of his own palm; the shirt front is stuck to the skin over his chest. His mother rubs toothpaste on the arm and covers it with cotton wool, then says they should wait till morning because the doctor's clinic is 12 km away and it is raining. The grandmother wants to apply coconut oil and open the blisters with a needle. Rahul is shivering and says he feels sick. The family owns a first-aid box with gauze, bandage, an antiseptic cream and ORS.
1. Identify the errors already made in the first aid and the reasoning behind each error.

1. Toothpaste on the burn. It is not sterile, it is abrasive, and it contains menthol, fluoride and other chemicals that irritate damaged skin. It has no cooling or antiseptic role and it hides the wound from the doctor. Worse, it has to be scrubbed off later, which removes tissue.
2. Cotton wool over it. Cotton fibres shed and stick into the raw surface; when the dressing is changed, fibres and skin come away together. Only clean, non-fluffy material belongs on a burn.
3. Coconut oil (the grandmother's plan). Oil holds heat in the tissue and keeps the burn cooking, seals in bacteria under an airtight film, and makes later assessment impossible. The old rule is simple: nothing on a burn except cool water and a clean cover.
4. Opening the blisters with a needle. The blister roof is a sterile biological dressing. Puncturing it introduces infection and turns a partial-thickness burn into an open wound.
5. Waiting till morning. This decision is the most serious. There is a burn over the chest in a child, a stuck shirt suggesting deeper injury, and systemic signs - shivering and nausea - which may reflect pain, heat loss or developing shock.
What was right: nothing harmful has been done to the airway, and the family does have gauze, bandage and ORS at hand, which can be used correctly.
2. Give the correct sequence of action from the moment of the injury, including what to do about the shirt stuck to the chest and the blisters.

1. Stop the burning. Move Rahul away from the cooker and the steam. Do not let him run around; keep him still.
2. Cool with running water. Hold the forearm under cool, gently running tap water for about 20 minutes. Do not use ice, ice water or a freezer pack - ice causes further tissue damage. Cooling reduces pain and limits the depth of the burn.
3. The stuck shirt. Do not pull it off. Cut the shirt away around the stuck portion with scissors, leaving the adherent cloth in place. Pulling would tear skin and deepen the injury.
4. Remove rings, bangles, watch from the burnt arm before swelling begins.
5. Do not touch the blisters. Leave them intact; cover the area loosely with clean non-fluffy cloth, or cling film laid on, not wrapped tight. Gauze from the box is acceptable if it is clean and applied without pressure.
6. Keep him warm and calm. Cover the unburnt parts with a clean sheet. Shivering after cooling is expected, but it must not be ignored.
7. Give small sips of ORS if he is fully conscious and not vomiting, to replace fluid loss.
8. No toothpaste, oil, turmeric, ash, ink or antiseptic cream on the burn.
9. Travel while arranging care. Do not delay transport waiting for a perfect dressing; a clean cloth and a moving vehicle are enough.
3. Decide whether Rahul must be taken to hospital tonight, and justify the decision using the features in the case. Add prevention advice for the household.

Yes - he must be seen tonight.
Area estimate. In a child, the palm with fingers equals about 1% of body surface. The forearm burn alone is around 1% on this rough palm measure, but the shirt is stuck to the chest, which means the chest is also burnt; chest and neck burns add several per cent. A scald of this pattern in a child warrants medical review whatever the exact figure.
Site. Chest and forearm are not trivial sites. Burns to the chest, neck, face, hands, feet or over a joint, and any burn that circles a limb, are referral criteria.
Depth and mechanism. Scalding by dal under pressure is hotter than boiling water and sticky, so contact time is longer; the stuck shirt suggests a deeper burn. Blistering indicates at least partial-thickness injury.
Systemic signs. Shivering and nausea in a child after a burn may indicate pain, heat loss, or early shock. These are the features that make 'wait till morning' unsafe, rain or no rain.
Prevention to advise:
- Let the cooker cool completely, or hold it under running water, before opening; open the lid away from the face.
- Keep children out of the kitchen while pressure cooking.
- Cook on the back burners and turn handles inward.
- Keep a burn kit and the hospital number in the kitchen, not in a locked cupboard.
