Hydrocarbon, caustic and household chemical exposure
Also known as Petroleum distillate ingestion in children · Hydrocarbon aspiration pneumonitis · Caustic ingestion in children · Alkali and acid corrosive ingestion · Household cleaner and detergent exposure
A fellowship approach to paediatric hydrocarbon, caustic and household chemical exposure. First identify the product. A hydrocarbon (petroleum distillate) threatens by aspiration, so never induce emesis, never lavage, and observe for six hours. A caustic agent threatens by corrosive injury, so keep nil by mouth, never neutralise, and arrange early endoscopy within twenty-four hours. Corticosteroids and prophylactic antibiotics are not routine. Call the poisons information centre early and tailor every rule to the product and the local protocol.

Red flags
- Never induce emesis in a hydrocarbon or caustic ingestion: it converts a contained exposure into aspiration or repeated mucosal injury
- Never perform gastric lavage for a hydrocarbon: the risk is aspiration pneumonitis, not systemic absorption
- Never neutralise a caustic agent: the exothermic reaction and gas production worsen the burn
- A well-looking child after a hydrocarbon ingestion can deteriorate at six hours: observe for the full period before discharge
- A normal chest X-ray early in hydrocarbon pneumonitis does not exclude evolving lung injury; radiographic changes lag behind symptoms
- The absence of oral or oropharyngeal burns does not exclude a significant oesophageal or gastric caustic injury
- Liquid laundry detergent capsules and concentrated dishwasher tablets carry disproportionate risk of severe injury and airway compromise

Overview & Definition
Household chemical exposure in a child is one of the most common presentations to paediatric emergency care, and the single most important skill is not memorising antidotes but reading the situation by the product. The product decides the dominant threat, decontamination rule, observation period and the need for endoscopy. A child who swallowed lamp oil is not the same as a child who swallowed drain cleaner, and a child who swallowed low-concentration household bleach is not the same as either. Grouping them as "poisoning" without separating the chemical class is the first and most dangerous error. [1] [6]
Three chemical classes account for almost all serious paediatric household exposure. Hydrocarbons are petroleum distillates (petrol, kerosene, lamp oil, lighter fluid, mineral spirits, turpentine) and some volatile solvents; their danger is aspiration, because their low viscosity and low surface tension let them spread into the alveoli and cause a chemical pneumonitis. Caustic agents are strong alkalis (sodium and potassium hydroxide in drain cleaners, oven cleaners, dishwasher tablets) and strong acids (sulfuric, hydrochloric, sulfamic acid in toilet bowl cleaners, battery acid, rust removers); their danger is corrosive injury of the gastrointestinal tract. The third class, low-concentration household products (household bleach, detergents, disinfectants), is usually only irritant and rarely causes serious injury unless the agent is concentrated, a capsule formulation, or a large volume is taken. [1] [2]
The shared principle that runs through every pathway is restraint. The interventions that are contraindicated here are as important as the ones that are indicated. Induced emesis, gastric lavage for hydrocarbons, and neutralisation of caustics each convert a contained exposure into a worse one. The modern approach is therefore supportive and product-specific: secure the airway and breathing, avoid the harmful reflexes of decontamination, observe or endoscope as the product demands, and call the poisons information centre early to confirm the product-specific rule.
