There are few specific "antidotes", and only relevant if long or delayed transport. It is permissible to follow the instructions on the poisons container, but follow up with Poisons Information Centre. If the information conflicts — Poisons
Information Centre's management takes priority. Watch the A.B.C., these are important.
Inhalation poisoning is potentially dangerous to rescuers. Recognise an environment with continuing contamination and extricate rapidly from a toxic atmosphere.
Protect medical personnel particularly when there may be more than one person appearing affected on a scene. Contact the Clinical Support Paramedic or Duty Manager in the State Operations Centre to advise before entering; consider requesting Special
Operations Paramedics where the environment isn't congruent with the patient(s) clinical presentation.
Agent, dose and time of ingestion should correlate with patient presentation. When the patients mental status allows ask them the history. If altered mental status doesn’t allow then consider the local environment for possible agents.
Agent: What have they been exposed to?
Dose: How much, and by what route?
Time since Ingestion: When did the poisoning occur?
Clinical Features: Consider the potential course of action if the agent known.
Consider consulting The Australian Poisons Information Centre on 131126
Consider corrosive injury if suspected ingestion of alkalis, acids, glyphosate, or paraquat. Patients with significant laryngeal or epiglottic oedema may present with stridor or hoarse voice. More non specific symptoms which may indirectly
affect the airway include nausea and recurrent emesis, haematemisis, dysphagia or drooling.
Repeat vital signs every 10 minutes (5 minutes if patient appears time critical)
Flush contaminated skin and eyes with copious amounts of water.
Do not induce vomiting
Do not try to neutralise alkalis with acids or acids with alkalis
Within first 10 minutes of ingestion of corrosives or acids, it is permissible to try to give 100ml of water in slow sips to dilute the substance, if patient can tolerate this. Discontinue after 10 minutes as there may be penetrating ulcers
