Section 17 Flashcards
(40 cards)
What is the primary assessment for a patient with suspected poisoning?
Airway, Breathing, Circulation (ABC), neurological status, and exposure history.
How is the severity of poisoning evaluated?
Based on clinical presentation, toxic substance, amount ingested, and time since exposure.
What are the common routes of toxic exposure?
Ingestion, inhalation, dermal contact, and injection.
What is the purpose of gastric lavage in toxicology?
To remove ingested toxins from the stomach if performed within one hour of ingestion.
How is activated charcoal used in poisoning cases?
It adsorbs toxins in the gastrointestinal tract to prevent absorption.
What are contraindications for activated charcoal?
Airway compromise, ingestion of caustics or hydrocarbons, and risk of aspiration.
What is the role of whole-bowel irrigation in toxicology?
To flush out ingested substances from the gastrointestinal tract, especially for sustained-release or enteric-coated tablets.
What are the symptoms of opioid overdose?
Respiratory depression, pinpoint pupils, and altered mental status.
How is opioid overdose managed?
Administration of naloxone, airway support, and monitoring for recurrence.
What are the clinical features of benzodiazepine overdose?
CNS depression, respiratory depression, hypotension, and ataxia.
How is benzodiazepine overdose treated in emergency settings?
Supportive care, flumazenil administration if indicated, and airway protection.
What are the symptoms of organophosphate poisoning?
Salivation, lacrimation, urination, diarrhea, gastrointestinal distress, and emesis (SLUDGE syndrome).
What is the antidote for organophosphate poisoning?
Atropine and pralidoxime (2-PAM).
How is carbon monoxide poisoning identified?
Headache, dizziness, confusion, and cherry-red skin color.
What is the emergency management for carbon monoxide poisoning?
Administration of 100% oxygen and hyperbaric oxygen therapy if severe.
What are the symptoms of cyanide poisoning?
Altered mental status, seizures, hypotension, and metabolic acidosis.
What is the antidote for cyanide poisoning?
Hydroxocobalamin or sodium thiosulfate.
What are the clinical features of methanol poisoning?
Visual disturbances, metabolic acidosis, and CNS depression.
How is methanol poisoning managed?
Administration of fomepizole or ethanol, and hemodialysis if severe.
What are the symptoms of ethylene glycol poisoning?
Metabolic acidosis, renal failure, and CNS depression.
What is the emergency treatment for ethylene glycol poisoning?
Fomepizole or ethanol therapy and hemodialysis if necessary.
What are the symptoms of iron toxicity?
Nausea, vomiting, abdominal pain, metabolic acidosis, and shock.
How is iron toxicity managed in emergency settings?
Deferoxamine administration and supportive care.
What are the signs of aspirin (salicylate) overdose?
Tinnitus, hyperventilation, metabolic acidosis, and altered mental status.
