Study Notes
Clinical Toxicology - Initial Evaluation & Management of Poisoned Patients
- Clinical toxicology focuses on the effects of drugs and chemicals on humans and other animals, specifically drug overdoses and poisonings. It involves determining the substance and its amount in the body.
- Clinical toxicology overlaps with other fields like biochemistry, pharmacology, and pathology.
- All poisoned patients should be managed as if they have a life-threatening intoxication, even if they appear normal.
- The initial approach to a poisoned patient should be the same, regardless of the ingested toxin. This approach is termed routine poison management.
- Common poisonings include exposures to household cleaning products, pesticides, and most importantly prescription and over-the-counter medications.
- Crucial strategies include promptly treating the patient (not the poison), establishing supportive therapy for respiration and circulation, and meticulously tracking vital signs and reflexes to assess intoxication progress.
Approach to the Poisoned Patient (ABCDEs)
- Airway: Keep airways patent and remove any obstructions. Loss of airway reflexes is a major cause of death. Potential obstructions include flaccid tongue, or aspiration of gastric contents.
- Breathing: Evaluate respiratory rate and oxygen saturation. If no monitor is available but the patient has a high respiratory rate, supplemental oxygen should be considered.
- Circulation: Quickly assess vital signs (blood pressure, pulse rate, rhythm) and hydration status. Secure venous access. Draw blood for routine tests. Begin intravenous fluids, using normal saline or another isotonic solution if the patient is hypotensive.
- Disability (Neurological): Evaluate level of consciousness. If the patient has seizures, check blood sugar. If the blood sugar is less than 72 mg/dL, administer 50 mL of 50% dextrose intravenously. Treat toxic seizures with IV benzodiazepines; refractory seizures may need barbiturates.
- Exposure (temperature): Consider toxic syndromes associated with hyperthermia, as high drug levels can elevate body temperature significantly.
