Poisoning

NREMT EMTNREMT PARAMEDIC

Definition

Exposure to toxic substances via ingestion, inhalation, injection, or absorption. Treatment based on substance and route.

Patient Communication

Communication about poisoning in the prehospital setting includes: explaining procedures to the patient in simple terms, obtaining informed consent when possible (implied consent for unresponsive patients), providing a calm and reassuring presence, and delivering a structured handoff report (SBAR: Situation, Background, Assessment, Recommendation) to the receiving facility.

Related Procedures

Procedures related to poisoning in the EMS setting:

  1. RSI sequence: preoxygenation then sedation (etomidate 0.3mg/kg or ketamine 2mg/kg) then paralytic (succinylcholine 1.5mg/kg or rocuronium 1mg/kg) then intubation then confirm placement with waveform capnography
  2. Stroke recognition: Cincinnati Prehospital Stroke Scale (facial droop, arm drift, speech) then last known well time then transport to stroke center
  3. AHA ACLS cardiac arrest algorithm: CPR then rhythm check then shock if VF/pVT then epinephrine q3-5min then amiodarone

Safety Considerations

Field safety for poisoning includes scene assessment before patient contact. Ensure BSI (body substance isolation) precautions are in place. PPE selection depends on the mechanism and suspected pathogens. Gloves are the minimum; add mask and eye protection for splash risk, N95 for airborne pathogens.

Never approach a scene involving hazardous materials, violence, or structural instability without proper resources and clearance from incident command.

Workplace Applications

In daily practice, poisoning is applied consistently according to facility protocols and current evidence-based guidelines. Competency is maintained through annual skills validation, continuing education, and quality improvement participation.

Frequently Asked Questions

What equipment is needed for managing poisoning in the field?
For poisoning: AED provides Automated external defibrillator for VF/pVT. BVM provides Bag-valve-mask for manual ventilation. Pulse oximeter provides Measures SpO2 via infrared absorption through capillary bed.
What protocol applies to poisoning in prehospital care?
For poisoning: STEMI protocol: 12-lead ECG within 10 min then aspirin 324mg then NTG if SBP >90 then notify cath lab then transport code 3
What assessment tools help evaluate poisoning?
For poisoning: Trauma Score: evaluates GCS, Systolic BP, Respiratory rate; scoring is Revised Trauma Score: coded values 0-4, sum correlates with survival probability. APGAR: evaluates Appearance, Pulse, Grimace, Activity, Respiration; scoring is 0-10 at 1 and 5 minutes, under 7 needs intervention.
