Primary Survey (ABCDE)

Clinical Significance

In prehospital care, understanding primary survey (abcde) can mean the difference between a positive patient outcome and a critical miss. A construction worker stung by wasps, developing urticaria, stridor, and hypotension. Anaphylaxis: epinephrine 0.3mg IM, IV fluids, diphenhydramine, albuterol for bronchospasm.

Related pharmacology: albuterol at 2.5mg nebulized, can repeat, indicated for Bronchospasm, asthma, COPD.

Related Procedures

Procedures related to primary survey (abcde) in the EMS setting:

1. Trauma assessment: scene safety then MOI then primary survey (XABCDE) then rapid transport then secondary survey en route
2. Stroke recognition: Cincinnati Prehospital Stroke Scale (facial droop, arm drift, speech) then last known well time then transport to stroke center
3. Pediatric weight-based dosing: Broselow tape for length-based weight estimation in emergencies

Documentation

Documentation of primary survey (abcde) in the patient care report (PCR) must include: time of assessment, findings, interventions performed, patient response, and reassessment findings. Use objective, measurable terms like "patient reports 8/10 chest pain" rather than "patient in pain." Document pertinent negatives. All medications administered must include drug name, dose, route, time, and patient response.

Overview

Rapid assessment: Airway, Breathing, Circulation, Disability (neuro), Exposure. Identifies and treats life threats immediately. Primary survey sequence tested on EMT and Paramedic exams.

In prehospital assessment, heart rate reference range: adult 60-100 bpm, pediatric 80-150 bpm (infant), 70-120 bpm (child). Deviations from these norms guide treatment decisions in the field.

Professional Standards

Professional standards for primary survey (abcde) are established by the relevant certification body and regulatory agencies. Certified professionals must demonstrate competency through examination and maintain credentials through continuing education. Scope of practice is defined by state law and facility policy. Never perform tasks outside your authorized scope.
