Sedation and Analgesia

Assessment Techniques

Assessment techniques for sedation and analgesia:

Trauma Score

Components: GCS, Systolic BP, Respiratory rate. Scoring: Revised Trauma Score: coded values 0-4, sum correlates with survival probability

Glasgow Coma Scale

Components: Eye opening (1-4), Verbal response (1-5), Motor response (1-6). Scoring: 3-15, 8 or less = severe, 9-12 = moderate, 13-15 = mild

Clinical Significance

In prehospital care, understanding sedation and analgesia can mean the difference between a positive patient outcome and a critical miss. A 65-year-old male presents with crushing substernal chest pain radiating to the left arm, diaphoresis, and nausea. 12-lead shows ST elevation in leads II, III, aVF (inferior MI).

Historical Context

The modern EMS system in the United States traces to the 1966 "Accidental Death and Disability" white paper (NAS/NRC). Understanding of sedation and analgesia has advanced significantly with evidence-based protocols. The NREMT, founded in 1970, standardized certification levels. Current ACLS and PALS guidelines are updated every 5 years by the AHA based on the International Liaison Committee on Resuscitation (ILCOR) evidence review.

Professional Standards

Professional standards for sedation and analgesia 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.

Differential Diagnosis

When assessing sedation and analgesia, use structured assessment tools to differentiate between possible causes:

Cincinnati Stroke Scale: Components: Facial droop, Arm drift, Speech abnormality. Scoring: Any 1 positive = 72% probability of stroke.

APGAR: Components: Appearance, Pulse, Grimace, Activity, Respiration. Scoring: 0-10 at 1 and 5 minutes, under 7 needs intervention.
