Tourniquet Application
Definition
Hemorrhage control device applied 2-3 inches proximal to wound when direct pressure fails.
Exam Focus Areas
On the Nremt Emt, Nremt Paramedic exam(s), questions about tourniquet application typically test:
- Correct medication selection, dosing, and route of administration
- Appropriate transport decisions and hospital notification criteria
- Recognition of signs and symptoms requiring immediate intervention
Historical Context
The modern EMS system in the United States traces to the 1966 "Accidental Death and Disability" white paper (NAS/NRC). Understanding of tourniquet application 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.
Assessment Techniques
Assessment techniques for tourniquet application:
- OPQRST
- Components: Onset, Provocation, Quality, Radiation, Severity, Time. Scoring: Pain assessment mnemonic
- SAMPLE
- Components: Signs/symptoms, Allergies, Medications, Past history, Last intake, Events. Scoring: Mnemonic for patient history gathering
Clinical Significance
In prehospital care, understanding tourniquet application 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: midazolam at 2-5mg IV/IM, 0.2mg/kg IN, indicated for Seizures, sedation.
Why It Matters
Tourniquet indications and placement tested on EMT exam.
