ED Management
• Primary Survey –ABCde’s (Two minutes)– Airway and C-spine control
– Breathing
– Circulation
– Disability – Neurological exam
– Exposure – Undress and roll
– Finger and Foley
– +/- Nasogastric tube
![Page 16: ED Management of Trauma - Harvard Universitymycourses.med.harvard.edu/ResUps/ME535M.S/pdfs/HMS_1702.pdf · Hospital trauma designations • Level I – Attending emergency physician](https://reader035.vdocument.in/reader035/viewer/2022071001/5fbe76c55aae5217c34ee8bf/html5/thumbnails/16.jpg)
AirwayObserve
Ask a basic question – How are you? What happened?Immedicate interventions –
Clear airway• chin lift• suction• Finger sweep
![Page 17: ED Management of Trauma - Harvard Universitymycourses.med.harvard.edu/ResUps/ME535M.S/pdfs/HMS_1702.pdf · Hospital trauma designations • Level I – Attending emergency physician](https://reader035.vdocument.in/reader035/viewer/2022071001/5fbe76c55aae5217c34ee8bf/html5/thumbnails/17.jpg)
Airway
Protect/establish airway
• Oral or nasopharyngeal airway
• naloxone
• tracheal intubation
• crycothyrotomy
• transtracheal needle (jet) ventilation
![Page 18: ED Management of Trauma - Harvard Universitymycourses.med.harvard.edu/ResUps/ME535M.S/pdfs/HMS_1702.pdf · Hospital trauma designations • Level I – Attending emergency physician](https://reader035.vdocument.in/reader035/viewer/2022071001/5fbe76c55aae5217c34ee8bf/html5/thumbnails/18.jpg)
Breathing
• Evaluate - breath sounds, respiratory rate, pulse ox, chest movement, subcutaneous air
• BVM ventilate with 100% O2
• Check neck for tracheal deviation – look and feel
• Check thorax for asymmetric or paradoxical movements (flail chest) or obvious sucking wound
![Page 19: ED Management of Trauma - Harvard Universitymycourses.med.harvard.edu/ResUps/ME535M.S/pdfs/HMS_1702.pdf · Hospital trauma designations • Level I – Attending emergency physician](https://reader035.vdocument.in/reader035/viewer/2022071001/5fbe76c55aae5217c34ee8bf/html5/thumbnails/19.jpg)
Breathing
• Listen At Each Lateral Aspect for Breath Sounds
• Interventions– Withdraw ET tube from right mainstem
– Three-sided “occlusive” dressing
– Needle thoracostomy
– Reintubate trachea
– Large bore (38 Fr) tube thoracostomy
– Immediate return of 1500-2000 ml blood is an indication for thoracotomy

Circulation
Apply direct pressure to sites of severe bleeding
Assess blood volume status– Radial pulse ≈ 80 mm Hg
– Femoral pulse ≈ 70 mm Hg
– Carotid pulse ≈ 60 mm Hg
Measure BP including pulse “width”, pulse rate, capillary refill, respiratory rate and rough measure of mental status
![Page 21: ED Management of Trauma - Harvard Universitymycourses.med.harvard.edu/ResUps/ME535M.S/pdfs/HMS_1702.pdf · Hospital trauma designations • Level I – Attending emergency physician](https://reader035.vdocument.in/reader035/viewer/2022071001/5fbe76c55aae5217c34ee8bf/html5/thumbnails/21.jpg)
Circulation
• Seek Beck’s triad – low BP, distended neck veins and muffled heart tones
• Establish 2 large sites of venous access– Peripheral IV’s
– Central venous access
– IO
– Saphenous cut-down

Fundamentals
• Parallel Processing – Team approach allows multiple tasks to be accomplished simultaneously.
• Time is your enemy – Work quickly, quietly and efficiently. A clear and practiced “routine” with well defined roles for team member optimizes outcome.

Fundamentals
• Return to the ABC’s if the patient deteriorates
• Be thorough – Don’t skip steps, avoid distraction.

Fundamentals
• Be skilled – Airway management, team management, vascular access, obtaining history and performing physical exam, procedures!
• Be suspicious – If mechanism or other clues suggest an injury, rule it out.
• Be a team player. Trauma management is a team sport!
