Trauma - Exam 2 Flashcards by Johannah Crumpton

What are the components of the primary survey? What are the components of the secondary survey? What should you do if there is any change in pt’s status?

Primary Survey:
Airway
Breathing
Circulation
Disability
Exposure

Secondary Survey:
Head to Toe Physical
History as able (AMPLE)

need to start over again at AIRWAY

What things should you be looking for as you are assessing a pt’s airway? When should you intubate?

Foreign Bodies (Teeth)
Facial, Mandibular, tracheal or laryngeal fractures
Fluids: Blood, Mucus, Water (Suction)

need to remove obstructions while keeping the cervical spine motion restricted-> assume cervical spine injury until it has been ruled out

GCS less than 8 = intubate

What is the definition of a definitive airway? What type of pts get a definitive airway automatically?

a tube placed in the trachea with the cuff inflated below the vocal cords, the tube connected to a form of oxygen-enriched assisted ventilation, and the airway secured in place with an appropriate stabilizing method OR surgical airway is also definitive

significant facial or neck swelling or burns -> because the airway will swell

What is the difference between Oxygenation and ventilation?

Oxygenation - getting oxygen into the blood stream, increases partial pressure of oxygen on ABG -> INHALATION

Ventilation - moving air in and out of the lungs, reduces PCO2 on ABG -> EXHALATION

Flaccidity (Loss of muscle tone) and loss of reflexes that occur below level of injury immediately AFTER Spinal Cord Injury usually due to SWELLING **After a period of time, symptoms resolve.

What are the 4 different types of spinal cord syndromes?

Brown-Sequard Central Anterior Posterior

________ usually caused by penetrating trauma directly into the cord - loss of motor function on same side as injury, but sensation on contralateral side

Brown-Sequard

______ usually occurs with a hyperextension injury in a pt who falls from ground level hitting their face with pre-existing cervical stenosis

central

_______ Causes loss of pain and temperature sensation as well as motor function - usually paraplegia - worst prognosis for recovery - Usually from ischemia
