Orthopaedics- Trauma- Management of major trauma Flashcards
What is the basic structure of the Advanced Trauma Life Support guidelines?
Initial primary survey
Secondary survey
What does the initial primary survey consist of?
The ABCDE evaluation: Airway management with cervical spine control Breathing and ventilation Circulation and bleeding control Disability (neurological evaluation) Exposure and environmental control
Name things which could cause airway obstruction in trauma
Foreign bodies
Facial fractures
Swelling from blunt trauma or burns
Reduced conscious level with loss of airway control
List some signs of an obstructed airway
Noisy breathing
Gurgling
Stridor
Agitation from hypoxia and hypercapnia
What can you tell about a patient who is able to speak?
They have a clear airway
What Glasgow Coma Score implies loss of airway control?
What must be done?
8 or less
This requires placement of a definitive airway
What must be done if an airway obstruction cannot be removed expediently?
Emergency cricothyroidotomy
A tube is inserted through the cricothyroid membrane
What should be protected when assessing and managing airway problems?
The C-spine
All major trauma patients should receive high flow oxygen via a tight fitting mask: true or false?
True
How is oxygenation best assessed?
Pulse oximetry
When does tension pneumothorax occur?
When a puncture in the lung results in a one way valve between the lung and pleural cavity resulting in accumulation of air around the lung which can result in collapse and severe respiratory distress.
Name some signs of tension pneumothorax
Trachea may be palpably deviated to the opposite side of the pneumothorax Respiratory distress Tachycardia Hypotension Neck veins will be distended No air entry on the affected side
What is emergency management of a tension pneumothorax?
Needle decompression with a large bore needle in the 2nd intercostal space, midclavicular line before a chest drain is inserted
How is an open pneumothorax treated?
A chest drain is inserted distant from the wound
Describe how adequacy of circulation and perfusion can be assessed?
Pulse rate and volume
Blood pressure
Cardiac monitor- provides continuous information to detect tachycardia, bradycardia and any arrhythmia.
All major trauma patients are given 2L of IV crystalloid initially: true or false?
True
What is essential to gauge fluid balance in a major trauma patient?
Urinary catheterization and urine output monitoring.
What is the minimum accepted urine output?
30ml/hour
What is the first manifestation of hypovolaemic shock?
What is this followed by?
Tachycardia followed by reduction in blood pressure
Confusion and lethargy may also be present
Name signs of cardiac tamponade
How is it confirmed?
Distended neck veins
Muffled heart sounds
Confirmed with echocardiogram
Name signs of severely raised intracranial pressure from intracranial haemorrhage.
Pupils fixed and dilated
How is level of consciousness determined?
Using the Glasgow coma score
Which patients have a higher risk of subdural haematoma, and therefore have a lower threshold for CT scanning?
The elderly
Why must trauma patients be kept warm?
Hypothermia can readily occur in unconscious or immobile patients.
Warmed IV fluids should be administered.
