Trauma management Flashcards
What are some common interventions performed in pre-hospital emergency setting?
Low-threshold interventions that may be performed by emergency personnel prior to transport to a hospital include, but are not limited to:
- Placement of a cervical collar (if cervical spine trauma is suspected)
- Intubation or oxygen delivery via nasal cannula (if respiratory distress or altered mental status is suspected)
- Administration of intravenous fluid (if hemorrhage or hypotension is suspected)
- Administration of analgesia
- Placement of tourniquets or pressure bandages for control of bleeding
What technique/protocol do we use in primary survey?
Advanced Trauma Life Support (ATLS) -> ABCDE steps performed in order
What are components of ‘A’ (ABCDE) ?
Airway assessment
(and cervical spine stabilization)
- If appropriately answering questions ->patient has a patent airway (at least for the moment)
- Observe patient for signs of respiratory distress
- Inspect mouth and larynx for injury or obstruction
- Assume cervical spine injury in blunt trauma patients until proven otherwise
- If patient is unconscious (and therefore unable to protect their airway) or in respiratory distress, the threshold for intubation is very low
Do we intubate patients with burns?
Patients with burn injuries + evidence of respiratory involvement -> often intubated out of precaution
What to do if orotracheal intubation fail?
Perform cricothyrotomy
How to ‘prove’ that there is no C-spine injury?
- no evidence of fracture on cervical x ray
- no signs of tenderness in an otherwise neurologically normal patient
Possible signs of respiratory distress (3)
- tachypnoea
- use of accessory muscles
- stridor
Components of ‘B’ assessment (ABCDE)
Breathing
- Assess oxygenation status with pulse oximetry
- Inspect and auscultate chest wall for injuries -> absence of breath sounds, asymmetric or abnormal movement
Inunstable patient, if we suspect tension pneumothorax/ haemothorax; do we treat first or do we perform imaging to confirm?
In unstable patients, do not delay treatment of tension pneumothorax or hemothorax in favor of imaging.
What central pulses do we palpate?
Central pulses
- carotid
- femoral
What peripheral pulses do we palpate?
radial, popliteal, posterior tibial, dorsalis pedis
Components of ‘C’ (ABCDE)
Circulation
- palpate pulses: central and peripheral
- BP (if possible, but if it cannot be done then just move to the other steps of assessment)
- place IV lines -> intraosseous line if IV placement impossible
- control of haemorrhage -> ongoing pressure or tourniquet placement
- look for signs of hypovolaemic shock
What IV lines should be placed in the patient during ‘C’ component? Why?
Place two large-bore intravenous lines (at least 16 gauge) for blood typing and crossmatch, and resuscitation (if needed).
How do we control ongoing hemorrhage in prehospital setting?
Manual pressure or tourniquet
What do we do if the patient is hypotensive?
Bolous IV saline fluid administration
