Trauma management Flashcards

Q

What are some common interventions performed in pre-hospital emergency setting?

A

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

Q

What are components of ‘A’ (ABCDE) ?

A

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

Q

Do we intubate patients with burns?

A

Patients with burn injuries + evidence of respiratory involvement -> often intubated out of precaution

Q

How to ‘prove’ that there is no C-spine injury?

A
  • no evidence of fracture on cervical x ray
  • no signs of tenderness in an otherwise neurologically normal patient

Q

Components of ‘B’ assessment (ABCDE)

A

Breathing

  • Assess oxygenation status with pulse oximetry
  • Inspect and auscultate chest wall for injuries -> absence of breath sounds, asymmetric or abnormal movement

Q

Inunstable patient, if we suspect tension pneumothorax/ haemothorax; do we treat first or do we perform imaging to confirm?

A

In unstable patients, do not delay treatment of tension pneumothorax or hemothorax in favor of imaging.

Q

Components of ‘C’ (ABCDE)

A

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

Q

What IV lines should be placed in the patient during ‘C’ component? Why?

A

Place two large-bore intravenous lines (at least 16 gauge) for blood typing and crossmatch, and resuscitation (if needed).

Q

What if we do not know the patient’s blood group and there is an ongoing hemorrhage?

A

0 type blood transfusion

17
Q

What to do if there are persistent blood loss and hemodynamic instability?

A

Transfuse: plasma, platelets and RBCs - 1:1:1 ratio

*this also will prevent coagulopathy caused by: trauma and massiv transfusion of blood

18
Q

How much blood is required to be lost in order for the hypovolaemic shock to occur?

A

at least 1.5 L

*but haemorrhage may be both: internal and external

19
Q

What are the components of ‘D’ (ABCDE)?

A

Disability

  • GCS
  • pupil size
  • if a patient is interactive: assess motor and sensory function (neuro)
20
Q

What are ‘E’ components in (ABCDE)?

A

Exposure

  • undress patient completely -> examine patient’s body (including back) for other injuries
  • blanket - if hypothermia
  • palpate for rectal injuries and anal tone (PR)
21
Q

What can be a gross haematuria sign of?

A

bladder, kidney, urethral injury

22
Q

What can be a microscopic haematuria sign of in a setting of trauma?

A

Microscopic haematuria is normal after trauma in adults - but should be investigated in paediatrics

23
Q

When do we perform a secondary survey?

A

After:

  • primary survey (ABCDE) has been completed
  • patient is stable
24
Q

Components of secondary survey

A
  • throughout examination
  • history
25
Q

Free fluid in splenorenal recess

  • what does it look like?
  • what does it indicate?
A

Free fluid in splenorenal recess

It is an anechoic area between left kidney and spleen

It indicates the presence of free abdominal fluid

26
Q

FAST exam in the setting of trauma

  • what is it?
  • what is it used for?
A

FAST = Focused Assessment with Sonography for Trauma

  • rapid, standardized bedside USS of polytrauma
  • it is to screen for the presence of free fluid -> which may mean blood (internal hemorrhage)
27
Q

What areas are examined on FAST (4)?

A

FAST -> looks for free fluid (e.g. blood)

Areas of examination:

  • peri-hepatic space and hepato-renal space
  • peri-splenic and splenorenal space
  • pelvis and suprapubic region
  • pericardium
28
Q

What is the main goal of the secondary survey?

A

To reduce the risk of ‘missed injuries’

29
Q

Tertiary survey

  • when is it performed?
  • what is it aim?
A
  • delayed re-examination of the patient (usually ∼ 24 hours after admission)
  • main goal is to detect changes due to previously undetected injuries
