Q

How do you assess the airway?

A
  1. LOOK
    - Inspect for any foreign bodies
  2. LISTEN
    - Is the patient able to communicate verbally?
    - stridor : high pitched whistling sound heard while taking in a breath
    - hoarseness : changes in pitch or quality of voice which may sound weak, husky or scratchy
    - gurgling : hollow bubbling sound
    - pooled secretions or blood
  3. FEEL
    - Inspect for any foreign bodies

Q

Describe an oral airway intervention?

A

oropharyngeal airway
- a rigid curved device placed in the mouth to prevent the tongue from occluding the airway
Note: to be used on unconscious patients with airway obstruction - no gag reflex

Q

Describe a nasal airway intervention?

A

nasopharyngeal airway
- a soft flexible tube inserted through the nares into the nasopharynx to prevent the tongue from occluding the airway
Note: used in patients with current or potential oropharyngeal obstruction and contraindicated in facial fractured, basilar fractures and coagulopathy (nosebleed)

Q

Types of definitive airway?

A
  1. orotracheal
  2. nasotracheal
    e.g. endotracheal intubation
  3. surgical airways
    e.g. cricothyroidotomy/tracheostomy
    Note: cricothyroidotomy does not need sedation
  4. rapid sequence intubation/induction

Q

What is rapid sequence induction?

A

rapid induction of anaesthesia and paralysis followed by immediate intubation without intervening attempts at ventilation
- used when patient is at risk of aspiration
e.g. nonfasting state, GI bleed, bowel obstruction, pregnancy

Q

How do you assess breathing?

A
  1. Inspect, palpate, and auscultate
    - Respiratory distress – RR, work of breathing
    - Deviated trachea, crepitus, flail chest, sucking chest wound, absence of breath sounds
    - Saturations, mental status
  2. CXR to evaluate lung fields

Q

Breathing interventions?

A
  1. Ventilate with 100% oxygen
  2. Needle decompression if tension pneumothorax suspected
  3. Chest tubes for pneumothorax / hemothorax
  4. Occlusive dressing to sucking chest wound
  5. Analgesia for flail chest
17
Q

How do you assess circulation?

A

Rapid assessment of hemodynamic status
1. Level of consciousness
2. Skin color and temperature
3. Pulses rate
4. Blood pressure and pulse pressure
5. Cool peripheries
Note: Hemorrhagic shock should be assumed in any hypotensive trauma patient

18
Q

Circulation interventions?

A
  1. CPR
  2. Control hemorrhage
    - Pressure
    - Splint
    - Explore and clip
    - Surgery
  3. Establish IV access
    - 2 large bore IVs
    - Central lines if indicated
  4. Cardiac tamponade decompression if indicated
  5. Volume resuscitation
19
Q

Contraindications of foley catheter?

A

signs of possible urethral injury
1. Blood at urethral meatus
2. Perineal eccymosis
3. Blood in the scrotum
4. High riding prostate
5. Pelvic Fractures
Note: If suspicious of urethral injury -retrograde urethrogram prior to insertion

20
Q

Describe fluid resuscitation?

A

1-2 LITRES IN ADULT
20ML/KG IN CHILDREN

21
Q

Assessment of disability?

A

baseline neurologic evaluation
1. GCS scoring
2. pupillary response
- observe for neurologic deterioration

22
Q

What is AVPU?

A

criteria for neurologic evaluation
1. Alert
2. Verbal
3. Pain
4. Unresponsive

23
Q

Describe the AVPU score?

A

system by which a health care professional can measure and record a patients level of consciousness
Alert = GCS 15
Voice = GCS 13
Pain = GCS 8
Unconscious = GCS 6

24

25
Assessment of exposure?
1. Complete disrobing of patient 2. Logroll to inspect back 3. Rectal examination 4. Warm blankets/external warming device to prevent hypothermia which leads to coagulopathy.
