ABCDE Assessment

Question 1

THE ‘DR ABCDE’ ASSESSMENT

Answer 1

• The ‘DR ABCDE’ approach to assessing an acutely unwell patient should be at the front of
  every junior doctor’s mind whenever they get bleeped or asked to see a patient.
• Is this patient becoming unwell rapidly? What can I do about it? The first response should be
  to carry out an A - E assessment and deal with each issue as it is discovered.
• Airway, breathing and circulation should all be assessed using the ‘look, feel, listen, measure, treat’ algorithm. ‘Measure’ usually involves taking vital observations, as well asbedside investigations and basic imaging. ‘Treat’ involves administering any urgent treatment to counteract each abnormal finding
• Treat and reassess at each stage of ABCDE - do not move on to the next stage unless you are satisfied you have optimised any abnormalities your have found. For example, don’t assess breathing and circulation if you have found an airway obstruction that hasn’t been dealt with! Vitally, consider calling for help at EVERY STAGE of this process

Question 2

The first thing!

Answer 2

Wash hands and put on gloves

Shout for help

Approach with care

D: Assess for danger

R: Evaluate patient response

Question 3

1. A. Airway

Answer 3

If the patient is talking then the airway is patent
If not - put your face sideways by the patient:
Look for:

• Obstructions in the airway
• Chest movements
• Cyanosis

Feel for:

• Breath on your cheek
• Listen for:
• For breath sounds
• Stridor (inspiratory)
• Wheeze (expiratory)
• Gargling

Question 4

2. A. Airway

Answer 4

If there is no patent airway - call for help! Give your name, location
and the event.

Treat:

• Remove any solid obstructions with Magill forceps
• Remove liquid obstructions with a Yankauer sucker
• Consider airway manuveres such as a head-tilt/chin-lift or
• If required insert an airway adjunct such as a
  nasopharyngeal tube or if GCS<8 use a Guedel
  (orophayngeal) airway (you should have called for expert
  by this stage)

​Reassess!

Question 5

1. B: Breathing

Answer 5

Look for:

• Respiratory distress
• Use of accessory muscles
• Cyanosis
• Gasping, pursed lips, nasal flaring
• Tracheal tug (more common in children)
• Sweating
• Thoracic wounds/scars

Feel for:

• Tracheal deviation
• Asymmetry in chest expansion
• Change in percussion note (?effusion)

Listen for:

• Asymmetry of breath sounds
• Added sounds
• Crepitations in lung bases
• Wheeze

Question 6

2. B. Breathing

Answer 6

Measure:

• Pulse oximetry
• Respiratory rate
• Consider an ABG
• Consider a chest radiograph
• Consider a peak flow if asthma related distress

Treat:

• Give 85% oxygen >10 l/min via an oxygen mask and
• reservoir bag
• If the patient has COPD, give 35% oxygen via a Venturi
• variable valve mask and reservoir bag until you have an
• ABG (reassess)
• Aim to keep sats >94% unless known CO2 retainer
• Monitor effectiveness with ABGs
• If anaphylaxis with bronchospasm - consider
• adrenaline/steroids
• If infection - consider antibiotics
• If wheeze - consider salbutamol
• Consider asking for further help, e.g.: do you need to
• consider non-invasive ventilation/intubation

Reassess!

Question 7

1. C. Circulation

Answer 7

Look for:

• Pallor (anaemia?)
• Visible blood loss
• Cyanosis
• Sweating
• Jugular venous pressure

Feel for:

• Peripheral perfusion (is the hand cold?)
• Peripheral capillary refill
• Pulse rate and character
• Peripheral oedema

Listen for:

• Heart sounds (gallop/third heart sound of failure/significant murmur)

Question 8

2. C. Circulation

Answer 8

Measure:

• Temperature
• Heart rate
• Blood pressure
• Urine output
• Central capillary refill time

Treat:

• 2 wide bore IV cannulae in the ante-cubital fossae
• Take bloods as necessary (eg FBC, U&Es, LFTs, Crossmatch,
• Clotting, Cultures, Toxicology screen, Calcium, Magnesium)
• IV fluids: fast if signs of shock (250mls stat fluid challenge)
• Blood if active blood loss (if urgent, O -ve until crossmatched blood arrives)
• Antipyrexial medication (paracetamol) if appropriate
• Consider catheterisation, and strict fluid input/output chart

Reassess!

• Take care with fluids in: cardiogenic shock (raised JVP,
  crackles, swollen ankles, sacral oedema), renal failure (check U&Es and refer to renal team), post renal failure

Question 9

D. Disability

Answer 9

Consciousness:

• AVPU: alert/responds to voice/responds to pain/unresponsive
• Formal GCS if response impaired
• Blood glucose level (Don’t Ever Forget Glucose!) - if low give PO/IV glucose, if high consider sliding scale

Question 10

E. Exposure

Answer 10

• Top to toe examination
• Look for any signs of haemorrhage, bruising, infection, injury, etc.
• Examine for gross neurological deficit
• Check for pupillary response and papilloedema

PEARL: Pupils Equal And Reactive to Light.

Question 11

Next step:

Answer 11

• Continuous reassessment
• Discuss with seniors and ITU (if not already involved)
• Look at patient’s notes and charts
• Gather collateral history - ‘AMPLE’

Allergies
Medications
Past medical history
Last oral intake
Events leading up to deterioration

• Review results of routine investigations (including biochemistry, microbiology,
  haematology, radiology, ECG, ABG)
