Study Notes
ABCDE Assessment
- The approach to critically ill patients is consistent
- Use the ABCDE approach for assessment and treatment
- Perform a thorough initial assessment
- Regularly reassess patients
- Prioritize life-threatening issues before moving to other aspects of the assessment
- Evaluate the effectiveness of treatments
Airway
- Airway obstruction is an emergency
- Untreated airway obstruction leads to hypoxia and potential damage to the brain, kidneys, and heart, ultimately risking cardiac arrest and death.
- Obstruction causes paradoxical chest and abdominal movements, and may lead to using accessory respiratory muscles
- Partial obstruction causes reduced air intake and noisy breathing sounds
- Complete obstruction results in a silent chest
Late Sign
- Central cyanosis is a late indicator of a problem
Additional Information
- Obtain expert help if needed
- Simple airway clearance methods may be required (e.g., head tilt, chin lift, jaw thrust)
- More advanced methods (e.g., oropharyngeal or nasopharyngeal airway insertion, laryngeal mask or tracheal intubation) may be necessary
- Provide high-concentration oxygen using a mask with an oxygen reservoir
Breathing
- Assess respiratory rate and chest expansion
- Check for chest deformities (e.g., flail chest)
Palpation
- Feel the chest wall for crepitus or surgical emphysema
- Note any tenderness
Percussion
- Hyperresonance may indicate pneumothorax
- Dullness may indicate pleural effusion
Auscultation
- Listen to the lungs for any abnormal sounds
O2 Saturation
- Track inspired oxygen concentration using pulse oximetry
- Pulse oximetry does not detect hypoxemia
Arterial Blood Gas (ABG)
- Obtain arterial blood gas samples as soon as possible
Circulation
- Assess the color of hands and digits
- Evaluate the state of the veins (collapsed or congested)
- Measure capillary refill time (normally less than 2 seconds)
- Prolonged capillary refill time indicates poor peripheral perfusion
- Assess limb temperature
- Palpate central and peripheral pulses
- Measure blood pressure bilaterally
- Low diastolic blood pressure suggests peripheral vasodilation
- Narrow pulse pressure signifies peripheral vasoconstriction
- Auscultate the heart for any abnormal sounds and murmurs
- Consider inserting two or more wide-bore intravenous cannulae
Blood Tests
- Take blood samples for cross-matching, biochemical analysis, hematological evaluation, and coagulation studies
Fluid Challenge
-
Give a rapid fluid challenge, 500 cc over 5-10 minutes
-
If the patient is hypotensive, give 1000 cc over 5-10 minutes
-
Be cautious with smaller volumes if the patient has heart failure and auscultate the chest for crackles after each fluid bolus
-
Regularly reassess patients
Chest Pain
- If a patient has primary chest pain and suspected acute coronary syndrome, obtain a 12-lead ECG early and treat initially with morphine, oxygen, nitroglycerin, and aspirin.
Disability
- Assess the patient's conscious level using the AVPU method
- Use the Glasgow Coma Scale (GCS) for detailed assessment of level of consciousness, in adults and children
- Look for pupils for size, equality, reaction to light, and other neurological deficits
Secondary Survey
- Gather detailed information about the patient's current complaints, medical history, chronic diseases, previous hospitalizations, medications and allergies, and family medical history.
- Conduct a structured examination of organ systems (respiratory, cardiovascular, abdomen and genitourinary tract, central nervous system, and musculoskeletal).
- Other investigations such as laboratory and radiological examinations may be needed
- Reassess the patient frequently
Exposure
- Fully expose the patient for proper examination but respect patient dignity and minimize heat loss
Additional Considerations
- Always reassess patients
- Consider other causes of decreased level of consciousness (e.g., medications, electrolyte or metabolic disturbances).
- Order blood glucose, electrolytes, renal function, liver function tests, and arterial blood gases.
- Ensure safe transfer to the intensive care unit (ICU) when appropriate
