Triage/initial assessment 1.1 Flashcards
What is included in a minimum database?
PCV
TS
BUN
Blood glucose
What is included in an extended database?
Minimum +
Electrolytes
Blood gases
Lactate
Blood smear
Alongside the emergency database, what other bloods are useful to obtain during the initial exam period?
Biochemistry
Haematology
Coagulation profile
What might snappy pulses indicate?
Anaemia
What does bounding pulses indicate?
Sepsis due to vasodilation
What can a prolonged CRT indicate?
Hypoperfusion/shock
What do pale mucous membranes but normal CRT indicate?
anaemia
What is the definition of tachycardia in dogs?
Above 140bpm. Although it is important to note trends more than individual readings if possible
Name potential causes for tachycardia in dogs
Arrhythmias
CHF
anaemia
stress
pain
excitement
electrolyte abnormalities
intoxications
What is the definition of tachycardia in cats?
Above 180bpm
Name potential causes for tachycardia in cats
Stress
Pain
Anxiety (white coat effect)
Hyperthyroidism
CHF
Electrolyte disturbances
Intoxications
Name potential causes for bradycardia in dogs
Hyperkalaemia
Increased vagal tone
Drugs
Bradyarrhythmias
Raised ICP
Hypothermia
Name potential causes for bradycardia in cats
Shock (later stage)
Sepsis
Hyperkalaemia
AV block
Hypothermia
High vagal tone (uncommon in cats)
What is a special consideration when assessing pulses in cats with aortic thromboembolism?
Compare femoral pulses bilaterally
Also assess forelimbs as ATE can occasionally affects these
What would muffled/absent heart sounds ventrally indicate?
Pleural effusion
What would muffled/absent heart sounds dorsally indicate?
Pneumothorax
When might a gallop rhythm be noted in a cat?
HCM
When might an increase in respiratory effort be seen?
Pleural space disease
Pulmonary parenchymal disease
Upper airway disease/airway obstruction
At what rate is a respiratory rate considered tachypnoea?
Above 50 breaths per minute
Name potential causes for tachypnoea in both cats and dogs
Stress
Pain
Pyrexia/fever
Hyperthermia
Compensation for metabolic acidosis
Describe the changes to a patients breathing pattern that would be noted with increased respiratory effort
Increased chest and abdominal muscle movement
Perceived as laboured breathing
Describe the changes to a patients breathing pattern that would be noted with an upper respiratory tract obstruction
Marked inspiratory effort and paradoxical abdominal movement
Describe the changes to a patients breathing pattern that would be noted with bronchial disease
Marked expiratory - due to air entrapment
What could cause a decreased respiratory effort?
Head/spinal injury
Intoxications (i.e. tetanus)
End stage respiratory fatigue
Describe the changes to a patients breathing pattern if paradoxical respiration was noted
Increased intercostal muscle action
Abdominal muscles appear to move inwards
Why does the abdomen appear to be ‘sucked inwards’ during paradoxical breathing?
The increased intercostal muscle action during inspiration draws the diaphragm cranially
Name potential causes for paradoxical breathing
Upper airway obstruction
diaphragmatic injury (rupture or paralysis secondary to the cervical spinal cord or phrenic nerve injurt)
Severe decrease in pulmonary compliance
Describe the correct method of auscultating the lungs
Each hemi-thorax is divided into dorsal, middle and ventral lung fields
Depending on patient size, this may be split into two or three cranial to caudal zones
Each lung field should be auscultated and compared to the adjacent and contralateral fields
