Q

what are the 4 types of circulatory shock?

A

hypovolaemic
maldistributive
cardiogenic
obstructive

160
Q

what is shock?

A

significant compromise in oxygen delivery to tissues

161
Q

what are the 3 ways to get shock?

A
  • failure of circulatory system (circulatory shock)
  • failure of blood to carry enough oxygen (V/Q mismatch)
  • failure of tissues to utilise oxygen effectively (cyanide toxicity)
162
Q

what are hyperdynamic pulses?

A

taller as greater difference between diastolic and systolic pressure

163
Q

what is different about cats in shock?

A

can get bradycardia as their HR is closely regulated to core temp so if get cold then HR slows down

164
Q

What is hypovolaemic shock?

A

tissue hypoperfusion secondary to a lack of circulating blood volume
-fluid lost from intravascular volume

165
Q

what is the difference between dehydration and hypovolaemia?

A

-dehydration is fluid loss from all 3 compartments - intracascular, interstitial and intracellular whereas hypovolaemia is reduced intravascular volume

166
Q

what can cause hypovolaemia?

A

haemorrhage
fluid loss into GIT
fluid loss into third space

167
Q

what are some consequences of hypovolaemia?

A

reduced venous return, mismatch in o2 supply/demand, anaerobic metabolism and lactate build up

168
Q

what are signs seen in early compensatory hypovolaemic shock?

A
HR 130-150
MM normal or even pinker - rapid CRT
bounding hyperdynamic pulses
easily palpable metatarsal pulse
lactate 3-5 mmol/L
169
Q

what are signs seen in late decompensated hypovolaemic shock?

A
HR 170-220
white / grey MM
long or absent CRT
weak / thready pulses
absent metatarsal pulses
lactate over 8 mmol/L
maybe low bp
170
Q

what is the treatment for hypovolaemic shock?

A
  • IV fluid bolus (isotonic crystalloids) 10-40ml/kg in 20 mins then reases
  • monitor for dyspnoea
171
Q

A

60-90 ml/kg

172
Q

what is cat blood volume?

A

40-60 ml/kg

173
Q

what is a consideration in fluid therapy in large dogs?

A

the volume needed isnt possible in short amount of time so could give hypertonic crystalloids

174
Q

what may colloids be used in hypovolaemia?

A

they stay in intravascular volume for longer than crystalloids which equally diffuse across all compartments
