Fluid therapy Flashcards
Give an example of oxygen carrying capacity fluid replacers
Fresh whole blood
Packed RBCs
Synthetic bovine haemoglobin
Give examples of ECF volume replacers
Hartmann’s (isotonic)
Lactated ringers
Isotonic 0.9% saline
Give examples of protein rich ECF volume or colloid osmotic pressure replacers
Synthetic colloids
Fresh plasma
How do synthetic colloids and fresh plasma differ in terms of properties?
Synthetic colloids and plasma both increase oncotic pressure
But only plasma provides protein
Give an example of a cause of whole blood loss
Haemorrhage
Give an example of ECF loss
Diarrhoea, vomiting
Give an example of protein rich ECF loss
Exudative wounds
PLE/PLN
Give an example of pure water loss
Heatstroke
Give an example of abnormal fluid intake
Adipsia
Give an example of abnormal fluid loss
V+
D+
Haemorrhage
Heat stroke
An animal presents with normal demeanour, normal skin elasticity and sticky to dry mucus membranes. Estimate the dehydration
5%
An animal presents with a mildly depressed demeanour, mildly decreased skin elasticity and dry mucus membranes. Eyes are normal. Estimate the dehydration
7%
An animal presents depressed, with a moderately decreased skin elasticity and slightly sunken eyes. Estimate the dehydration
10%
An animal presents moribund with a skin tent, dry mucus membranes and a deeply sunken globe. Estimate the dehydration
12%
What is fluid maintenance rate for small animals?
2ml/kg/hr
What is the estimated fluid loss for each episode of diarrhoea/vomiting?
4ml/kg per episode
What is the bolus fluid rate for an animal in shock?
10-20ml/kg
Over 15-30 mins
Re-evaluate then may need to readminister
What can happen if you over-hydrate an animal when giving a fluid bolus?
Pulmonary oedema
Give examples of a surgical rate for intra-operative fluids
5-10ml/kg/hr
