An 85 year old man receives IV fluids for 3 days following a stroke; he is not allowed to eat. He has ankle oedema and a JVP of +5 cms; his charts reveal a total input of 9 litres and a urine output of 6 litres over these 3 days. Questions:
1. How much fluid has he accumulated during the last 3 days?
2. What would you do with his IV fluids?
3. Do you have any comments about the probable state of his fluid balance 3 days ago?
