RECOGNITION AND ASSESSMENT
Specific conditions
If patient has any of the following conditions, follow appropriate condition-specific guideline
Medical guidelines
- Diabetic ketoacidosis
- Hyperosmolar hyperglycaemic state
- Acute adrenal insufficiency
- Acute upper gastrointestinal haemorrhage
- Hypo/hypernatraemia
- Acute cardiac failure
- Acute liver failure
- Acute kidney injury (acute renal failure)
- Hypercalcaemia
Surgical Guidelines
- Diabetes mellitus and requirement for fluids to cover surgery
- Post-operative haemorrhage
- Recent retention of urine
Initial assessment
History
- Intake/absorption, thirst, abnormal losses, comorbidities
- Check NEWS, fluid balance charts, weight
Examination
- Mental status, skin turgor, are eyes sunken?
- Respiratory rate, pulse, capillary refill, JVP when supine, peripheral or pulmonary oedema, BP (postural hypotension?), urine output
- Assess fluid deficit
Investigations
- FBC, U&E, glucose, ESR
- If blood loss suspected, group and save or crossmatch
- If peripheral perfusion is poor, arterial/venous blood gases or lactate to detect metabolic acidosis, CRP, coagulation studies
MANAGEMENT
- Use ABCDE approach and address cause of any fluid deficit
- Assess volaemic status and venous pressure
Fluid deficit
- Go to Fluid Resuscitation guideline
No fluid deficit
- If the patient is able to ingest and absorb normal fluid load and not nil-by mouth, encourage patient to drink and/or give patient fluids enterally – see Practice and ethics of nutritional support in medical patients guideline especially if any complex fluid or electrolyte problems
- If the patient is unable to ingest and absorb normal fluid load or is nil-by mouth, go to IV MAINTENANCE FLUIDS guideline
