NICE intravenous fluid therapy adults dextrose sodium chloride maintenance fluids guideline

Yes, DNS (dextrose-normal saline) 500 mL can be given after NS 500 mL if it is specifically prescribed and appropriate for the patient.
They serve different purposes:
  • NS 0.9%: usually for volume depletion/resuscitation or sodium replacement.
  • DNS: provides sodium plus glucose, often for maintenance or to help prevent starvation ketosis. It is not usually the first-choice fluid for rapid resuscitation.
Before starting DNS, check the reason for fluids and reassess blood pressure, pulse, urine output, lung signs, blood glucose, sodium, kidney/heart function, and total fluid received. Patients with diabetes, hyperglycemia, heart failure, renal failure, or risk of fluid overload need particular caution.
If the patient has symptomatic hypoglycemia, glucose treatment should be given promptly rather than waiting until the NS finishes.
Do not mix fluids in the same bag or change the sequence/rate without the prescriber’s order. IV fluid therapy should be prescribed according to whether the goal is resuscitation, replacement, or maintenance, with ongoing monitoring, as outlined in NICE IV-fluid guidance.

NICE CG174 intravenous fluid resuscitation 0.9% sodium chloride glucose maintenance

Yes. DNS 500 mL can be given after NS 500 mL, but only if it is ordered for that patient and the reason is appropriate.
  • NS is commonly used first for dehydration or low blood pressure.
  • DNS contains dextrose plus normal saline and may be used afterward for maintenance or when glucose is needed.
Do not give DNS routinely if the patient has:
  • Diabetes or high blood sugar
  • Heart failure, kidney disease, swelling, or breathing difficulty
  • High sodium/chloride levels
  • Fluid restriction
The doctor/nurse should reassess blood pressure, pulse, urine output, blood glucose, and signs of fluid overload before the second 500 mL. Follow the prescribed rate, do not run it rapidly unless specifically ordered.
If this is for a child, elderly patient, pregnant person, or someone with kidney/heart disease, confirm with the treating clinician before starting DNS.
