Severe hyperglycaemia (diabetic ketoacidosis (DKA) and hyperosmolar hyperglycaemic state (HHS))

E10.0-1/E11.0-1/E12.0-1/E13.0-1/E14.0-1

DESCRIPTION

Clinical features of severe hyperglycaemia include:

  • dehydration
  • drowsiness, confusion, coma
  • abdominal pain
  • acetone/fruity smelling breath
  • vomiting
  • elevated blood glucose
  • deep sighing respiration

MEDICINE TREATMENT

Adults

Average fluid deficit 6 L, and may be as much as 12 L.
Be cautious in renal and cardiac disease.
In the absence of renal or cardiac compromise:

  • Sodium chloride 0.9%, IV, 15–20mL/kg in the first hour
    • Subsequent infusion rate: 10mL/kg/hour with 20mL/kg boluses if shocked.
    • Do not exceed 50mL/kg in the first 4 hours.
    • Correct estimated deficits over 24 hours.

Refer urgently with drip in place and running at planned rate.

When referral will take more than 2 hours and a diagnosis of diabetes with hyperglycaemia is confirmed:

  • Insulin, short acting, IM, 0.1unit/kg.
    • When giving insulin IM, do not use insulin needle.

CAUTION

Do not administer short acting insulin if the serum electrolyte status, especially potassium is not known.
Continue with fluids but delay giving insulin in these cases in consultation with referral facility as this delay should not negatively affect the patient, but hypokalaemia with resultant cardiac dysrhythmias definitely will.

Children

If in shock:

  • Sodium chloride 0.9%, IV, 20 mL/kg as a bolus.
    • If shock not corrected, repeat the bolus.
    • If a 3rd bolus is required, consult with a paediatrician.

If no shock or aftershock is corrected:

  • Sodium chloride 0.9%, IV.

Refer urgently with drip in place and running at planned rate.

When referral will take > 2 hours and a diagnosis of diabetes with hyperglycaemia is confirmed and provided glucose is monitored hourly:

  • Insulin, short acting, IM, 0.1 units/kg after 1st hour of infusion of saline
    • When giving insulin IM, do not use insulin needle.
