Background

  • 1% of patients with DKA[1]
  • Cerebral edema
  • Almost all affected pts are <20yr [2]
  • Associated with initial bicarb level; not rate of glucose drop

Risk Factors

  1. Age <5yo
  2. Severe hyperosmolality
  3. Failure of Na to rise w/ therapy
  4. Severe acidosis
  5. Overaggressive fluid resuscitation is NOT a risk factor

Clinical Features

  • Begins 6-12hr after onset of therapy or may begin before initiation of treatment or up to 48h afterward
    • Many appear to be improving from their DKA before deteriorating from cerebral edema
  • Premonitory symptoms:

Differential Diagnosis

Workup

Management[3]

  • Head of bed at 30 degrees
  • Stat head CT (non-contrast)
  • Mannitol 0.5-1gm/kg IV bolus over 20 minutes
    • Give a repeat does if there is an inadequate response
    • If 2 doses of mannitol are ineffective, consider 3% saline 10mL/kg over 30min
  • Fluid restriction - decrease the IVF infusion rate by 30%
  • Consult PICU and neurosurgery

Admit ICU
