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
- Age <5yo
- Severe hyperosmolality
- Failure of Na to rise w/ therapy
- Severe acidosis
- 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:
- Headache
- Incontinence
- Acute Mental Status Change / Seizure
- Signs of herniation
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%
- Treat noncardiogenic pulmonary edema, if present
- Consult PICU and neurosurgery
Disposition
Admit ICU
