2. • DKA & HHS associated with high mortality rates if left not treated.
• significant likelihood of morbidity & mortality, including cerebral edema,
permanent neurological injury & death.
• mortality rate for DKA is < 1% & ~ 15% for HHS.
• DKA & HHS have similar pathophysiology with some few differences.
• occur because of lack of insulin effect
• Typically, pts with T1DM more likely to exhibit DKA because of absolute
insulin deficiency, & T2DM more likely to experience HHS
5. Diagnosis – History & Physical exam
DKA
• develops rapidly, over a
time span of <24 h
• nausea & vomiting:
common symptom
• Abdominal pain,
sometimes mimicking an
acute abdomen
• full alertness to profound
lethargy
• fruity breath odor,
• Kussmaul
HHS
• several days before
admission
• polyuria, polydipsia &
weight loss
• mental obtundatioh & coma
more frequent
6. Laboratory
• Immediate: BG, ABG, & Ureum/BUN
• serum electrolytes,osmolality, creatinine & ketones
• urinalysis; ketonuria
• CBC with differential.
• Bacterial cultures of urine, blood, & other tissues
appropriate antibiotics should be administered if
infection is suspected.
18. Monitoring
• serum glucose: every 1-2 h during treatment
• Serum electrolytes: every 2-6 h, depending on the clinical
response of the patient
• the precipitating factor must be identified & treated.
