Estado Hiperosmolar Hiperglucémico (EHH)
“ Hiperglucemia (glucosa sérica >600mg/dl) e hiperosmolaridad (>320mOsm/L) en
ausencia de cetonemia significativa y acidosis ”
Estado Hiperosmolar no cetósico
Coma Hiperosmolar
Estado Hiperosmolar Hiperglucémico (EHH)
Frecuencia DM2 > DM1. Edad media 65 años Debutan con EHH 30-40%. < 1% de admisiones por DM. Mortalidad de al menos 10%. Cetosis moderada es comun Coma <30%.
Estado Hiperosmolar Hiperglucémico (EHH)
Fisiopatología de EHH
Deficiencia de insulina y aumento de hormonas contrarreguladoras.
Diagnóstico EHH
Criterios diagnósticos EHH : a. Glucosa sérica >600 mg/dl
b. pH arterial >7.3
c. bicarbonato sérico >15 mEq/l
d. and mínima cetonuria and cetonemia.
