Preeclampsia with severe features is defined as the presence of one of the following symptoms or signs in the presence of preeclampsia [1] :

  • SBP of 160 mm Hg or higher or DBP of 110 mm Hg or higher, on two occasions at least 4 hours apart while the patient is on bed rest (unless antihypertensive therapy has previously been initiated)

  • Impaired hepatic function as indicated by abnormally elevated blood concentrations of liver enzymes (to double the normal concentration), severe persistent upper quadrant or epigastric pain that does not respond to pharmacotherapy and is not accounted for by alternative diagnoses, or both.

  • Progressive renal insufficiency (serum creatinine concentration >1.1 mg/dL or a doubling of the serum creatinine concentration in the absence of other renal disease)

  • New onset cerebral or visual disturbances

  • Pulmonary edema

  • Thrombocytopenia (platelet count < 100,000/μL)
