Possible Causes of Transient blood pressure elevation • Drug use (cocaine, meth, tobacco) • Obesity (wrong cuff size) • White coat HTN, anxiety • Pain • Hypertensive Disorders of Pregnancy
Categories of Hypertension During Pregnancy • Preeclampsia-eclampsia • Chronic hypertension • Chronic hypertension with superimposed preeclampsia • Gestational hypertension
Chronic Hypertension • Diagnosis: elevated blood pressure > 140/90 prior to 20 weeks gestation x2 at least 4 hours apart
Gestational Hypertension • Diagnosis: HTN (BP > 140/90) after 20 wks pregnancy without proteinuria or other criteria for preeclampsia
Preeclampsia without severe features • Diagnosis: 1. BP > 140/90 x2 at least 4 hours apart 2. proteinuria: >300 mg on 24 hour urine or P/C ratio fo 0.3 or greater • Urinary protein levels do not correlate with severity
Preeclampsia with severe features • BP > 160/110 at least four hours apart unless meds are started before that time • Thrombocytopenia < 100,000 • LFT’s 2x normal or RUQ/epigastric pain • Renal insufficiency: Cr 1.1 or doubling of baseline • Pulmonary edema • New-onset cerebral/visual disturbances ***ANY ONE OF THE ABOVE CRITERIA in combination with hypertension is sufficient for the diagnosis*** Proteinuria is not necessary if any are present
HELLP Syndrome • AST or ALT > 2x normal • LDH > 600 • Bili > 1.2 mg/dL • Platelets < 100,000 • DIC panel (fibrinogen, PT, PTT) should be ordered if plts <50,000 or signs/sx of bleeding • Atypical HELLP may not meet BP criteria for preeclampsia diagnosis
