Hypertensive Crises—Emergencies and Urgencies
COR LOE
I B-NR In adults with a hypertensive emergency, admission to an
intensive care unit is recommended for continuous monitoring of
BP and target organ damage and for parenteral administration of
an appropriate agent (Tables 15 and 16).
I C-EO For adults with a compelling condition (i.e., aortic dissection,
severe preeclampsia or eclampsia, or pheochromocytoma crisis),
SBP should be reduced to less than 140 mm Hg during the first
hour and to less than 120 mm Hg in aortic dissection.
I C-EO For adults without a compelling condition, SBP should be
reduced by no more than 25% within the first hour; then, if
stable, to 160/100 mm Hg within the next 2 to 6 hours; and then
cautiously to normal during the following 24 to 48 hours.
