Abstract
Acute hypertension managed with intravenous antihypertensives has an all-cause in-hospital mortality rate of nearly 7%; with 59% of patients developing worsening organ dysfunction.1 The cost of hypertension associated with a secondary diagnosis in hospitalized patients is $2,734.2 Currently, national treatment guidelines for acute hypertension are not available for adult intensive care unit (ICU) patients. Recently, a survey was conducted to evaluate the management of acute hypertension.3 This survey discovered that only 8.2% of responders had a guideline in place to treat acute hypertension in non-stroke patients. There is also substantial variability in the intravenous agents selected to treat acute hypertension.1,3 In regards to the number of patients admitted to the ICU with acute hypertension, physicians surveyed reported that approximately five patients are admitted with a hypertensive emergency to their ICU each month and approximately the same number develop a hypertensive emergency during their ICU stay.3 With the frequency of acute hypertension and the safety concerns associated with intravenous antihypertensive agents, a review of the medications commonly used in the ICU to treat acute hypertension in special populations was conducted.
