HYPERTENSION
Acute or severe hypertension can be life-threatening as it can cause end organ damage, particularly in the heart, brain, and kidney. The etiology of hypertension in acute kidney injury patients may be due to fluid overload or elevated activity of the renin-angiotensin pathway causing systemic vasoconstriction.

The treatment goal is to reduce severity of hypertension and alleviate signs of end organ dysfunction, not to completely normalize blood pressure. Medications commonly used in the acute care or emergency setting include labetolol, nicardipine, hydralazine, esmolol, or nifedipine.8 ACE inhibitors may exacerbate a pre- renal state so should be used with caution in the emergency setting.”
