An immediate, significant increase in blood pressure accompanied by symptoms of target organ damage is referred to as a hypertensive emergency.
These include myocardial ischemia, eclampsia, pulmonary hypertension, cognitive impairments, aortic dissection, and severe renal failure.
Blood pressure is aggressively lowered if a patient’s organ function suddenly deteriorates. In all other circumstances, blood pressure should be gradually decreased to prevent neurological impairment caused by low perfusion.
Epidemiology
About 30% of adult Americans are estimated to have hypertension. A hypertensive crisis, which includes hypertension urgency and emergency, affects 1% to 2% of these people.
The most typical causes of acute target organ dysfunction include cardiac ischemia, acute pulmonary edema, and cognitive emergencies.
The easy accessibility of antihypertensives in North America has reduced hypertension events and enhanced survival. However, a neglected hypertensive emergency might be fatal.
Anatomy
Pathophysiology
End-organ impairment in hypertensive emergencies is a poorly understood pathogenesis. Mechanical stress on vascular walls will likely cause endothelial damage and a pro-inflammatory response.
This causes enhanced vascular permeability, platelet and coagulation cascade activation, and fibrin clot deposition, which causes hypoperfusion at the target organ tissue level.
Etiology
Multiple triggering circumstances result in hypertensive crises; patients with chronic hypertension experience more hypertensive emergencies. The two most frequent causes are using sympathomimetics and not following antihypertensive drugs as prescribed.
These cause a rapid increase in blood pressure that exceeds the body’s natural ability to regulate it. Patients with chronic hypertension might exhibit hypertensive emergency symptoms at low blood pressure levels.
In contrast, chronic hypertension patients may tolerate high blood pressure without acute organ impairment. The rate of rising above baseline is likely a more significant contributor.
Genetics
Prognostic Factors
Hypertensive crises in the past were frequently accompanied by myocardial infarction, stroke, kidney damage, or death. Over the past three decades, mortality has drastically dropped due to increased knowledge and better blood pressure management.
However, improving blood pressure control is essential to reduce mortality and morbidity following the initial treatment. Unfortunately, there is uncertainty around the long-term prognosis of patients with hypertensive crises.
A significant percentage of individuals could experience unfavorable cardiac events or a stroke within a year.
Administer a dose of 10 to 40 mg intramuscularly or intravenously and dose should not be more than 20 mg
Repeat as required
Associated with Pregnancy
Administer dose of 0.5 to 10 mg/hr as intravenous infusion
For Infants or older:
Administer dose of 0.1 to 0.2 mg/kg intravenously or intramuscularly every 4 to 6 hours initially ass needed; it may raise to usual dose of 1.7 to 3.5 mg/kg daily divided every 4 to 6 hours
Dose should not be more than 20 mg intramuscularly
