Hypertensive crisis occurs when a person’s blood pressure surges to an unusually high level. This condition can cause damage to blood vessels and major organs. This article looks at some causes of hypertensive crisis and some treatment options available.
Although no single ideal agent exists, a growing number of drugs are available for the management of hypertensive crises. The agent of choice in any particular situation will depend upon the patient's clinical presentation. The preferred agents include esmolol, labetalol, fenoldopam, and nicardipine.
Clinical manifestations of hypertensive crises. Headache, altered level of consciousness, and/or focal neurologic signs are seen in patients with hypertensive encephalopathy [ 6, 7 ]. On physical examination, these patients may have retinopathy with arteriolar changes, hemorrhages and exudates, as well as papilledema.
Initial therapeutic approach. The majority of patients with severe hypertension (diastolic pressure > 109 mmHg) will have no acute end-organ damage (hypertensive urgencies). In these patients the blood pressure should be lowered gradually over a period of 24–48 hours, usually with oral medication.
The drugs of choice in treating patients with a hypertensive crisis and eclampsia or pre-eclampsia are hydralazine, labetalol, and nicardipine (5,6).
The first-line treatment for hypertensive crisis will typically be intravenous antihypertensive medications to lower the person's blood pressure. Healthcare providers usually aim to reduce blood pressure by no more than 25% in the first hour, as rapid decreases in blood pressure can cause other problems.
Provide oxygen at 2 to 4 liters/min to maintain or improve oxygenation. Minimize oxygen demand by maintaining the patient at bed rest. Help the patient decrease anxiety, and keep the patient NPO or provide a liquid diet in the acute phase. Administer nitrates as ordered to reduce preload and afterload.
Hypertensive crisis occurs when your blood pressure becomes dangerously high (180/120 mm Hg), to a level that can damage your organs.
What are the causes of hypertensive crisis? The most common cause of hypertensive emergency is an abrupt increase in blood pressure in patients with chronic hypertension. Medication noncompliance is a frequent cause of such changes.
Especially severe cases of hypertension, or hypertensive crises, are defined as a BP of more than 180/120 mm Hg and may be further categorized as hypertensive emergencies or urgencies.
The term hypertensive emergency is primarily used as a specific term for a hypertensive crisis with a diastolic blood pressure greater than or equal to 120 mmHg or systolic blood pressure greater than or equal to 180 mmHg.
“The American Heart Association states that a reading of 180/110 or greater requires immediate medical attention. If you take this reading two times in a row, five minutes apart, then you must head to the nearest ER,” says Dr. Meier.
If your blood pressure is 180/120 or higher AND you are experiencing symptoms that could be related to your high blood pressure you should go to the Emergency Room immediately.
Normal pressure is 120/80 or lower. Your blood pressure is considered high (stage 1) if it reads 130/80. Stage 2 high blood pressure is 140/90 or higher. If you get a blood pressure reading of 180/110 or higher more than once, seek medical treatment right away.
Of the 670 patients, 57.5% had hypertensive emergencies; 98% of those with hypertensive emergencies and 23.2% of those with hypertensive urgencies were hospitalized. Median survival was 14 days for those with neurovascular emergencies and 50 days for those with cardiovascular emergencies.
