Addressing hypertensive emergencies Flashcards
When considering the risks of malignant hypertension, the big question is?
Do we see signs or symptoms of end-organ dysfunction?
3 signs and symptoms to watch for:
- Chest pain - ischemia or aortic dissection
- SOB - pulmonary edema
- Neurologic deficits - stroke or encephalopathy
How to break down HPT emergencies:
- Non-stroke HPT emergencies - Aortic Dissection vs Pheochromocytoma vs Other Cardio HPT Emergencies
- Stroke HPT emergencies - haemorrhagic vs ischaemic
Mx of Aortic Dissection:
First hour: reduce the SBP to < 120
Mx of Pheochromocytoma:
First hour: reduce the SBP to < 140
Mx of Other cardiology-related hypertensive emergencies:
- First hour: reduce BP by 25%
- Next 2–6 hours: try to keep it in the 160/110 range
- Next 24–48 hours: slowly bring it down to the normal range - 120/80
Hemorrhagic stroke - w/in 6 hours of the onset of symptoms - Systolic BP is 150–220 mmHg:
**Do nothing **
Hemorrhagic stroke - w/in 6 hours of the onset of symptoms - Systolic BP is > 220 mmHg::
- IV antihypertensives
- Lower SBP to 150–220
Ischemic stroke - If you’re seeing a patient within 72 hours of the onset of symptoms, the first thing you want to do is?
Check whether they qualify for IV thrombolytics
Mx - Ischemic stroke w/in 72 hours of Sx onset - Qualifies for thrombolytcis - Yes:
- IV antihypertensives
- Reduce BP to < 185/110
- Give Thrombolytics
- Maintain BP at < 185/110
Mx - Ischemic stroke w/in 72 hours of Sx onset - Qualifies for thrombolytcis - NO - BP < 220/110:
- Do nothing
- Monitor BP for first ** 48–72 hours**
Mx - Ischemic stroke w/in 72 hours of Sx onset - Qualifies for thrombolytcis - NO - BP < 220/110:
Do nothing (monitor BP) for first ** 48–72 hours**
Mx - Ischemic stroke w/in 72 hours of Sx onset - Qualifies for thrombolytcis - NO - BP > 220/110:
- IV antihypertensives
- Lower BP by 15% in first 24 hours
