Must know Target BP values in neuro-emergencies
This is a must know topic that is asked in UPSC CMS, NEET PG and INICET examinations. Go through this mini blog with approximate read time of 3 minutes and remember each line.
|
Condition |
Target |
Remarks |
|
SAH |
SBP < 140-160 For raised ICP: Keep CPP > 60 |
Prevent re-bleeding while maintaining cerebral perfusion. |
|
Spontaneous ICH |
SBP -140/90 |
Reduces hematoma expansion |
|
Acute Ischemic Stroke (Thrombolysis Candidate) |
Pre-lysis: SBP < 185, DBP < 110 Post-lysis (24h): SBP < 180, DBP < 105 |
Reduces risk of ICH due to Thrombolytics |
|
Acute ischemic Stroke (No Thrombolysis) |
If SBP > 220 or DBP > 120 ↓BP by -15% in 24h |
Permissive HTN supports penumbra perfusion. Avoid rapid/larger drops.
|
|
Hypertensive Encephalopathy |
↓ MAP by 20-25% in 1st hour, then gradual |
Symptoms improve with controlled reduction. |
|
Traumatic Brain Injury |
SBP 100 CPP 60-70 |
Keep CPP > 60 mmm Hg if ICP monitor available |
|
Aortic Dissection |
HR < 60 bpm SBP 100-120 |
Reduce shear stress. Treat pain/anxiety first. First-line: β-blockers (Labetalol, Esmolol), |
First-line agents (neuro HTN): Nicardipine and Labetalol
Avoid: Nitroprusside, Nitroglycerin
NTG may be required if pulmonary edema present due to cardiac comorbidity and needs individual
