IVH Score

This score is used for patients with intracerebral hemorrhages with intraventricular extension, and is not appropriate for pure intraventricular hemorrhages.

h

In this score, each lateral ventricle is graded as:

  • 0 = no blood or small amount of layering
  • 1 = up to 1/3 filled with blood
  • 2 = 1/3 to 2/3 filled with blood
  • 3 = mostly or completely filled with blood

3rd and 4th ventricles receive a score of:

  • 0 = for no blood
  • 1 = partially or completely filled with blood

Hydrocephalus was coded as

  • 0 = absent
  • 1 = present

 

The formula for calculating the IVH score is as follows:

e

Or simplified:  3(RV+LV) + III + IV + 3(H)

 

Once the IVH score has been computed, the IVH volume can be calculated using the following formula:

f

 

To make things simpler, here is a table showing the calculated IVH volume based on the IVH score.

Here are two examples of IVH scores calculated for you:

How to use the IVH Score?

With the IVH score, cutoff of 40 mL indicates poor outcome and 60 mL, mortality.

With the ICH score, cutoff is 25 mL and 30 mL respectively.

The total volume of hemorrhage can be calculated by adding the ICH volume (using the ABC/2 formula) and the IVH volume (using the ICH score).   Total volume predicts outcome better than ICH volume alone.

NOTE:  Be wary of using ICH score and IVH score to withdraw care.  Early limitation of care in ICH / IVH is a self-fulfilling prophecy which is, of course, associated with mortality.

    • outpatient work-up within 1-2 days (alternate option: admit for work-up)
    • DIAGNOSTICS:
      • carotid imaging (US, CTA, MRA)
      • Consider TTE; if high suspicion for cardioembolic source / bilateral infarcts, obtain TEE

    • THERAPEUTICS:
      • Start antiplatelet therapy:
        • ASA 81mg/day or
        • Clopidogrel 75mg/day or

        • Atorvastatin 40-80mg/d or
        • Rosuvastatin 20-40mg/day

        • Rosuvastatin 5-10mg/d or
        • Simvastatin 20-40mg/d or
        • Pravastatin 40-80mg/d
      • Consider OAC or LMWH if rhythm shows atrial fibrillation – calculate CHADSVASC and HAS BLED score to guide therapy

    Admit high risk TIAs (ABCD2 scores >3)

    • Admit to hospital
    • Permissive hypertension (up to 220/120mm Hg) and gradually lower over 24-48h

Manual Muscle Testing

Capture

Plus (+) and Minus (-) Grades Use of a plus (+) or minus (-) addition to a manual muscle test grade is discouraged except in three instances: Fair+, Poor+, and Poor-. Scalable gradations in other instances can be described in documentation as improved or deteriorated within a given test grade (such as Grade 4) without resorting to the use of plus or minus labels. The purpose of avoiding the use of plus or minus signs is to restrict the variety of manual muscle test grades to those that are meaningful and defendable.

  • Intubation in ICU (hospitalized in ICU for >24 hours prior to intubation)
  • Tachycardia (HR > 110)
  • Renal dysfunction (BUN > 25)
  • Acidemia (pH < 7.25)
  • Creatinine (>2.0)
  • decreased HCO3(<20)

*Threshold of 4 or more good Sp and Sn in predicting prolonged mechaniascal ventilation

Note: This study excluded neurological patients and therefore cannot be applied in the NSICU setting.

CAVE Score (Seizures after ICH)

The CAVE score is a tool used to quantify the risk of seizure after intracerebral hemorrhage.  Data from Helsinki ICH study and Lille Prognosis of ICH studies were analyzed retrospectively and the authors created the CAVE score to estimate the risk of late seizures after ICH.

1 point is given for each of the following:

  1. cortical involvement
  2. age < 65 years
  3. volume >10ml
  4. early seizures within 7 days  of ICH

 

F2.large.jpg

Risk of seizures based on score:

  • CAVE score 0 = 0.6%
  • CAVE score 1 = 3.6%
  • CAVE score 2 = 9.8%
  • CAVE score 3 = 34.8%
  • CAVE score 4 = 46.2%
