  • What is the expected outcome of a patient with ICH?


Mission statement

Mission Statement

  • ICH is a cause of significant mortality and morbidity. Despite its established burden, considerably less investigative attention has been devoted to the study of ICH than other forms of stroke. Only a limited number of clinical studies have been performed to examine the surgical and medical managements of patients with ICH. No consistently efficacious strategies have been identified in such investigations. Management of ICH unfortunately remains heterogeneous across institutions, and continues to suffer from the lack of proven medical and surgical effectiveness.

  • THIS IS CHANGING

Ich hemorrhage volume

ICH Hemorrhage Volume

  • Old concept-Hemorrhage static process; bleeding complete in a minutes

  • New concept-Hemorrhage is dynamic; process continues for several hours

Comparison of variables between Baseline and 1 hour CTs


Ich growth study conclusion

ICH Growth Study Conclusion

  • Substantial early hemorrhage growth in patients with with intracerebral hemorrhage is common and is associated with neurological deterioration.

  • Randomized treatment trials are needed to determine whether this ongoing bleeding and frequent neurological deterioration can be improved


Ich hemorrhage growth1

ICH Hemorrhage Growth

  • Hematoma growth occurs in patients with normal coagulation profiles

  • Hematoma enlargement is associated with a worse outcome

  • Hematoma growth occurs within the first few hours (up to 40% in the first 3 hours) and is rare after 24 hours

Secondary effects of ich

Secondary Effects of ICH

  • Hematoma initiates edema

  • Edema is from osmotically active proteins from the clot

  • Vasogenic and cytotoxic edema lead to disruption of blood brain barrier and death to neurons

  • There may be unidentified secondary mediators of both neuronal injury and edema ( nuclear factor kappa-beta)

Altered mental status

Altered Mental Status

  • Early decrease in level of consciousness seen about 50% patients

  • Uncommon finding in patients with ischemic stroke

Broderick: Guidelines for the Management of Spontaneous Intracerebral Hemorrhage ;Stroke 1999;30: 905-915


Headache

Headache

  • Occurs about 40% of patients

  • 17% with ischemic stroke

Vomiting

Vomiting

  • 49% ICH

  • 2% Ischemic stroke

    • Mostly lobar

  • Associated with Neurological worsening

  • Trend toward worse outcome

Priorities for Clinical Research in ICH:NINDS ICH Workshop; Stroke March 2005

Ich diagnosis

ICH Diagnosis

CT scan is the most effective tool in the ED

  • CT scan

CT scan is excellent for imaging blood


Poor outcome risk factors

Poor Outcome Risk Factors

  • Large or increasing volume of hematoma

  • Low GCS on admission

  • Interventricular clot extension and/or hydrocehalus

  • Anticoagulation agents

  • Relative edema

Poor outcomes intraventricular extension hydrocephalus

Poor Outcomes- Intraventricular Extension Hydrocephalus

  • Independent prognostic indicator

  • Important cause of neurological deterioration

  • Location importance?

  • Ventriculostomy-helpful?

Priorities for Clinical Research in ICH:NINDS ICH Workshop; Stroke March 2005


Outcome predictor

Outcome predictor

  • Initial GCS

  • Initial hematoma volume

  • If GCS < 9 and hematoma volume > 60 ml mortality at one month 90%

  • GCS > 9 and hematoma volume < 30 ml mortality > 17%

Hemphill III, Bonovich: The ICH Score;Stroke,April 2001 891-896


Ich score1

ICH Score

  • If score was six or greater all patients died

  • If score was zero all patients lived

Hemphill III, Bonovich: The ICH Score;Stroke,April 2001 891-896


Ed patient management

ED Patient Management

  • Patient intubated in the ED

  • Stared on Nicardapine

  • BP-160/84 P-92 RR-Vented

  • Eyes-Pupils fixed

  • Patient expired within two hours of arrival


Key learning points

Key Learning Points

  • ICH makes up only 10-15% strokes

  • ICH occurs in hypertensives greater then 55 yrs of age

  • ICH presents differently than ischemic stroke

  • ICH volume expands over time-this is a marker for poor outcome

  • One can risk stratify poor outcomes based on simple numbers such as GCS, hemorrhage volume
