Insights
Late neurological deterioration (LND) occurs in 28.9% of intracerebral hemorrhage patients, influenced by hematoma volume, intraventricular hemorrhage, and admission glucose levels. LND significantly worsens patient outcomes.
Area of Science:
- Neurology
- Neurosurgery
- Critical Care Medicine
Background:
- Intracerebral hemorrhage (ICH) is a significant cause of cerebrovascular disease.
- Factors contributing to neurological decline beyond 48 hours post-ICH are not well understood.
- Late neurological deterioration (LND) is a critical concern in ICH patient management.
Purpose of the Study:
- To determine the incidence and consequences of LND in spontaneous supratentorial ICH.
- To identify independent predictors associated with LND.
- To explore potential mechanisms underlying LND.
Main Methods:
- Analysis of 149 consecutive patients with spontaneous supratentorial ICH from a neuroscience ICU database (2007-2012).
- LND defined as a ≥2-point decrease in Glasgow Coma Scale or death between 48 hours and 1 week post-ICH.
- Logistic regression used to identify predictors of LND and association with unfavorable outcomes (modified Rankin Scale >2).
Main Results:
- LND developed in 28.9% of patients.
- Independent predictors of LND included hematoma volume, intraventricular hemorrhage, and admission serum glucose.
- LND was independently associated with unfavorable outcomes (OR=4.000, p=0.017).
- Increased midline shift, indicating cerebral edema, was associated with LND (OR=3.822, p=0.028).
Conclusions:
- LND is a common complication following ICH, significantly impacting patient prognosis.
- Hematoma volume, intraventricular hemorrhage, and admission glucose levels are key predictors of LND.
- Progression of perihematomal edema may be a contributing mechanism for LND.
Background:
Although intracerebral hemorrhage (ICH) is a common form of cerebrovascular disease, little is known about factors leading to neurological deterioration occurring beyond 48 h after hematoma formation. The purpose of this study was to characterize the incidence, consequences, and associative factors of late neurological deterioration (LND) in patients with spontaneous ICH.
Methods:
Using the Duke University Hospital Neuroscience Intensive Care Unit database from July 2007 to June 2012, a cohort of 149 consecutive patients with spontaneous supratentorial ICH met criteria for analysis. LND was defined as a decrease of two or more points in Glasgow Coma Scale score or death during the period from 48 h to 1 week after ICH symptom onset. Unfavorable outcome was defined as a modified Rankin Scale score of >2 at discharge.
Results:
Forty-three subjects (28.9 %) developed LND. Logistic regression models revealed hematoma volume (OR = 1.017, 95 % CI 1.003-1.032, p = 0.019), intraventricular hemorrhage (OR = 2.519, 95 % CI 1.142-5.554, p = 0.022) and serum glucose on admission (OR = 2.614, 95 % CI 1.146-5.965, p = 0.022) as independent predictors of LND. After adjusting for ICH score, LND was independently associated with unfavorable outcome (OR = 4.000, 95 % CI 1.280-12.500, p = 0.017). In 65 subjects with follow-up computed tomography images, an increase in midline shift, as a surrogate for cerebral edema, was independently associated with LND (OR = 3.822, 95 % CI 1.157-12.622, p = 0.028).
Conclusions:
LND is a common phenomenon in patients with ICH; further, LND appears to affect outcome. Independent predictors of LND include hematoma volume, intraventricular hemorrhage, and blood glucose on admission. Progression of perihematomal edema may be one mechanism for LND.
