[Outcome evaluation in putaminal hemorrhage by multiple regression analysis]

The aim of this study was to determine the factors that influence the prognosis of hypertensive putaminal hemorrhage. We investigated the outcome of the activity of daily living (ADL 1: full recovery at social life, 2: self cared, 3: required partial care at home, 4: remained bedridden, 5: vegetative state, 6: dead) one year after the onset of putaminal hemorrhage in comparison with initial data obtained on the day when it occurred. The following parameters were assessed: sex, age, side of hematoma, classification of computed tomography (CT) findings, neurological grade, degree of muscle power, hematoma volume, treatment, past history of cerebrovascular disease, and laboratory data. In 67 patients with putaminal hemorrhage, the relationships among these parameters were examined using Spearman's rank correlation analysis. Additionally, in 55 patients (24 male and 31 female) with complete data from the day of onset, multiple regression analysis was performed. The data of muscle power were handled by the quantification method. The result of Spearman's rank correlation coefficient indicated that the outcome had a positive correlation with age (correlation coefficient = 0.375), CT classification (0.595), neurological grade (0.714), hematoma volume (0.689), a past history of cerebrovascular disease (0.475), the white blood cell count (0.541), and the lactate dehydrogenase level (0.347). The outcome had a negative correlation with muscle power (-0.579) and the cholinesterase (-0.340).(ABSTRACT TRUNCATED AT 250 WORDS)
