title: [Estimation of prognosis in patients with putaminal hematoma].
abstract: In order to determine the factors affecting the functional prognosis of operated putaminal hematoma patients, the relationship between the final outcome and the acute stage clinical factors were analyzed by the use of multimodality analysis method (Hayashi's Qualification Type 2). Forty-five consecutive cases who admitted to and operated on during the last two years were included in this study (30 male and 15 female patients, the distribution of age was 40 to 75 years old). Clinical factors just prior to surgery were collected from the case record and categorized to calculate the Pearson's product moment correlation coefficient against the Glasgow Outcome Scale. Five clinical factors with the correlation coefficient above 0.5 (Edinbugh 2 coma scale (0.85), light reflex (0.67), respiratory status (0.61), age (0.58) and the side of the lesion (0.50) were used to apply the Hayashi's Qualification Type 2 analysis. By this method, each categories are given scores so that the different outcome separate maximally. The correct estimation ratio for outcome was 100% for good recovery, 30% for moderately disabled, 50% for severely disabled and 88% for death, over all correct estimation ratio being 69%. The mean scores for each outcome were 1 +/- 0.01 for good recovery (9 cases), 0.74 +/- 0.32 for moderately disabled (10 cases), 0.6 +/- 0.36 for severely disabled (10 cases) and -0.16 +/- 0.37 for dead (16 cases). There were statistical significance (p less than 0.01) between each outcome except for moderately disabled and severely disabled.(ABSTRACT TRUNCATED AT 250 WORDS)
