A restrospective clinical investigation has been performed to elucidate the relationship between hematoma size in putaminal hemorrhage and blood pressure (BP) changes during the immediate post-hemorrhagic phase in the emergency room (ER). Thirty-seven adult patients brought to the emergency department by ambulance within 6 hours after onset of symptoms with a confirmed diagnosis of acute putaminal hemorrhage on CT have been involved. Two BP measurements during the superacute phase in the ER have been studied: immediately after arrival at the ER (BP-I), and immediately prior to CT examination (BP-II). Patients have been divided into 6 categories: 1) those whose BP decreased with treatment (D+), 2) those whose BP decreased without treatment (D-), 3) those whose BP increased in spite of treatment (I+), 4) those whose BP increased without treatment (I-), 5) those whose BP remained unchanged in spite of treatment (U+), and 6) those whose BP remained unchanged without treatment (U-). Hematoma size has been compared among 5 categories (D+, D-, I-, U+, U-) using factorial ANOVA (analysis of variance). The hematoma sizes have been found to be (D+) 54 +/- 44 ml, (D-) 22 +/- 25 ml, (I-) 102 +/- 58 ml, (U+) 11 +/- 5 ml, (U-) 21 +/- 9 ml (mean +/- S.D.), respectively. (I-) has been significantly larger than any of the other categories (p < 0.001 - 0.05). Additional ANOVA has shown that BP-II in category (I-) was significantly higher than that of the other categories. Patients with putaminal hemorrhage whose BP was elevating during the superacute phase in the ER were shown to have massive hematomas.
