The aim of the study was establishing which parameters play a significant prognostic role in acute haemorrhagic stroke in its acute phases (during 30 days from stroke onset). The material included 110 patients with haemorrhagic stroke (HS) treated in the years 1997-1999 at the II Neurology Department, Institute of Psychiatry and Neurology in Warsaw or at the Neurology Department, Hospital in Piła. The analysis of risk factors, fitness before stroke and on the first day of the disease was based on history data. On the first day of the disease the assessment included state of consciousness, brain stem signs, vomiting, stroke type on the basis of clinical condition (according to Oxford classification, OCSP), blood pressure, body temperature measurements, intensity of neurological signs according to Scandinavian scale (SSS). In the blood glucose level, fibrinogen, leucocyte count and ESR were determined. In the first week consciousness state, blood pressure and miction were checked repeatedly. It was found that serious consciousness disturbances, stroke type TACS, POCS and severe not classified stroke, presence of brain stem involvement, low SSS score, high body temperature, high leucocyte count and glucose level were more frequent in patients who died within 30 days after stroke onset. Prognostically important were also instability of blood pressure and urinary incontinence in the first week. All clinical observation and laboratory analyses of prognostic importance in the acute phase of HS can be done in typical hospital settings.
