[Evaluation of the efficiency of intracranial volume compensation before and after surgical treatment of intracranial hematoma].

On the ground of the clinical status and indicators of intracranial pressure instability and cerebral arterial reactivity the authors evaluated the efficiency of intracranial volume compensatory mechanisms in 21 patients before and after operations for epidural and subdural haematomas and spontaneous intracerebral haematomas. The epidural haematomas in a greater degree but less permanently exhausted the efficiency of the compensatory mechanisms than subdural haematomas and after their removal these mechanisms regained easier their efficiency than after removal of subdural haematomas. In cases of spontaneous intracerebral haematomas the efficiency of the compensatory mechanisms is only slightly decreased.
