Fasted Wistar rats were subjected to either a mild mechanical injury, 6 min of transient forebrain ischemia, or a mild mechanical injury followed 1 h later by 6 min of forebrain ischemia. EEG and evoked potentials were assessed intermittently and morphological analyses were performed after 7 days postinjury survival. In all groups complete qualitative(More)
Fasted Wistar rats were given a mild level of traumatic brain injury (TBI) and then subjected to 6 min of transient forebrain ischemia 24 h posttrauma. One group was given simultaneous 1 mg/kg scopolamine and 4 mg/kg phencyclidine intraperitoneally (IP) 15 min before trauma and another group an equal volume of plasmalyte A solution. After 7 days of(More)
Controlled arterial hypotension was applied in 62 hyperventilated patients during neurosurgical operations. Hypotension was obtained using trimetaphan (19 cases), trimetaphan and halothane (32 cases) and sodium nitroprusside (11 cases). It was found that the action of sodium nitroprusside was the quickest and lasted the shortest, which considerably(More)
The purpose of the study was to establish the influence exerted by a supratentorial brain tumour on the EEG correlates of sleep, and to compare the results before and after operation. Five patients were studied (aged 38 to 59 years) who were treated surgically for supratentorial expanding lesions: two cases of meningioma (in left parietal area), two cases(More)
The curves of cerebrospinal fluid pressure (CFP) in the lateral cerebral ventricle during the so called ventricular filling-up test are presented in 6 patients with high-pressure and medium-pressure hydrocephalus as compared with CFP curves obtained in 2 patients with low-pressure hydrocephalus. The method of filling-up test (infusion test) is described. In(More)
Dynamics of the arterial blood pressure changes under the influence of intravenous infusion of sodium nitroprusside (SN) were studied in 12 patients operated on for intracranial aneurysms. Adequate measures were undertaken to avoid blood pressure (BP) changes due to the anaesthetic procedure itself. It was found that the speed of BP lowering corresponded to(More)
A 0.02% solution of sodium nitroprusside was given in intravenous drip infusion for induction of controlled arterial hypotension during intracranial operations. The drug was given to 9 patients operated upon for aneurysms and 2 patients with intracranial meningiomas. It was observed that arterial blood pressure could be easily controlled in this way for the(More)
